摘要
选取壳聚糖作为澄清剂制作一批澄清黄秋葵汁并将其分别放置于4℃、室温(20℃)和37℃避光储藏。在不同储藏时间分别随机取样,测定秋葵汁中总酚含量、蛋白含量、褐变指数、悬浮稳定性和透光率。结果表明,在不同温度下,秋葵汁在储藏过程中透光率、悬浮稳定性、可溶性蛋白、总酚含量都随着时间的延长逐渐降低,而褐变指数随着时间的延长逐渐升高。随着储藏温度升高,悬浮稳定性和可溶性蛋白降低,而褐变指数和总酚含量升高。
With chitosan as clarificant, a batch of clarified okra juice was produced and stored in a dark place at 4,37℃ and room temperature ( 20℃ ), respectively. The total phenol content, soluble protein content, browning index, suspension stability and light transmittance of okra juice were measured by random sampling at different storage times. The results showed that the total phenol content, soluble protein content, suspension stability and light transmittance decreased, while browning index gradually increased during storage. With the increase of storage temperature, suspension stability and soluble protein content decreased, while total phenol content and browning index increased during storage.
