Fresno’s Southeast Asian farmers are on trend with new ‘superfood’

Farmer Vang Thao has been managing a successful farm south of Fresno for nearly 30 years, producing a spectacular array of vegetables – heirloom tomatoes, purple bell peppers, water spinach, bitter melon, Thai eggplant and dozens of others.

Every weekend the family traverses the Grape Vine to set up a visual feast at farmers markets in Santa Monica, Hollywood, Palos Verdes, Torrance and Hollywood. Acclaimed Los Angeles chefs rave about his produce, according to a Los Angeles Times feature story on the Thao family.

Produce like sweet potato leaves, amaranth and black nightshade are essential for families hailing from Vietnam, Laos, Thailand, the Philippines and India who seek ingredients for their traditional cuisine, but the market is limited. Now, small-scale farmers like the Thaos are on the cusp of something with much wider appeal.

One of their crops is moringa, a tropical tree that produces an abundance of fresh shoots to sell at the farmers market booth for $1 a bundle. Moringa is a delicate green that can be added to salads, soups and nearly any other dish. It has a pleasant nutty, earthy and slightly pungent green flavor. While it tastes good, it's the plant's nutrient profile that is commanding attention.

On the internet, moringas are called miracle trees. All parts of the plant are edible – the tender leaves can be cooked or eaten fresh, moringa flowers are considered a delicacy, the tree's young pods can be used like green beans, roasted seeds are said to have antibiotic and antifungal properties. The roots and bark have medicinal potential, but need more study to determine the right dose. A 100 gram serving of moringa greens has more protein than a cup of milk, more iron than a cup of spinach, and is high in calcium, potassium, vitamin C and vitamin A.

Moringa is the Superfood of 2018, according to the trend watchers at SPINS.com. UC Davis nutrition researcher Carrie Waterman is studying moringa's use, production and processing worldwide. She is pursuing moringa for therapeutic applications in treating cancer, HIV and inflammatory bowel disease.

Vang sells small bundles of moringa shoots at farmers markets for $1 each.

Ruth Dahlquist-Willard, the UC Cooperative Extension advisor to small-scale farmers in Fresno and Tulare counties, recognized moringa's potential to supplement income for Southeast Asian farming families who are marketing specialty Asian vegetables and herbs to immigrant communities.

“Moringa is a drought tolerant tree known for its excellent nutritional content,” Dahlquist-Willard said. “We believe it could improve the economic viability of small-scale farms in our community. We are helping small-scale farmers with moringa product development and marketing.”

Supporting farmers growing moringa in marketing the product to new buyers is an objective of the UCCE moringa project, a partnership with the UC Sustainable Agriculture Research and Education Program, which was funded by a California Department of Food and Agriculture specialty crop block grant. Lorena Ramos, the project lead, is working on developing marketing materials, outreach opportunities, and value-added options.

While using moringa is second nature for many immigrant groups, expanding the market includes demonstrating how easily the green can be used in the kitchen. Dahlquist-Willard and Ramos called on another sector of UC Cooperative Extension – the UC CalFresh Nutrition Education Program – for assistance. UCCE offers nutrition education in schools and community settings to children and families eligible for the USDA's nutrition assistance programs. Each year, Fresno State dietetic students serve two-week internships at UCCE. In 2018, one of their tasks was developing creative, healthful recipes incorporating moringa. Among the recipes were overnight oatmeal, pesto, smoothies, guacamole and energy bites – all with moringa.

“We are publishing the best recipes to share with the public to help them add this nutritional green into their diets,” Ramos said.

Recipe cards and moringa samples will be available July 26 at the Fresno Food Expo, where UCCE is hosting a booth to raise awareness about moringa by introducing farmers to Fresno area chefs, buyers and consumers and sharing information about the vegetable's health benefits, culinary versatility and its ability support small-scale farmers in Fresno and Tulare counties.

Fresh moringa can be easily added to many recipes.

