[Method] Concentrated apple juice was used as the raw material in this experiment, apple clear juice beverage was produced through dilution, blending, color protection, sterilization and other key processes. By using orthogonal test, the best formula of the apple clear juice beverage was determined, and then the color protection effects of three color protection agents Cys, NaHSO3 and Vc on the apple clear juice beverage were compared. [ Result] The best formula of the apple clear juice beverage was composed of 0.15% citric acid, 0.20% sodium citrate, 0.06% tannic acid, 6% white sugar and 16% concentrated apple juice. Besides, there was a big difference among the three kinds of color protection agents （ Cys, NaHSO3 and Vc ） in the color protection effects on the apple clear juice beverage. Considering the quality safety of the product, 0.60% Vc was chosen as the best color protection a.clent. I- Conclusionl The research could provide theoretical references for using concentrated aDDle juice to produce aDDle clear iuice beveraae.展开更多
