高必需氨基酸营养米是指通过育种和栽培（喷施植物营养剂）技术,提高原粮的必需氨基酸含量,原粮经加工后,精米中组氨酸、苏氨酸、蛋氨酸、缬氨酸、苯丙氨酸、异亮氨酸、亮氨酸、赖氨酸等8种必需氨基酸总量达到 2 750 mg/100 g以上的大米。本课题组致力于高必需氨基酸营养米的生产,目前已研制出用于生产高必需氨基酸营养米的植物营养剂,并田间运用,喷施植物营养剂后的稻米其必需氨基酸含量显著提高。本文介绍了植物营养剂的基本概况和田间应用情况、高必需氨基酸营养米食品安全企业标准,并比较了不同水稻品种以及高必需氨基酸营养米与国内外几种优质米间的必需氨基酸含量,同时对高必需氨基酸营养米的开发前景进行展望。

High-essential amino acid nutritional rice refers to increasing the essential amino acid content of raw grains through breeding and cultivation（spraying plant nutrients） technology, after raw grains are processed, the total amount of eight essential amino acids in polished rice, including histidine, threonine, methionine, valine, phenylalanine, isoleucine, leucine, and lysine, is more than 2 750 mg/100 g. This research is devoted to produce nutritious rice with high essential amino acids. At present, we had developed a kind of plant nutrient which can be used to produce nutritious rice with high essential amino acids, and it has been applied in the field to increase the essential amino acid content of rice. This paper introduced the general situation and field application of plant nutrients, the enterprise standard of food safety of high essential amino acid rice, and compared the essential amino acid content among different rice varieties and between high essential amino acid nutritional rice and several high quality rice at home and abroad. At the same time, prospects the development of nutritional rice with high essential amino acids.
