Processing meat determinant factors

Preservation of IM meat is complex in nature. The identified stabilization operations/treatments in processing, water activity, and storage temperature of IM meat are never greater than those for other preserved meats (Leistner, 1987). The specific preservation procedure or step for each empirical product cannot be taken for granted, but must be determined by experimentation. The possible involved consequence and/or synergistic stabilization factors developed in the preservation procedure should be subjected to more scientific scrutiny. 

Research to determine the benefits of CLA for humans will present a unique challenge in the next few years. It will certainly require the improved and complementary methods of CLA and trans FA analysis to evaluate the biological effects of dietary supplements to determine the true effects of CLA in humans. In some studies the presence of CLA in human bodies and those produced by bacteria in the gut may need to take into consideration. The CLA research to date in humans has focused mainly on the effects of rl0,fl2-18 2 rather than on c9,t 1-18 2, the major CLA isomer present in the milk and meat of ruminants. This would appear to be due to the readily available source of commercial CLA preparations compared to pure c9,tl 1-18 2. Commercial CLA preparations consist of an equal mixture of t 0,c 2-18 2 and c9,rl 1-18 2. On the other hand, the rl0,cl2-18 2 isomer is generally present only in trace amounts in milk fats, while some ruminant fats may contain more of the CLA isomers. The true response, if any, of c9,fl 1-18 2 in humans remains to be determined. Several cohort studies have shown a significant reduction in risk factors associated with the consumption of diets high in dairy products and certain types of cancers but not with others. It remains to be seen if the benefits were due to c9,rl 1-18 2, other components in dairy products, or synergistic processes. Regardless of whether CIA s apparent benefits can be translated to humans, it is likely that CLA, as a model test object, will be used in the future in many more studies related to major maladies such as cancer, atherosclerosis, diabetes, etc.
