Abstract

The invention discloses a preservation method for mangoes. The method comprises the following steps of: (1) performing heat water treatment on mangoes: selecting the mangoes having no insect pests and damage, placing the mangoes in the hot water at the temperature of between 45 and 55 DEG C, and soaking the mangoes for 5 to 20 minutes, during which slightly turning the mangoes; (2) soaking the mangoes treated in step (1) by using the mixed solution of chitosan and sodium dehydroacetate for 2 minutes; and (3) drying the mangoes treated in step (1) by blowing and airing for package, storage and transportation. The preservation method has the advantages of well regulating physiological functions of fruits, effectively inhibiting the disease and decay of the fruits, keeping the moisture and color of the fruits, improving the quality of the fruits, obviously reducing the decay possibility of picked fruits at the normal or low temperature and prolonging a shelf Life (or price period), along with high suitability for tropical fruits, such as the mangoes and the like; besides, all the ingredients in the preservation method are natural materials or food additives so as to achieve nontoxic residue, environmental protection and no harm to human bodies.

In addition to being eaten fresh, the fruit can also be processed into a variety of foods. It is a tropical fruit with great development value. Mango is a climacteric tropical fruit. When it matures normally, it coincides with the high temperature and rainy season. The fruit metabolism is vigorous, and it ripens rapidly at room temperature. It is not resistant to storage. Mangoes are sensitive to low temperatures, and chilling damage occurs at around 10°C. When sealed and self-generating modified atmosphere packaging is used, odors often occur, which severely limits the long-distance transportation and sales of mangoes. The occurrence of mango postharvest disease is the main cause of loss during th...
