摘要:
本文以油菜蜂花粉及其蜂粮为研究对象,对其常规营养成分、氨基酸和脂肪酸组成进行测定,评价并比较二者的营养价值。结果表明:油菜蜂粮的水分、还原糖和粗脂肪含量显著高于蜂花粉(p<0.05),灰分、蛋白质和总黄酮含量显著低于后者(p<0.05);油菜蜂花粉及其蜂粮中含有8种必需氨基酸,蜂粮总必需氨基酸与总氨基酸的比值(EEA/TAA)显著高于蜂花粉(p<0.05),分别为37.80%和34.74%;油菜蜂花粉和蜂粮的饱和脂肪酸中棕榈酸含量最高,分别为33.81%、33.50%,不饱和脂肪酸中亚麻酸含量最高,分别为32.42%、38.22%,差异显著(p<0.05)。油菜蜂粮是一种优质的必需氨基酸和必需脂肪酸营养源,可以作为一种潜在的原料应用于功能性食品的开发。

Abstract:
In this study,the basic nutritional contents,amino acid and fatty acid compositions of rape bee pollen and rape bee bread were studied to assessment their nutritional value. Results indicated that the contents of water content,reducing sugars and crude fat of rape bee bread were significantly higher than that of rape bee pollen(p<0.05),while the content of ash,proteins and flavonoids were significantly lower than that of rape bee pollen(p<0.05). The 8 essential amino acids were present in rape bee pollen and rape bee bread. The ratio of total essential amino acids to total amino acids(EEA/TAA)in bee bread was significant higher than that in pollen,which was 37.80% and 34.74%,respectively. Palmitic acid levels were found to be the highest of the saturated fatty acid in rape bee pollen and rape bee bread,which was 33.81% and 33.50%,respectively. The highest content of unsaturated fatty acids was linolenic acid in rape bee pollen and rape bee bread,which was 33.42% and 38.22%,respectively with significant difference(p<0.05). Therefore,rape bee bread with higher nutritional value,which was a rich source of both high quality essential amino acids and linolenic acid,can be used to the development of functional foods.
