Abstract

The invention relates to a mango preserving technology. In order to achieve integrative pre-plucking and post-plucking preserving effect, the invention comprises four composite preserving pretreatment measures of disinfectant and calcium fertilizer spraying before mango plucking and heat treatment, rot-proof film-coating preservative treatment and ethylene inhibitor treatment after the plucking. The rot-proof film-coating preservative comprises 0.25 percent to 2 percent of glucomannan or/and 0.25 to 2 percent of CTS with 95 percent degree of deacetylation, 0.1 to 1 percent of sucrose fatty acid ester or/and 0.1 to 1 percent of glycerel monostearte, 0.1 to 0.5 percent sorbitol or glycerol, 0.5 to 1.5 percent of calcium chloride or calcium citrate, 0.05 to 0.1 percent of potassium sorbate, 0.01 to 0.1 percent of one or more of the following ingredients: iprodione, Sportak and mancozeb, 0.005 to 0.01 percent of gibberellin and 0.025 to 0.05 percent of vitamin K. The invention can decrease the respiratory intensity, postpone the respiratory climacterics, delay the postripeness time and prolong the freshness period of mangos. Compared with the prior art, the freshness period of the mangos can be prolonged by 10 to 20 days.

Description

technical field [0001] The invention relates to a mango antiseptic and antistaling agent, a preparation method thereof and a method for mango post-harvest treatment, to better cooperate with the application of storage methods such as normal temperature storage, refrigeration, and controlled atmosphere storage, and to combine post-harvest treatment with storage methods, Form a complete set of mango fresh-keeping storage and transportation chain, effectively prolong the storage life and shelf life of mango. Background technique [0002] Mango (Mangiferaindica L.) belongs to the Anacardaceae plant, drupe fruit, a kind of precious fruit in the tropics. It is famous for its beautiful fruit shape, beautiful color, sweet flesh, sweet smell and fragrance. It is known as the "king of tropical fruits". The nutritional value of mango is very high. Ripe mango pulp has a high water content (about 82%), sugar 14% to 16%, soluble solids 15% to 24%, and 66 kcal per 100 grams; vitamin A cont...