Following is a USDA recipe ideal for incorporating moringa:

Grilled quesadilla with vegetables

Ingredients

Nonstick cooking spray
1 medium zucchini, diced
½ broccoli head, diced
1 green pepper, diced
1 medium onion, minced
1 carrot, peeled and grated
16 (6 inch) flour tortillas
12 ounces cheese, shredded
½ cup moringa leaves

Directions

  1. Wash all vegetables.
  2. Collect, dice, shred and measure all ingredients before starting to prepare the recipe.
  3. Spray a large skillet with cooking spray. Add zucchini, broccoli, green pepper, onion and carrot. Cook vegetables on medium heat for 4 to 5 minutes, stirring frequently. Remove vegetables from skillet, and put on a clean plate.
  4. Spray skillet with cooking spray again and place 1 tortilla in the skillet. Top with ½ cup vegetables and 1/3 cup cheese. Sprinkle on fresh moringa leaves.
  5. Place a second tortilla on top. Cook on medium low heat for 2 to 3 minutes or until the cheese starts to melt and the bottom tortilla starts to brown.
  6. Flip over the quesadilla. Cook for another 2 to 3 minutes until tortilla brons.
  7. Repeat steps 4 through 6 to make additional quesadillas
  8. Cut each quesadilla in half or quarters, serve hot with your favorite salsa or other toppings.
  9. Refrigerate leftovers within 2 hours. Eat within 3 to 5 days.

School food: Supporting healthy kids and local food systems

School food service is a multibillion dollar industry that impacts the lives of over 30 million (mostly) low-income students. Every school day and, with increasing frequency, during summer weekdays as well, this industry provides two-thirds of students' meals (breakfast and lunch), as well as snacks, contributing a large portion of the nutrients youth consume throughout their childhoods. To qualify for a free school lunch, a family of three must make less than $26,208 in 2016-17.

School food service directors have a huge charge on their hands: feed kids, every day, with a lot of requirements, for very little money. The current reimbursement rate for free meals provided to students in California is $3.31, which is required to include at least ½ cup of fruit or vegetables, and the choice to select a whole grain food, a protein food, and low-fat or non-fat milk. Elementary school kids from higher-income homes pay around $3 for the same meals.

So, when a canned mandarin from China is more economical than a local pixie tangerine, how does this impact food service directors' decisions to make sustainable and healthy food selections?

According to the San Luis Coastal Unified food service director, Erin Primer, food service directors have a lot of power to make healthy (or not so healthy) selections. Primer is a school food champion, who some have said is “murdering the lunch lady game.” Primer's first venture into institutional food service was in the private industry and catering. She learned how to get things done, how to be competitive and, ultimately, how to serve a lot of food that people want to eat.

Primer credits this background with enabling her to see things more creatively.

“Because of my background with catering, I was never limited by what school food says we can't do," Primer said. "I never let that burden me. When I came to school food, I loved the freedom to problem solve and connect all the dots with all the requirements, and then just feeding the kids.”

How do you feed kids healthy food while considering the broader impact of food purchasing decisions? Primer says it comes down to participation, it is a game of numbers. How many students and families will choose to eat a school meal on any given day? For Primer, that's about 3,000 lunches and 2,000 breakfasts every day - a number she would like to see grow.

What are some strategies to increase participation so more kids are eating school lunch? To Primer, and many food service directors that are rising to the challenge of feeding our next generation, it's about serving good food. It is easy to get stuck in the weeds of the regulatory environment of school food; and, while following the guidelines is incredibly important, it is also important to think about the food you are serving. Primer says she likes to think about the whole plate and what actually makes sense to serve to kids. You have to keep going back to asking yourself: “Will kids eat it?” and “Does it make sense?”

“We started with asking ourselves, does it taste good? Is it good quality? Is it sending the message we want to send? And if it's not, let's not do it, Primer said.

One of the biggest changes Primer has made to her menus is first, getting rid of the junk. In the world of school food, you can find chocolate doughnuts and cinnamon-sugar cereals that meet USDA regulations for the school meal program. In many cases, food processing companies have reformulated popular food items specifically to meet requirements. By adding in whole grains, or reducing the sugar, fat or sodium content in a product, they can be sold at school even if you could never find that same version of the product in the store. When students see these products at school it can send them mixed messages about what should be included as a regular part of a healthy diet.

The next change she made and continues to make includes increasing the purchase of local foods and removing items that can't be obtained locally. She is able to serve local, grass fed beef on the menu in a “blended burger” which includes mushrooms to make it larger, tastier and economically feasible. She also became one of the first school food service directors to use local grains by featuring emmer farro from a farmer that is less than 15 miles from her office. In addition, she has made some waves by replacing bananas on her menu with other local fruits, like kiwi.

Living on the central coast of California, there is an abundance of local foods available most months of the year. However, “local” does not need to be barrier for food service directors. Defining what is “local” or “regional” is up to each district or institution, who should take into consideration the surrounding agricultural landscape, seasons, and what foods are reliably available.

