Study on Low Temperature Pectinase on Clarification of Banana Juice Effect
Low temperature pectinase has the character of the mild,clarify the characteristics of good effect,less dosage. It had remarkable effect in fruit juice.In this paper,we got the following conclusion through single factor and orthogonal experiment:the optimum technological conditions were as follows,the dosage of the low temperature was 6 U/100 m L,the time was 60 min,the temperature was 20 ℃,the clarification of the banana juice can reach 95.7 %.
Objective To study the best extracting technology of Compound Taizishen Granule prescription.Methods The total polysaccharides and total saponins were determined by UV spectrophotometer.With the content of total polysaccharides and total saponins as comprehensive indexes,orthogonal test was applied to investigation of the water addition,extraction time,and extraction times for optimizing the best extracting technology.Results The best extracting technology was using 10 times the amount of water,extracting 3 times and 1.5 h per time.Conclusion The extraction technology is safe and effective,which can be used as extraction for Compound Taizishen Granule prescription.
