Chemical Composition and Nutritional Value of Palm Pollen Grains
نویسنده
چکیده
The objective of the study was to determine the chemical composition and nutritional value of palm pollen grains. The proximate chemical composition, vitamin, mineral, amino acid and fatty acid contents of palm pollen grains were analyzed. The results obtained showed that the values of the proximate chemical composition of palm pollen grains were moisture (28.80%), ash (4.57%), crude fiber (1.37%), crude fat (20.74%), crude protein (31.11%) and carbohydrate (13.41%). Palm pollen grains contained a logical amount of vitamins A, E and C. They are a good source of minerals such as B, Zn, Se, Fe, Mo, Cu, Mn, Co and Ni. Leucine and lysine (3.34 and 2.95 g/100 g dry weight, respectively) were the major essential amino acid constituents. The predominant fatty acids of palm pollen grains were palmitic (C16:0), linoleic (C18:2) and myristic (C14:0) acids. In conclusion, palm pollen grains are a good economic nutritional source can be used as human food supplements.
