利用吸附树脂处理苹果酒

提出并研究了吸附树脂澄清苹果酒的新工艺 ,选出了合适的吸附树脂及其再生方法。结果表明 ,在 5种树脂中A 4 3和H 5的效果较好 ,处理后苹果酒的脱色率达到 2 8% ;树脂用 90℃ ,质量分数 0 5 %NaOH溶液再生可恢复原有吸附水平 ;吸附树脂对苹果酒中没食子酸存在定量吸附关系 ,可用弗伦特利希 (Freundlich)方程式描述 ;吸附树脂可以有效去除苹果酒中的可溶性蛋白质和酚类物质。

Study on the Application of Adsorbent Resin in the Clarification of Cider

This study suggests the new technology about clarification of cider with adsorptive resins. The proper adsorptive resins and the regeneration methods were selected. The results showed that A-43 and H-5 resins have good clarified effect, their decolorized rate of cider are up to 28%;regenerated the resin by 0.5% NaOH in 90 ℃ can resume their adsorptive ability ; the resins have quantificational adsorptive relation to gallic acid , and the adsorptive relation can be show by Freundlich equation; the resins can effectively remove the soluble protein and phenol compound in cider.
