Broccoli fresh keeping method suitable for logistics transportation

Abstract

The invention discloses a broccoli fresh keeping method suitable for logistics transportation. The broccoli fresh keeping method comprises the following steps of loading broccoli after sorting treatment in a closed container, displacing gas in the closed container into O2/CO2 fresh keeping mixed gas in a certain volume proportion, wherein according to different logistics transportation temperatures, the O2/CO2 gas volume proportions charged in the fresh keeping mixed gas are different, the volume percentage of O2 in the fresh keeping mixed gas is 55%-95%, and the remaining gas in the fresh keeping mixed gas is CO2; and sealing the container after gas charging for fresh keeping, and besides, performing logistics transportation, wherein the logistics transportation temperature is 0-25 DEG C.According to the broccoli fresh keeping method disclosed by the invention, storage and fresh keeping can be performed on broccoli, the broccoli fresh keeping method can be rapidly applied to a logistics transportation system, and the effect of keeping the broccoli fresh during transportation can be achieved.

Description

technical field [0001] The invention provides a broccoli fresh-keeping method suitable for logistics transportation, which belongs to the technical field of food fresh-keeping. Background technique [0002] Because of its low calorie, high dietary fiber and rich antioxidant substances, broccoli is very popular among consumers. [0003] However, broccoli is not resistant to storage. It loses water and wilts and turns yellow within 2-3 days at room temperature, rapidly losing its nutrition and market value. [0004] At present, the commonly used fresh-keeping technologies for fruits and vegetables mainly include low-temperature refrigeration, low-oxygen controlled fresh-keeping, film-modified atmosphere fresh-keeping, chemical agent fresh-keeping and ozone fresh-keeping, etc. [0005] Among them, the storage period of low-temperature refrigeration and fresh-keeping is short, and due to reasons such as infrastructure and transportation costs, the cold chain system is generally...

AI Technical Summary

Problems solved by technology

[0005] Among them, the storage period of low-temperature refrigeration and fresh-keeping is short, and due to reasons such as infrastructure and transportation costs, the cold chain system is generally not used in the transportation of fruits and vegetables in my country at present; the oxygen concentration is not easy to control in the later stage of low-oxygen fresh-keeping, and anaerobic respiration often occurs, which promotes some anaerobic respiration. Oxygen harmful microorganisms multiply; air-conditioning film has a certain fresh-keeping effect on fruits and vegetables, but at present, there are various types of fresh-keeping films in my country with different characteristics, and it is difficult to formulate a unified fresh-keeping standard even for the same variety of fruits and vegetables; there are chemical residues in chemical preservation; ozone Preservation alone has limited effect

[0006] It can be seen that the currently commonly used fresh-keeping technologies have certain defects or are not suitable for logistics and transportation.