The last, but really important, step that Primer is working on is telling her story. Working with partners in creative ways, Primer is working hard to sell school food to all families in her district, regardless of their incomes. Her goal is to make meals that all kids want to eat and parents want to buy. She has her delivery trucks wrapped in pictures promoting the local foods they serve each day and she talks to local stakeholders, teachers, parents and school board members at every opportunity.

What are we feeding our kids? Where did it come from? How do our purchasing decisions impact our world?

These are the questions being tackled by school and institutional food service directors every day, whether they are aware of it or not. How they choose to answer those questions will have broad reaching impacts on our communities and future generations.

Growers get labor-saving ideas at UC Grape Day

Labor costs about 7 cents per vine for managing the “touchless” vineyard, compared to $1 in the conventional vineyard, says Kaan Kurtural, UC Cooperative Extension specialist.

Will machines replace the romance of the hand-cultivated wine grape vineyard? A “touchless” vineyard was among the latest research on labor shortages, weeds and pest management by UC Cooperative Extension scientists discussed at Grape Day at the UC Davis Oakville Station, located in the epicenter of California wine country, on June 6.

About 200 wine grape growers, vineyard consultants and other industry people attended to learn about the latest UC Cooperative Extension research. Vineyard managers from boutique wineries such as Fork in the Road to Pine Ridge Vineyards to the Fortune 500 wine company Constellation Brands gathered at the research station's experimental vineyard. Several vineyard equipment representatives brought their machines to the field to demonstrate their weeding, pruning and canopy management capabilities.

 

This three-row sprayer was one of four tractor attachments presented.

Addressing labor shortages

To help growers attract and retain farm workers, Monica Cooper, UC Cooperative Extension advisor for Napa County and her research assistant, Malcolm Hobbs, are conducting a survey of agricultural workers to determine the factors that affect job satisfaction. They found the number of female workers in Napa County has increased rapidly since 2013. “Women may be moving into the labor pool to fill vacancies caused by the decline in the number of male workers migrating to the U.S. for agricultural work,” Cooper said.

They plan to provide participating companies with custom recommendations for recruiting and retaining workers.

“We will also be generating a generic summary that will be widely shared with participants and non-participants at the close of the study. For now, we cannot make any general conclusions or recommendations because data collection is ongoing,” Cooper said. “We are aiming to distribute our final report this winter, so stay tuned.”

To help growers reduce their need for hand labor, UC Cooperative Extension viticulture specialist Kaan Kurtural designed a “touchless” demonstration vineyard that is mechanically managed. The mechanized vineyard is one of six trellis systems he is studying for water use, nitrogen use efficiency, yield and fruit quality of the wine grapes.

Viticulture consultant Francisco Araujo said the wine industry relies on UC research, “Finding a way to get maximum quality along with yield levels that will pay for the increasing costs of production is the only way we'll be sustainable now and in the future.”

“We're always looking for ways to improve yield, quality and to reduce cost,” said Francisco Araujo, director of viticulture for Atlas Vineyard Management. “In light of the labor shortage we're facing right now, Kaan is exploring new production systems that include new trellises, mechanization, different types of mechanization from pruning to shoot thinning and trunk suckering. He's obtaining information about how these new trellis systems that he is investigating are going to play with yield and quality.”

The touchless vineyard experiment started out as a demonstration at first, but with grower interest, it turned into a full-blown research project.

“It started as way of saving labor costs, but when we started looking at the physiological aspects of how these plants grow, we saw the benefits from the quality point of view in addition to the labor savings,” said Kurtural, who is based in the Department of Viticulture and Enology at UC Davis.

A traditional vineyard in the Napa area is about a meter or 36 inches above the vineyard floor with vertical shoots held up with wires, which are moved by hand.

Saves water

“We said, ‘Why don't we turn the system upside down?' Grow a tall trunk then put the bilateral cordon about 62 inches above the vineyard floor, that way we can push the rows a lot closer,” said Kurtural, who oversees the 40-acre Oakville experimental vineyard. The leaves grow down to generate the same leaf area as a traditional vineyard, but the leaves in the mechanized vineyard use water more efficiently so the no-touch vineyard requires less water compared to traditional vineyard systems.

“This is a dense system, this is 1.5 meters by 2 meters, roughly 1,340 plants per acre – we're getting by here on a third to quarter acre foot of water,” Kurtural said.

