Abstract
The purpose was to study the influence of four kinds of clarifying agent of longan wine clarification effect and stability. Based on the single factor experiment, the orthogonal experiment design was used to establish the optimum conditions for use:chitosan dosage 0.6 g/L,quiet time 15 days,temperature 20 ℃,gelatin dosage 0.2 g/L,quiet time 15 days,temperature 15 ℃,egg white powder dosage 0.4 g/L,quiet time15 days,temperature 15 ℃,bentonite dosage 0.9 g/L,quiet time 15 days,temperature 25 ℃. Further verification test results showed that when the four kinds of clarifying agents were used alone, it showed a good effect of clarification, in which the effect of bentonite was the best, and the light transmittance of the liquor was as high as 97.03%. After the clarification of chitosan and bentonite,the longan wine had a good thermal stability.
