Oyster mushroom preservation method suitable for logistics transportation

Abstract

The present invention discloses an oyster mushroom preservation method suitable for logistics transportation. The oyster mushroom preservation method suitable for the logistics transportation comprises the following steps: sorted oyster mushrooms are loaded into a closed container; air in the closed container is replaced with O2 / CO2 preservation mixed gas at a certain volume ratio; according to different logistics transportation temperature, the volume ratios of the O2 / CO2 gas inflated into the preservation mixed gas are different; wherein O2 accounts for 65%-100% of the volume percentage of the preservation mixed gas; the balance is CO2; the inflated container is sealed for preservation; at the same time, logistics transportation can be conducted; and logistics transportation temperatureis 0-25 DEG C. The disclosed oyster mushroom preservation method can store and preserve the oyster mushrooms, also can be quickly applied to the logistics transportation system and achieves the effectof preserving the oyster mushrooms in the transportation.

Description

technical field [0001] The invention provides a fresh-keeping method for oyster mushrooms suitable for logistics transportation, which belongs to the technical field of food fresh-keeping. Background technique [0002] Pleurotus ostreatus is rich in nutrition and delicious, and is favored by consumers because of its rich protein and amino acids. [0003] However, Pleurotus ostreatus is not resistant to storage. It loses water, wilts, browns, and loses nutrition in 2-3 days at room temperature, which brings great difficulties to long-distance transportation. [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 tra...

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. The strength is high, and edible fungus undergoes anaerobic fermentation in a low-oxygen environment to produce peculiar smell and promote the reproduction of some anaerobic harmful microorganisms; 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 , even for the same variety of fruits and vegetables, it is difficult to formulate a unified fresh-keeping standard; there are chemical residues in chemical preservation; the effect of ozone preservation alone is limited

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