Mechanically removing shoots opens up the canopy to allow more sunlight in.

“It costs us roughly about a dollar in labor operation costs to manage each plant in a traditionally farmed vineyard of roughly about 1,300 plants per acre on the North Coast now,” Kurtural said. “The no-touch plants are costing us about 7 cents in labor operations costs.”

“The biggest expense is pruning, after that we go through what they call trunk suckering, which is also done mechanically here, and after that they will do shoot removal to open up the canopy. That's also done mechanically. After that, if there's need, they will do leaf removal, that's also done mechanically. And one last resort, if there's too much crop here, they will shake off excess berries with a harvester.”

The conventional system yields up to 5 to 6 tons per acre whereas the mechanized vineyard yields 7 to 8 tons per acre.

“These clusters set far fewer berries than a traditionally managed vineyard, but the berry size is also very small, which is what the winemakers like,” he said.

During harvest, grapes picked by machine are sorted on board the harvester so they go into the winery in uniform sizes, whereas hand-harvested grapes have to be sorted on a tray before they are put into the press tank.

“We made wines from these last year and compared to our traditionally farmed vineyards. Until we tell people what it is, they cannot distinguish the quality of the fruit or the wine.”

Weed and pest management

This machine cuts weeds at 1 to 2 inches below the soil surface.

John Roncoroni, UCCE weed science farm advisor in Napa County, discussed options for weed control among young grape vines.

In the past, many vineyards were fumigated before planting for disease control, but it also provided weed control for young vines.

“With the loss of most fumigants for use in vineyards, hand-weeding was often used to accomplish this task,” Roncoroni said. “Increased costs and decreased labor force have made hand weeding impractical. Mechanical cultivation, at this point, is too imprecise – either leaving weeds close to young vines or causing damage by being too close.”

Cartons protect young vines, but “herbicide use on vines less than 3 years old is a risky endeavor,” John Roncoroni cautions.

Covers on young vines allow the use of many post-emergence herbicides to control weeds, but Roncoroni cautioned that application of post-emergence herbicides on vines that aren't protected by mature bark may damage or even kill the vine.

“Herbicide use on vines less than 3 years old is a risky endeavor,” Roncoroni said. “Follow all label requirements, paying special attention to soil and irrigation recommendations.”

Lynn Wunderlich, UC Cooperative Extension advisor for the Central Sierra, and Franz Niederholzer, UC Cooperative Extension advisor for Colusa, Sutter and Yuba counties, demonstrated how to calibrate sprayers and to get uniform coverage when spraying fungicides.

To test spray uniformity, use wettable powder or water sensitive paper on vines, recommend UC Cooperative Extension advisors Lynn Wunderlich and Franz Niederholzer.

In 2016, UC Davis researchers identified the three-cornered alfalfa hopper, Spissistilus festinus, as a vector of grapevine red blotch virus. Cindy Preto, a Ph.D candidate in the UC Davis Department of Entomology who is assisting UC scientists studying the three-cornered alfalfa hopper's biology and host plants, provided an update on their research.

Araujo, the viticulture consultant, said he and his colleagues value the university's research. “Napa Valley is a place where quality is paramount yet more and more we have labor shortage, we have inflation, production costs are going up,” he said. “Finding a way to get maximum quality along with yield levels that will pay for the increasing costs of production is the only way we'll be sustainable now and in the future.”

UC Master Food Preserver volunteers in tribal communities

Throughout Humboldt and Del Norte counties, the UC Master Food Preserver Program is actively engaging with tribal members. In fact, the UC Master Food Preserver volunteers have been “jamming it up” since 2017 with over 15 workshops for tribal community members.

Kella Roberts, of United Indian Health Services, has helped more than 280 community members improve their health and wellness - one jar, one dehydrator, one freezer bag at a time. Their workshops support existing efforts in the tribal communities to empower individuals, families, tribes, and the community to make healthy choices.

Roberts, along with her fellow UC Master Food Preserver volunteers, deserve recognition for coordinating and delivering food preservation classes to new audiences. They've adopted methods to help those with diabetes by limiting the sugar in recipes, and taught four workshops on ginger zucchini orange marmalade and strawberry jam using pectin.

Roberts kept the crunch going by teaching workshops on kosher dills, pickled green beans and pickled beets. Kale chips were another crunchy treat with healthful benefits that were highlighted at a Hands on Health Conference workshop. Other healthy food preservation workshops included smooth applesauce and fruit dehydration.

