Description

A kind of processing method of high-moisture stripped tuna goods
Technical field
The present invention relates to technical field of aquatic product processing, be specifically related to a kind of processing method of high-moisture stripped tuna goods.
Background technology
Stripped tuna belongs to Perciformes mackerel section stripped tuna and belongs to, and is important oceanodromous migration fish, and be distributed widely in the Pacific Ocean, the Atlantic Ocean, the torrid zone of the Indian Ocean, subtropical zone and marine site, subfrigid zone, China East Sea and the South Sea also can be caught in a large number.Stripped tuna delicious meat, nutritious, stripped tuna contains rich in protein, superior amino acid ligand ratio and the polyunsaturated fatty acid of the multiple high bioactivity such as DHA, EPA, has the function promoting brain development, effectively prevention cardiovascular and cerebrovascular disease.Processing raw fish and making stripped tuna can are the major consumers modes of stripped tuna, and be mainly used in processing " oceanic bonito joint " Japanese stripped tuna, being dug into wooden fish flower time edible, is the flavouring of japanese traditional, also can be made into raw fish and eats.
At present, mainly concentrate on fishery resources aspect both at home and abroad to the report of stripped tuna, the local flavor research report about stripped tuna and products thereof is less.Chinese patent notification number CN104621618A, May 20 2015 day for announcing, disclose a kind of processing method of instant tunny fillet, cut into slices after comprising pretreatment of raw material, use baste seasoning 3 ~ 5h again, fillet after seasoning are spread out and toast 6 ~ 8h in the baking ovens of 40 ~ 45 DEG C, 20 ~ 25% of fillet weight is reached to moisture, then use infrared baking machine at 160 ~ 180 DEG C of baking 5 ~ 8min, finally by the dehydration of fillet heated-air drying to moisture between 15 ~ 17%, be cooled to inflated with nitrogen packed products after room temperature.This invention preparation method is easy to operate, and obtained instant fillet tasty mouthfeel, improves the commercial value of tuna, but the fillet moisture that this invention obtains is low, poor water retention property.
Summary of the invention
The fillet moisture that the object of the invention is to solve prior art obtained is low, and the problem of poor water retention property, provides a kind of moisture high and the stripped tuna product processing method of good water-retaining property.
Concrete technical scheme of the present invention is: a kind of processing method of high-moisture stripped tuna goods, comprises the steps:
(1) pretreatment: internal organ are removed in raw material peeling of decaptitating, and clean up rear section;
(2) de-raw meat: by the fillet cut, put into the water of 40 ~ 45 DEG C, the weight ratio of fillet and water is 1:1 ~ 1:1.5, adds and accounts for the salt of fillet weight 2 ~ 5% and the acetic acid of 0.5 ~ 1%, after stirring evenly, soaks 25 ~ 40min;
(3) bake: the fillet after step (2) being soaked use microwave baking;
(4) vacuum seasoning: the fillet after baking are put into vacuum seasoning pot, adds the baste of fillet weight 1.5 ~ 3 times, with vavuum pump, the air pressure of seasoning pot is extracted into-0.06Mpa, keeps 10 ~ 20min;
(5) dry: the fillet after vacuum seasoning are carried out heated-air drying, and control temperature is at 40 ~ 50 DEG C, until fillet water content is 24 ~ 28%;
(6) sterilization: by dried fillet in high-pressure sterilizing pot in 120 DEG C of sterilizing 15 ~ 20min, then load in bag and vacuumize.
Microwave baking is using heating object material itself as heater, and microwave instantaneously can be deep into internal batch, material inside and outside is heated simultaneously, does not need heat transfer, is exceedingly fast, substantially reduces the heat time so heat up.Heating using microwave speed is fast, and internal batch air themperature sharply rises, and because mass transfer velocity is slow, heated gas is in height pressured state, and has the trend of expansion, and when reaching certain pressure, material will expand, thus obtained bulk, soft food.This fuel factor be rapidly heated of microwave also has the effect of sterilization, and simultaneously the non-thermal effect of microwave can make organism internal protein and physiological activator morph and devitalization or death reach the effect of sterilization.The present invention adopts microwave baking stripped tuna fillet, and the processing time is short, and obtained fillet are soft, agreeable to the taste, easily chew.
As preferably, the power of described step (3) microwave baking is 700 ~ 1000W, bakes time 4 ~ 10min.Power and the time that bakes of microwave affect very large on the mouthfeel of fillet, power is excessive, bakes of long duration, and obtained fillet mouthfeel is stiff, and microwave power is little, bakes the time short, and obtained fillet are soft not, are difficult to chew.
As preferably, in described step (4), the component of baste and mass fraction are: soy sauce 19.4 ~ 19.9%, white granulated sugar 8.2 ~ 8.8%, cooking wine 10.5 ~ 10.8%, monosodium glutamate 0.3 ~ 0.5%, ginger 1.8 ~ 2.4%, aloe extract 4.6 ~ 10.8%, and all the other are water.The present invention is in seasoning process, adopt vacuum seasoning, shorten the time of penetration of baste, local flavor infiltration completely, obtained stripped tuna fillet taste is finer and smoother, with the addition of aloe extract simultaneously, can improve the water-retaining property of fillet in baste, make fillet after long-time storage, still containing higher moisture.
As preferably, the extracting method of described aloe extract is:
(1) Fresh leaf of aloe thimerosal is washed, then with water cleaning, obtain aseptic Chinese aloe leaf;
(2), after Chinese aloe leaf peeling, Aloe mesophyll is smashed to pieces, homogenate, obtain Aloe gel serofluid;
(3) by Aloe gel serofluid and absolute ethyl alcohol by volume 1:3 ~ 1:7 mix, adopt ultrasonic wave to extract to obtain extract;
(4) extracting liquid filtering, Vacuum Concentration, freeze drying are obtained aloe extract.
As preferably, in the extracting method of described aloe extract, ultrasonic wave extraction conditions is temperature 20 ~ 40 DEG C, time 40 ~ 60min, and ultrasonic frequency is 20 ~ 40kHz, and power is 400 ~ 1000W.
The invention has the beneficial effects as follows: (1) the present invention adopts vacuum flavoring technology, shortens the time of penetration of baste, completely, obtained stripped tuna fillet taste is finer and smoother in local flavor infiltration; (2) with the addition of aloe extract in baste of the present invention, the water-retaining property of stripped tuna fillet can be improved, make fillet keep comparatively high-moisture; (3) the present invention adopts microwave baking, shortens the time of baking, and obtained fillet are soft, mouthfeel is good.
