Oyster mushroom fresh-keeping method suitable for logistics transportation

Abstract

The invention discloses an oyster mushroom fresh-keeping method suitable for logistics transportation. The oyster mushroom fresh-keeping method includes the following steps that sorted oyster mushroom is placed into a closed container, and gas in the closed container is replaced with a certain volume ratio of O2 / CO2 fresh-keeping mixed gas, wherein according to different transportation temperature, the volume ratio of the O2 / CO2 gas charged into the fresh-keeping mixed gas is different, O2 accounts for 65%-100% of the volume of the mixed gas, and the balance is CO2; the container charged with the mixed gas is sealed for preservation, at the same time, logistics transportation can be conducted, and the temperature of the logistics transportation is 0-25 DEG C. The oyster mushroom fresh-keeping method can not only be used for storing and preserving the oyster mushroom, but also be quickly applied to a logistics transportation system to achieve the effect of preserving the oyster mushroom in 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. 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. [0003] 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. Among them, the storage period of low-temperature refrigeration and fresh-keeping is short, and due to reasons such as infrastructure and transportation costs,...

AI Technical Summary

Problems solved by technology

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 the anaerobic fermentation of edible fungi in a low-oxygen environment produces odors and promotes the reproduction of some anaerobic harmful microorganisms; air-conditioning films have 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 fruit and vegetable variety, it is difficult to formulate a unified fresh-keeping standard; chemical preservation has the problem of chemical residues; ozone fresh-keeping alone has limited effect

[0004] It can be seen that the currently commonly used fresh-keeping technologies have certain defects or are not suitable for logistics and transportation.
