Description
Technical field
The invention belongs to edible fungus fresh-keeping technical field, and in particular to a kind of natural fresh-keeping method of hickory chick.
Background technology
Hickory chick Morchella esculenta (L.) Pers is edible fungus famous in sac fungus, is belonged in classification
It is rich in Ascomycotina (As-comycotina), discomycete (Discomycetes), Pezizale (Pezizales), its nutrition
Richness, amino acid, fat, carbohydrate, mineral element, trace element and vitamin are rich in fructification, there is beneficial stomach, disappear
Change help food, phlegm-eliminiating and qi-regulating, kidney tonifying, establishing-Yang, cerebrum tonifying, refresh oneself, reducing blood lipid, raising immunologic function, antifatigue, radioresistance, it is antitumor,
Whitening etc. acts on, and has broad application prospects in fields such as food, medicine, cosmetics.But hickory chick water content is high, tissue is non-
Often delicate, cap surface does not have obvious protection structure, adopts rear 1-2d under normal temperature, and the moisture inside thalline will a large amount of Evapotranspirations
Lose, cap and lamella start rupture of membranes, parachute-opening, dehydration, atrophy, brown stain or even rotted, and stem elongation, commodity value, which declines, even loses
Lose.Being overstock once hickory chick caused by after adopting causes quality decline so as to not reach outlet and processing request, can bring about huge
Economic loss.Therefore, the post-harvest fresh-keeping problem of hickory chick is resolved, extends its transport and shelf-life, is hickory chick industry
Change and develop extremely urgent major issue.
Application number 201610851846.5 discloses a kind of air regulating fresh-keeping method for significantly extending hickory chick freshness date, this method
The step of it is as follows：(1) pre-process：Hickory chick is cleaned after drying, sprays pretreating agent, the pretreating agent by weight,
It is made up of following component：Boric acid 2-5 parts, ascorbic acid 3-6 parts, sodium acetate 1-2 parts, iron sulfite 1-2 parts, deionized water 1000
Part；(2) controlled atmosphere preservation is carried out to pretreated hickory chick, the condition of the controlled atmosphere preservation is：Oxygen volume content is 0.7-
0.8%, carbon dioxide volume content is 10-12%, and remaining is nitrogen, and humid control is in 80-90%.The achievable normal temperature of the present invention
Under (20-25 DEG C) be up to the fresh-keeping effect of 21 days, after preservation 21 days, the weight-loss ratio of hickory chick is not higher than 3%, soluble solid
Content is maintained at 6% or so.Although this method extends the preservation time of hickory chick, but contain chemical synthesis in pretreating agent
Medicine, potential danger can be produced to the health of consumer；And coating-film fresh-keeping and controlled atmosphere, complex operation need to be combined.
The content of the invention
For the above-mentioned problems in the prior art, it is an object of the invention to provide a kind of natural fresh-keeping of hickory chick
Method, to only by extending the fresh-keeping cycle of hickory chick, day in the method for hickory chick surface coating Essential Oil of Radix Angelicae Dahuricae extract solution
So safety, it is easy to operate, laid the foundation for the industrialized development of hickory chick.
For achieving the above object, the technical solution adopted by the present invention is as follows：
A kind of natural fresh-keeping method of hickory chick, methods described step are：Select thalline complete, non-parachute-opening, no disease and pests harm
Basically identical hickory chick is pre-processed with machinery wound, size, sprays Essential Oil of Radix Angelicae Dahuricae extract solution, after drying, loads packaging
Bag, 2-6 DEG C of storage.
Further, the concentration of the Essential Oil of Radix Angelicae Dahuricae extract solution is 0.8-5.3%.
Further, the concentration of the Essential Oil of Radix Angelicae Dahuricae extract solution is 1.2-4.6%.
Further, the method for the pretreatment is：Pin mud is removed, is gently rinsed with sterilized water, after naturally dry, in 680-
2.8-3.2h is handled under 730Pa, 1.2-1.5 DEG C of environmental conditions.
Further, the method for the pretreatment is：The ozone for being 3.2-3.8g/h with concentration by the hickory chick of select
Generator handles 16-20min.
Further, the method for the pretreatment is：The hickory chick of select is placed in precooling 10- in 2-3 DEG C of freezer
12h。
Further, the method for the pretreatment is：With 200-300 μ W/cm2Ultraviolet rotary radiation 40-60min.
Further, the packaging bag is polyethylene packaging bag, polyvinyl chloride packaging bag or polyvinylidene chloride packaging bag.
The root of Dahurain angelica (Angelicae dahuricae) also known as Lemonfragrant Angelica Root, it is the umbellate form section plant root of Dahurain angelica (Angelica
Dahurica (Fisch.ex H offm.) Benth.etH ook.f.) dry root.One of its main component is volatile oil, right
Escherichia coli, dysentery Song Shi bacillus, typhoid bacillus, paratyphosum Bacterium, Pseudomonas aeruginosa, proteus, comma bacillus, M. tuberculosis
Bacillus, staphylococcus aureus etc. have inhibitory action.The present invention sprays Essential Oil of Radix Angelicae Dahuricae in hickory chick surface, can reduce sheep
The weight-loss ratio of tripe bacterium storage period, its hardness is preferably kept, and then extend the fresh-keeping cycle of hickory chick.
Compared with prior art, beneficial effects of the present invention are：Can reduce hickory chick storage period weight-loss ratio, preferably
Its hardness is kept, extends the fresh-keeping cycle of hickory chick, natural safety is easy to operate, and base is established for the industrialized development of hickory chick
Plinth.

1. weight-loss ratio
Weight method, weightlessness is calculated in the mass change of storage period according to embodiment 1-5, blank control group CK hickory chicks
Rate, as a result see Fig. 1.
The mass loss of hickory chick is mainly derived from water, and the moisture size and existing way of hickory chick not only affect
Its edible quality, and affect its keeping quality and disease resistance.
It is can be seen that from Fig. 1 results during Essential Oil of Radix Angelicae Dahuricae coating-film fresh-keeping refrigerates, the moisture of hickory chick is in totally
The moisture decrease speed of now continuous downward trend, wherein blank control group is obviously higher than embodiment 1-5,0-15 skies
White control group weightlessness is shallower, and weight-loss ratio reaches 7.79% within the 25th day, and the 25th day weight-loss ratio of embodiment 1-5 is below
3.65%, and embodiment 4-5 weight-loss ratio is better than embodiment 1-3 weight-loss ratio.
2. hardness
Hardometer is determined, and embodiment 1-5, blank control group CK hickory chicks are cut into epidermis, then vertically put hardometer
In its surface, pressure head is pressed into sample in the effect one of uniform force, the hardness number using the reading of now pointer as sample, as a result
See Fig. 2.
Hardness is also one of important indicator for reflecting fresh-keeping effect, figure it is seen that the hickory chick as blank control
Hardness decline it is very fast, it is only gradually slow to downward trend after 25 days, and the hardness for passing through the hickory chick of Essential Oil of Radix Angelicae Dahuricae processing becomes
Change is significantly better than control sample, and hardness is still greater than 7.36 × 10 within the 25th day6Pa, and the hardness of embodiment 4-5 hickory chicks is better than implementation
Example 1-3.
