2. Refrigerator cold storage method

Nowadays, refrigerators are very popular, and many people will think of using refrigerators to preserve bamboo shoots. However, many people find that bamboo shoots often age seriously after they have been kept in the refrigerator for a period of time.

Therefore, to keep bamboo shoots without killing cells in the refrigerator, it is best to seal them with fresh-keeping bags to prevent excessive water loss of bamboo shoots. It is not recommended to keep raw bamboo shoots in a refrigerator for a long time.

3. Keep fresh in cold storage

The cold storage of bamboo shoots has a short shooting period and is concentrated on the market, which brings some difficulties to processing and transportation. Cold storage can effectively prolong the shelf life, but the fresh-keeping temperature should not be too low, otherwise, the bamboo shoot protein denaturation, tissue disintegration, can not be eaten. From the effect of cold storage, the better cold storage of bamboo shoot slices is-18 ℃, which can be refrigerated for more than 1 year, and the shelled fresh bamboo shoots can be refrigerated for about 1 month under the condition of temperature-5 ℃ and relative humidity above 90%. According to different cold storage purposes, different cold storage treatment methods can be adopted. The fresh food used in the market is mainly refrigerated for a short time, and the temperature is about 2 ℃ and the relative humidity is about 90%. Food factories that use sliced bamboo shoots for processing can mainly refrigerate raw bamboo shoots at a temperature of-18 ℃; they can also choose to refrigerate fresh bamboo shoots with shells under the conditions of-5 ℃ and 80%-90% relative humidity; restaurants, hotels and other catering service departments can peel shells and cut into pieces and refrigerate at about-5 ℃.
