摘  要:
研究不同浓度乳酸钙溶液处理对鲜切西瓜呼吸速率、硬度、可滴定酸含量、pH等各项指标的变化情况。结果显示,乳酸钙处理在储藏期内,不仅有效地降低鲜切西瓜呼吸速率,提高鲜切西瓜硬度,并且抑制微生物生长。因此,乳酸钙处理可以有效保持鲜切西瓜品质,其中浓度为2.5%的乳酸钙处理的效果最佳。

摘  要:
Effect of calcium lactate treatment on fresh-cut watermelon was evaluated.The calcium lactate treatments not only decreased the respiratory rate of the fresh-cut watermelon,but also increased the hardness of the fresh-cut watermelon.Moreover,the calcium lactate treatment inhibited the improvement of microbial population of watermelon.Therefore,the calcium lactate treatment at content of 2.5% showed the best capacity to keep quality of fresh-cut watermelon as the original one.
