Abstract

The present invention discloses a fruit and vegetable antiseptic solution detection method and its detection control device. Said invention adopts a fixed-proportional dilution reduction method, and adopts the following steps: diluting high solution chlorine antiseptic solution, detecting and displaying pH value and temperature value of said antiseptic solution, and setting pH value upper limit and lower limit alarm values of said antiseptic solution. The detection control device for implementing said method is formed from pipeline system of solution to be detected, pipeline system of dilutingwater, mixing pipeline system, solution-supplementing pipeline system and detection control system.

Description

technical field [0001] The invention relates to a disinfectant detection method and a detection control device, in particular to a detection method and an intelligent detection control device for detecting high-concentration disinfectant. Background technique [0002] Food safety is currently a concern of consumers, and fruits and vegetables are widely consumed by consumers, so the safety of this type of food is particularly important. Cleaning and disinfection is an important process in the postharvest processing of fruits and vegetables, especially for the fast-growing fresh-cut fruit and vegetable products, cleaning and disinfection is very important. The quality of the sterilization effect during the cleaning process directly affects the fresh-keeping quality and shelf life of the product, as well as the food safety of consumers. Chlorine disinfectants are currently widely used fungicides in fruit and vegetable processing. Literature research results show that disinfect...
