Composite processing method for preventing corrosion, keeping fresh and clearing agricultural chemical after picking cherry tomatoes

Abstract

The invention discloses a composite processing method for preventing corrosion, keeping fresh and clearing agricultural chemical after picking cherry tomatoes. The composite processing method comprises the following steps of: choosing cherry tomatoes in a hard-ripe stage, soaking by hot water and storing, wherein the hot water contains sodium bicarbonate, the concentration of the sodium bicarbonate in the hot water is 1.5-2.5 percent (m / v), the temperature of the hot water is 45 DEG C, the soaking time of the cherry tomatoes is 8-12 minutes, and the storing temperature is no higher than 20 DEG C. The cherry tomatoes do not have a cracking phenomenon after being soaked in the hot water containing sodium bicarbonate at 45 DEG C. The composite processing method can delay the decrease of the fruit hardness and the soluble solids of the cherry tomatoes, reduce the generation and the development of rottenness and has optimal clearing effect for agricultural chemical carriomycin.

Description

technical field [0001] The invention relates to a technique for antiseptic preservation and pesticide removal of fruits and vegetables, in particular to a compound treatment method for antiseptic preservation and pesticide removal of postharvest cherry tomatoes. Background technique [0002] Cherry tomato (Lycopersicon esculentum) is a 1-year herbaceous plant belonging to the family Solanaceae. It has been planted in large quantities in many areas in China, and its output is relatively large. The diameter of the fruit is about 1 to 3 cm, bright red and clear, sweet, seedless, good in taste and high in nutritional value, and is deeply loved by consumers. Cherry tomato is a typical climacteric fruit. The fruit is easy to become soft and rotten after harvest, and its quality is reduced. Infection, severe disease occurs, resulting in 20-30% rot loss, the highest can reach about 50%. [0003] For a long time, the use of various fungicides during the pre-harvest hard ripening pe...

AI Technical Summary

Problems solved by technology

[0005] At present, the combination of heat treatment and sodium bicarbonate for antiseptic preservation of cherry tomatoes is still blank at home and abroad

In addition to the fresh-keeping effect, the impact of this composite fresh-keeping treatment on the pesticide residues in fruits and vegetables has not been reported, and the problem of pesticide residues is directly related to food safety and export trade.
