Physical and chemical composition of fat

Abstract

Pork fat is a high-nourishing food product which contains such irreplaceable fat acids, as linolenic and arachidonic, which enter the complement of cell nucleus and influence on the recreation of posterity. In fat there is more irreplaceable fat acids than in cow butter. Fat is an obligatory component not only for the production of sausages but also for the feed of people of hard physical work as a high-energy product. Using 30–50 grammes of pork fat in feed provides day's norm in irreplaceable fat acids, that makes 3–6 grammes. The results of experimental works on the study of influence of physical and chemical properties of composition on quality of fat of pigs of different breeds depending on gravimetric standard are given in the article.
