摘  要:
根据天然沸石上可以吸附阳离子,壳聚糖在酸性溶液中带有正电荷的特性,将120目天然沸石与90%脱乙酰度壳聚糖的0.5%醋酸溶液按1:1.2质量比混合制成制成固体澄清剂,用其处理陈醋。最佳工艺条件是:陈醋中澄清剂添加量1.5%、作用时间5min、作用温度为室温;得到了黑紫色、透明的高档陈醋,且放置6个月无沉淀。产生的滤泥作为农田肥料和动物饲料添加剂,对环境无污染。

摘  要:
According the properties of natural zeolite and chitosan, a solid adsorbent was made from natural zeolite and chitosan. 120mm natural zeolite was added in chitosan slurry of 90% the degree of deacetylation to prepare adsorbent which mass ratio is 1:1.2. The absorbent can be used to treat aged vinegar. The optimal operation conditions are: the absorbent amount of addition 1.5%, mixing time 5min, at room temperature. After treated by the adsorbent, the vinegar was easily filtered and had a high- quality with amber color and transparence. The vinegar product could be stored for 6 months without any sediment problem. The filtrate slurry can be used for fertilizer and feed additive without environmental pollution
