苹果籽营养成分测定_洪庆慈 . Analysis of Nutritional Composition of Apple Seeds

Abstract

After the apple seed kernel being peeled, it was extracted by ether. Then the crude oil and its fatty acid composition,crude protein and starch of defatted kernel powder were quantitatively analyzed. The results indicated that the kernel extractionwas 69.36%, the ratio of crude oil of the kernel was 28.9%, the contents of oleic and linoleic acids were 33.6% and 55.5%respectively and the contents of crude protein and starch in the kernel were 48.72% and 5.01% respectively. Besides, thequalitative tests were also made on the methanol-extract materials, while some phenolic reducing compounds materials andglycosides seemed present in the apple seed kernel.
