Abstract:Using the Ralls as raw materials, dry cider was produced by pulp beating, color-protecting, enzyme treating, composition adjusting, fermenting and clarifying. Through the single factor experiments, the best conditions of color-protecting and clarifying were the addition of 0.1% citric acid and 0.04% vitamin C after beating, the chitosan addition of 0.25% to apple wine and the treatment time of 24 hours.
