摘要:

研究壳聚糖添加量对大豆分离蛋白复合材料机械性能、阻隔性能、颜色和结构的影响,以提高大豆分离蛋白可食性包装材料的性能。结果表明:当壳聚糖与大豆分离蛋白的质量比为1∶1时,复合材料的综合性能最佳,其抗拉强度提高,断裂伸展率、水蒸气透过率和氧气透过率降低,颜色略微发黄。红外光谱分析结果显示提高复合材料的机械性能和阻隔能力的主要原因可能是大豆分离蛋白与壳聚糖之间形成醚键或C-N键。

Abstract:

The effect of chitosan addition on the color, mechanical properties and barrier properties of soybean protein
isolate (SPI) composite packaging materials was evaluated. The composite packaging materials showed the best properties
when the ratio of chitosan to SPI was 1:1. The tensile strength of the composite packaging materials increased, while the
elongation at break, water vapor permeability and oxygen permeability decreased. Moreover, the color turned slightly yellow
within the range of consumer acceptance. The formation of ether linkage or C-N bond between SPI and chitosan could be
the major reasons for the improvement of these properties.

Key words: soybean protein isolate, chitosan, packaging materials, barrier properties, infrared spectroscopy
