Amaranth grain is reputed to have a high nutritional value, and as a plant, be tolerant to adverse weather conditions. This suggests that grain amaranth could be useful in tackling malnutrition and the growing burden of cardiometabolic diseases. However, there is insufficient knowledge at present about how the nutrient composition and digestibility of amaranth grain varies with growing environment, crop genotype, and post-harvest processing. We investigated the effect of the source and processing of amaranth grains on the digestibility of protein and lipid present in the grains. There was variation in the composition and digestibility of raw grains from different sources, indicating a role of genotype and/or growing environment which warrants further investigation. The greatest differences in digestibility were measured between the different processing techniques. This indicates that efforts to increase the cultivation and consumption of grain amaranth need to be supported by education about effective processing and preparation techniques.

菜籽被认为具有很高的营养价值，并且作为一种植物，可以耐受恶劣的天气条件。这表明grain菜籽可能有助于解决营养不良和心脏代谢疾病日益严重的负担。但是，目前关于about菜籽粒的营养成分和消化率如何随生长环境，农作物基因型和收获后加工的变化而知之甚少。我们调查了of菜籽粒的来源和加工过程对籽粒中蛋白质和脂质消化率的影响。来自不同来源的粗粮的组成和消化率存在差异，表明基因型和/或生长环境的作用值得进一步研究。在不同的加工技术之间，消化率差异最大。这表明需要通过有关有效加工和制备技术的教育来支持增加籽粒cultivation菜的种植和消费的努力。
