中文摘要: 研究壳聚糖的用量、时间、温度和pH对新梨7号果汁澄清效果的影响，结果表明， pH值对梨汁亮度有极显著影响，壳聚糖用量对梨汁的亮度影响显著，温度和时间对梨汁的亮度影响不显著；四个因素对还原糖含量的影响均
不显著。正交实验澄清的最佳亮度条件为壳聚糖用量0.4 g/L、温度 55 ℃、pH 值 3.5 和时间 60 min。
Abstract:Effects of chitosan concentration， time，temperature and pH on Xinli No.7 clarified juice were studied in the paper. Results indicated that pH value and chitosan concentration affected the lightness of juice remarkablely. And time and temperatre showed no prominent effect. The four factors were indistinctively on reducing sugar content. The optimum conditions with chitosan to clarification of Xinli No.7 Juice by orthogonal experiment were chitosan concentration 0.4 g/L，55 ℃，pH3.5 and 60 min.
