Embodiment 1

[0018] The invention discloses an air-conditioning method for controlling the damage of penicillium while preserving fresh fruits and vegetables. The following steps are specifically implemented: putting fruits and vegetables, ethylene remover and silica gel desiccant into an airtight container, and maintaining the air relative humidity in the airtight container at 75%. -95%, use the inflatable device to replace and charge the mixed gas in the airtight container, where O 2 The volume fraction of the mixed gas is 70%, CO 2 The volume fraction of the mixed gas is 30%, and then airtight preservation is sufficient, and at the same time, logistics transportation can be carried out.

Embodiment 2

[0020] The invention discloses an air conditioning method for keeping fresh fruits and vegetables while controlling the hazards of Penicillium fungus. Specifically, the following steps are carried out: putting fruits and vegetables, an ethylene remover and a fiber desiccant into an airtight container, and maintaining the air relative humidity in the airtight container at 75%. -95%, use the inflatable device to replace and charge the mixed gas in the airtight container, where O 2 The volume fraction of mixed gas is 80%, CO 2 The volume fraction of the mixed gas is 20%, and then it can be sealed and kept fresh, and can be transported in logistics at the same time.

Embodiment 3

[0022] The invention discloses an air conditioning method for controlling the hazards of penicillium while preserving fresh fruits and vegetables. The following steps are specifically implemented: putting fruits and vegetables, ethylene remover and montmorillonite desiccant into an airtight container, and maintaining the air relative humidity in the airtight container to 75%-95%, use the inflatable device to replace and charge the mixed gas in the airtight container, where O 2 The volume fraction of mixed gas is 90%, CO 2 The volume fraction of the mixed gas is 10%, and then it only needs to be airtight and kept fresh, and at the same time, it can be used for logistics transportation.

[0023] The present invention realizes the preservation of fruits and vegetables while also inhibiting the harm of Penicillium to fruits and vegetables. The present invention does not need to add any chemical antibacterial agent, is healthy and has no residue, and meets modern people's demand tr...

Abstract

The invention discloses a controlled atmosphere method capable of keeping fruits and vegetables fresh and controlling penicillium harm simultaneously. The controlled atmosphere method comprises the following steps of loading fruits and vegetables into a closed container, charging O2 / CO2 mixed gas in a certain volume proportion in a replacement manner, wherein the volume percentage of O2 in the mixed gas is 70% or above, and the remaining gas in the mixed gas is CO2, sealing the charged container, performing fresh keeping, and at the same time, performing logistics transportation. The controlled atmosphere method has obvious fresh keeping effects on the fruits and vegetables, and besides, penicillium damage can be notably reduced.

Description

technical field [0001] The invention provides an air conditioning method for controlling the damage of penicillium while preserving fresh fruits and vegetables, and belongs to the technical field of food preservation. Background technique [0002] Penicillium is a fungus belonging to the subphylum Ascomycota, the class Asterocystis, the order Phytomycetes, the family Phytomycetaceae, and the genus Penicillium. It is commonly found in rotten fruits, vegetables, and meat. It is a pathogen that causes serious damage to fruits and vegetables after harvest. . [0003] Due to the vigorous metabolic activity of harvested fruits and vegetables, the requirements for fresh-keeping technology are also relatively high. Controlled atmosphere is one of the more advanced and effective methods in today's fruit and vegetable preservation. It controls the O in the storage environment. 2 and CO 2 The proportion, temperature and humidity of fruits and vegetables are used to reduce the respir...
