Abstract
The invention provides a Medicagohispida Gaertn controlled atmosphere freshness keeping method. The method mainly comprises the following steps: 1, sorting fresh Medicagohispida Gaertn, cleaning, draining and pre-cooling; 2, carrying out controlled atmosphere packaging of CO2, O2 and N2, wherein a volume ratio of CO2 to O2 to N2 is 1-2:4-16:83-97; and 3, carrying out freshness keeping storage at 0-5DEG C. Compared with the prior art, the method in the invention realizes a best Medicagohispida Gaertn storage freshness keeping effect by adjusting the proportions of CO2, O2 and N2 in a Medicagohispida Gaertn packet, and prolongs the freshness lifetime of the Medicagohispida Gaertn to above 10d.
Description
Technical field
The present invention relates to a kind of processing of farm products method, be specifically related to a kind of processing method of seedling grass, be applied to agriculture field.
Background technology
Seedling grass, formal name used at school medicago hispida, has another name called bur clover, three leaf vegetables, toothed burclover etc., belongs to annual herb plant.Because cold resistance, drought resistance, the diseases and insect pests resistance of seedling grass are strong, thus whole growth course without to fertilize, control insect pest, be pollution-free green food truly.It contains multivitamin, amino acid, food fiber, useful inorganic salts and compared with multiple trace element, contain the abundantest vitamin K, the height becoming minute, almost one cut vegetables on, other is as also quite abundant in protein, Alphalin, C, B content, is the vegetables that nutritive value is higher.The plantation at China's Jiangsu-zhejiang Shanghai Area one band with 2000 is historical, and the 60-70 age is used as green manure, and people are also as vegetable edible use sometimes, and custom is " crossing life grass ".For these years, the nutritive value of seedling grass, edibility are all fully used.Along with eating gradually of people, the development of agricultural economy and scientific and technical raising, seedling grass appropriate scale of operation degree progressively improves, and the utilization of seedling grass is edible to people from green manure to feed advance.
In recent years, along with the development of agricultural economy and the adjustment of the edible structure of people, seedling grass industry has been moved towards commercialization gradually, but it is very little as seedling grass, to sell circle, and little seedling grass moves towards large market, metropolis.The fresh-keeping problem of seedling grass has become the bottleneck of seedling grass industrial circulation link, and preservation technique becomes difficult point, after conventional seedling grass is gathered, can only about one day, and the yellow of will generating heat is rotten.Generally people also take ice block cooling, the fresh-keeping sale of accumulating, but actual effect is poor, and fresh-keeping problem becomes the obstacle of seedling grass industry.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of seedling grass air regulating fresh-keeping method.
Technical scheme: for achieving the above object, the invention provides a kind of seedling grass air regulating fresh-keeping method, it mainly comprises the following steps:
