The food also contains other proteins e.g. from meat, fish, whey, soya, sodium caseinate or cereals. The microbial protein -is obtained e.g. from the culture of Saccharomyces cerevisiae on paraffin gas oil, from Micrococcus cerficans on slack wax, Achromobacter xerosis on . N-octane and tetradecane, or Candida lipolytica on heavy gas oil. Minerals, vitamins and surfactants may be included in the culture medium. After removal of excess hydrocarbons the synthetic protein may be mixed with other ingredients and extruded in fillet form. The final product may be low moisture (below 12%) in the form of meal or biscuits, intermediate moisture (15-30%), or high moisture (canned). The synthetic protein may form 10 to 70% of the final food composition. Among other ingredients named in the examples are oats, milo, skim milk, wheat germ and middlings, corn bran and germ, fish meal, alfalfa, beet pulp, dextrose, corn flour, sodium caseinate, chicken fat, mono- and di-glycerides, carboxymethyl cellulose, torula yeast, bone meal, cracked barley, cod liver oil, onion powder, ground meat, beef tallow, sucrose, sorbitol, garlic, colourings, whey, molasses, brewers grains, soya hulls, cod, corn syrup solids, ground sheep lungs and rice and wheat flour, as well as many named inorganic and organic salts and other compounds. |
