摘要
研究了壳聚糖对番石榴汁澄清效果。该试验结果表明，壳聚糖用量为0．04-0．1g／L，澄清时间为60-100min。果汁温度为50-70℃的条件下，番石榴汁澄清处理的透光率可达90％以上，且澄清果汁中可溶性固形物、Vc含量保持不变。通过正交试验，得出壳聚糖对番石榴汁澄清处理的最佳工艺参数：壳聚糖的最适用量为0．06g／L，最佳澄清时间60min，最适温度为60℃。
The clarification of guava juice by chitosan was studied. The result showed that the suitable chaitosan dosage, temperature, pH and clarifying time were 0.04-0.1g/L, 50-70℃, 3.70, and 60-100 min, respectively, under which the transmittance of the juice was above 90% with the contents of soluble substances and Vitc content being constant. The best chaitosan dosage, temperature, and clarifying time were further optimized by orthogonal test to be 0.06 g/L,60℃ and 60 min, respectively.
