Chemical properties related to the carboxyl group. Edible uses of . guish between different edible fats and oils. The term often refers specifically to triglycerides (triple esters of glycerol), that are the main components of vegetable oils and of fatty tissue . Chemically, they can be divided into four main types - saturated, cis-monounsaturated, cis-polyunsaturated and trans fatty acids. 1 83 three to four phytosterols in all oils: brassicasterol, campesterol, stigmasterol, and β-sitosterol.

The major sources of food lipids (vegetable and animal fats) are outlined, along with their physical characteristics. β-Sitosterol is a major component found in all oils. The determination of the triglyceride composition of animal and vegetable fats and oils provides information which complements that of the fatty acid composition for the identification of these lipids; it also provides limited information concerning the distribution of the fatty acids within the glyceride molecules. Ciency of rural surgery and oil technologies currently in earth in many developing. There are many different types of dietary fats and oils. • Include fats, oils . Regarding the FA composition of backfat (Table 4), there was a significant interaction between oil source and duration of feeding for saturated stearic acid (p = 0.018), monounsaturated palmitoleic acid (p = 0.042), and polyunsaturated linoleic acid (p = 0.002) and ALA (p = 0.039). The listing of vegetable oils includes several hydro- genated vegetable oils or oil blends that are commercially marketed as salad and cooking oils. Applications of some of the newer research methods are described and discussed. Oils and fats provide 10 to 30 per cent of our daily energy intake.
