Description
Technical field
The present invention relates to oil tea mushroom technical field of preservation of fresh, the especially a kind of fresh-keeping side of oil tea mushroom ozone nitrogen Combined Treatment
Method.
Background technique
Oil tea mushroom is one of agrocybe, delicious, clear and melodious palatable, full of nutrition, is that people like edible edible
Bacterium.Oil tea mushroom is under general condition, it is more difficult to and storage and transport, 2-3d after fresh mushroom harvesting moisture will occur and largely scatter and disappear and atrophy,
Oil tea mushroom handle, lamella start brown stain, until rotting, cause in fruiting peak period, a large amount of fresh mushrooms concentrate on nearby selling in the market, make
At the mushroom market status that supply exceed demand, so that the price sharp fall of oil tea mushroom, seriously compromises the interests of mushroom grower, constrains
The development of oil tea mushroom industry, and in the area far from mushroom class production base, and because mushroom source lacks and causes the city of supply-less-than-demand
Field status.
In recent years, with the transformation of people's consumption idea, market is increasing to fresh fried flour mushroom demand, and for oil tea
The Study on preservation technique of mushroom is also developed and breaks through, and is mainly reflected in: cold storing and fresh-keeping, ozone fresh-keeping, chemical agent are fresh-keeping
And spontaneous controlled-atmosphere preservation；Cold storing and fresh-keeping is to inhibit the breathing of oil tea mushroom using natural low temperature or by reducing environment temperature
Metabolism and enzymology reaction, which makes the storage oil tea mushroom 2d at 25 DEG C occur to rot, and stores at 5 DEG C, can store
8d reduces the consumption of substance so that low temperature inhibits the respiration of oil tea mushroom；It is packed and is carried out using vacuum pre-cooling combination film
Cold storing and fresh-keeping can significantly extend the freshness date of oil tea mushroom, so that oil tea mushroom storage 10d not parachute-opening, not drying shrinkage, mycoderm are not
It falls off, compared with storing under room temperature, weight-loss ratio reduces 7%, and respiratory intensity declines 30%, Vc storage rate and improves 20.5%.Chemical agent
It is fresh-keeping, so that inhibiting the discoloration of oil tea mushroom, parachute-opening and the effect ruined using citric acid, sodium chloride, Vc etc., what is be composed
Oil tea mushroom is handled under composite preservative can save 6d, storage period not parachute-opening, smell is normal, brown stain at 10 ± 1 DEG C
Degree and respiratory intensity are significant lower.Ozone fresh-keeping is that oil tea mushroom is placed in certain density ozone environment, utilizes killing for ozone
Bacterium effect is next fresh-keeping, and oil tea mushroom stores at 20 ± 1 DEG C after ozone treatment 0.5min, and the breathing that can reduce oil tea mushroom is strong
Degree, reduces the generation of free amino acid, and conductivity to oil tea mushroom and weight-loss ratio variation have no significant effect, and 1-2min
Ozone treatment is then unfavorable for the fresh-keeping of oil tea mushroom.Spontaneous controlled-atmosphere preservation is fitted into after the harvesting of oil tea mushroom in turnover basket, passes through
Reduced pressure treatment overcomes moisture loss at about 5 DEG C of low temperature, reduces respiratory intensity, prevents ethylene from being formed and accumulated, reaches inhibition
PPO vigor delays mushroom body oxidation reaction speed, reduces nutrient matrix loss, prevents microbial reproduction, extends the mesh of mushroom body life time
, storage period, good mushroom rate was 97.5% up to 25d, and mushroom body items pear flower index substantially remains in horizontal when harvesting.
As it can be seen that in the prior art, oil tea mushroom preservation technology is haveed the defects that more, is caused fresh-keeping to oil tea mushroom fresh mushroom
Handle it is unsatisfactory, especially ozone carry out oil tea mushroom Preservation Treatment during, due to using pure ozone handle, lead to oil tea mushroom
Needing to control in the processing time is 0.5min, so that treatment conditions are particularly harsh, Preservation Treatment difficulty is larger；But also occur
The time is handled after 1-2min, the undesirable state of fresh-keeping effect will occur.In consideration of it, this researcher is to ozone treatment oil tea mushroom
Fresh mushroom fresh-keeping aspect is made that further research, and the condition for thereby reducing ozone treatment oil tea mushroom fresh mushroom is harshness, reduces
Preservation Treatment difficulty.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of oil tea mushroom ozone nitrogen joint
Handle preservation method.
It is achieved particular by following technical scheme:
Oil tea mushroom ozone nitrogen Combined Treatment preservation method, comprising the following steps:
(1) selection ninety percent is ripe, and the complete fresh mushroom body of ontology carries out sorting classification；
(2) pad sets wood pulp paper layer on turnover chamber interior wall, and fresh oil tea mushroom mushroom body is stacked and is fitted into turnover box, thickness is put in every stacking
Degree is 8-9cm, is isolated between layers using wood pulp paper layer, and top layer is closed using wood pulp paper layer；Realize water conservation moisture-keeping function.
(3) turnover box for filling oil tea mushroom fresh mushroom is put into controlled atmospheric packing bag, packaging bag is evacuated, be filled with smelly
Oxygen-nitrogen mixed gas after handling 0.3-2min, extracts mixed gas out until packaging bag is full, so that be vacuum in packaging bag,
It is put under refrigerated condition, stores.
It is preferred that the wood pulp paper layer is formed by the identical wood pulp paper of two sizes is stacked.Enhancing water conservation moisture-keeping functions.
It is preferred that the wood pulp paper with a thickness of 0.05-0.07mm.Reduce interlayer warming phenomenon.
It is preferred that the size of the wood pulp paper and the inside dimension of turnover box are adapted.The gas leak phenomenon that leaks out is avoided, is improved
It is retained moisture-retaining capacity.
It is preferred that the refrigeration be temperature be 2-4 DEG C at carry out.Respiratory intensity is reduced, the fresh-keeping period is extended, is reduced
Weight-loss ratio and rotting rate.
It is preferred that the ozone-nitrogen mixed gas mixed volume ratio is 1:0.3-1.5.Helping, which improves oil tea mushroom, protects
Fresh process weightlessness.
It is preferred that the ozone-nitrogen mixed gas mixed volume ratio is 1:1.
Compared with prior art, the technical effect of the invention is embodied in:
By carrying out the processing 0.3-2min in vacuum packaging bag using ozone and nitrogen mixed gas, not only make to oil tea mushroom
Mushroom body surface face has carried out sterilizing sterilization processing, and also reduces the time control of ozone treatment, so that the mixing in nitrogen is made
Under, ozone is improved to the destruction situation in oil tea mushroom mushroom body surface face, and then ensure at long period (1-2min or so), not
It fresh-keeping to oil tea mushroom mushroom body can impact, extend the oil tea mushroom fresh-keeping period, be incorporated under the conditions of vacuum cold and handle, reduce
Weight-loss ratio and rotting rate.
