Study was conducted to determine the biochemical constituents in coconut (Cocos nucifera L.) haustorium, a spongy tissue formed during coconut germination. Results indicated that 100g of dried coconut haustorium contained 1.05±0.2% ash, 44.2±4.6% soluble sugar, 24.5±3.2% starch, 5.50±0.3% protein, 1.99±0.9% fat, 5.72±0.4% soluble dietary fibre, 20.3±1.9% insoluble dietary fibre, and 146±14.3mg phenolics. Mineral profiling showed that it contained 145±8.6, 104±9.6, 33.9±8.2, 30.9±1.9, 9.45±2.1, 0.292±0.1, 2.53±0.2 and 1.20±0.1mg of K, Mg, Ca, P, Mn, Cu, Fe and Zn, respectively. Antioxidant activity assay indicated that 100g haustorium was equivalent to 1918±173, 170±20.4, 72.8±14.7 and 860±116mg of Trolox as measured by CUPRAC, FRAP, DPPH and ABTS, respectively. Amino acid score indicated that methionine+cysteine (57.6%), phenylalanine+tyrosine (32.6%), leucine (45.7%) and isoleucine (68%) are found less in haustorium. Further studies needed in developing nutritionally balanced formulations using coconut haustorium, which will be useful for lactose intolerant children.
开展了一项研究，以确定椰子（椰属植物）吸器中的生化成分，吸器是椰子发芽过程中形成的一种海绵状组织。结果表明，100克干燥的椰子吸器含有1.05±0.2%的灰分、44.2±4.6%的可溶性糖、24.5±3.2%的淀粉、5.50±0.3%的蛋白质、1.99±0.9%的脂肪、5.72±0.4%的可溶性膳食纤维、20.3±1.9%的不溶性膳食纤维以及146±14.3毫克的酚类物质。矿物质分析表明，它分别含有145±8.6、104±9.6、33.9±8.2、30.9±1.9、9.45±2.1、0.292±0.1、2.53±0.2和1.20±0.1毫克的钾、镁、钙、磷、锰、铜、铁和锌。抗氧化活性测定表明，通过CUPRAC、FRAP、DPPH和ABTS法测定，100克吸器分别相当于1918±173、170±20.4、72.8±14.7和860±116毫克的Trolox。氨基酸评分表明，在吸器中蛋氨酸+半胱氨酸（57.6%）、苯丙氨酸+酪氨酸（32.6%）、亮氨酸（45.7%）和异亮氨酸（68%）的含量较低。在使用椰子吸器开发营养均衡配方方面还需要进一步研究，这对乳糖不耐受儿童将是有用的。
