Abstract
The invention discloses a marinating material for marinating procambarus clarkii, which consists of crayfish, aniseed, cassia bark, pepper, rhizoma kaempferiae, fructus amomi, netmeg, fennel grass, clove, galangal, dried orange peel, lysimachia capillipes hance, lysimachia sikokiana and fennel seed in a certain proportion, and the step of marinating the procambarus clarkii by using the marinating material is as follows: A. fresh crayfish is taken as a raw material, cleaned, boiled in water, heated for one time and then fished out; B. boiling chicken or pork and auxiliary materials together to obtain soup, heating for the second time, and taking out the stewed shrimps; C. fishing out the shrimps subjected to marinating and putting the shrimps and the marinade into a vacuum packaging bag for vacuum sealing; D. heating by temperature-controlled water boiling heating mode, and rapidly cooling; E. and (3) freezing by using liquid nitrogen to instantly cool the product to a stable temperature, and then storing in a refrigerator. Provides the marinated fragrance, the marinade can inhibit the normal propagation and growth of bacteria, does not need to use artificial preservative additives, can kill pathogenic bacteria, and is beneficial to the health of human bodies and the preservation of the marinated shrimps.
Description
Technical Field
The invention belongs to the field of processing of marinated products, and particularly relates to a marinating material for marinating procambarus clarkii and a preparation method thereof.
Technical Field
In 2017, the breeding area of procambarus clarkia in China reaches 1200 ten thousand mu, the total output is nearly 113 million tons, the total value of social economy is about 2685 million yuan, and the procambarus clarkia becomes an important economic aquatic product in the middle and lower reaches of Yangtze river or even in the range of China, and is deeply loved by consumers due to delicious meat taste and rich nutrition. The processing modes of the method mainly comprise two processing modes, one processing mode is common braised prawn in the middle and lower reaches of the Yangtze river, the other processing mode is mainly spicy and hot crayfish in the northern area, and the spicy and hot crayfish is mainly spicy and hot in any processing mode, so that part of people who do not like eating the spicy and hot taste is excluded, and further development of the industry is restricted. The stomach, oral cavity and digestive system of eaters are easy to be uncomfortable, and the crayfish sauce stewed food can be only sold in the same processing day, and can be stored for more than 1 day under the refrigeration condition, so that the product hygiene exceeds the standard due to mass propagation of microorganisms. At present, frozen storage is adopted by aquatic product processing enterprises to prolong the shelf life of the crawfish sauce marinated food, however, the taste of the crawfish is deteriorated after the crawfish is frozen and thawed, the crawfish meat tissue becomes compact but not full, rough but not fresh and tender, and the commodity value of the crawfish is seriously influenced.
The invention discloses a Chinese patent with publication number CN108056411A, in particular to a processing method for removing fishy smell of instant crayfish, which uses a frying process to volatilize trimethylamine and remove fishy smell generated by metabolism and putrefaction of organic matters in the crayfish.
The invention patent of China with the publication number of CN107125642A discloses a processing technology of an instant marinated crayfish snack food, which uses a method of twice curing by oil stewing and marinating and a method of vacuum high-temperature high-pressure sterilization to prolong the shelf life.
The invention patent of China with publication number CN105394629A discloses a processing method of sauced crayfish stored at normal temperature, which uses the methods of oil braising, nitrogen gas filling packaging and electron beam sterilization to prolong the shelf life and keep the elasticity of the crayfish meat.
The invention discloses a Chinese patent with publication number CN108056411A, in particular to a processing method for removing fishy smell of instant crayfish, which uses a frying process to volatilize trimethylamine and remove fishy smell generated by metabolism and putrefaction of organic matters in the crayfish.
Marinating after frying can increase marinating time, flavor is not easy to enter, and frying weight loss is high. (the weight loss in frying is generally more than 15%, i.e. the weight of 1kg of shrimp after frying is not more than 850 g).
