摘  要:
【目的】以高酸海棠K9为原料,采用果胶酶制剂制取海棠果汁,获得最佳的工艺条件。【方法】试验设计了4个单因素:加酶量、酶解温度、pH值和酶解时间及相应的5个水平0.010%、0.015%、0.02%、0.025%、0.030%5个加酶量;30、35、40、45、50℃等5个温度参数;3、3.5、4.0、4.5、5.0等5个pH参数;60、90、120、150、180 min等5个时间参数,正交优化试验研究对海棠果出汁率的影响。【结果】在加酶量0.020%、酶解温度35℃、pH 4.0、酶解150 min的条件下,海棠果的出汁率最高。【结论】海棠果出汁率可达到92.18%,与未加果胶酶处理的空白实验73.92%相比,出汁率提高了18.26%。

摘  要:
Objective K9 gaosuan haitang was used as the experiment material. The influence factors of producing crabapples juice by pectinase were studied in this paper to obtain the optimum process conditions. MethodFour single factors were designed: enzyme content,hydrolysis temperature,pH and hydrolysis time of 5 appropriate levels: 0. 010%,0. 015%,0. 02%,0. 025% and 0. 030% 5 level enzyme contents; 30℃,35℃,40℃,45℃ and 50℃ 5 level hydrolysis temperatures; 3,3. 5,4. 0,4. 5,and 5. 0 5 levels pH; 60min,90min,120min,150min,and 180min 5 levels hydrolysis time. The liquefaction condition was optimized by mono-factor and orthogonal experiments. ResultThe results showed that the optimum reaction condition parameters was 0. 020% pectinase at 35 ℃ and pH 4. 0 for 150 min.ConclusionThe highest juice yield was attained to 92. 18%,which was increased by 18. 26 % compared with the blank test 73. 92 %.
