摘要
通过单因素实验找出打卡类产品发霉的原因,并筛选出防霉效果明显的纳他霉素作为生产用药剂,通过正交实验找出最佳配比浓度适用于生产。即产品在包装前,使用0. 8%浓度纳他霉素水溶液,浸泡1min完全可以有效控制打卡类产品的发霉问题。
Through single factor experiment,the cause of mildew in punch card products was found out,and the natamycin which had obvious anti-mildew effect was selected as the production agent.Through orthogonal experiment,the optimum proportion concentration was found,and it was suitable for production. Before the packaging,the natamycin aqueous solution of 0. 8% concentration was used,and the product was immersed for 1 min,and the mildew problem of the punch card products was completely and effectively controlled.
