荔枝(Litchi chinensis Sonn.)是驰名中外的岭南佳果,但采收后三至四天便变褐变质。本试验用气调贮藏防止荔枝变褐。结果如下: 1.用气调方法可贮藏荔枝30～40天(贮藏温度是1～3 ℃),基本上保持荔枝的鲜红色泽和原有的风味。 2.糯米糍和淮枝气调贮藏合适的气体比例是3％CO_2和5％O_2。桂味气调贮藏合适的气体比例是5％CO_2和5％O_2。过高浓度的CO_2(5％以上)产生异味和褐变增多等生理伤害。 3.气调贮藏能较大幅度降低荔枝果皮多酚氧化酶活性。
Litchi (Litchi chinensis Sonn.) Is well-known Lingnan good fruit, but harvested three to four days after the browning metamorphism. This experiment with the atmosphere to prevent litchi browning. The results are as follows: 1. The method of adjusting the atmosphere can be stored litchi 30 to 40 days (storage temperature is 1 ~ 3 ℃), basically maintain litchi bright red color and the original flavor. 2. Appropriate gas ratio of glutinous rice and Huai-zi atmosphere storage is 3% CO_2 and 5% O_2. The suitable proportions of the aroma of cinnamon are 5% CO 2 and 5% O 2. Excessive concentrations of CO 2 (more than 5%) produce odor and browning increased physiological injury. Atmospheric storage can significantly reduce the litchi peel polyphenol oxidase activity.
