摘要
以富士苹果为原料,研究了不同浓度的羧甲基纤维素钠(CMC-Na)、乳酸链球菌素、纳他霉素为原料的复合涂膜剂对鲜切苹果品质的调控作用。以蒸馏水浸泡作为空白对照,根据感官评价进行复合涂膜正交试验,得到复合涂膜剂最佳配方为:0.5%羧甲基纤维素钠+0.010%纳他霉素+0.015%乳酸链球菌素。经涂膜的鲜切苹果以PE袋真空包装、4℃贮藏15 d后,硬度值8.3 kg/cm2、L*值72.33、可溶性固形物含量12.9%,分别较对照提高20%、11.52%和12.17%。
With Fuji apple as raw material, the control function of different concentrations of carboxymethyl cellulose sodium（CMC-Na）, Nisin and Natamycin as compound coating agent on fresh-cut apple quality was studied,With distilled water to immerse fresh-cut apple as blank control. an orthogonal experiment of composite coating was carried out according to sensory evaluation,The best formula of the composite coating agent was as followed： carboxymethyl cellulose sodium 0.5%, Natamycin 0.010%, Nisin 0.015%.The coated fresh-cut apple was vaccum-packed in PE bag and stored at 4 ℃ for 15 days, the hardness was 8.3 kg/cm^2, L＊value was 72.33, soluble solids was 12.9%, which was increased by 20%, 11.52% and 12.17% respectively than control.
