Keep the processing and storage method of Dokou roasted chicken traditional properties
Technical field
The invention belongs to food storage field, be specifically related to the method for the cooling disposal options of roast chicken, transporting mode and fresh-keeping.
Background technology
Dokou roasted chicken is the famous traditional sauce spiced and stewed food of China, carries out production and processing by traditional formula, does not add the materials such as any anticorrisive agent, water-loss reducer, and product nutrient safe, handsome in appearance, fragrance is unique strong.Unique moulding, batching and traditional handicraft have given Dokou roasted chicken special local flavor and mouthfeel, but because it is nutritious, are easy to be subject to microbial contamination and go bad.Because Dokou roasted chicken technological parameter is fuzzy, storage technique falls behind, cause that the product shelf phase is short, quality safety is unstable, sell radius less, have a strong impact on the industrialization process of China's traditional product, restrict further developing of China's traditional food, become the technical bottleneck of its modern production of restriction.
It is higher that Dokou roasted chicken heating halogen boils rear product temperature, needs cooling processing, and the conventional type of cooling is platform-type air-cooled at present, and microbial contamination is very serious, has greatly limited sale radius and the storage method of product, and shelf life is very short only has 1-3 days; Because microbial contamination is serious, the conventional manner of packing one of enterprise is vacuum packaging high-temperature sterilization, and the product of which packaging does not only have the distinctive local flavor of Dokou roasted chicken, has affected to a certain extent mouthfeel, has destroyed especially original moulding attractive in appearance aspect moulding; The 2nd, the fresh-keeping mode of adding or spraying anticorrisive agent, water-loss reducer, which has been destroyed original traditional properties and quality to a certain extent, is difficult to keep original traditional properties and security.
Controlled atmospheric packing, as a kind of novel manner of packing, meets natural, non-additive consumption idea, can keep Shelf-life under the original local flavor prerequisite of roast chicken, realizes the storage of traditional product industrialization safe, has good practical value and economic worth.At present, controlled atmospheric packing is used in vegetables or fresh meat fresh-keeping, and in meat, conventional controlled atmospheric packing gas is oxygen (O
2), carbon dioxide (CO
2) and nitrogen (N
2).O
2can keep the redness of fresh meat, but O
2have and be beneficial to fatty acid oxidation and become sour.CO
2be a kind of stable compound, colourless, tasteless, it can bacteria growing inhibiting.N
2stable in properties, color and luster and microorganism on meat do not affect, and can keep packing full.Protein in fresh meat is more conducive to microbial growth breeding after Overheating Treatment, and Dokou roasted chicken is the product after fried shortening, as easy as rolling off a logly in cooling procedure suffers microbial contamination, and the growth of microorganism speed of pollution is very fast, and fresh-keeping difficulty is very large.Meanwhile, high CO
2controlled atmospheric packing is along with storage time extends, the CO of packaging
2gas is easily absorbed and packaging material is subsided, impact packaging effect; And low CO
2gas is difficult to play fresh-keeping object.
Therefore, after Dokou roasted chicken halogen boils, how to dispose with cooling, how to preserve and to pack, can ensure traditional design, the traditional properties of Dokou roasted chicken, reduce again or avoid microbial contamination, Shelf-life and ensure that security is a difficult problem.
Summary of the invention
The object of this invention is to provide a kind of processing processing and manner of packing of Dokou roasted chicken, can keep Shelf-life and guarantee Product Safety under roast chicken traditional properties prerequisite.
Technical scheme of the present invention is as follows: a kind of processing and storage method that keeps Dokou roasted chicken traditional properties, and its step is as follows:
(1) the product sterile gauze boiling through eight kinds of batchings of traditional Dokou roasted chicken and long-used soup halogen 40-120 minute is covered and be placed on the putting on dish of cooling shelf, cooling shelf is transported in cooling chamber, in described cooling chamber, be provided with air cleaner, adopt nature cold wind to be cooled to normal temperature;
(2) cooled Dokou roasted chicken packs in Air Proof Packing mounted box, utilizes gas-control packing device to be filled with CO in packing box

255~85% of cumulative volume, is then placed in packaged roast chicken under 4-20 DEG C of environment and preserves.
Described Dokou roasted chicken before live chickens are checked and accepted, kill quarantine, electricity fiber crops, slaughter, bloodletting, soak scalding for removing the hair of materia medica, the chamber of cutting open the chest out, rebuild body surface, rinse moulding, paint friedly, add chicken 100 kg, fructus amomi 15.0kg according to the traditional sauce halogen technology in road junction, dried orange peel 30kg, root of Dahurain angelica 90kg, cloves 3.0kg, cardamom 15kg, Chinese cassia tree 90.0kg, tsaoko 30 kg, the eight taste seasoning matter such as galingal 90kg, and be equipped with long-used soup, halogen boils and is placed on cooling shelf, is transported in cooling chamber.Live chickens require chest abdomen length and width, two legs are stout and strong, healthy anosis.
The packaging film of described packing box adopts the transparent material of sealing, upper inflation 2.0 in packing box, lower inflation 1.0.
Described cooling shelf comprises pedestal and montant, between montant between peg graft be provided with 1-3 layer grid, grid is provided with puts dish.
The intermediate projections of described grid, each montant is hollow, and described base bottom is provided with back taper drip tray, and drip tray middle is provided with osculum.
Described cooling shelf is stainless steel material.Described cooling shelf bottom is provided with roller.
The present invention adds dried orange peel, Chinese cassia tree, beans bandit by traditional Dokou roasted chicken sauce halogen technology, cloves, the root of Dahurain angelica, fructus amomi, tsaoko, the eight taste seasoning matter such as galingal, and being equipped with long-used soup, after halogen boils cooled product sterile gauze and covers, adopting cooling shelf to be transported to chilling room, to carry out nature cooling, not only avoid microbial contamination, and reduce energy consumption and drying loss; Grid and the intermediate projections of putting dish, base bottom is provided with taper drip tray, and drip tray middle is provided with osculum, and grid and the area of putting dish are less than the area of drip tray, Dokou roasted chicken cooling go out moisture flow into back taper drip tray from grid surrounding, discharge by osculum.Below cooling shelf base, have roller, structure is firm, is convenient to move, and puts dish easy to clean, can effectively prevent microbial contamination.
In conjunction with CO
