  • 摘要: 【目的】 研究板栗壳色素(CSP)添加量对海藻酸钠/羧甲基纤维素(SA/CMC)包装膜理化特性、功能特性及草莓保鲜效果的影响。【方法】 以CSP、SA、CMC为基质,采用流延干燥法制备活性包装膜,测定其理化特性、光学特性、抗氧化活性相关指标,对其结构进行表征,并将其应用于草莓保鲜。【结果】 负载不同质量分数CSP包装膜的理化特性、光学特性和抗氧化活性存在显著差异。CSP与膜基质间相容性良好,它们之间主要通过分子间氢键和范德华力形成紧密的三维网络结构,从而提高膜的厚度、不透明度、拉伸强度和水蒸气透过率,并改善CO2/O2透过比。其中,添加3% CSP的包装膜(SA/CMC/CSP-3)综合性能最佳,其拉伸强度为32.79 MPa,断裂伸长率为31.40%,O2透过率为18.79×10-7 cm3/(m2·24 h·Pa),CO2透过率为1.51×10-5 cm3/(m2·24 h·Pa),CO2/O2透过比为8.04∶1,更适合用于高呼吸强度的果蔬包装。此外,CSP的引入显著增强了膜的紫外线阻隔性能和抗氧化能力,SA/CMC/CSP-3和SA/CMC/CSP-5的DPPH自由基清除率分别为90.17%和93.67%,ABTS+自由基清除率分别为81.40%和98.58%。与SA/CMC包装的草莓相比,SA/CMC/CSP-3包装的草莓在贮藏第7 d的失重率和腐烂率分别降低了2.0%和17.0%。【结论】 SA/CMC/CSP-3包装膜具有较好的理化特性、光学特性和抗氧化活性,能有效延缓草莓水分散失和腐败变质,表现出良好的保鲜效果。
    Abstract: 【Objective】 To investigate the effects of chestnut shell pigment (CSP) content on the physicochemical and functional properties of sodium alginate/carboxymethyl cellulose (SA/CMC) films and on their strawberry preservation performance.【Methods】 Active packaging films were prepared via solution casting using CSP, SA, and CMC as the matrix. Their physicochemical properties, optical properties, antioxidant activity, and structure were characterized, and their preservation performance on strawberries was evaluated.【Results】 The films loaded with different mass fractions of CSP exhibited significant differences in their physicochemical properties, optical properties, and antioxidant activity. CSP exhibited good compatibility with the film matrix, forming a compact three-dimensional network structure mainly through intermolecular hydrogen bonding and van der Waals forces, which in turn increased the film thickness, opacity, tensile strength, and water vapor transmission rate, and improved the CO2/O2 transmission ratio. Among them, the film containing 3% CSP(SA/CMC/CSP-3) exhibited the best overall performance, with a tensile strength of 32.79 MPa, an elongation at break of 31.40%, an oxygen transmission rate of 18.79×10-7 cm3/(m2·24 h·Pa), a carbon dioxide transmission rate of 1.51×10-5 cm3/(m2·24 h·Pa), and a CO2/O2 transmission ratio of 8.04∶1, making it more suitable for packaging fruits and vegetables with high respiration rates. In addition, the incorporation of CSP significantly enhanced the UV-blocking ability and antioxidant capacity of the films. The DPPH radical scavenging rates of SA/CMC/CSP-3 and SA/CMC/CSP-5 were 90.17% and 93.67%, respectively, and the ABTS+ radical scavenging rates were 81.40% and 98.58%, respectively. Compared with strawberries packaged with the SA/CMC film, those packaged with SA/CMC/CSP-3 showed reductions in weight loss and decay rate of 2.0% and 17.0%, respectively, on the 7th day of storage.【Conclusion】 The SA/CMC/CSP-3 film exhibited good physicochemical and optical properties and antioxidant activity, effectively delaying moisture loss and spoilage in strawberries and demonstrating a good preservation effect.

摘要: 【目的】 研究板栗壳色素(CSP)添加量对海藻酸钠/羧甲基纤维素(SA/CMC)包装膜理化特性、功能特性及草莓保鲜效果的影响。【方法】 以CSP、SA、CMC为基质,采用流延干燥法制备活性包装膜,测定其理化特性、光学特性、抗氧化活性相关指标,对其结构进行表征,并将其应用于草莓保鲜。【结果】 负载不同质量分数CSP包装膜的理化特性、光学特性和抗氧化活性存在显著差异。CSP与膜基质间相容性良好,它们之间主要通过分子间氢键和范德华力形成紧密的三维网络结构,从而提高膜的厚度、不透明度、拉伸强度和水蒸气透过率,并改善CO2/O2透过比。其中,添加3% CSP的包装膜(SA/CMC/CSP-3)综合性能最佳,其拉伸强度为32.79 MPa,断裂伸长率为31.40%,O2透过率为18.79×10-7 cm3/(m2·24 h·Pa),CO2透过率为1.51×10-5 cm3/(m2·24 h·Pa),CO2/O2透过比为8.04∶1,更适合用于高呼吸强度的果蔬包装。此外,CSP的引入显著增强了膜的紫外线阻隔性能和抗氧化能力,SA/CMC/CSP-3和SA/CMC/CSP-5的DPPH自由基清除率分别为90.17%和93.67%,ABTS+自由基清除率分别为81.40%和98.58%。与SA/CMC包装的草莓相比,SA/CMC/CSP-3包装的草莓在贮藏第7 d的失重率和腐烂率分别降低了2.0%和17.0%。【结论】 SA/CMC/CSP-3包装膜具有较好的理化特性、光学特性和抗氧化活性,能有效延缓草莓水分散失和腐败变质,表现出良好的保鲜效果。
