Keeping Animal Protein Natural

… Yet safe, affordable and on-trend. These are the challenges faced by processors of meat, poultry and seafood.

"Naturalness" and meat brings out the irony in salt. "Salt is one of the few ‘clean' things on the label," says Janice Johnson, applications leader at Wayzata, Minn.-based Cargill Inc.. Cargill is both an ingredient supplier and one of the country's biggest processors of meat.

In addition to contributing its own flavor, "Salt contributes a nice flavor enhancement to other ingredients in the product," she continues. "Salt has been very important in the preservation of meats and keeping microorganisms in check, so the preservative aspect has to be addressed. Salt also increases the binding of meat. These solubilized proteins help increase the yield and keep the particles of the meat sticking together and sticking of the fat as well."

So when product developers try to remove salt and otherwise reduce sodium in meat products, they must keep an eye on other functional issues, she warns.

Welfare state
"The future of meat, poultry and fish will be complicated by the challenges of the new issues in the arena of animal welfare," says Joe Regenstein, professor of food science and head of the Cornell Kosher and Halal Food Initiative. "Animal welfare, sustainability, the environment and similar issues are on a collision course with consumer perceptions of what they think is best. It is clear the different flesh-food products have different carbon footprints, and this has important long-term implications for the balance between the various commodities, as more life-cycle analyses are presented.

"Unfortunately some of these show that beef does not compete well," continues Regenstein. "At the same time, many of the issues that consumers — typically middle- and upper-middle class consumers — are most concerned about are issues that significantly raise the price of animal products without necessarily providing the benefits the consumer thinks are presented."

According to Regenstein, such "good thinking" is counterintuitive to that which most of us assume at first glance. This disconnect seems to be widening between consumers and the reality of modern agriculture, although the animal agricultural industry finally seems to be trying to address this divide by becoming more active in the public arena. But this catches the processor in the middle.

Regenstein notes that recent work by Jude Capper, assistant professor of dairy science at Washington State University, Pullman, Wash., shows that the lowest carbon footprint comes from grass-fed beef that's been finished off with high energy rations. "This is an example of how good analyses can give counterintuitive answers."

Go fish
The consumer wants the same quality from the sea as from the land. "In the past 10 years, a trend toward buying local and sustainable seafood seems to have caught on," says Wayne Heikkila, executive director of the Western Fishboat Owners Assn. (WFOA), Redding, Calif.

"Regional fish promoted as such — Copper River king salmon, California king salmon — have been very successful and prove consumers are willing to pay more for local, sustainably produced products," he says. Consumers view wild-caught fish as a natural counterpart to free-range animals.

"The demand for wild-caught fish is growing slowly but steadily," says Heikkila. "It's a matter of educating the consumer and getting local processors to make it available for the U.S. market. It is still easy for a processor to buy fish off a boat and put it into a container for a per-ton fee then send it halfway around the world. WFOA is educating the U.S. public to raise demand and make the U.S. market a viable option for U.S. fishermen, processors and the consumer."

More and more locally fished albacore tuna is reaching consumers through retailers such as Whole Foods and others. It also is hitting shelves in value-added forms, not just cans. "Once consumers realize tuna can be eaten without being canned, they seem to like it and buy it," continues Heikkila. "It has better flavor, greater nutritional value such as high omega-3 content, while being a reasonably priced source of protein."

Independent research has demonstrated that the smaller albacores caught by U.S. trollers based on the West Coast have lower mercury levels than the larger longline-caught albacore, along with higher levels of EPA and DHA omega-3 fatty acids. WFOA is dedicated to educating the public on the health and nutritional benefits of its sustainably caught product.

Kwik Pak Fisheries, a community-based business formed by six local villages near the Yukon River near Anchorage, Alaska, takes wild caught and sustainable very seriously. After all, subsistence fishing has been the mainstay of the Yupik people for generations. Today, income derived from commercial fishing helps them to preserve their longstanding traditions.

"Yukon River salmon is a very special fish," says Ruth Carter, Kwikpak Fisheries' marketing and sales manager. "Caught at the mouth of the Yukon River in preparation for its long journey to the spawning grounds, Yukon River salmon has the highest omega-3 content of any seafood found in USDA databases. In addition to its nutrition benefits, it tastes great."

If there's a "hot fish" today, barramundi is it. National Geographic declared it "a farmed option that can save depleted species."

Australis Aquaculture, Turners Falls, Mass., "began with a better idea," according to Carol Devine, vice president of marketing. Instead of simply farming a popular fish, they sought the perfect fish to fit sustainable farming.

But it's not just any aquaculture set-up. Shunning the highly controversial outdoor pens and cages typically used by fish farms, Australis developed one of the world's largest and most ecologically friendly indoor recirculating systems to re-create barramundi's natural habitat.

Environmental controls and specialized natural feed that contains no hormones, antibiotics or colorants ensures the healthfulness of barramundi and leaves them completely free of mercury, PCBs and other contaminants. Also, the barramundi's ability to synthesize omega-3 fatty acids from grain-based oils qualifies it for FDA's highest nutritional designation as an "excellent source" of omega-3 oils.

It's hard to discuss meat, poultry and seafood processing without considering extenders, specifically soy. "Where food technology can allow it, adding soy proteins to meat products can make them affordable without compromising on quality," says Eran Shani, regional marketing manager for Asia, the Pacific, Africa and the Middle East for Solbar, Oakdale, Minn.

"Solbar has developed soy products to specifically provide texture, protein and functionality, allowing them to replace meat with equally good quality protein while binding water, or water and fat, where necessary," he says. "Solbar's textured products also can absorb and retain flavors with either water or brine. The amino acid score — meaning the protein's food value to the human diet — of our products is nearly 100 percent," he adds.

As the protein market changes to accommodate economy and intensified consumer scrutiny, suppliers must step up to the plate literally and figuratively to hone their technological know-how to meet those meaty challenges.

"In the short term, processors are going to have to provide products that might violate some of the best science and what is best for the environment," says Cornell's Regenstein. "But in the long term, consumers are going to need to be taught more about modern agriculture and its benefits, and why certain practices make sense."