The invention patent of China with the publication number of CN107125642A discloses a processing technology of an instant marinated crayfish snack food, which uses a method of twice curing by oil stewing and marinating and a method of vacuum high-temperature high-pressure sterilization to prolong the shelf life.
The oil stewing and the marinating are carried out for the second time, because the oil stewing and the marinating are two different processing modes (the oil stewing temperature is about 150 ℃ generally, the marinating temperature is about 100 ℃), the weight loss is increased due to the second time of curing, when the vacuum high-temperature sterilization is carried out (the high-temperature sterilization temperature is about 120 ℃ generally), the main components of the vacuum packaging bag are PE and other materials, the temperature resistance range is (-40 ℃ -85 ℃), harmful substances to human bodies can be separated out or the packaging bag is damaged, and the product is influenced; the shelf life after conventional marinating does not generally exceed 1 month.
The invention patent of China with publication number CN105394629A discloses a processing method of sauced crayfish stored at normal temperature, which uses the methods of oil braising, nitrogen gas filling packaging and electron beam sterilization to prolong the shelf life and keep the elasticity of the crayfish meat.
Like CN107125642A, the marinating process after oil stewing has certain problems and is not adopted, the nitrogen-filled package can not fix the shrimps, so that the crayfish limbs fall off to influence the product, and the nitrogen-filled package can not lock the water in the shrimp meat, so that the meat loses water after long-term storage (more than 50 days), and the product loses value.
The two preparation processes of the three patents adopt two distinct processing modes of frying (oil) and marinating (water), and the following problems are mainly existed: 1. the frying loss is more, and the weight loss is 13-15% at the lowest through one-time frying generally; then, after stewing, the weight loss of water loss twice is more than 20 percent; 2. after frying, an oily hydrophobic layer is formed on the surface of the shrimps, so that the time consumption is long and the effect is poor when the shrimps are stewed for the second time; 3. and (3) marinating after frying, wherein frying oil is separated from marinade to influence the subsequent use of the marinade.

E. freezing by liquid nitrogen: freezing with liquid nitrogen to instantly cool the product to-40 deg.C, stabilizing the temperature, and storing in-18 deg.C refrigerator.
Wherein the preparation method of the marinade in the step C comprises the following steps: calculated by the mass of 4 parts of water, 0.5 part of auxiliary material is added to prepare the water-soluble paint, and the auxiliary material is prepared according to the following parts by weight: 55 parts of aniseed, 50 parts of cassia bark, 30 parts of pepper, 45 parts of rhizoma kaempferiae, 50 parts of fructus amomi, 50 parts of nutmeg, 50 parts of fennel grass, 25 parts of clove, 25 parts of galangal, 30 parts of dried orange peel, 25 parts of lysimachia foenum-graecum hance, 40 parts of lysimachia foenum-graecum and 25 parts of fennel seed.
Further, the mass ratio of the marinade to the shrimps is 0.5:1, adding into a vacuum packaging bag.
In the marinating process of the present invention, the two steps of step A, B function to reduce water loss by the two-cook process, with about 7% water loss on the first heat and about 5% water loss on the second heat, for a total water loss of about 12%. The loss of control moisture is on the one hand for the profit of processing product, and water loss is more, and the total weight loss of product is more promptly, is unfavorable for the product total price, and on the other hand, the loss moisture is mostly the moisture in the meat, loses too much, will influence the taste to a certain extent, or if the meat is too tough to chew, or the meat loses elasticity. The existing marinating mode generally loses about 25 percent of water.
And the step D is that the pasteurization is applied to the processing of the procambarus clarkia, and the temperature range and the time range of the pasteurization are fixed to an accurate value through practice and grope. The existing pasteurization method has larger heating temperature and time range, and is not beneficial to condition control in actual production.
The step E has the effect of quick freezing, so that on one hand, the shrimps quickly pass through the ice crystal formation period, the water in the cells is not lost to influence the mouthfeel when the shrimps are stored for a long time, and the original mouthfeel can be kept when the shrimps are heated again before eating; on the other hand, cold stimulation is formed on part of the living microorganisms, and the shelf life can be prolonged. Under the existing conditions, the quality guarantee period of the marinated shrimps is about 30 days generally under the condition of not adding an antiseptic additive.
