Stephanie Clark is determined to make Iowa the next great cheesemaking state.

“We do have a number of really good cheesemakers around here, and I think it’s time we make people more aware of it,” she said.

Clark — an associate professor in food science and human nutrition at Iowa State University who goes by the email “milkmade” — is one of the state’s premier leaders in promoting Iowa cheese. Her efforts were key in bringing an international cheese conference to Iowa, forming a new guild that connects the state’s dairy professionals, and co-founding a statewide dairy products showcase.

She is a co-chair of the American Cheese Society’s annual international conference, Cheese in the Heartland, which will be held July 27 to 30 in Des Moines.

The conference is a chance to showcase Iowa’s cheeses to the world. It’s expected to attract more than 1,200 cheese industry professionals and experts from around the world. The conference’s annual competition, for which Clark has served as the technical adviser since 2011, will showcase more than 1,700 entries.

“That’s a big deal, for us to win that bid,” Clark said. “Cheese lovers will be descending on Des Moines!”

The Festival of Cheese at the end of the conference will open an international cheese selection to the general public for sampling and purchase. The festival begins 7 p.m. July 30 at the Iowa Events Center

Improving Iowa dairy products

Clark’s passion for dairy products traces back to growing up on a Massachusetts farm with her first pet, a Nubian dairy goat named Hillary. 

“I was involved in 4-H through my youth, but did not know food science was a career option until my sophomore year in college when I asked my adviser if I could do undergraduate research with goat milk,” she said. “I was sent over to food science, and started taking classes there.” 

Clark has helped many Iowa dairy farmers, companies, and consumers make smart choices. While teaching at Iowa State, she also consults dairy farms and companies on production, quality, and safety.

“That’s what I think a land-grant institution should do,” she said. “I think we should answer those calls and help troubleshoot. A half-hour phone call helps a lot. If I can help solve their problem, it saves them a lot of money. It feels good to be able to do that.”

Connecting cheesemaker to cheesemaker

By connecting with dairy professionals all over the state, Clark saw a need to form a new professional association: the Iowa Cheese and Cultured Dairy Products Guild.

The guild provides a networking and education outlet to in-state sellers, buyers, makers, and enthusiasts of cheese and dairy products. More than 20 members representing independent artisans, farms, and major companies meet monthly.

“We’re trying to create a network so they can share experiences and thoughts,” said Kevin Stiles, the senior vice president of business development for Midwest Dairy Association. “It’s amazing how the best learning can take place cheesemaker to cheesemaker.”

The guild will play a large role in ensuring the success of Cheese in the Heartland. Members will volunteer, lead tours, and present Iowa’s cheeses at the competition and festival.

“It creates overall enthusiasm for the cheese industry in the state,” Stiles said. “We see the guild as a way to showcase Iowa-made cheeses.”

Dairy products showcase

In August, Clark will spearhead another passion project she co-founded: the Iowa Quality Dairy Products Showcase.

Now in its second year, the showcase features cultured dairy products, goat and sheep cheeses, and cow cheeses from Iowa companies. Winning cheeses are displayed at the Iowa State Fair. Nine companies entered last year’s competition.

“We’re judging their products and providing them with valuable feedback to improve the quality of their products,” Clark said.

Stiles, who co-founded the guild and dairy products showcase with Clark, said both ventures aim to increase education, food safety, and marketing for Iowa’s 17 cheesemakers and its artisanal cheeses.

“We have a number of large cheesemakers, but also a growing farmstead and artisanal cheese industry too,” he said. “We see an opportunity for the growth potential of artisanal cheeses. It’s been a really good partnership with Stephanie to further build upon the enthusiasm and camaraderie amongst the Iowa cheesemakers.”

Steps in the right direction

Iowa hosting one of the foremost dairy conferences in the world will help encourage development of dairy farming in the state, said C.J. Bienert, the owner of The Cheese Shop of Des Moines who’s also a co-chair of the international cheese conference.

“The conference might just give traditional Iowa farmers that encouragement that they need to take the next step, put in the infrastructure and investment, and start making cheese,” he said.

He explained that other well-known dairy producing regions began as traditional farming areas as well.

“How did Wisconsin become such a great dairy state?” Bienert said. “They used to farm wheat and they had to reinvent themselves. Dairy farming is a way of cash-flowing grass.”

Some corn and soybean farmers are changing their operations and raising cattle for beef production. While not a direct line to cheesemaking, Bienert said animal husbandry is a step in the right direction.

“My dream is that these businesses will start here,” he said. “Iowa is affordable and centrally located, so it makes a lot of sense. I think that we’re posed to see a growth in artisanal products.”

AMES, Iowa – A simple change in diet could boost vitamin D levels for millions of Americans suffering from Type 2 diabetes, according to new research from Iowa State University published in the Journal of Agricultural and Food Chemistry. 

