Chinese yam preservation microbial agent and method for using microbial agent to retain freshness of Chinese yam at normal temperature

Abstract

The invention discloses a Chinese yam preservation microbial agent and method for using microbial agent to retain freshness of Chinese yam at the normal temperature. The microbial agent is prepared from, by weight, 10 parts of deep-layer soil, 2-3 parts of water and 0.05-0.1 part of slime prepared from EM bacterial liquid, wherein the viable amount of the EM bacterial liquid is larger than or equal to 2 billion microorganisms / ml. The method for retaining the freshness of the Chinese yam at the normal temperature comprises the steps of removing the basal part of stems of the to-be-stored Chinese yam for slitting, immediately using the Chinese yam preservation microbial agent for sealing, uniformly adhering slime which is 1-3 mm in thickness at the notches of Chinese yam, loading the Chineseyam into a box of which the lining is provided with a light-proof packaging bag, uniformly spraying EM bacterial liquid diluent on each layer of Chinese yam in the packaging process, doubling the light-proof packaging bag up to be placed at the ventilated place to be naturally cooled, when the temperature is lowered to 0-5 DEG C, putting the box into a warehouse, and storing the Chinese yam at the normal temperature. By means of the Chinese yam preservation microbial agent, the mouthfeel and the nutritive components of the Chinese yam cannot be damaged; meanwhile, the storing method of the Chinese yam is simple and feasible, low in cost, and easy to operate, the storage time is long, and the Chinese yam preservation effect is good.

Description

technical field [0001] The invention relates to a fresh-keeping storage technology for vegetables, in particular to a normal-temperature fresh-keeping technology for Chinese yams. Background technique [0002] Yam, that is, yam, also known as yam, yam, yam, yam, sweet potato, and jade, is a vegetable that is very nutritious and has a variety of nourishing and medicinal effects. Among vegetables, yam is a storage-resistant vegetable, but it is not easy to store for a long time under normal conditions, especially the cut part of yam, which is easy to rot. [0003] The prior art generally adopts the method of dipping lime in the prior art for yam fresh-keeping. For example, the yam fresh-keeping technology disclosed by the invention patent No. 200710015376. , use sodium hypochlorite to humidify the filling and store it at a constant temperature after filling. This storage method can also be stored for a long time, but the yam cuts treated with lime powder use the strong bacte...
