This study tested the effects of the application of aqueous extract and edible coating of chitosan had on the chemical, microbial, and sensory attributes of cashew's shelf life. An aqueous extract of leaf (0, 0.5, and 1% ) was added to chitosan solution (0, 0.5, 1% ) in the cashew's coating. Cashews were dipped into the coating solution and were kept in polyethylene terephthalate containers. The result showed that chitosan and aqueous extract of coating had significant effects on peroxide and thiobarbituric acid value ( < .05). There was significant reduction in the growth of mold/yeast and mesophilic bacteria with higher concentration of chitosan and aqueous extract ( < .05). The results of this study show chitosan aqueous extract of coating could be an effective preservative method for extending shelf life and improving the stability of cashew.
本研究测试了壳聚糖水提取物和可食用涂层对腰果保质期的化学、微生物和感官特性的影响。将叶水提取物（0%、0.5%和1%）添加到腰果涂层中的壳聚糖溶液（0%、0.5%、1%）中。将腰果浸入涂层溶液中，并保存在聚对苯二甲酸乙二醇酯容器中。结果表明，壳聚糖和涂层水提取物对过氧化物和硫代巴比妥酸值有显著影响（P<0.05）。随着壳聚糖和水提取物浓度的增加，霉菌/酵母菌和嗜温细菌的生长显著减少（P<0.05）。本研究结果表明，涂层壳聚糖水提取物可能是延长腰果保质期和提高其稳定性的一种有效保鲜方法。
