中文摘要:

      目的 探究模拟电商物流环境下纳米保鲜袋对香菇贮运品质的影响。方法 以香菇‘808’为实验材料, 通过测定失重率、色度、硬度、呼吸速率、可溶性固形物、相对电导率、可溶性蛋白、还原糖、抗坏血酸、总酚、类黄酮等一系列贮运品质指标, 考察不同包装(泡沫箱+普通PE保鲜袋、泡沫箱+纳米保鲜袋)对新鲜香菇的保鲜效果。结果 泡沫箱+纳米保鲜袋可有效延缓香菇贮运期间失重率、可溶性固形物、硬度和相对电导率的下降, 防止鲜香菇色泽劣变, 抑制香菇呼吸强度上升, 阻滞膜脂过氧化发生; 同时, 相比对照组, 纳米组能够有效保持可溶性蛋白、还原糖和抗坏血酸含量, 维持较高的总酚和类黄酮水平。贮运末期(第5 d), 泡沫箱+纳米保鲜袋处理的香菇失重率、呼吸强度、相对电导率分别为1.71%、232.20 mg/(kg·h)、28.68%, 均低于对照组; 而L* (64.60)、硬度(9558.32 g)、可溶性固形物(3.19%)、可溶性蛋白(1.25 mg/g)、还原糖(0.77 mg/g)、总酚(16.51 mg/100 g)、类黄酮(53.61 mg/100 g)均高于对照组。结论 泡沫箱+纳米保鲜袋能够有效抑制模拟电商物流过程中香菇的品质劣变, 降低营养价值的损失, 提高贮运品质, 延长货架期。本研究可为模拟电商物流包装新鲜香菇的应用提供技术支持。

英文摘要:

      Objective To explore the effects of nano fresh-keeping bags on the storage and transportation quality of fresh Lentinula edodes in a simulated E-commerce logistics environment. Methods With Lentinula edodes ‘808’ as the experimental material in this study. A series of storage and transportation quality indexes such as weight loss rate, color, hardness, respiration rate, soluble solids, relative conductivity, soluble protein, reducing sugar, ascorbic acid, total phenol, and flavonoids were measured to investigate the fresh-keeping effect of different packaging (foam box and ordinary PE fresh-keeping bag, foam box and nano fresh-keeping bag) on fresh Lentinula edodes. Results The results showed that the foam box and nano-preservative bag could effectively delay the decrease of weight loss rate, total soluble solid, hardness, and relative conductivity of Lentinula edodes during storage and transportation, prevent the color deterioration of fresh Lentinula edodes, inhibit the increase of respiration intensity of Lentinula edodes, and block the occurrence of membrane lipid peroxidation. At the same time, compared with the control group, the nano-group could effectively maintain the content of soluble protein, reduce sugar, and ascorbic acid, and maintain a higher level of total phenols and flavonoids. At the end of storage and transportation (5th day), the weight loss rate, respiratory intensity, and relative conductivity of Lentinula edodes in the foam box and nano fresh-keeping bag were 1.71%, 232.20 mg/(kg·h), and 28.68%, respectively, which were lower than those of the control group. The L* (64.6), hardness (9558.32 g), soluble solids (3.19 mg/g), soluble protein (1.25 mg/g), reducing sugar (0.77 mg/g), total phenols (16.51 mg/100 g), and flavonoids (53.61 mg/100 g) were higher than the control group. Conclusion The foam box and nano fresh-keeping bag can effectively inhibit the quality deterioration of Lentinula edodes during simulated E-commerce logistics, reduce the loss of nutritional value, improve the quality of storage and transportation, and extend the shelf life. This study can provide technical support for applying simulated E-commerce logistics packaging of fresh Lentinula edodes.
