Abstract

The invention discloses a disease resisting and fresh keeping method for postharvest mangoes and relates to the technical field of fruit fresh keeping. The method comprises the following steps of harvesting, pretreatment, coating and packaging, wherein the step of pretreatment comprises the following step of putting the mangoes into a medical solution formed by a green banana skin extract, a fructus amomi extract and warm water with the temperature being 50 DEG C for soaking; and the step of coating comprises the following step of adopting a coating preservative containing nanometer bamboo charcoal, antimicrobial peptide, a guava leaf extract and a pine needle extract for treatment. By optimizing the coating preservative and a fresh keeping method, the disease resisting and fresh keeping method for the postharvest mangoes solves the problems of short fresh keeping time and low safety of the mangoes at present, effectively inhibit the rotting rate of the mangoes and prolongs the fresh keeping time. By using the fresh keeping method provided by the invention, the fresh keeping period is 44-58 days, and the rate of intact fruit is 95 percent or above; the shelf life at normal temperature is 4-7 days, the rate of intact fruit is 88 percent or above, and the mangoes are invariable in flavor and rich in fragrance.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit preservation, in particular to a disease-resistant preservation method for post-harvest mangoes. 【Background technique】 [0002] Mango is a typical tropical fruit, known as the "King of Tropical Fruits". However, the metabolism of mango is relatively strong after picking, and the fruit ripens quickly, and it is easy to be rotted by pathogenic bacteria such as anthracnose and pedicle rot. In the early stage, it mainly depends on the contact between diseased fruit and healthy fruit, and is transmitted by mycelium, with a high infection rate. After picking, the circulation process loses seriously, and the annual loss rate is as high as 30-50%. Therefore, the method of mango fresh-keeping is a hot spot of current research. [0003] At present, mango fresh-keeping methods mainly include decompression fresh-keeping technology, controlled atmosphere storage technology, film fresh-keeping technology, co...
