Agaricus bisporus is a common edible fungus, which is rich in protein, vitamins, minerals and other nutrients. It is one of the important ingredients on the table. However, during the growth and storage of agaricus bisporus, it is vulnerable to various fungi and bacteria, leading to quality problems such as plaque and decay, which reduces its commercial value and food safety.

In order to protect the quality and safety of agaricus bisporus, people often use sodium metabisulfite as a preservative and fungicide. sodium metabisulfite can not only effectively control the microbial pollution and corruption of Agaricus bisporus, but also improve its appearance, extend its fresh-keeping period and enhance its nutritional value.

Effect of Sodium Metabisulfite on Agaricus Bisporus

The results showed that sodium metabisulfite had some effect on the color of agaricus bisporus. During storage, sodium metabisulfite will be decomposed into sulfite and sulfur dioxide. These compounds will have a certain impact on the pigment structure of agaricus bisporus, making its color more pale. In addition, sodium metabisulfite may also cause some spots and color differences on the surface of agaricus bisporus, reducing its appearance quality.

However, after proper dosage control and treatment, sodium metabisulfite can still maintain the good color of agaricus bisporus. For example, agaricus bisporus can be quickly soaked in sodium metabisulfite solution containing 0.02% -0.04% for about 30 seconds after picking, and then washed with clean water. This treatment method can effectively inhibit the microbial pollution and corruption of agaricus bisporus, and will not have too much impact on its appearance and nutritional value.

When using sodium metabisulfite, the safe use standards and dose limits should be strictly observed to ensure the safety and quality of agaricus bisporus.
