Embodiment 1

[0027] Example 1: Intelligent pre-cooling treatment combined with segmented controlled atmosphere storage to control tomato chilling injury system

[0028] Intelligent pre-cooling treatment combined with segmented controlled atmosphere storage system to control low-temperature chilling damage of tomatoes, including a sensor detection module, a data acquisition module, a wireless communication module, a terminal and a control system; detection, and then collect the data through the data acquisition module connected with the sensor detection module, and then transmit the change data to the terminal through the wireless communication module connected with the data acquisition module; the sensor detection module is also connected with the control system, when the terminal reads After the sensor detects the data, the environmental parameters are controlled through the control system.

[0029] The sensor detection module specifically includes a carbon dioxide detection module, an et...

Embodiment 2

[0034] Example 2: Intelligent pre-cooling treatment combined with segmented controlled atmosphere storage system to control low-temperature chilling damage of broccoli

[0035] The composition of the system structure is the same as in Embodiment 1.

[0036] Select 1000g of fresh, non-rotten and uniform broccoli, and pre-cool it at 4°C (the ambient temperature is 25°C), and collect the carbon dioxide concentration during the pre-cooling process in real time. When the pretreatment time is 65 minutes, the volume of carbon dioxide Reaching 2%, at this time the breathing intensity is reduced, and the pre-cooling treatment is over.

[0037] Stored at low temperature at 7°C, according to the characteristics of respiration and metabolism, carry out staged controlled atmosphere preservation. At the initial stage of storage (0-12 days), the high-density polyethylene bag (HDPE) spontaneously adjusts the atmosphere. On the 13th day of low-temperature storage, the ethylene concentration re...

Abstract

The invention discloses an intelligent pre-cooling treatment and sectioned controlled atmosphere storage combined system for controlling low-temperature cold damage of cold-sensitive fruit vegetable type vegetables and belongs to the technical field of intelligent control on food quality. The system comprises a sensor detection module, a data acquisition module, a wireless communication module, a terminal and a control system, wherein the sensor detection module detects carbon dioxide, ethylene as well temperature and humidity in a preservation chamber, then the data acquisition module connected with the sensor detection module acquires data, and the wireless communication module connected with the data acquisition module sends the data to the terminal; the sensor detection module is also connected with the control system, and the control system controls environmental parameters when the terminal reads the sensor detected data. Compared with existing physical and chemical analysis methods and artificial sensory analysis, the system has the advantages that to-be-tested samples cannot be damaged, the task load is small, and the objectivity and efficiency are higher.

Description

technical field [0001] The invention relates to a system for controlling low-temperature chilling injury of cold-sensitive fruits and vegetables in combination with intelligent precooling treatment combined with segmented controlled atmosphere storage, and belongs to the technical field of food quality intelligent control. Background technique [0002] Harvested fruits and vegetables, as living organisms, undergo physiological and biochemical reactions (such as the release of endogenous ethylene) continuously under certain storage conditions to accelerate the ripening and aging of fruits and vegetables. Temperature affects the physical, chemical and mutagenic reactions in fruit and vegetable storage, and is one of the important factors that determine the quality of fruit and vegetable storage. Cold-sensitive fruits and vegetables are prone to chilling injury when stored at an unsuitable temperature, the texture of the fruit and vegetable softens, the phase transition of the ...
