Description

A kind of processing method of salty Eriocheir sinensis
Technical field
The present invention relates to the technical field of processing of aquatic products, particularly to the processing technique of a kind of Species of Crustacea, the specifically processing method of a kind of salty Eriocheir sinensis。
Background technology
Salty Eriocheir sinensis is the traditional characteristics food in Along The East Coast of Zhejiang And Jiangsu Provinces area, the Eriocheir sinensis classes such as the main swimming crab adopting fisherman to catch, take the female Eriocheir sinensis that its stout and strong cream is full, after the pickled salt brine such as saline flavoring agent, put in curing container and preserve, take out until needs are edible put with rice vinegar etc., both may be used for food and drink, meal can have been helped again。
But in the preparation method of traditional salty Eriocheir sinensis, often after catching direct salting and without any process, after salting also without the direct exposed placement of any packaging until edible, the salty Eriocheir sinensis product that such preparation method obtains is extremely unhygienic, bacterial content is significantly high, it is impossible to preserve for a long time, it is common that now do now sell, local sales, the aquatic products making original significantly high shelves lose due value, it is difficult to effectively open up market both domestic and external and have impact on the further of the sector and develop。
Application number is a kind of method improving salty Eriocheir sinensis preservation term and product quality disclosed in the patent of 95111581.2, and fresh Eriocheir sinensis is specifically soaked with disinfection by it in ClO 2 solution, followed by salting。But this method can only temporarily reduce the quantity of salty Eriocheir sinensis antibacterial, after waiting until antibacterial volatilization, its fresh-keeping effect also disappears therewith, and not killed antibacterial still may proceed to Fast-propagation in preserving process subsequently, of long duration be still difficult to avoid that rotten。
Although salty Eriocheir sinensis processing technique before has been carried out further improvement by the patent of application number 03151110.1, have employed the PROCESS FOR TREATMENT of vacuum packaging and cold sterilization, but it there is no progress in ensureing the fresh and local flavor of aquatic products, its processing mode adopted remains obvious deficiency for the requirement preserved for a long time simultaneously, also higher for the raw-material requirement of aquatic products, need to catch and swimming crab that stout and strong cream is full with fresh。
Summary of the invention
For the deficiency of traditional salty Eriocheir sinensis processing method, it is an object of the invention to provide a kind of select materials require low, adapt to permanent storage and transport needs and the beautiful new salty Eriocheir sinensis processing method of meat delicate flavour。
For achieving the above object, the salty Eriocheir sinensis processing method that the present invention adopts mainly comprises the following steps:
1) washing: the Eriocheir sinensis of the fresh Eriocheir sinensis caught or freezing is cleaned with clear water;
2) pre-preg: the Eriocheir sinensis after washing adopts the sea water mainly containing Folium Camelliae sinensis elite, glycine and salt thereof concentration mixed solution carry out pre-preg;
3) heating: Eriocheir sinensis after pre-preg is removed pre-preg mixed solution, puts into heating in the clear water of heat;
4) broken: the Eriocheir sinensis after heating to be crushed in disintegrating apparatus, until Eriocheir sinensis becomes atherosclerotic fluid;
5) stirring dipping: the atherosclerotic fluid after broken is sufficiently stirred for pickling sauce after mixing and impregnates;
6) encapsulation sterilizing: after the salty Eriocheir sinensis impregnated is encapsulated, carry out sterilization, obtain final product。
Preferably, in the washing of described step 1), clear water temperature is 2-5 DEG C, and washing time is 15-20min;
Preferably, described step 2) in pre-preg, Folium Camelliae sinensis elite is to be placed in hermetic container by postfermented tea and yellow wine with the ratio mix and blend of mass ratio 1:1, heat to 90 DEG C of after fermentation 2 days, subsequently by tunning with 90 DEG C of hot-water soaks of 30 times of quality of original material by water soluble ingredient dissolution, to obtain the solution containing Folium Camelliae sinensis elite;Described sea water concentration mixed solution is then concentrated by natural sea-water initially with ion exchange membrane, to obtain the brine concentration sea water concentrated solution at 12-15wt%, then by the Folium Camelliae sinensis elite solution prepared before and sea water concentrated solution 1:1 mixture by volume, add glycine and salt thereof so that calculating its content by glycine is 2-3wt%, the pH value regulating solution subsequently is 6-7, finally gives sea water concentration mixed solution;The time of described pre-preg is 10-15h, and temperature is 5-10 DEG C, and the part by weight that Eriocheir sinensis concentrates mixed solution with sea water is 1:2-3;
It is further preferred that described postfermented tea is the black brick in Hunan, described yellow wine is shao-hsing rice wine;
Preferably, described step 3) adds hankers, and clear water temperature is 85-90 DEG C, and heat time heating time is 1-2min;
Preferably, in described step 5) stirring dipping, the main component of described pickling sauce and part by weight thereof are, the part by weight of Shangri-la Gorge: Sal: Fructus Capsici: Glucose Liquid: white sugar: enriched soy sauce: pure water=5:5:0.5:5:2:20:50, pickling sauce and atherosclerotic fluid is 1:2-2.5;Described dip time is 1-2 days;
Preferably, in the encapsulation sterilizing of described step 6), what described encapsulation adopted is sterilization bag, and the temperature of described distillation is 110-115 DEG C, and distillation time is 15-20min。
Having the beneficial effect that of the inventive method
1) clean and employ the clear water of lower temperature and cleaned in advance so that the meat of Eriocheir sinensis is more fresh and tender, especially for freezing is waited for death Eriocheir sinensis, and it can be prevented effectively from the brittle further of crab meat fiber and hardening, provides guarantee for subsequent treatment。
2) pre-preg processes and have employed the pre-preg mixed solution of applicant's particular arrangement, the Folium Camelliae sinensis elite that wherein postfermented tea and yellow wine fermentation refine obtain can the fishy smell of effective place to go aquatic products, while can suppress the growth of antibacterial to a certain extent;And the interpolation of glycine and salt thereof can either effectively strengthen the water-retaining property of crab meat, it is prevented that the violent contraction that heating subsequently causes, and then improve dressing percentage, ensure that again enough taste and flavors;Containing substantial amounts of divalent metal ion in concentrated seawater, the effect of water-retaining property can either be played, crab meat can be softened again;Meanwhile, pre-preg process mixed solution is maintained at neutral or slightly biased acidity, it is also possible to improves water-retaining property, and improves taste and flavor。
3) it is broken more easy and abundant that the effect heated enables to subsequently, broken then ensure that the abundant smooth of dipping, while also make the packaging of salty Eriocheir sinensis and accumulating more convenient。
4) pickling sauce that dipping adopts is that applicant obtains through a large amount of trial summaries repeatedly, impregnates fully through appropriateness, can obtain taste excellence, it is easy to the salty Eriocheir sinensis product of preservation。
5) even if retort sterilisation enables to salty Eriocheir sinensis product and also is able to adapt to long accumulating in room temperature state。
