壳聚糖对小苹果汁澄清效果的影响

Effect of Chitosan on the Clarification of Small Apple Juice

以黑龙江省地产小苹果K9为试材,研究了壳聚糖不同浓度添加量、澄清时间、澄清温度对小苹果汁透光率和色值的影响。结果表明:澄清工艺的最优组合为A3B2C2,即添加量0.4g/L,澄清温度50℃,澄清时间180min,透光率最高可达95.47%。

With a local produced small apple K9 as materials,different concentration,time and temperature of chitoson on the effect of clarification of small apple juice were studied.The results showed that the best combination processing technique were A3B2C2,the amount of chitoson was 0.4 g/L,temperature was 50℃,time was 180 min,under this condition,the transmittance rate reached 95.47%.
