摘要

使用塑料作为食品包装往往会产生问题,因为它很难分解;因此,它会污染环境。生物可降解塑料的发展是解决这一问题的另一种选择。壳聚糖是一种生物塑料,可作为包装材料,但其阻隔性能较差。以增塑剂、纳米壳聚糖和鳄梨种子淀粉为原料制备了一种生物可降解薄膜。采用UAE法合成纳米壳聚糖,振幅为50%,反应2 h,可制得0.7µm大小的纳米壳聚糖颗粒。采用浇铸法形成薄膜,并进行表征,包括官能团、厚度、颜色和抗氧化性测试。FTIR光谱表明,纳米壳聚糖与鳄梨种子淀粉发生了物理相互作用,酰胺羰基的波数从1646.60 cm-1转变为1549.99 cm-1。随着纳米壳聚糖用量的增加,膜的厚度为0.10 ~ 0.15 cm,颜色越深。抗氧化分析显示LC50值在150 ~ 250 ppm之间。所得到的薄膜对水蒸气的阻隔性能可以在室温下抑制草莓果实腐烂3-4天。

SYNTHESIS AND CHARACTERIZATION OF NANO CHITOSAN-AVOCADO SEED STARCH AS EDIBLE FILMS
The use of plastic as food packaging tends to cause problems because it is difficult to decompose; therefore, it can pollute the environment. The development of biodegradable plastics is an alternative to this problem. Chitosan, a bioplastic, can be used as a packaging material but has poor barrier properties. A biodegradable film was made from a mixture of plasticizer, nano chitosan, and avocado seed starch. Nanochitosan synthesis was carried out using the UAE method for 2 h at an amplitude of 50% to produce 0.7 µm sized particles. Films were formed using the casting method, and characterization was performed, which included functional group, thickness, color, and antioxidant tests. The FTIR spectrum showed that the interaction between nanochitosan and avocado seed starch occurred physically, marked by a shift in the wavenumber of the amide carbonyl group from 1646.60 cm-1 1549.99 cm-1. The film thickness was 0.10–0.15 cm with a darker color as the volume of nanochitosan used increased. Antioxidant analysis revealed that the LC50 value was between 150-250 ppm. The barrier properties of the resulting film against water vapor can inhibit strawberry fruit decay for 3–4 days at room temperature.
