本试验用七八成熟的草莓为材料，对草莓果实采用不同浓度的壳聚糖处理涂膜，并分别在4℃和常温（12℃~15℃）下贮藏，测定贮藏期间经壳聚糖处理以后草莓的失重率，可溶性固形物的含量、VC含量、总糖含量、总酸含量和呼吸强度的变化，研究壳聚糖涂膜对草莓果实保鲜的影响。试验结果表明，在草莓的贮藏中，壳聚糖涂膜处理对草莓有一定的保鲜作用，以浓度1.25%壳聚糖溶液处理保鲜效果最佳。尤其是在4℃条件下，浓度1.25%壳聚糖溶液处理明显降低了草莓果实的腐烂程度与失重率，延缓了果实贮藏后期可溶性固形物、有机酸含量、总糖含量以及VC的降低，减少了呼吸损耗，提高了草莓果实贮藏期间品质。

The experiment with seven or eight ripe strawberry on strawberry fruit as material , the different concentration of chitosan treatment, and at 4℃and at room temperature to 12℃-15℃under storage, measured during the storage of strawberry treated by chitosan after the weight loss rate, soluble solids content, vitamin C content, total sugar content, total acid content and the changes of respiration intensity, study of chitosan coating on preservation of strawberry fruits effect. The test results showed that, in the strawberry storage, chitosan coating on strawberry has certain effect, with a concentration of 1.25 % chitosan solution preservation effect best. Especially under the condition of 4 DEG C, the concentration of 1.25%chitosan solution treatment significantly reduces the strawberry fruit decay degree and rate of weight loss, delay fruit storage period of soluble solids, organic acid content, total sugar content and vitamin C reduce, decrease of breathing loss, improves the quality of strawberry fruit during storage.
