Abstract

The invention discloses a preservation method for mangoes and relates to the technical field of fruit preservation. The method comprises the following steps: harvesting and pre-treating, coating and packaging, wherein pre-treating means soaking the mangoes in a drug solution composed of green banana peel extract, alpinia katsumadai extract and hot water at 50 DEG C, and coating means treating witha coating preservative containing nanometer bamboo charcoal, antimicrobial peptide, circium japonicum extract and lemon-scented gum extract. According to the invention, the problems of short preservation time and low safety of mangoes at present can be solved in the manner of optimizing the coating preservative and the preservation method; the rotting rate of mangoes is effectively restrained andthe preservation time is prolonged; the refreshing period is 45-60 days and the rate of intact fruit is above 95% according to the preservation method disclosed by the invention; under room temperature, the shelf life is 4-6 days, the rate of intact fruit is above 85%, the flavor is kept and the fragrance is strong.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit preservation, in particular to a method for preserving mango freshness. 【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, coating film fresh-keeping ...
