Modified atmosphere packaging design expert system of fruits and vegetables

Abstract

The invention relates to the field of preservation technology, in particular to a modified atmosphere packaging system. The modified atmosphere packaging design expert system of fruits and vegetables comprises an information input module, a micro-processor system connected with the information input module and a displayer connected with the micro-processor system and comprises the steps of inputting the size parameters of a film bag by utilizing the information input module; calculating the volume of the film bag and then confirming the maximum aeration volume of the film bag by utilizing themicro-processor system; inputting the packed weight and the initial gas volume by utilizing the information input module; and confirming the packed weight and the initial gas volume when judging thatthe sum of the volume of main body of the fruits and the vegetables and the initial gas volume is not more than the maximum aeration volume by utilizing the micro-processor system. By utilizing the technical scheme, the defects of big workload, more time-consuming and high cost of an experiment are overcome and the modified atmosphere packaging of the fruits and the vegetables is judged through autonomously inputting the known packaging parameters and imitating the packaging effect by a user to confirm the suitable packed weight and the initial gas volume.

Description

technical field [0001] The invention relates to the technical field of freshness preservation, in particular to a modified atmosphere packaging system. Background technique [0002] Modified Atmosphere Packaging (MAP) is an advanced fresh-keeping packaging method for fruits and vegetables. Its principle is to use the respiration of fruits and vegetables in the packaging and the air permeability of the packaging film to change the atmosphere in the packaging environment by using artificial or natural accumulation methods. kind of low O 2 , high CO 2 Microenvironment, in order to achieve the purpose of inhibiting the respiration of fruits and vegetables, delaying the metabolic process of fruits and vegetables, and prolonging their storage period. [0003] In recent years, modified atmosphere packaging technology has been widely used in the fresh-keeping technology of fruits and vegetables, and has accumulated certain experience. However, these studies are mainly based on th...

Problems solved by technology

However, these studies are mainly based on the experience and estimation of researchers to initially select packaging films, and then conduct modified atmosphere packaging experiments to finally determine the appropriate packaging method. This makes the establishment of modified atmosphere packaging conditions time-consuming, expensive, and scattered research. The reproducibility of the storage effect is very high, and the reproducibility of the storage effect is poor, and there is a lack of unified theoretical guidance. Therefore, the modified atmosphere packaging of fruits and vegetables cannot be well promoted and applied.
