摘要: 苹果籽经皮仁分离,已醚提取,对其出仁率、粗脂肪含量、脂肪酸组成、蛋白质含量和淀粉含量进行了测定。结果表明,苹果籽出仁率为69.36%,籽仁含油率为28.9%,其中主要脂肪酸油酸和亚油酸的含量分别为33.6%和55.5%。籽仁中含蛋白质和淀粉分别为48.72%和5.01%。甲醇提取物含量为10.4%,定性试验表明其中很可能含有酚性的还原物质和糖甙等物质。

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.
