Description

Muskmelon preservation method

Technical field

The present invention relates to a kind of preservation method, particularly a kind of muskmelon preservation method.

Background technology

Muskmelon is a kind of historical, nutritious raise crop of long plantation that has, and is rich in protein, potassium, calcium, iron, phosphorus and vitamin etc.Cuticula and the wax coat of muskmelon pericarp are thin, very easily damage, fresh fruit meat water content 80%-90%, sugar content 8%-20%, the utmost point is beneficial to pathogen breeding growth, and the temperature in picking time, humidity and temperature difference per day are all higher in addition, and while placing at normal temperatures after causing muskmelon to be plucked, rotting rate is very high.

In order to prevent that muskmelon from occurring to rot in transporting procedures, usually when muskmelon is also very raw, just gather, cause the sweet and refreshing local flavor of muskmelon uniqueness and good quality to be difficult to represent, greatly reduce its edible quality and the market competitiveness.In addition, if the place of production does not possess preservation technique and storage traffic condition, will certainly cause the consequence of " busy season is rotten, dull season is disconnected ".From industrialized development, along with the expansion of Muskmelon Planting area, need the technology of a set of fresh-keeping storing badly.

The maize ear rot pathogenic microorganism that causes during muskmelon storing is mainly fungi.Muskmelon all can be subject to infective pathogen bacterium latent infection in whole growth and development process, the reticulate pattern phase is the main period of pathogen latent infection, in addition, at muskmelon, gathers, preserves, in transportation and sales process, also can continue to be subject to infecting of microorganism, rot during causing muskmelon storage transportation and sales.At muskmelon, adopt in post processing, if the microorganism that can effectively kill Field infection and carry, the disease that can effectively reduce during muskmelon stores and transports occurs, and reduces rotting of muskmelon, improves its commodity value.

Summary of the invention

The object of the present invention is to provide a kind of reliable effectively, pollution and the little muskmelon preservation method of side effect.

A preservation method, comprises the following steps,

1) choosing ripe very likely muskmelon gathers;

2) muskmelon being carried out to 1-MCP fumigates;

3) muskmelon is soaked in water;

4) dry up muskmelon surface;

5) the fruit wax that spraying contains antistaling agent to muskmelon;

6) muskmelon surface is dried to processing;

7) muskmelon is put into temperature 0-1 ℃, the freezer precooling 1-2 days of relative humidity 75%-85%;

8) muskmelon is carried out to individual packing with micropore air-conditioning preservative film;

9) packaged muskmelon is hung and left in temperature 0-1 ℃, the freezer of relative humidity 75%-85%.

Preferably, step 1) in, after harvesting, in Piling up in Field process with reflective membrane to the muskmelon processing of sheltering from heat or light.Sunshine direct projection had both been avoided in this processing, had avoided again muskmelon to absorb heat temperature and had raise, and had slowed down the aging of muskmelon after adopting.

Preferably, step 2) described in, the stifling dosage of 1-MCP is 0.1-2 μ L/L, and the fumigation time under room temperature is 12-24h.

Preferably, step 3) coolant-temperature gage described in is 0-15 ℃, and soak time is 3-5 minute.Both reduce its respiration heat, completed again cleaning, removed earth and the microorganism on muskmelon surface.

Preferably, step 4) in, with cold wind, muskmelon surface is dried up to processing, with cold wind, dry up behind muskmelon surface and be placed in freezer and carry out secondary precooling, that has avoided better occurring in muskmelon storage damages to plants caused by sudden drop in temperature.

Preferably, antistaling agent step 5) is one or more in cinnamon essential oil, ambam, Tuzet, benomyl, antibacterial azoles, calcium chloride, gibberellin.

Preferably, the wax of fruit step 5) stirs formulated by the raw material of following mass fraction:

100 parts of shellac,

Propolis 5-10 part,

Shitosan 0.1-1.0 part,

0.5 part of acetic acid,

0.2 part of Tween-80,

0.4 part of glycerine.

Preferably, antistaling agent step 5) is 1-5:100 with the weight ratio of fruit wax.

Preferably, step 6) to and be coated with the dry processing the muskmelon surface of the fruit wax that contains antistaling agent carried out can be for naturally also selecting to dry up or other dry processing mode.If select, with cold wind, dry up that effect is better, with step 4) cold wind dry up auxiliaryly mutually, that has avoided better occurring in muskmelon storage damages to plants caused by sudden drop in temperature.

Preferably, the CaCO that in technique scheme, micropore air-conditioning preservative film used can have been processed for having added the titanate esters TC-2 through 2% of 10-30 mass fraction 3the microporous barrier of powder, micropore size is 0.01-10 μ m.

Muskmelon is carried out to 1-MCP stifling and with the fruit wax spraying that contains antistaling agent, not only blocked the breathing of synthesizing but also suppressed muskmelon of ethene, strengthened the water-retaining property of muskmelon; Use muskmelon micropore plastic wrap to carry out single fruit controlled atmospheric packing, then melon is hung in the freezer that leaves accurate temperature controlling in, can well control the respiratory intensity of muskmelon.

Adopt muskmelon preservation method of the present invention to have the following advantages:

1, can reliably effectively in the transporting procedures of muskmelon, to it, carry out fresh-keepingly, and the Perserving materials using in preservation process pollutes and side effect is all very little.Antistaling agent is the conventional material in food fresh-keeping process.Most of antistaling agents are all chemicals, have carcinogenic, teratogenesis and higher residual toxicity, have longer degradative phase, to environment, can cause serious pollution.Plants essential oil is a kind of volatile liquid extracting from fruit, blade, flower and root tissue, has strong smell and fragrance, can suppress consumingly or the microorganism such as kill fungi.At current phytopathogen, chemical bactericide is produced under the situation of drug resistance and day by day aggravation of residues of pesticides harm, plants essential oil is a kind of urgently disinfecting material leaved for development.Cinnamon essential oil is a kind of plants essential oil extracting from Chinese cassia tree, and it has good anti-microbial property, and nontoxic, edible, meets the requirement of preserving fruit and vegetable utilizing materials'use aspect.Shitosan is a kind of macromolecule cation polysaccharide, can form semipermeable membrane and regulate the physiological metabolism after Fruit at fruit surface, delay respiration, the antimicrobial acivity of induction fruits and vegetables, and energy biodegradation, nontoxic, safety, be applied to the preservation and freshness of many fruits as crude antistaling agent.Adopt cinnamon essential oil anti-staling coating made of chitosan, can, when reaching fresh-keeping object, environment not damaged.

2, the muskmelon that muskmelon preservation method of the present invention adopts picks while being ripe very likely, therefore can retain more sweet and refreshing local flavor and good edible quality than unripe watermelon banking system in the past.

3, by hanging with the good muskmelon of micropore air-conditioning preservative film individual packing to leave in temperature 0-1 ℃, the freezer of relative humidity 75%-85%, adopt air conditioned storage, respiration and the transpiration that can effectively suppress fruits and vegetables, delay the physiological metabolism process of fruits and vegetables, postpone rotten generation.The controlled atmospheric packing being used in conjunction with has been used and has been selected breathable film to regulate the gas component in packing.In the present invention, select breathable film mainly to adopt microporous barrier, it can regulate the gas component in packing effectively, promote gas exchange, reduce the humidity in packing, reduce the accumulation of Volatile Metabolites, very applicable for the fruit and vegetable food of humidity sensitive.
