摘　　要：为探究改性类黑精和刺梨渣提取物添加量对淀粉-明胶复合保鲜膜性能的影响及其对核桃的保鲜效果,以淀粉-明胶为基质,添加类黑精和刺梨渣提取物,筛选最佳成膜配方,并应用于核桃保鲜。结果表明当类黑精和刺梨渣提取物添加量为0.75%和0.4%时,成膜性能最佳;复合膜抗氧化能力与类黑精和提取物添加量成正比;复合膜有效保鲜核桃。因此,添加改性类黑精和刺梨渣提取物的复合保鲜膜成膜性良好,有利于延长坚果类食品货架期。The complex films were constructed based on starch-gelatin added with different amount of modified black garlic melanoidin and Rosa roxbunghii pomace extract.To investigate the preservation effect of such edible film,the storage quality of walnuts packed with novel complex film and traditional aluminum foil film were compared.The results showed that the complex film containing 0.75%mela noidin and 0.4%pomace extract displayed the best performance in oxygen barrier rate and mechanical ability like fracture tensile rate and tensile strength,making it suitable for subsequent preservation.The DPPH and ABTS scavenging activity of the films increased with t he adding of melanoidin and residue extract.The study proved that the novel complex film was beneficial for prolonging the shelf life of walnuts.
