摘要: 研究经(0~2.5g/100m L)丙酸钙改性后的聚乙烯醇包装薄膜的各项包装性能和抗菌性能,结果发现,丙酸钙与聚乙烯醇薄膜相容性好,有良好的耐热性,丙酸钙的添加增加了薄膜的抗拉强度,降低了薄膜的断裂伸长率,影响了其光学性能,增加了薄膜的水蒸气透过系数、溶胀率和溶解率,提高了薄膜的热封温度。添加量为2.5g/100m L的丙酸钙改性薄膜对蜡样芽孢杆菌、大肠杆菌、米曲霉菌产生了一定的抑菌效果。经丙酸钙改性后的聚乙烯醇薄膜有良好的包装性能和一定的抑菌性,可以作为一种新型的食品内包装材料。Abstract: Different concentrations (02.5g/100 m L) calcium propionate were adding on polyvinyl alcohol (PVA) to prepare the calcium propionate modified polyvinyl alcohol packaging films.The results showed that calcium propionate had a good compatibility with the polyvinyl alcohol films, and the films had a good heat resistance.Calcium propionate increased the tensile strength, water vapor permeation coefficient, swelling ratio and dissolution rate of the films;reduced the breaking elongation of the films and affected the optical properties, the sealing temperature of the films.Concentration of 2.5g/100 m L calcium propionate modified film produced a certain inhibitory effect on Bacillus cereus, E. coli, Aspergillus oryzae. Calcium propionate modified polyvinyl alcohol films had a good packaging performance and some antibacterial properties, could be used as a novel food packaging material.
