Comparison of Lipids of Polished Rice Endosperm with Rice Starch

抄録

Lipid constituents of polished rice endosperm and of rice starch were examined each other. The appreciable difference of lipid classes was revealed that rice starch had more contents of free fatty acid and lysophosphatidylcholine than those of rice endosperm. Concerning their fatty acid dompositions, large amount of palmitic acid was detected in polar fraction of both the material. Similar fatty acid patterns, being chiefly composed of linoleic, palmitic and oleic, were found in total and neutral fractions of both the material.
