Why do mushroom in brine can keep fresh?
Jul 03, 2024
Mushroom in brine, as a special processed food, the reason why this mushroom can stay fresh for a long time is mainly due to the following aspects:
Brine soaking: In the preparation of brine mushrooms, the mushrooms are soaked in a high concentration of brine. This saltwater environment can effectively inhibit the growth of microorganisms, reducing the possibility of mushroom spoilage.
The antibacterial effect of salt: Salt is a natural preservative that absorbs water in mushrooms and reduces water activity, thereby inhibiting the growth of bacteria and fungi and extending the shelf life of mushrooms.
Low temperature storage: Brine mushrooms usually need to be kept at a lower temperature during processing and storage. Low temperature can slow down the metabolic activity of microorganisms and further extend the shelf life of mushrooms.
Sealed packaging: During the packaging process, brine mushrooms are usually sealed in non-breathable packaging materials to reduce oxygen exposure and prevent oxidation and deterioration of the mushrooms.
Sterilization treatment: In some cases, salted mushrooms are also sterilized before packaging, such as heat treatment or ultraviolet irradiation, to further eliminate possible microorganisms and ensure the safety and freshness of the product.
The right pH: Brine mushrooms usually have a low pH, which helps to inhibit the growth of certain microorganisms and keep the mushrooms fresh.
Transport and storage conditions: During transport and storage, brine mushrooms need to follow strict conditions, such as avoiding high temperatures and direct sunlight, in order to maintain their optimum condition.