Strawberry stands sell berries fresh from the field

Nathan Punh, left, talks with UCCE farm advisor Margaret Lloyd, who works with about 60 Mien farms in the Sacramento area.

Slugs, snails, ants, aphids, spider mites and inclement weather conspire against strawberry growers harvesting perfect red berries to sell. 

“Farming is hard work,” said Fam Lee, as she pulled a weed from a row of strawberry plants. Lee and her husband Nathan Punh are among about 60 Mien farmers in the Sacramento area who call on Margaret Lloyd, a UC Cooperative Extension advisor, for farming advice.

Fam Lee examines a strawberry for insect and slug damage. “Although we are not organic farmers, we always want to go with organic,” she said.

“Although we are not organic farmers, we always want to go with organic,” said Lee. “For example, we have slugs and ants, I asked Margaret if it's okay to put organic slug bait around the plant as long as it doesn't touch the berry. She said that's the best way to do. We work closely with our extension staff.”

In the Sacramento area, many of the Mien-owned farms are husband and wife teams. The typical couple farms an acre or two themselves, picking berries to sell the same day at a roadside stand, which provides the family's primary source of income.

Mouang Saetern harvests strawberries.

“Many of them grew up on farms in Thailand or Laos growing vegetables or growing rice or soybeans,” said Lloyd, who serves small-scale farmers in Sacramento, Solano and Yolo counties. “A lot of them come from farming backgrounds so when they came to this country, they also sought out an agrarian lifestyle.”

Some Mien growers had never seen a strawberry before arriving in California, but chose the high-value crop to maximize returns on their small plots of land.

To help Mien growers develop successful strawberry farms, Lloyd updates them on regulations and shares growing tips at an annual extension meeting, visits them at their farms, and records videos demonstrating how to do things such as using compost to fertilize the crop.

Visiting Mien farms makes it easier for Lloyd, right, to demonstrate practices for farmers who aren't fluent in English.

“Because of language barriers, coming out to the farm regularly is a big part of the job,” said Lloyd, who partners with staff from the National Center for Appropriate Technology (NCAT) to assist Mien farmers.

“Once we're on the farm, we can communicate in-person more easily,” she said. “Often times it involves pest identification, so I'll show them how to use a hand lens and how to identify spider mites, aphids and lygus bugs, for example.”

“A lot of them have children who speak English fluently so if they don't speak English fluently, sometimes the children come out and help.”

The UC-patented strawberry cultivar Albion produces large, sweet berries.

For the past five years, Lee and Punh have been growing and selling strawberries at a farm stand on Bond Road, between Bader and Bradshaw, in Sacramento. They grow Albion, Chandler, Santa Rosa and Seascape – sweet, delicate varieties, some of which aren't found in supermarkets because the berries don't store and ship as well. They typically begin harvesting berries at the end of March and pick through July or August, depending on the weather. This year, the first berries were ruined by spring rain and frost.

Savvy consumers will ask for certain varieties by name, Lloyd said. “Chandler is well-loved by consumers for its delicate flesh and sweet flavor. Albion produces larger berries that are also very tasty.”

Established farm stands, like this one on Florin Road at South Watt Avenue, develop a loyal following of customers who eagerly await their opening to buy strawberries.

Because berries sold at the roadside stands are picked fresh daily, the farmers wait until berries are perfectly ripe before picking them.

Monday through Saturday, Lee begins harvesting her strawberries by hand at the break of dawn.

“We start at 5:45, the minute we can see, and we pick until 8 o'clock. That's our goal,” Lee said. “By 8:30, we want to open our stand and we sell until all the berries run out.”

Lee's parents often drive up from Alameda to help pick berries.

Some farm stands offer vegetables, like these red onions, to complement the strawberries.

To extend the farm stand season, some Mien farmers supplement the strawberries with other berries, strawberry jam and vegetables. They grow blueberries and blackberries, tomatoes, peppers and green beans and sometimes specialty vegetables such as bittermelon.

“Growing strawberries isn't easy, but it's enjoyable work,” Lee said.

Lloyd has updated a map showing locations of about 60 strawberry stands in the Sacramento area at http://bit.ly/strawberrystands.

To help consumers find the Mien farm stands, UC Cooperative Extension has created a map showing locations in the Sacramento area at http://bit.ly/strawberrystands.
