Abstract
The invention belongs to the nuisanceless working process technical field of vegetables and fruits, and in particular to a kind of high-quality broccoli non-pollution processing method.Specifically, harvesting meets the broccoli of commercial specification, after the completion of extracting, after broccoli flower footpath otch dips processing in 0.02 0.03% Tea Polyphenols solution, processing center is delivered in vanning, carry out expelling parasite, except agriculture is residual, fresh-keeping, drying process, the significant extension that the broccoli storage period after being handled through this law obtains, commodity rate and quick-fried rate index can also maintain higher standard during storage.
Description
Technical field
The invention belongs to the nuisanceless working process technical field of vegetables and fruits, and in particular to a kind of nuisanceless place of high-quality broccoli
Reason method.
Background technology
Broccoli also known as broccoli, broccoli, sprouting broccoli, Italian cabbage mustard, stem cabbage, belong to Cruciferae Brassica genus
Wild cabbage mutation, it is edible with the tender stem for gathering bud, it is nutritious, containing protein, sugar, fat, vitamin and carrotene, battalion
Part is formed to occupy first of similar vegetables, broccoli mineral composition than other vegetables more comprehensively, calcium, phosphorus, iron, potassium, zinc, manganese etc.
Content is all very abundant, and the cabbage rolls than belonging to Cruciferae are higher by a lot.Broccoli may most be exactly significantly to have anti-cancer
Effect of anticancer, in addition to anticancer, broccoli also containing abundant ascorbic acid, can strengthen the detoxification ability of liver, improve
Immunity of organisms.And wherein a certain amount of flavonoid substances, then there is the function of regulation and prevention to hypertension, heart disease.Meanwhile,
Broccoli belongs to high fiber vegetable, can effectively reduce absorption of the stomach to glucose, and then reduces blood glucose, effectively controls diabetes
The state of an illness.
Broccoli is primarily present problems with as one of popular vegetables after harvesting listing：
（1）Pesticide Residue；
（2）Broccoli harvest time is short, and bud is easily open to turn yellow, and loses commodity value, and bud is not shelf-stable, at normal temperatures, 1-2
It just chlorosis turn Huang, quality decline, after listing how fresh-keeping problem；
（3）Insect pest easily occurs in planting process for broccoli, and combines broccoli design feature, and disease pest is easy to be hidden in
Inside broccoli, it is more difficult to the problem of removing.
The content of the invention
To solve the problems with existed after broccoli harvesting listing of the present invention, spy provides a kind of high-quality broccoli without public affairs
Evil processing method.
The solution of the present invention is as follows：A kind of high-quality broccoli non-pollution processing method, specifically,
（1）5-6 days before broccoli harvesting, root applies 300-350 times of liquid of a thiamine, hereafter to harvesting, do not apply it is any it is fertile,
Water, when broccoli length to commercial specification, is harvested, and 3-4 piece leaflets around bouquet are retained during harvesting, broccoli is extracted, cuts
After the completion of taking, broccoli flower footpath otch dips processing 8-12 minutes in 0.02-0.03% Tea Polyphenols solution, and bouquet is piled up upward
Neatly, processing center is delivered in vanning；
（2）Broccoli is unloaded after case, and conveying is placed in cooling chamber, is 25-28 DEG C in initial temperature, with the speed of 1 DEG C of cooling per minute
Rate is gradually cooled to 3-5 DEG C, and is kept for 10-13 minutes at 3-5 DEG C, and broccoli is delivered to expelling parasite room out of cooling chamber, if
It is 28-30 DEG C to put room temperature in expelling parasite room, and indoor carbon dioxide content is 30-32%, is handled 80-88 seconds；
（3）Broccoli after processing is delivered to except in the residual process chamber of agriculture, broccoli is immersed in rice bran suspension, reflow treatment
3-5 minutes, pull out, rinse one time, be again dipped into ultra micro calcium powder+grape acid+algin+water by 5:1:1:1000 ratios are mixed
To fresh-keeping liquid in handle 6-9 minutes；
（4）Broccoli is placed in hothouse, bouquet is piled up neatly upward, using helium as drying air-flow, with 2.3-2.4m/s's
Flow velocity, broccoli surface moisture is dried completely.
It is preferred that, the broccoli for meeting commercial specification refers to broccoli bouquet in 12-15cm, and each small bud is not yet loose
The broccoli opened；
It is preferred that, when extracting, cut off along the wounded in the battle footpath 12-13cm in bouquet bottom, extract angle of inclination for 30 ° -35 °；
It is preferred that, the rice bran suspension is made by raw material of rice bran, and rice bran ultramicro grinding is mixed with the water of 5-6 times of volume
Uniformly, regulation pH is pumped into pot for solvent extraction to 1.2-1.5, acidic cellulase is inoculated with 3-5% ratio into pot for solvent extraction, 55
Stirring reaction 10-12 hours at DEG C, filtration, concentration leaching liquor, in 26-28%, obtains rice bran suspension to solid content；
It is preferred that, using helium as drying air-flow, dried by flower footpath towards bouquet direction.
Beneficial effect of the present invention is that broccoli nuisanceless disposal of the present invention is specific to harvest management, expelling parasite management, except agriculture
Residual management, dry this four procedure of management realization, wherein, root applies 300-350 times of liquid of thiamine before harvesting, can significantly improve bouquet
Compactness, is harvested during harvesting by standard, obtains the high-quality broccoli for meeting commercial standards, and 3-4 around bouquet is retained during harvesting
Piece leaflet reduces broccoli damage ratio, the preferred wounded in the battle footpath 12-13cm in bouquet bottom during harvesting in transportation to protect bouquet
Cut off, extract angle of inclination for 30 ° -35 °, minimize tangent plane cell trauma, it is molten in 0.02-0.03% Tea Polyphenols with reference to otch
Processing 8-12 minutes is dipped in liquid, can effectively prevent tangent plane brown stain, infection；
Expelling parasite management uses high concentration carbon dioxide expelling parasite, to avoid high concentration carbon dioxide processing that broccoli can be caused fickle in love brown
Become, special to make broccoli dormancy using gradually cooling method before treatment, carbon dioxide content is 30-32% indoors, handles 80-
88 seconds, attachment insect in broccoli inside can gradually climb out of, and this processing can dispel inside broccoli more than 87% insect；
The special rice bran suspension of the present invention has extremely strong absorption, degradation to the residual composition of agriculture, and is made up using rice bran of former material,
Secondary pollution will not be produced, broccoli is in rice bran suspension, reflow treatment 3-5 minutes, and the residual clearance of agriculture is more than 95.2%；
Broccoli through except agriculture it is residual after, be again dipped into ultra micro calcium powder+grape acid+algin+water by 5:1:1:1000 ratios are mixed
To fresh-keeping liquid in handle 6-9 minute, fresh-keeping liquid is in broccoli bouquet top layer formation a thin layer protective layer, except can reduce bouquet
Outside metabolism degree and nutrient consumption, green preservation effect is also preferable, and the supply phase can be extended under the broccoli normal temperature after being handled through fresh-keeping liquid
10-12 days, commodity rate protected green index more than 98.2% more than 87.7%；
Broccoli after being handled through fresh-keeping liquid uses inert gas helium for drying airflow drying, can effectively remove free moisture,
Dish body surface face pathogen can be suppressed simultaneously.
Embodiment
Embodiment 1, a kind of high-quality broccoli non-pollution processing method, specifically,
（1）5-6 days before broccoli harvesting, root applies 300 times of liquid of a thiamine, hereafter to harvesting, and does not apply any fertilizer, water, treats
