摘要
[目的]通过溶液流延法开发一种基于大豆分离蛋白(SPI)、浓缩乳清蛋白(WPC)与牛蒡多糖(Arctium lappa L.polysaccharide,ALP)的活性食用薄膜。[方法]通过对复合膜的表面形貌、拉伸强度(TS)、断裂伸长率(EAB)、水溶性(WS)、水分含量(MC)和水蒸气透过率(WVP)以及透光率进行表征,系统考察不同ALP配比对复合膜性能的影响,筛选出最优配比的复合膜,并进一步分析其在羊肚菌保鲜中的应用效果。[结果]当SPI/WPC与ALP质量比为1.0∶0.2时,SPI/WPC/ALP薄膜的机械性能、阻隔性以及透光性能显著提高(P<0.05)。此外,在羊肚菌保鲜试验中,SPI/WPC/ALP薄膜减少了羊肚菌酚类物质流失,降低了酪氨酸含量与丙二醛(MDA)含量,有效缓解了褐变程度,提升了羊肚菌品质,延长了保鲜时间。[结论]SPI/WPC/ALP复合膜可能是一种很有前途的环保包装材料,可应用于食用菌保鲜。
[Objective]To develop an active edible film based on soy protein isolate(SPI),whey protein concentrate(WPC),and Arctium lappa L.polysaccharide(ALP)by using the casting method.[Methods]This study characterizes the surface morphology,tensile strength(TS),elongation at break(EAB),water solubility(WS),moisture content(MC),water vapor permeability(WVP),and light transmittance of the composite film.It also systematically investigates the impact of different ALP proportions on film properties.The optimal ratio for the film is identified,and its performance in Morchella preservation is evaluated.[Results]When the mass ratio of SPI/WPC to ALP is 1.0∶0.2,the SPI/WPC/ALP film shows significantly enhanced mechanical properties,barrier performance,and light transmittance(P<0.05).In the Morchella preservation experiment,this film effectively reduces the loss of phenolic substances,decreases tyrosine and malondialdehyde(MDA)levels,mitigates browning,and improves the quality and shelf life of Morchella.[Conclusion]The SPI/WPC/ALP composite film is a promising eco-friendly packaging material with potential applications in edible fungus preservation.
