Abstract New plant-based milk protein substitutes that do not exhibit immune-mediated adverse effects are in high demand. In-vitro digestibility (oral, gastric and duodenal) of rice was investigated at flowery, milky, dough and mature stages using SDS-PAGE and band densitometry. Possible allergenic proteins found were 13–14, 22–23, 37–39, and 52 kDa. Protein content in young rice at flowery-to-milky stage (9.19–11.48%) was higher than rice bran (8.90%). Possible allergens of young rice rapidly decreased and completely disappeared after digestion. Digestibility of dough-to-mature stage was much slower especially for colored rice. Proteins at 13–14, 52 kDa and 13–14, 37–39 kDa were indigestible in the mature stage of PT1 and RB respectively. High protein content and low allergic potential of young rice supported its possible use as a new plant-based protein alternative.

年轻大米蛋白作为低过敏性植物蛋白的新来源

摘要 对不表现出免疫介导的不良反应的新型植物性乳蛋白替代品的需求量很大。使用 SDS-PAGE 和条带密度测定法研究了大米在开花、乳状、面团和成熟阶段的体外消化率(口服、胃和十二指肠)。发现的可能的过敏蛋白为 13-14、22-23、37-39 和 52 kDa。花至乳期幼稻蛋白质含量(9.19-11.48%)高于米糠(8.90%)。幼稻可能过敏原迅速减少,消化后完全消失。面团到成熟阶段的消化率要慢得多,尤其是对于有色大米。13-14、52 kDa 和 13-14、37-39 kDa 的蛋白质分别在 PT1 和 RB 的成熟阶段难以消化。
