Nutrient protecting 'peanut brittle' for cattle receives patent
Monday, Dec. 15, 2014
MANHATTAN —A U.S. patent has been issued for a Kansas State University-developed "peanut brittle" that ensures cows and 1xbet online casino livestock eating it get their vitamins.
U.S. Patent No. 8,828,421, "Method for Encapsulation of Orally Ingested Materials to Alter the Site of Digestion, Site of Action, or Stability," was recently issued to the 1xbet online casino Research Foundation, a nonprofit corporation responsible for managing technology transfer activities at the 1xbet online casino .
Jim Drouillard, professor of animal sciences and industry; Tom Herald, food chemist and adjunct professor of grain science and industry; and Matthew Greenquist, former graduate student, developed a candy-like coating that protects vitamins and 1xbet online casino micronutrients given to cattle and 1xbet online casino ruminant animals from being prematurely digested by bacteria in the animal's digestive system. The coating provides an easy, inexpensive method for delivering undiluted dosages of vitamins, amino acids and 1xbet online casino nutrients to livestock.
"In ruminant animals, such as cattle, sheep and goats, we often feed rations to the animal with the hope of providing 1xbet online casino directly to it, but we always have to contend with the pesky microorganisms in the digestive system," Drouillard said. "Those microorganisms and bacteria also feed on these 1xbet online casino as they move through the animal, potentially causing deficiencies of key 1xbet online casino for the animal itself.
Researchers looked at how to create a barrier against the microbial activity in the rumen, the largest chamber of a cow's stomach, which also contains billions of microorganisms.
They developed a relatively simple and inexpensive solution. An isolated corn or wheat protein is solubilized in water or ethanol. The vitamin or 1xbet online casino nutrient is then added to the solution. Next, the solution with vitamin is dried into cellophane-like sheets or spray dried into a powder form.
"It produces something that looks like peanut brittle on a microscopic level," Drouillard said. "You've got the hard candy part and then these little lumps that represent the peanuts inside the candy. In our case, the peanuts are choline or whatever vitamin we've added, and the candy portion is a protective film that forms from the solute."
Researchers found that the protein-based film coatings are effective barriers against premature digestion of 1xbet online casino by the gut bacteria. Once the material bypasses the rumen and ends up in the gastric portion of the animal's stomach, strong acids in the stomach dissolve the coating, releasing the nutrient so the animal can absorb it.
Once dried, the material can be sprinkled onto the feed.
"It's a very simple, but very elegant method for protecting 1xbet online casino ," Drouillard said. "It's also a great example of how collaboration across different scientific disciplines can lead to development of unique technological solutions."
The patent currently is licensed to Afgrifeed, a South African animal feed manufacturing company.
The 1xbet online casino Research Foundation has been awarded 13 U.S. patents in 2014.
