Abstract

The invention discloses a drying preservation method of mangos and relates to the technical field of fruit preservation. The preservation method of the mangos includes the following steps: soaking the mangos in a mixed solution of perchloric acid and acetic acid for 5-10min, performing rinsing with clear water for one or two times, performing air-drying at a room temperature and removing rotten or damaged fruits; dissolving starch in ethyl alcohol, then adding potassium sorbate and sodium benzoate and performing dilution by adding water so as to obtain a coating agent for preservation, wherein the mass concentration of the starch is 15%-20%, and the mass concentration of the potassium sorbate is 1%-2% and the mass concentration of the sodium benzoate is 0.3%-0.5%; soaking the obtained mangos in the coating agent, performing dip-coating and performing air-drying till a thin film forms on the surface of each of the mangos; and spraying sodium polyacrylate solution with a concentration of 0.05%-0.1% on paper bags and air-drying the sprayed paper bags.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit preservation, in particular to a method for preserving and drying mangoes. 【Background technique】 [0002] Known as the "King of Tropical Fruits", mango has high nutritional value and is a tropical fruit with high development value. Mango is a typical climacteric fruit. When the fruit ripens in hot and rainy summer, the metabolism of the fruit is vigorous. After harvest, there is an obvious post-ripening process. The starch in the fruit will gradually convert into sugar, the acidity will decrease, and the color of the fruit will turn from green to yellow. , the hardness is reduced, and there will be water produced by respiration on the surface of the fruit, which will easily make the mango decay, deteriorate, and rot. Mango is a tropical plant. Chilling injury will occur at about 10C°, and the peel will turn black. It is not suitable for low temperature storage and transportation. Therefore, it ...
