Abstract

The chemical composition, content of antinutritional factors, and the in vitro protein digestibility of grains of the pseudo-cereal Amaranthus were analyzed. The plants were grown in Brazil (without fertilizer), Puerto Rico (100 kg N/ha), and California (200 kg N/ha). The seed analysis gave the following values (%DM): 14.4 - 16.9 protein (N X 6.25), 4.8 - 6.8 fat, 2.5 - 3.9 ash, and 2.3 - 2.9 crude fiber. The trypsin inhibitors, phenolics and saponine contents were low, and the phytohemagglutinin activity, fairly low. The in vitro protein digestibility was 61 - 76%. Digestibility was not correlated to the analyzed proximal composition nor to the antinutritional factors. The grain composition indicates a food value equivalent to that of conventional food grains.

摘要

对伪谷物苋属植物种子的化学成分、抗营养因子含量及体外蛋白质消化率进行了分析。这些植物分别种植于巴西（不施肥）、波多黎各（100千克氮/公顷）和加利福尼亚（200千克氮/公顷）。种子分析得出以下含量（占干物质百分比）：蛋白质14.4 - 16.9%（氮×6.25）、脂肪4.8 - 6.8%、灰分2.5 - 3.9%、粗纤维2.3 - 2.9%。胰蛋白酶抑制剂、酚类和皂苷含量较低，植物血凝素活性也相当低。体外蛋白质消化率为61 - 76%。消化率与分析得出的常规成分及抗营养因子均无相关性。种子成分表明其营养价值与传统粮食相当。
