1, the cold and fresh bamboo shoots have a short period of time, and they are listed on the market, which brings certain difficulties to processing and transportation. With cold storage can effectively extend the shelf life, but the preservation temperature can not be too low, otherwise, bamboo shoots protein denaturation, tissue disintegration, can not eat. Before bamboo shoots are stored in cold storage, attention must be paid to the following work. First of all, the cold storage is disinfected. Under normal circumstances, the disinfectant should be selected as a 2.9% formalin solution with low toxicity, and bamboo shoots with pests and diseases must be avoided in the cold storage. The stacking of refrigerated bamboo shoots should strive to be ventilated and ventilated. There must be a gap between the equipment used to hold bamboo shoots, and the temperature and humidity should be stable. Avoid moving them during refrigerating. Do not mix with other vegetables. Refrigerated bamboo shoots should be selected from bamboo shoots in the high season or bamboo shoots in the later period, which is more meaningful for extending the processing period and regulating the market. Judging from the effect of cold storage, the effect of bamboo shoots that have been treated differently is similar to that of bamboo shoots. Refrigerated bamboo shoots are stored at a negative temperature of minus 18 degrees Celsius and can be refrigerated for more than one year. Fresh bamboo shoots with a temperature of minus 5 degrees Celsius and relative humidity above 90% can be refrigerated for about 1 month. According to different refrigerated purposes, different refrigerating methods can be adopted. For the fresh market, we mainly use short-term refrigerated storage, and we choose to refrigerate under the conditions of a temperature of about 2 degrees Celsius and a relative humidity of about 90%. Food factories that use bamboo shoots for processing can use cold-stored raw bamboo shoots as the main ingredient at negative 18 degrees Celsius; alternatively, they can be refrigerated with shelled fresh bamboo shoots at negative 5 degrees Celsius and 80%-90% relative humidity; Hotels and other catering services can be peeled and cut into pieces at a temperature of minus 5 degrees Celsius. 2. Apply fresh-keeping agents to keep fresh bamboo shoots weighing 4 kg in each box. Place 2 bags of air-permeable paper bags containing about 10 grams of activated charcoal or quicklime. Japan generally applies this method to preserve freshness.
