Problems solved by technology

Most of the pesticides used in fruits and vegetables are harmful to humans and animals. In theory, these fruits and vegetables must be harvested and sold in the market after the toxicity of the pesticides disappears. On the surface of vegetables or fruits, it is inevitable that there will be more or less pesticide residues, and there are potential food safety problems
[0003] Therefore, a variety of detergents for removing pesticide residues on the surface of fruits and vegetables have appeared on the market now. These detergents generally clean the fruits and vegetables by using enzyme preparations that can degrade pesticide residues on the surface of fr

Abstract

The invention provides an enzyme preparation for removing pesticide residual on the surfaces of vegetables and fruits and a preparation method of the enzyme preparation. The enzyme preparation comprises one or more enzymes and alkaline buffer salts, wherein each enzyme preparation is the particular preparation with aperture distributed from 50 to 500 nanometers. The enzyme preparation further comprises fillers with porous structures; and the enzyme preparation is prepared by the method comprising the following steps: pelletizing the mixing materials of one or more enzymes and fillers to obtain the enzyme particle mixture; embedding 45wt% to 55wt% of enzyme in the enzyme particle mixture into the filler; and then mixing the enzyme particle mixture and the water solution of the alkaline buffer salt through a fluidized bed. With the adoption of the enzyme preparation provided by the invention, the pesticide residual on the surfaces of the vegetables and the fruits can be completely and effectively removed; harmful microorganism on the surfaces of the vegetable and fruit can be removed; and the quality of the vegetable and fruit can be further improved.

Description

technical field [0001] The invention relates to an enzyme preparation and a preparation method thereof, in particular to an enzyme preparation for removing pesticide residues on the surface of fruits and vegetables and a preparation method thereof. Background technique [0002] In order to prevent the impact of pests and diseases on the quality of fruits and vegetables, pesticides are widely used in the process of growing fruits and vegetables. Most of the pesticides used in fruits and vegetables are harmful to humans and animals. In theory, these fruits and vegetables must be harvested and sold in the market after the toxicity of the pesticide disappears. On the surface of vegetables or fruits, it is unavoidable that there will be more or less pesticide residues, and there are potential food safety problems. [0003] Therefore, a variety of detergents for removing pesticide residues on the surface of fruits and vegetables have appeared on the market now. These detergents g...
