【摘要】 通过测定“台农”,“京6”,“55-2”和“红冬”四种甘薯品种所提取蛋白粉各组分(粗蛋白、粗纤维、粗脂肪、水分、灰分、总糖、金属元素)的含量、分析氨基酸组成、蛋白构成成分和色泽等项指标的差异,对四种甘薯蛋白粉品质进行了比较研究。结果表明,甘薯“55-2”所提取的蛋白粉纯度最高,其蛋白含量达到86.89%,且蛋白粉色泽好,金属元素含量少。更多还原

【Abstract】 This study compared the quality of the protein powders obtained from 4 typical types of sweet potato varieties (TaiNong, Jing 6, 55-2, and HongDong), by measuring the variation of the composition of the protein (incl. crude protein, crude fiber, crude fat, moisture, ash, total sugar and metal amount), analyzing their amino acids composition, protein constituent and different colors of the powder. The results shown that the protein powder made from ″55-2″ had the highest purity, which was 86.89%, and it had a good color and low amount of metal content.更多还原
