Summary of the invention
Goal of the invention of the present invention provides a kind of Tilapia mossambica product, makes it have mouthfeel and the taste of bright Tilapia mossambica, and does not lose too much nutrition, and the method for this product of preparation is provided simultaneously.
A kind of preparation method of freezing bread Tilapia mossambica fish bar of the present invention, wherein, described method comprises the steps: that step successively is: preparation Tilapia mossambica fish bar; Wrap up in powder; Wrap up in slurry; Wrap up in breadcrumbs; Quick-frozen; Weigh, packing is stored, metal detection, and the sign inspection, vanning is stored carton and is checked and accepted, refrigeration.
In detail and concrete grammar following:
1. after Tilapia mossambica being cleaned out, handle the adult fish bar;
2. on the fish bar, wrap up in powder;
3. on the fish bar, wrap up in slurry;
4. on the fish bar, wrap up in breadcrumbs;
5. quick-frozen;
6. detect the back packing.
The method of handling the adult fish bar is: raw material is checked and accepted; The whole piece fish is cleaned, and scales, goes internal organ; Fish appearance and inner cleaning; With the fillet of well cutting, wherein sheet is of a size of thickness 0.5mm to 1cm after hacking, an edge lengths 3-15cm, another side 1-7cm; Clean; Pickle, the balance moulding, quick-frozen, cutting cuts into strip with fillet, and wherein, the length of strip is 2-15cm; The cross section is of a size of: long limit and broadside are 0.5mm to 1cm;
Step successively is: wrap up in powder; Wrap up in slurry; Wrap up in breadcrumbs; Quick-frozen; Weigh, packing is stored, metal detection, and the sign inspection, vanning is stored carton and is checked and accepted, refrigeration.
The treatment step of above-mentioned step 1 comprises: raw material is checked and accepted, and cleans, and scales, goes internal organ, cleans, and hacks, and cleans.
Can also comprise before the above-mentioned step 2 and pickling, the balance moulding, quick-frozen, wherein, said pickling is to pickle with conventional method with conventional flavouring.
Wrap up in the above-mentioned step 2 before the step of powder; On the fish bar, smear cryoprotector; The composition and the proportioning thereof of said cryoprotector are following: salt 1-2 gram, vitamin C 0.1-0.5 gram, lysine 3-7 gram, honey 5-10 gram, edible alcohol 1-2 gram, water (preferred distilled water) 15-30 gram.This is an inventive point of the present invention; Because Tilapia mossambica fish bar can lose moisture content and the mouthfeel that influences protein in the flesh of fish after freezing; Passed through inventor's test of many times; Obtained combination disclosed by the invention; Guarantee Tilapia mossambica fish bar after handling through cryoprotector of the present invention, its freezing patience is significantly improved, and protein denaturation reduces; Water retention property improves, and it is good that fresh and alive flavor taste keeps.Cryoprotector of the present invention when in use, optimum temperature is 3-15 degree centigrade, soak time is 10 minutes-2 hours.
The amygdalin that can also comprise the 1-2 gram in the above-mentioned cryoprotector.
Wrap up in the above-mentioned step 2 before the step of powder; On the fish bar, smear cryoprotector; The composition and the proportion optimization thereof of said cryoprotector are following: salt 1.5 grams, vitamin C 0.3 gram, lysine 5 grams, honey 7 grams, edible alcohol 1.5 grams, water (preferred distilled water) 20 grams.
Wrap up in the above-mentioned step 2 in the step of powder, wrapping up in powder can be selected from: wheat flour, cornstarch or potato starch, preferred cornstarch.
Wrap up in the above-mentioned step 3 in the step of slurry, wrap up in the starch composition and the weight portion ratio is: wheat flour, sugar, yeast, salt, weight portion ratio are 100: 15-20: 2-2.5: 3-7.
Method of freezing in the above-mentioned step 5 is following :-5 to-8 degrees centigrade held 5-10 minute, immediately-15 to-18 degrees centigrade held 5-10 minute, put into immediately then-30--35 degree centigrade following 15-30 minute, put into-20 degrees centigrade then and preserve down.This method is another inventive point of the present invention, because process inventor's test of many times finds that the meat of Tilapia mossambica is freezing under above-mentioned method; Protein than after the direct quick-frozen is good; And after thawing, the moisture content of protein is sufficient, and mouthfeel class Sihe is near fresh Tilapia mossambica meat cutlet.Product of the present invention is a Tilapia mossambica fish bar, so freezing method is different with the fillet of bulk, if adopt the freezing method of conventional bulk fillet, can cause the moisture content in the meat to run off, and product eats the mouthfeel variation.
The invention effect:
The rank of result's to be product of the present invention all reached on young slippery, hardness, aftertaste, fragrance, 5 indexs of whole sensation high-quality, product of the present invention is more than 6 months in the shelf-life of freezing state.
