以天然抗菌物质苦瓜多糖和大豆分离蛋白制成涂膜保鲜剂是一项新的研究热点.本研究以鲜切马铃薯为实验材料,采用苦瓜多糖和不同浓度的大豆分离蛋白制成的复合涂膜液处理鲜切马铃薯,贮藏过程中对感官评价、失重率、褐变度、可溶性固形物含量、丙二醛含量、还原糖含量、总酚含量进行测定,比较不同浓度的苦瓜多糖复合液对鲜切马铃薯的保鲜效果.结果表明,浓度为10 mg/mL苦瓜多糖和4%大豆分离蛋白复合涂膜液对鲜切马铃薯保鲜效果最佳.
Preservation of fresh cut potato by Momordica polysaccharide/soybean protein isolate composite membrane
The use of natural antibacterial substances such as bitter gourd polysaccharides and soy protein i-solate solutions as a composite to produce coating preservatives is a new research hotspot.Using fresh cut potatoes as experimental materials,a composite coating solution made of bitter gourd polysaccharides and different concentrations of soy protein isolate was used to treat fresh cut potatoes.During storage,sensory evaluation,weight loss rate,browning degree,soluble solid content,malondialdehyde content,reducing sug-ar content,and total phenolic content were measured to compare the preservation effect of different concen-trations of bitter gourd polysaccharide composite solution on fresh cut potatoes.The results showed that the composite coating solution of 10 mg/mL bitter gourd polysaccharide and 4%soy protein isolate had the best preservation effect on fresh cut potatoes.
