Abstract

The invention discloses a fresh-keeping method for muskmelons; the method comprises the following specific steps: 1), selecting medium well-done muskmelons, picking, performing an overshadow treatment on the picked muskmelons by using a reflecting film; 2), performing 1-MCP (1-methylcyclopropene) fumigation on the muskmelons; 3), soaking the muskmelons in water; 4), blowing to dry the surfaces of the muskmelons; 5), spraying a fruit wax containing a fresh-keeping agent on the muskmelons; 6), drying the surfaces of the muskmelons; 7), putting the muskmelons in a refrigerator in which the temperature is 0 DEG C to 1 DEC C and the relative humidity is 75% to 85%, and pre-refrigerating for 1-2 days; 6), packaging each muskmelon by a micro-pore modified atmosphere fresh-keeping film; and 9), suspending the packaged muskmelons in the refrigerator in which the temperature is 0 DEG C to 1 DEC C and the relative humidity is 75% to 85%. The fresh-keeping method for the muskmelons is reliable and effective, and is low in pollution and side effect.

Description

technical field [0001] The invention relates to a fresh-keeping method, in particular to a fresh-keeping method for melons. Background technique [0002] Melon is a nutrient-rich cultivated crop with a long history of planting, rich in protein, potassium, calcium, iron, phosphorus and vitamins. The cuticle and waxy layer of the melon peel are thin and easily damaged. The water content of the fresh pulp is 80%-90%, and the sugar content is 8%-20%, which is very conducive to the reproduction and growth of pathogenic bacteria. In addition, the temperature, humidity and The daily temperature difference is high, resulting in a very high rot rate when the melons are placed at room temperature after picking. [0003] In order to prevent the muskmelon from rotting during storage and transportation, it is often harvested when the melon is still very raw, which makes it difficult to display the unique sweet flavor and good quality of the muskmelon, greatly reducing its edible quality...
