Talking about the Storage and fresh-keeping of Mushroom

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, The main factors affecting the preservation of mushrooms are as follows: temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4 ℃ is the suitable temperature for mushroom preservation. In addition to quick freezing, freezing injury is easy to be caused when the temperature is less than 0 ℃. Water quality: when the content of iron or copper in the water is more than 2 mg / L, the mushroom color darkens and turns brown, so iron and copper utensils and tools are prohibited. Humidity: 95-100% required. Less than 90% of the color darkens and it is easy to open an umbrella and deteriorate. Gas composition: it contains important causes of decay, which can be inhibited by sterilization and adjusting pH value. Enzyme activity: polyphenoxy

The main factors affecting the preservation of mushrooms are as follows:

Temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4 ℃ is the suitable temperature for mushroom preservation. In addition to quick freezing, freezing injury is easy to be caused when the temperature is less than 0 ℃.

Water quality: when the content of iron or copper in the water is more than 2 mg / L, the mushroom color darkens and turns brown, so iron and copper utensils and tools are prohibited.

Humidity: 95-100% required. Less than 90% of the color darkens and it is easy to open an umbrella and deteriorate.

Gas composition: it contains important causes of decay, which can be inhibited by sterilization and adjusting pH value.

Enzyme activity: polyphenol oxidase is the main cause of mushroom browning.

1. Controlled atmosphere fresh-keeping: the mushrooms were treated with 0.05mm thick PE bag by special physical method. The results showed that the mushrooms were kept fresh and tender within 3-5 days by simple controlled atmosphere storage, and there was no browning, and the water loss rate was less than 1%. At present, the special physical fresh-keeping bag of Baileyuan mushroom with strong breathability is used to keep 1% oxygen concentration and 10-15% carbon dioxide concentration in the bag, which can keep the mushroom white within 5-8 days and have good freshness.

2. Cold storage: low temperature can keep mushrooms fresh and high quality. During the period of storage and transportation, it is most suitable to keep the temperature 0-3 ℃ and the relative humidity 90-95%. Packing with Baileyuan mushroom special fresh-keeping bag can also prolong the fresh-keeping period, keep fresh and tender and bright color.
