阅读说明：本技术 一种基于香菇柄中性多糖的果汁抑菌剂 (Fruit juice bacteriostatic agent based on neutral polysaccharide of lentinus edodes stems ) 是由 邓红 刘靓 孟永宏 梁佳蕊 田丹 郭玉蓉 于 2021-01-25 设计创作，主要内容包括：本发明公开了一种基于香菇柄中性多糖的果汁抑菌剂,其由香菇柄中性多糖与苹果幼果多酚按质量比为1:1～4混合而成。本发明利用香菇柄中性多糖复配苹果幼果多酚制备天然果汁抑菌剂,香菇柄中性多糖和苹果幼果多酚均为天然物质,不会对人体造成危害,其中香菇柄中性多糖具有抗菌、抗氧化、抗癌等作用,对大肠杆菌、金黄色葡萄球菌及枯草芽孢杆菌等具有明显的抑制作用,苹果幼果多酚能有效抑制微生物活动,两者复配在保留原果汁天然风味基础上能较彻底、更有效的抑制果汁中微生物生长,不仅可以有效抑制大肠杆菌、金黄色葡萄球菌和沙门氏菌生长,还可以高效抑制脂环酸芽孢杆菌生长,防止由微生物引起的腐败,延长果汁的保藏期。(The invention discloses a fruit juice bacteriostatic agent based on neutral lentinus edodes stem polysaccharide, which is prepared by mixing the neutral lentinus edodes stem polysaccharide and young apple polyphenol in a mass ratio of 1: 1-4. The natural fruit juice bacteriostatic agent is prepared by compounding the lentinus edodes stem neutral polysaccharide with the apple young fruit polyphenol, wherein the lentinus edodes stem neutral polysaccharide and the apple young fruit polyphenol are natural substances and do not cause harm to human bodies, the lentinus edodes stem neutral polysaccharide has the effects of resisting bacteria, oxidation, cancer and the like, and has an obvious inhibiting effect on escherichia coli, staphylococcus aureus, bacillus subtilis and the like, the apple young fruit polyphenol can effectively inhibit the activity of microorganisms, and the two are compounded on the basis of retaining the natural flavor of the original fruit juice, so that the microbial growth in the fruit juice can be completely and effectively inhibited, the growth of escherichia coli, staphylococcus aureus and salmonella can be effectively inhibited, the growth of alicyclobacillus can be effectively inhibited, the spoilage caused by microorganisms is prevented, and the preservation period of the fruit juice is prolonged.)
