A kind of compound anti-oxidation technology keeps the method that green grass or young crops accounts for fillet product property
Technical field
The invention belongs to food processing storage technique field, be specifically related to a kind of compound anti-oxidation technology and keep green grass or young crops
The method accounting for fillet product property.
Background technology
Qing Zhanyushu mackerel section, chub mackerel belongs to.For oceanodromous migration epipelagic fish, swimming power is strong, and speed is big.Distribution
In west of pacific ocean.It is all produced in coastal waters.This kind of fish distribution is wide, growth is fast, yield is high, economic worth quite
High, oppress every hectogram containing 21.4 grams of protein, lipase 37 .4 gram, meat is solid, also can dry in the sun in addition to eating raw
With make canned food, its liver can refine cod-liver oil.Green grass or young crops accounts for the fish flesh of fish and is used as medicine, and meat has the function of strengthening by means of tonics.Cure mainly
The diseases such as gastroenteropathy, pulmonary tuberculosis are deficient, neurasthenia.But must eat fresh, (dead once damp proof insulation
Time of dying was more than 2 days), excessive tissue amine can be produced in fish body, alimentary toxicosis can be caused.It addition, green grass or young crops accounts for fish
Fat content is high, is processed into dry products mouthfeel thick, and in preservation, easy oxidative rancidity, is also to limit its shelf life
Limit key factor, be suitable for for this efficient preservation method and natural antioxidant green grass or young crops is accounted for fish processing,
Storages etc. are particularly important.In research report at home and abroad, can pass through quick freezing, vitrification point is protected
The methods such as Tibetan, adds the Natural antioxidant such as vitamin C, vitamin E improve the texture quality of meat products.
Tea polyphenols and vitamin C, as a class Natural antioxidant, add in meat products, have removing free radical,
Prevent lipid peroxidation, be imbued with its good mouthfeel, improve product quality.The present invention will be by taking off
Fillet after fat are immersed in the compound anti-oxidation agent solution of certain density vitamin C and tea polyphenols, preferably
Ground keeps goods local flavor and quality, extends green grass or young crops and accounts for the freshness date of fish product.
Summary of the invention
The technical problem to be solved accounts for for green grass or young crops that fish product is fresh-keeping and oxidation control prior art
Not enough, it is provided that a kind of compound anti-oxidation technology keeps the method that green grass or young crops accounts for fillet product property, protects to greatest extent
Hold the quality of sample.This technical operation is simple, and practicality is stronger.
The technical solution adopted in the present invention is: a kind of compound anti-oxidation technology keeps green grass or young crops to account for fillet product property
Method, comprise the following steps:
1, Feedstock treating: select fresh green grass or young crops to account for fish, remove fish head, fish tail, fin and internal organs;
2, deburring: the green grass or young crops handled well is accounted for fish, picks a bone and cut open, removes the ventral spine of fish, Bian Ci and dirt, so
Clean up with circulating water afterwards, after draining, blue or green must account for fillet;
3, peeling: fillet are placed in 85-90 DEG C of hot water immersion 10 seconds, cold after scrape off fish epidermis and subcutaneous fat
Fat;
4, defat: the fillet after peeling are placed in mass fraction is 0.5%NaHCO3With 1%NaCl solution
In carry out defat 1h, fish and water is than 1:3g/ml, and ungrease treatment temperature 10 DEG C, period is stirred once every 20min;
5, anti-oxidant treatment: the fillet after defat are placed in composite natral fresh-keeping liquid immersion 15-30min, so
After dry under the conditions of 25-35 DEG C, natural Multiple preservative solutions is made up of vitamin C, tea polyphenols and water, wherein
Vitamin C and tea polyphenols account for the percentage by weight of antistaling agent and are respectively as follows: 0.05%-0.2% and 0.05%-0.2%,
Remaining is water.;
6, dry: about 55 DEG C hot air dryings 3.5-4.0 hour, goods moisture controls at 18%-22%;
7, vacuum packaging: after the sample vacuum seal packaging vanning after drying, be stored in the freezer of-30 DEG C
Storage.
The invention has the beneficial effects as follows:
The present invention provides a compound anti-oxidation technology to keep the method that green grass or young crops accounts for fillet product property.By by defat
After green grass or young crops account for fillet and be immersed in the compound anti-oxidation agent solution of certain density vitamin C and tea polyphenols.Should
Method is simple to operate, and safety is high, can effectively keep its quality, significantly prolong storage period, the shelf-life 170
More than it, have a good application prospect.
Detailed description of the invention
The present invention by the fillet after defat being immersed in certain density natural composite antioxidant solution,
Preferably keep goods local flavor and quality.
The method that compound anti-oxidation technology of the present invention keeps green grass or young crops to account for fillet product property comprises the following steps:
1, Feedstock treating: select fresh green grass or young crops to account for fish, remove fish head, fish tail, fin and internal organs;
2, deburring: green grass or young crops step 1 handled well accounts for fish, picks a bone and cuts open, removes the ventral spine of fish, Bian Ci and dirt
Thing, then cleans up with circulating water, blue or green must account for fillet after draining;
3, peeling: the fillet after step 2 deburring are placed in 85-90 DEG C of hot water immersion 10 seconds, natural cooling
After scrape off fish epidermis and subcutaneous fat;
4, defat: it is 0.5%NaHCO that the fillet after step 3 being removed the peel are placed in mass fraction3And 1%NaCl
Carrying out defat 1h in solution, fish and water is than 1:3g/ml, and ungrease treatment temperature 10 DEG C, period is stirred every 20min
Once;
5, anti-oxidant treatment: the fillet after step 4 defat are placed in composite natral fresh-keeping liquid immersion
15-30min, then dries under the conditions of 25-35 DEG C;Described natural Multiple preservative solutions is many by vitamin C, tea
Phenol and water composition, wherein vitamin C and tea polyphenols account for the percentage by weight of antistaling agent and are respectively as follows: 0.05%-0.2%
And 0.05%-0.2%, remaining is water;
6, dry: by the fillet after step 5 anti-oxidant treatment in 50-60 DEG C of hot air drying 3.5-4.0 hour,
Goods moisture controls at 18%-22%;