Compared with the prior art, the invention has the following advantages and effects:
(1) the raw materials used by the marinade of the invention are aniseed, nutmeg, fennel grass, fennel seed and other ingredients which are composed according to a certain proportion. The main raw materials are supplemented with corresponding ingredients, so that the shrimp meat has the best color and taste, and the yield of the product is highest (the water loss is minimum). The main progress is as follows: 1. the shrimp meat has ruddy color, salty and fragrant taste, smooth and tender mouthfeel, is easily accepted by more people, and has low water loss rate 2. after marinating, the water loss rate is 12 percent and is far lower than about 25 percent of that of the traditional method. 3. After the marinating is finished, the shrimps have no peculiar fishy smell of aquatic products, only have the fragrance of spices, and have good sense of smell. 4. The used spices have the auxiliary effects of strengthening the functions of the spleen and the stomach, promoting digestion and absorption and strengthening the immunity, and are beneficial to the health of the body;
(2) the marinating method adopts a twice heating mode, moisture can be locked after the first heating, the moisture loss in the second heating process is small, the weight loss of the processed procambarus clarkii is about 12%, the moisture loss is about 7% after the first heating, and the moisture loss is about 5% after the second heating. The loss of water is controlled for the profit of the processed product, on one hand, the loss is more, namely, the loss of the total weight of the product is more, which is not beneficial to the profit, on the other hand, the loss of water is mostly the water in the meat, and the loss is too much, which will affect the taste, or if the meat is too tough and difficult to chew, or the meat loses elasticity;
(3) the high-temperature and low-temperature quick-freezing alternative sterilization of the invention has two main effects on the taste, on one hand, the moisture is reasonably controlled, such as the low moisture content of the spiced beef, the possibility of tooth filling (the shrimp cannot fill the teeth due to the muscle fiber characteristic), the chewing difficulty and the like, on the other hand, the fat content can be controlled, the low fat content has stiff taste, and the high fat content has no problem due to the muscle fiber characteristic. Besides the addition of seasonings, the taste is mainly influenced by free fatty acid and free amino acid, on one hand, Maillard reaction in which the fatty acid participates is a main factor for forming meat taste, and on the other hand, the free amino acid, particularly glutamic acid and the like are main flavor amino acids and are main sources of delicate flavor. Excessive water loss of meat quality can be caused by overhigh temperature and overlong time (the specific principle is not clear, but the long-time high-temperature heating sterilization can influence most of meat quality, and the main component of a common packaging bag is PE which cannot resist high-temperature heating (below 85));
(4) according to the invention, the high-temperature and low-temperature quick-freezing alternate sterilization can kill pathogenic bacteria and most non-pathogenic bacteria, is beneficial to human health and preservation of brine shrimps, the main pathogenic bacteria mainly killed are escherichia coli, salmonella, staphylococcus aureus and the like, the non-pathogenic bacteria are mainly bifidobacteria, lactic acid bacteria and the like, and the detection indexes refer to GB 4789-; in addition, the marinade can inhibit the normal reproduction and growth of most bacteria, and an artificial preservative additive is not needed;
(5) the marinating material disclosed by the invention is fragrant in smell, and the marinated shrimps are ruddy in color, mellow in smell, moderate in taste and not spicy in taste, so that the marinating material is particularly suitable for people who do not like spicy taste and do not like light taste;
(6) the invention has long storage period, and the taste and flavor of the product are not changed after the product is stored for 90 days under the condition of continuous cold chain. The mouthfeel changes are mainly as follows: on the one hand, the meat quality is too compact or rough due to water loss, and thus the commercial value is lost, and on the other hand, the meat is rotten due to the propagation of microorganisms during storage at normal temperature. The original taste is lost due to the change of the taste. Over 30 days, water loss easily results in rough meat and loss of elasticity.
