Method for treating tomato utilizing high pressure alternation electric field

Abstract

The invention relates to an application of high voltage electric filed in fruitage, in particular to a method for treating tomato with an alternative electric field. The method of the invention solves such critical problems of the prior art as long time for treating tomato under a constant high voltage electrostatic field , complicated operation and big electricity leakage while a high voltage isloaded. The tomatoes are placed in a high voltage alternative electric field environment at a frequency of 40kHz, an electric field intensity of 200kV / m and treated for 2 hours at a time, which can delay the ripening process of fruitage such as reddening and softening. The invention has the effects of deferring the hardness of fruitage, the decrease of soluble sugar content in the fruitage and chlorophyll content in fruit peel, the rising of titratable acid and lycopene content, etc.

Description

The method of treating tomato with high voltage alternating electric field technical field The invention relates to the application of a high-voltage electric field on fruits, in particular to a method for treating tomatoes with a high-voltage alternating electric field. Background technique There are many domestic researches on the preservation of fruits and vegetables by electric field treatment. However, most of them are carried out in the form of an electric field called a high-voltage electrostatic field, and test reports have shown the potential of this storage method. Experiments have found that electrostatic field fresh-keeping storage is a better storage method for some difficult-to-storage fruits and vegetables with high water content. According to a large number of experimental results, the high-voltage electrostatic field is beneficial to the growth of plants and the inhibition of microorganisms, the processing of agricultural products, especially the preserva...
