Feed grade fats

Unsaponifiable Matter in Fats and Oils, Including Marine Oils (Ca bb-5, 3) determines substances dissolved in fats and oils that cannot be saponified (turned into sodium salts) by the usual caustic treatment, including higher aliphatic alcohols, sterols, pigments, and hydrocarbons. This method is not suitable for marine oils or feed grade fats. 

Because of these situations, the production of the major portion of feed grade fats and some oil-bearing feedstuffs is likely to continue regardless of their market prices. However, future prices will reflect (1) domestic competition between feed, oleochemicals, and detergent industries needs (2) opportunities to ship into global markets and (3) abilities to import lower cost fats like palm oil and stearin.

Edible animal fat in the United States can be rendered only in food grade plants under inspection of the U.S. Department of Agriculture (USDA) (1). The majority of tallows and greases used domestically in animal feeds and pet foods are feed grade. The National Renderer s Association (NRA) describes rendering as a process that... 

Ester, feed grade (33.4), is the product consisting of methyl, ethyl, and other nonglyceride esters of fatty acids derived from animal and/or vegetable fats. It consists predominantly of the ester and must contain not less than 85% total fatty acids, not more than 10% free fatty acids, not more than 6% unsaponifiable matter (2% for methyl esters), and not more than 1 % insoluble matter. Its source must be stated in the product name, e.g., methyl ester of animal fatty acids or ethyl ester of vegetable oil fatty acids. Methyl esters must contain not more than 150 ppm (0.015%) free methyl alcohol. If an antioxidant is used, the common name or names must be indicated, followed by the words used as a preservative. This feed fat includes FDA regulation 573.640 ... 

Hydrolyzed Fat or Oil (Feed Grade) is obtained in the fat processing procedures commonly used in edible fat processing or soap making. It consists predominantly of fatty acids and must contain, and be guaranteed for, not less than 85% total fatty acids, not more than 6% unsaponifiable matter, and not more than 1% insoluble impurities. 

Other Whole Oilseeds. Various oilseeds have been fed whole, or dehulled, when available for feed at competitive prices or in grades substandard for extraction but still wholesome for feeding. Examples include safflower (Carthamus tinctorius), fat content 35%, dmb and oil-type sunflower seed fat content 44%, dmb. Currently, interest is high in feeding whole canola seed (41 6% oil) in Canada and northern European countries. Double-zero strains of Brassica napus (rapeseed, oilseed rape, swede rape, and Argentine rape) and Brassica campestris (turnip rape, oil... 

As will be described in the next subsection, the use of chemical flotation in this application may be less desirable considering other processes. DAF has been applied effectively as a trimmer process following other treatment facilities for FOG removal requiring a 100-mg/L FOG limit, which can sometimes be accomplished using food grade-approved polymers. In that event, the recovered materials can sometimes be sold as a low-grade feed fat rather than disposed of as a waste sludge. 

Abstract Studies have shown that the production of polyhydroxyalkanoate (PHA) from plant oils is more efficient than from sugars in terms of productivity. Among the various plant oils, pahn oil is the most efficiently produced oil in the world. The main application of pahn oil is as a source of dietary fat. The conversion of food grade substrates to non-food materials is of concern because of the increasing need to feed the rapidly growing human population. Therefore, the by-products of the plant oil industry may be a better feedstock for PHA production. Alternatively, non-food grade oils such as jatropha oil can be developed as a feedstock for PHA production. This chapter looks at the potential of jatropha oil as a possible feedstock for the biosynthesis of PHA.

The mechanism of induction of low-grade chronic inflammation that accompanies HF-diet-induced obesity was demonstrated to be dependent on TLR-4. Interestingly, in the absence of TLR-4/CD14 receptor for LPS, no low-grade chronic inflammation and insulin resistance were induced by HF feeding in mice. Recently also TLR-2 and TLR-5 were shown to be involved in the innate immune system activation that is responsible for the inflammation induced after HF diet. These results confirm gut microbiota implication in the onset of metabolic disorders associated with obesity. Moreover, in animal studies at least, this high-fat-induced metabohc endotoxemia and subsequent metabolic disease may be reversed using prebiotic dietary fibers and certain bacterial supplements...
