对巴西橡胶籽进行了组份分析,测定了净纤维、氨基酸和矿物质含量。详细分析了种籽的抗胰蛋白酶活性、氰化物、植酸和单宁的含量。 种仁(干基)平均成份测定结果是,粗蛋白为21.5％,粗脂肪为50.2％,粗纤维为6.5％,灰分为3.6％,碳水化合物为18.2％。对氨基酸含量范围进行分析并与(NAS)和(NRC)的参考蛋白质模数比较,赖氨酸、异亮氨酸和苏氨酸含量少。种仁微量元素适量,但钙和磷含量少。 新鲜种仁样品含氢氰酸毒素含量为(164毫克/100克干重),经贮存和蒸煮,绝大多数氰化物消失。植酸盐的磷(占总磷的37.5％)含量相对高,可能会进一步激化种仁含磷量低带来的矛盾,导致钙与磷极度不平衡。在种仁中未能测出抗胰蛋白活性或单宁。由于橡胶籽中含抗致育因子,以及收集与贮藏的困难,在正常境况下,以其作为一种人类食品是不大现实的。
The components of the Brazilian rubber seeds were analyzed and the net fiber, amino acids and mineral contents were determined. Antitrypsin activity, cyanide, phytic acid and tannin contents of seeds were analyzed in detail. The kernel (dry basis) average composition was determined to be 21.5% crude protein, 50.2% crude fat, 6.5% crude fiber, 3.6% ash, and 18.2% carbohydrates. The range of amino acid content was analyzed and the content of lysine, isoleucine and threonine was less than that of reference protein (NAS) and (NRC). Seed kernel trace amount, but less calcium and phosphorus content. Fresh seed kernels contain hydrocyanic acid (164 mg / 100 g dry weight) and most of the cyanide disappears after storage and cooking. Phosphate (37.5% of the total phosphorus) content is relatively high, may further intensify the contradiction caused by the low phosphorus content of the seed, resulting in extremely uneven calcium and phosphorus. No antitrypsin activity or tannin was detected in kernels. Because rubber seeds contain anti-fertility factors and difficulties in collection and storage, it is not realistic to use them as a human food under normal conditions.
