Advantages and Disadvantages of Adding Preservatives to Brine Mushrooms

Plant Extracts:
Some plant extracts have good antibacterial and antioxidant properties and can be used to preserve brine mushrooms. For example, garlic extract contains allicin, which has a strong antibacterial effect. In the process of pickling mushrooms, an appropriate amount of garlic extract can be added (generally 0.5-1 grams of garlic extract per kilogram of pickled mushrooms) to inhibit the growth of mold and bacteria. In addition, rosemary extract is rich in antioxidant ingredients, such as rosmarinic acid, which can prevent the oxidation of oils and nutrients in pickled mushrooms and extend the shelf life. Usually 0.3-0.8 grams of rosemary extract can be added per kilogram of pickled mushrooms.

Organic Acids:
Lactic acid and citric acid are commonly used natural preservatives. Lactic acid can lower the pH value of pickled mushrooms and inhibit the growth of microorganisms. Adding 1%-2% lactic acid to the pickling solution can effectively extend the shelf life. Citric acid can not only adjust the pH value, but also complex with metal ions to prevent pickled mushrooms from changing color. It is more appropriate to add 0.5-1.5 grams of citric acid per kilogram of pickled mushrooms.

Although chemical preservatives can effectively extend the shelf life of Brine Mushroom, they may pose potential risks to human health, so they must strictly comply with relevant national regulations when used. For example, potassium sorbate is a common food preservative, and the maximum usage in pickled mushrooms is generally 0.05%-0.1% (based on the weight of the pickled mushrooms). When using chemical preservatives, they must be accurately measured to ensure that the usage is within the safe range, and the type and usage of the preservative must be marked on the product label to inform consumers.
