不同包装材料对草莓贮藏品质和保鲜期的影响

Effect of different packaging materials on the quality and shelf life of strawberry

摘要: 在4℃贮藏条件下,采用不同的塑料包装材料(LDPE、HDPE和OPP膜)对草莓进行保鲜包装,测定不同贮藏时间下草莓的失重率、好果率、VC含量、果实硬度和可溶性固形物。结果表明:塑料包装膜能明显抑制草莓变质;具有较低透气率的HDPE薄膜保鲜效果最好,其次是OPP膜,再次是LDPE膜。

Abstract: In this paper, different plastic packaging materials (LDPE, HDPE and OPP film) were used for strawberry preservation at 4℃. Weight loss, fruit rate, VCcontent, fruit firmness and total soluble solids IT were measured under different storage time about strawberry. The results showed that plastic packaging films could inhibit the metamorphism of strawberries significantly. HDPE film preservation effect of low permeability was best, secondly OPP film, finally LDPE film.
