Study on the processing technique of bright kiwi fruit juice
The factors effect on photic degree a fter adding chitosan to kiwifruit ju ice such as the degree of deacetylation of chitosan,pH of kiwifruit juice,a nd keeping time on 47℃of juice after adding chitosan to fru it juice were investigated.Based on these experiment and orthogonal experiment design result,we fo und out the best condition of clarifing natural kiwifruit juice.The best condition is chitosan of 80%degree of deacetylation,0.4g /L adding admeasure of ch itosan,40℃keeping 40minutes and 30minutes centrifuge time.Signal factors that af fect the result of clarifing kiwifru it juice are the degree of deacetylation,tim e of keeping constant temperature af ter adding chitosan and centrifuge t ime.
