中文摘要: |
采用冷处理法、复合酶法和明胶法对余甘子果汁进行澄清处理,分别考察其对余甘子果汁品质的影响。结果表明:冷处理法最温和,对Vc 含量和SOD 活性基本无影响,但澄清效果差,澄清处理12 h,褐变度降低12%,透光率升高3%;复合酶法澄清效果显著,而且对Vc 含量和SOD 活性影响小,酶解3 h,褐变度降低44%,透光率升高10%,Vc 含量损失4%,SOD 活性损失5%;明胶法能取得较好的澄清效果,控制澄清时间,该法对Vc 和SOD 活性的影响也相对较小,明胶法澄清果汁4 h,褐变度降低56%,透光率升高13%,此时Vc含量损失8%,SOD 活性损失12%。 |

Three clarifying methods of cold treatment method, compound enzyme method and gelatin fining were tested to clarify
emblica fruit juice. The results showed as follows: Cold treatment method had little influence on Vc content and SOD activity, but clarification effect was poor, with clarifying treatment 12 h, browning degree was reduced by 12% and light transmittance rose 3%;Clarification effect of compound enzyme was remarkable, and compound enzyme method had much less effect on Vc content and SOD activity, with clarifying treatment 3 h, browning degree was reduced by 44%, light transmittance rose 10%, loss of Vc content was 4% and loss of SOD activity was 5%; Gelatin fining achieved good effect, with clarifying treatment 4 h, browning degree was reduced by 56%,light transmittance rose 13%, loss of Vc content was 8% and loss of SOD activity was 12%. |
