In this study, the macronutrients and micronutrients of pH 6.8, 8.0, 9.5, and 11.0 extracted soybean oil bodies (OBs) were examined, revealing that soybean OBs might be used as a natural carrier for bioactive components (unsaturated fatty acids, phospholipid, tocopherol, and phytosterol). pH 6.8 extracted OBs (dry basis) contained 85.88% neutral lipid, 8.18% protein, and 5.85% polar lipid (mainly phospholipid) by gravimetric analysis. The percentage of neutral lipid was increased, while those of protein and polar lipid were decreased with increasing pH. Tocopherol (about 75 mg/100 g neutral lipid of OBs) was not affected, while phytosterol was decreased (136 to 110 mg/100 g neutral lipid of OBs) with increasing pH. The detectable total monosaccaride (galactosamine, glucosamine, and glucose) content of extracted OBs was low and also decreased (35.80 to 6.13 mg/100 g neutral lipid of OBs) with increasing pH. The protein of extracted OBs had higher percentage of essential amino acids than soybean protein isolate with tryptophan and methionine as limited amino acids. The fatty acid composition of extracted OBs was rich in linoleic acid (about 59%), oleic acid (about 20%), and α-linolenic acid (about 7%). CONCLUSIONS Oil bodies (OBs) from soybean and other plant seeds are greatly examined owing to their potential utilizations in food ingredients. The determination of its macronutrients and micronutrients would be very meaningful for its efficient utilization in the future.

UI MeSH Term Description Entries
D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed) Lipid
D009753 Nutritive Value An indication of the contribution of a food to the nutrient content of the diet. This value depends on the quantity of a food which is digested and absorbed and the amounts of the essential nutrients (protein, fat, carbohydrate, minerals, vitamins) which it contains. This value can be affected by soil and growing conditions, handling and storage, and processing.

D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid
D005227 Fatty Acids Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED).

D012639 Seeds The encapsulated embryos of flowering plants. They are used as is or for animal feed because of the high content of concentrated nutrients like starches, proteins, and fats. Rapeseed, cottonseed, and sunflower seed are also produced for the oils (fats) they yield.
