Conjugated linoleic acids plant oils

Animal fat could be completely or partially replaced by plant oils high in unsaturated fatty acids such as (d-3 fatty acids and conjugated linoleic acids. However, it is difficult to protect these fats from autoxidalion without encapsulation (Josquin, Linssen, Houben, 2012). Moreover, the sausages are softer, and drying is difficult. Hence, plant oils are, at present, mainly used iu the manufacture of spreadable types such as Gamau Teewursf . 

CLA refers to a mixture of positional and geometric isomers of linoleic acid (cis-9, cis-12 octadecadienoic acid) with a conjugated double bond system. The structure of two CLA isomers is contrasted with linoleic and vaccenic acids in Figure 3.1. The presence of CLA isomers in ruminant fat is related to the biohydrogenation of polyunsaturated fatty acids (PUFAs) in the rumen. Ruminant fats are relatively more saturated than most plant oils and this is also a consequence of biohydrogenation of dietary PUFAs by rumen bacteria. Increases in saturated fatty acids are considered undesirable, but consumption of CLA has been shown to be associated with many health benefits, and food products derived from ruminants are the major dietary source of CLA for humans. The interest in health benefits of CLA has its genesis in the research by Pariza and associates who first demonstrated that...
