为综合开发与利用野生银果胡颓子的果实,于2016年6月底对其果实的物理性状与营养成分进行分析测定。结果表明,银果胡颓子果实可食率为78.85%,糖酸比为4.92;Vc含量为8.12 mg·g~(-1),氨基酸总量达1.21%,含量最多的氨基酸为天冬氨酸(0.196%),其次是谷氨酸(0.125%)和组氨酸(0.111%);种子蛋白质含量为24.76%,远高于果肉中蛋白质的含量(1.40%);矿质元素以钾含量(2423.08 mg·kg~(-1))最高,其次为钙含量(380.56 mg·kg~(-1))。果实具有较高的食用价值和开发潜力。
In order to comprehensively develop and utilize the wild fruit of Elaeagnus bungei, the physical properties and nutritional components of its fruit were analyzed and determined at the end of June 2016. The results showed that the edible fruit yield of Elaeagnus nigra was 78.85%, the ratio of sugar to acid was 4.92, the content of Vc was 8.12 mg · g -1, the total amount of amino acids was 1.21%, and the most abundant amino acids were Aspartame (0.196%) followed by glutamic acid (0.125%) and histidine (0.111%). The content of seed protein was 24.76%, much higher than the content of protein in pulp (1.40%). 2423.08 mg · kg -1), followed by calcium (380.56 mg · kg -1). Fruit has high food value and development potential.