Vitamin D is important for bone health and protecting against cancer and other diseases, but diabetics have trouble retaining it and other nutrients because of poor kidney function. A team of Iowa State researchers found diabetic rats fed an egg-based diet had higher concentrations of vitamin D, improved blood glucose levels and gained less weight.   

Iowa State researchers are most interested in 25-hydroxyvitamin D-3 (25D) – the form of vitamin D in the blood that reflects vitamin D status. For that reason, it made sense to test eggs in the diet rather than other foods containing vitamin D or a supplement.  

“Eggs are the richest source of 25-hydroxyvitamin D-3 in the diet, and there isn’t any conversion required to make it into the blood. If you take it in a supplement or food fortified with vitamin D, it has to be converted to that form,” said Matthew Rowling, an associate professor of food science and human nutrition.

The variation in results was significant. Blood glucose levels dropped nearly 50 percent for diabetic rats on an egg-based diet compared to diabetic rats fed a standard diet. Concentrations of 25D were 148 percent higher for the egg-fed group and plasma triglyceride concentrations – a risk factor for cardiovascular disease – dropped 52 percent.

Rowling and colleagues Kevin Schalinske, professor of food science and human nutrition, and Samantha Jones, a graduate research assistant, are still working to understand why more vitamin D is retained from eggs than supplements. They say it may be related to other components found in eggs. 

Don’t skip the yolk

Eggs are not only a good source of vitamin D and other nutrients; they are also inexpensive and readily available. However, researchers say you need to eat the whole egg. 

“If you just ate egg whites you wouldn’t get any of the vitamin D, because the 25D is only in the yolk. The whites are fine if you’re focused just on protein, but the nutrients are all in the yolk. From a vitamin D standpoint, you want to consume the whole thing,” said Jones, lead author of the paper. 

The next step is to determine the minimal amount of eggs needed in the diet to yield a benefit. The study was designed to replace protein in the diet, so the rats were fed the equivalent of 17 to 18 eggs daily. However, based on the results and the severity of the rats’ diabetes, researchers expect a much lower dosage will be effective in humans. They also want to know if health benefits are enhanced when additional dietary constituents that promote the maintenance of vitamin D status and reduction of diabetic symptoms, such as fiber, are added to the diet.

“You may need even less egg if you combine it with something else that does not provide vitamin D per se, but rather protects the kidney and prevents loss of vitamin D,” Schalinske said. “We want to make sure we understand what’s going on with egg consumption and promoting vitamin D balance and make sure there’s a linkage to outcomes whether it’s bone health or kidney health.”

Gar Yee Koh, a postdoctoral research associate at Tufts University, also contributed to this paper. The research was funded by the Egg Nutrition Center.

Food Science Junior, Michaela Minock (left) and Culinary Science Senior, Haley Brown (right) create recipes for cookbook to utilize damaged crops.

Food Science and Human Nutrition faculty and students are working with Agriculture and Natural Resources Extension and Outreach at Iowa State University to help create a cookbook that will utilize crops damaged by spotted wing drosophila due the rapid spread of this invasive pest this year. The spotted wing drosophila is a fruit crop pest that attacks healthy ripening fruit, just as it is reaching maturity.

The cookbook will provide recipes for damaged berries such as, blackberries, raspberries, strawberries and aronia berries, a super berry with colossal antioxidant power. Students have developed over 150 recipes with berries affected by spotted wing drosophila. Recipes include: blackberry barbecue sauce, raspberry vinaigrette, aronia oatmeal cookies, strawberry and cream cake, and raspberry applesauce.

The berries are gathered and examined by an outside source before being sent to FSHN students working in Dr. Angela Shaw and Dr. Lester Wilson’s food testing laboratories. The berries are being sent by Iowa farmers struggling with damaged crops. Joe Hannan, Commercial Horticulture Specialist with ISU Extension and Outreach, collects the berries to evaluate severity of damage following FDA procedures. Berries are collected, extracted and weighed before being sent to Dr. Wilson and Dr. Shaw.

FSHN students work in their labs to process berry samples in baked and value added foods. Students create and test recipes for deviation in taste, texture, color and overall visual appearance. The majority of berries are turned into sauces, combined into baked goods, sauces and condiments, pureed, and mixed with many other ingredients.

Food Science Junior, Michaela Minock, emphasizes that the damaged berries can still be put to good use.

“We don’t want the berries to go to waste. A lot of farmers last year had up to a few acres wiped out and they couldn’t sell any berries because of the damage.”

Even if not sold fresh, consumers can still eat berries, preventing them from going to waste.

“This project benefits the farmers growing these berries, and it gives the students first-hand experience in research, product development, quality evaluation, and shelf life determination,” said Dr. Wilson. “This will help them throughout their careers.”
