Summary of the invention
Technical problem to be solved by this invention provides a kind of packed Braised soft-shelled turtle in brown sauce, and the preparation method of this packed Braised soft-shelled turtle in brown sauce is provided, being difficult to of requiring this preparation method to solve to exist in the packed Braised soft-shelled turtle in brown sauce goods process vacuumize and sterilization after the too soft mashed problem of meat.
For solving the problems of the technologies described above, the invention provides a kind of packed Braised soft-shelled turtle in brown sauce, the preparation method of this packed Braised soft-shelled turtle in brown sauce is characterised in that: comprise the step of the packed soft-shelled turtle after vacuumizing being carried out the back-pressure sterilization.
For the purpose of the brief description problem, below the preparation method of a kind of packed Braised soft-shelled turtle in brown sauce of the present invention is all abbreviated as this method.
Because the soft-shelled turtle meat is tenderer, normal high temperature sterilization can make the soft-shelled turtle meat too soft mashed, loses original mouthfeel.This method is carried out the back-pressure sterilization to the packed soft-shelled turtle after vacuumizing, and significantly reduces the time of staying of soft-shelled turtle under hot conditions, makes packed soft-shelled turtle meat can softly not rot, and keeps original mouthfeel to greatest extent.
As the optimization of this method, its concrete preparation process is:
(1) soft-shelled turtle preliminary treatment: the soft-shelled turtle piece after fried is mixed with salt, sugar, made oily soft-shelled turtle piece and salt, sugar mixture;
(2) baste preparing gel: add edible gelatin in baste, be heated to 40-45 ℃ under stirring, be cooled to room temperature after the edible gelatin dissolving, form the baste gel, it is standby to make gel piece;
(3) vacuumize: will cross oily soft-shelled turtle piece and salt, sugar mixture 80-85 weight portion, baste gel piece 15-20 weight portion is put into anti-retort pouch, and seal after vacuumizing;
(4) back-pressure sterilization: the anti-retort pouch after will sealing carries out the back-pressure sterilization.
Gelatin is the peptide molecule polymeric material, is the multistage hydrolysate of collagen, in industrial circle extensive application such as food, medicine.Edible gelatin is a kind of food additives, and higher nutritive value is arranged, and imbibition is soluble in warm water to self 5-10 times in cold water, and cooling forms gel, and is molten between 35-40 ℃.This method soup juice (water, sauce for braising, flavoring) that packed Braised soft-shelled turtle in brown sauce is required adopts edible gelatin to carry out gelation and handles, pack simultaneously with the mixture of crossing oily soft-shelled turtle piece, salt, sugar, can guarantee that soup juice is not drawn out of when vacuumizing, the shortening process of meat is finished simultaneously in follow-up sterilization workshop section, reduces the heat time heating time of meat products.Therefore, the described vacuum pumping method of this method both can guarantee that vacuum-packed soft-shelled turtle goods possess and contain soup juice in the packing, can make the soft-shelled turtle goods after the sterilization possess certain chewability again.
Have before described soft-shelled turtle is fried butcher, go to remove from office the shape thing, remove internal organ, step that stripping and slicing, cleaning control are done.
Described baste is made up of the material of following parts by weight: anistree 1-2, cassia bark 1-2, cardamom 1-2, root of Dahurain angelica 1-2, lemon-grass 1-2, green onion 3-5, ginger 3-5, sauce for braising 24-25, water 49-60.Spice in the baste, except the function that possesses common seasoning, wherein anise, cassia bark, cardamom, the root of Dahurain angelica, lemon-grass possess the effect of further covering soft-shelled turtle fishy smell and increasing the soft-shelled turtle delicate flavour, and then promote the local flavor of product.
Edible gelatin 5-6 weight portion is arranged in the baste gel of described per 100 parts by weight of this method.
Described gel piece size is 1cm * 1cm * 1cm.The excessive heating for dissolving that then is difficult for of gel piece, waste heating power.
Described vacuumizing at vacuum packing machine carried out.
As the further optimization of this method, carry out in the described back-pressure sterilization counter pressure retort, the back-pressure sterilization conditions is 121 ℃ of sterilization temperatures, sterilizing time 15 minutes, inject cold water directly forced to cool off 3 minutes.
Adopting the back-pressure disinfection equipment, is that heat medium carries out high-temperature sterilization to product to feed saturated vapor, implements the back-pressure operation with additional compressed air, and the cold water that reinjects is directly forced cooling, can significantly reduce the time of staying of soft-shelled turtle under hot conditions.
On the basis of above-mentioned basic technical scheme, following further technical scheme can be arranged: can in baste gel manufacturing process, not use sauce for braising, change the ratio of oily soft-shelled turtle piece and salt, sugar mixture and baste gel piece, be made into clear soup juice type soft-shelled turtle product.
This method has following advantage:
(1) solve the vacuum-packed goods of Braised soft-shelled turtle in brown sauce and added man-hour, because soup juice exists, when vacuumizing, the difficult problem that the soup juice in the bag is extracted out simultaneously;
(2) owing to need soft-shelled turtle and the baste gel of processing to pack simultaneously, adopt the back-pressure sterilization technology to carry out sterilization, the shortening process of meat is finished simultaneously in follow-up back-pressure sterilization workshop section, reduces the heat time heating time of soft-shelled turtle goods, solves the too soft mashed shortcoming of meat that the soft-shelled turtle long-time heating causes;
(3) adopt soft-shelled turtle to cross the method for removing fishy smell that oil and spice are further covered soft-shelled turtle fishy smell, do not have fishy smell substantially except the soft-shelled turtle after the raw meat, can satisfy normal edible demand;
(4) this method utilizes original production equipment to produce, and need not increase miscellaneous equipment newly, saves manually, and cost is low, and energy consumption is little, and is easy and simple to handle, and suitability for industrialized production is implemented easily.
