Fats and oils have numerous applications in food such as in snack foods, milk products, bakery and confectionary products owing to different physical and sensory characteristics of these products. During processing oils and fats undergo various physico-chemical modifications which define the ...
The chemical portion of fats and oils having the greatest nutritional value in livestock rations is the fatty acid component. All fatty acids are high in energy, and some, such as those with specific double bond locations, can have potent and diversephysiological function in body tissues. Variati...

18.4 Chemical properties of fats and oils 1. Hydrolysis Reverse of esterification Forms carboxylic acids (FAs) and alcohol (glycerol) Catalyst = acid or enzyme (lipase) Chemical reactions of TAGs 2. Saponification (hydrolysis in base) Forms carboxylic acid salts (soaps) Na+ = hard soap; K+ ...
[e.g. fi sh oils, olive oil etc.].Fats and oils are insoluble in water but soluble in organic solvents such as hexane (C 6 H 14 ) or tetrachloromethane (CCl 4 ). Since they are water insoluble, they are found in “watery” foods such as milk in the form of an emulsion – ...
