Embodiment 1

[0076] see figure 1 , the present invention provides a kind of anti-freezing damage early warning control method for improving the quality of cold chain cherries, comprising the following steps:

[0077] S1: Determine the quality index of cold chain cherries, quantify the quality index of cold chain cherries, and record it as q value;

[0078] The quality indicators include the fruit flavor, hardness, VC content, soluble solids, titratable acid, pH value, weight loss rate, moisture content and sensory evaluation of cherries; the quality indicators of cold chain cherries are quantified, and the quality The index is converted into a value according to the common formula mastered by those skilled in the art, so as to measure the change of the quality index more accurately; and the change value Δq of the quality index of cold chain cherries over time at different temperatures is determined;

[0079] It should be noted that the quality indicators of cold chain fruits and vegetable...

Embodiment 2

[0135] The present invention also provides an anti-freezing damage control device for improving the quality of cold-chain fruits and vegetables, including:

[0136] The cold-chain fruit and vegetable quality change value measurement module is used to quantitatively process the cold-chain fruit and vegetable quality indicators, and measure the change value of the cold-chain fruit and vegetable quality indicators over time after quantitative processing at different temperatures;

[0137] The freeze damage position determination and early warning module is used to use the temperature acquisition device to collect temperature data at multiple locations at different times in the transportation link to obtain the first temperature data, and according to the corresponding cold chain fruit and vegetable quality indicators and the first temperature data Determine the changing status of freezing damage of fruits and vegetables, if the changing status of freezing damage is freezing damage...

Abstract

The invention relates to a method and device for antifreeze damage early warning and control to improve the quality of cold chain fruits and vegetables, which can establish a quality index antifreeze damage early warning and control change model for the quality of cold chain fruits and vegetables at different initial temperatures, and perform self-adaptive control to determine the corresponding To determine the best anti-freeze damage control method. The method and device can effectively prolong the express storage period of fruits and vegetables without affecting the taste, quality and freshness of the fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of cold-chain logistics industry of agricultural products, in particular to a method and device for anti-freeze damage early-warning regulation and control for improving the quality of cold-chain fruits and vegetables. Background technique [0002] As fresh and perishable products, fruits and vegetables have extremely high nutritional value and are favored by consumers. After harvesting, fruits and vegetables are prone to browning, dehydration, softening, rot, and quality degradation, and are not resistant to storage and transportation. The winter temperature in the Northeast is around -10°C to -20°C all year round. During the 12-hour outdoor exposure period, the ordinary express aluminum foil insulation bag used in the traditional cold chain transportation insulation method cannot achieve the insulation effect, causing serious frostbite problems for fresh fruits and vegetables, and the quality and freshness...
