Abstract

The present invention discloses a fruit and vegetable additive-free fresh-keeping method without separation from a culture medium. The method comprises: carrying out disinfection on a storage space with ozone, selecting the plant with characteristics of no plant disease, no insect pest, and no mechanical damage, removing dead branch and yellow leaf, placing the survival fruit and vegetable plant, the edible fungus hypha, and the fruiting body in a movable matrix into a refrigerating cabinet, maintaining relative humidity of 80-85%, and carrying out refrigerating, gas adjusting, and light supplementing to adjust the optimal sense organ characteristics and the physical and chemical characteristics of the fruit and vegetable. The method of the present invention has characteristics of strong operability, green property, economy, environmental protection, and no additive, the stored fruit and vegetable has characteristics of bright and fresh color, green and full property, rich juice, pure taste, rich nutrition, and long storage period, and the method is suitable for prevention of fruits and vegetables from disease infections, easy discoloration, wilting and rottening during the fruit and vegetable stream warehousing and selling process.

Description

A kind of fruit and vegetable does not depart from the additive-free preservation method of cultivation matrix

Technical field

The present invention relates to a kind of fruit and vegetable preservation method.

Background technology

Fruit and vegetable contains the vitamin of abundant nutriment, particularly needed by human, mineral matter and dietary fiber, and be the indispensable non-staple food of people's daily life, its importance is only second to grain.

Fruit and vegetable due to short water content harvest time large, adopt rear easy infection disease, easy to change, wilt, rot to make it lose fresh and tender state, in logistic storage sales process, preservation technique is crucial, the preservation by low temperature, the quick-freezing fresh-keeping that adopt at present, subtracts that air pressure is fresh-keeping, Chemical treatment is fresh-keeping, radiation exposure is fresh-keeping, air ion is fresh-keeping, and some economic input is large, some is too numerous and diverse, some chemical agent exceeds standard harmful, color and luster, mouthfeel, nutrition, declines in various degree.

The present invention complies with the nature rule, keeps foundation not depart from growth substrate adjustment storage environment, can degrading pesticide residues by ozonization process, without the need to increasing input, environmental protection more, naturally fresh.Be aided with refrigeration, controlled atmosphere, light filling, regulate the organoleptic quality of fruits and vegetables and physical and chemical quality to reach best.

Summary of the invention

The object of the invention is to: provide one safety, convenient, economic, effective raising fruit and vegetable preservation quality, the method prolonged storage period.

In order to reach above object, the present invention adopts following technical scheme:

A kind of fruit and vegetable does not depart from the additive-free preservation method of cultivation matrix, and its feature comprises the following steps:

(1) environment disinfected: first with supersonic humidifier, 80 ~ 85% are adjusted to storage freezer space relative humidity, then carry out disinfection 15 minutes with 25ppm concentration of ozone.Sterilization is stopped to enter after 40 minutes.

(2) enter storehouse: select without disease and pest, mechanical damage plant, after extracing the yellow leaf of deadwood, short and small plant can as the case may be with piling of casing.By survive in removable matrix fruits and vegetables plant, hypha of edible fungus together with fructification, its foundation portion with for its growth matrix, the ripe hanging branch of fruit 7 ~ 8.Put into freezer, keep relative air humidity 80% ~ 85% with supersonic humidifier.

(3) refrigerated storage temperature is adjusted: according to various fruits and vegetables, the difference of temperature conditions is required and tolerant temperature, corresponding constant temperature fresh-keeping temperature is provided.

(4) controlled atmosphere: be filled with N according to fruits and vegetables different cultivars plant ₂, CO ₂, adjustment freezer O ₂with CO ₂content.

(5) light filling: carry out light filling to plant plant growth lamp according to fruits and vegetables different cultivars.

The present invention is bright fresh by the fruits and vegetables color and luster of refrigeration, controlled atmosphere, light filling storage, and dark green plentiful, juice multi-flavor is pure, nutritious, and storage period is long.

Described removable matrix refers to the nutriment of applicable plant strain growth.

Described plant refers to live, cuttage, be transplanted to culture medium is housed container in normally amass wealth by heavy taxation and support body fruits and vegetables.

Described plant foundation portion is included as: fruit and vegetable provides the coring of nutrient also to comprise mushroom vegetables for fructification and provides the mycelium of nutrient.

Detailed description of the invention

The present invention will be described for selected embodiment below, and embodiment described herein only for illustration of explanation the present invention, is not intended to limit the present invention.

Example one

(2) enter storehouse: select without disease and pest, mechanical damage green vegetables plant, extract Huang Yehou, the green vegetables plant survived in removable matrix is put into freezer, keep relative air humidity 80% ~ 85% with supersonic humidifier.
