Abstract：
Waste from non-degradable packaging materials poses a serious environmental risk and has led to interest in developing sustainable bio-based packaging materials. Sustainable packaging materials have been made from diverse naturally derived materials such as bamboo, sugarcane, and corn starch. In this study, we made a sustainable packaging film using chitosan extracted from the biomass of yellow mealworm (Tenebrio molitor) shell waste. The extracted chitosan was used to create films, cross-linked with citric acid (CA) and with the addition of glycerol to impart flexibility, using the solvent casting method. The successful cross-linking was evaluated using Fourier-Transform Infrared (FTIR) analysis. The CA cross-linked mealworm chitosan (CAMC) films exhibited improved water resistance with moisture content reduced from 19.9 to 14.5%. Improved barrier properties were also noted, with a 28.7% and 10.2% decrease in vapor permeability and vapor transmission rate, respectively. Bananas were selected for food preservation, and significant changes were observed over a duration of 10 days. Compared to the control sample, bananas packaged in CAMC pouches exhibited a lesser loss in weight because of excellent barrier properties against water vapor. Moreover, the quality and texture of bananas packaged in CAMC pouch remained intact over the duration of the experiment. This indicates that adding citric acid and glycerol to the chitosan structure holds promise for effective food wrapping and contributes to the enhancement of banana shelf life. Through this study, we concluded that chitosan film derived from mealworm biomass has potential as a valuable resource for sustainable packaging solutions, promoting the adoption of environmentally friendly practices in the food industry.
摘要：
来自不可降解包装材料的废物构成了严重的环境风险，并引起了人们对开发可持续生物基包装材料的兴趣。可持续包装材料由多种天然衍生材料制成，如竹子，甘蔗,和玉米淀粉.在这项研究中,我们使用从黄粉虫（黄粉虫）壳废物的生物质中提取的壳聚糖制成了可持续的包装膜。提取的壳聚糖用于制造薄膜，与柠檬酸（CA）交联并添加甘油以赋予柔韧性，采用溶剂流延法。使用傅里叶变换红外(FTIR)分析评价成功的交联。CA交联的粉虫壳聚糖（CAMC）膜表现出改善的耐水性，水分含量从19.9％降低到14.5％。还注意到改进的阻隔性能，蒸汽渗透率和蒸汽透过率分别下降28.7%和10.2%，分别。选择香蕉用于食品保存，并且在10天的持续时间内观察到显着变化。与对照样品相比，包装在CAMC袋中的香蕉由于对水蒸气具有优异的阻隔性能而表现出较小的重量损失。此外，包装在CAMC袋中的香蕉的质量和质地在实验期间保持完整。这表明向壳聚糖结构中添加柠檬酸和甘油有望有效包装食品，并有助于提高香蕉的保质期。通过这项研究,我们得出结论，源自粉虫生物质的壳聚糖膜具有作为可持续包装解决方案的宝贵资源的潜力，促进食品行业采用环保做法。
