Abstract
The present invention discloses a method for keeping the freshness of belt fish by a way that a biological fresh-keeping agent is combined with a gas-adjusting package. The biological fresh-keeping agent is composed of chitosan, tea polyphenol, glacial acetic acid and water, wherein the weight percentages of the chitosan, the tea polyphenol and the glacial acetic acid occupied the biological fresh-keeping agent is respectively 0.5% to 1.5%, 0.2% to 0.6% and 0.5% to 1.5%, and the rest is the water. Gas filled in the gas-adjusting package is composed of CO2, O2 and N2, and the volume proportioning proportion is 50% to 80% CO2, 10% to 20% O2 and 10% to 30% N2.The method for keeping the freshness of belt fish has not side effect for human bodies, and the biological fresh-keeping agent has certain cancer-preventing cancer-resisting healthcare efficiency. The present invention has the advantages of simple operation, low cost, safety and environment protection, and can obviously prolong the shelf period of fresh belt fish.
Description
Technical field
The present invention relates to a kind of preservation method of aquatic products, relate in particular to the method that a kind of bio-preservative combines the fresh-keeping hairtail of controlled atmospheric packing.
Background technology
Hairtail (Trichiurus haumela) is the highest a kind of economic fish of the coastal output of China, and the annual production seventies generally about 500,000 tons, rises to more than 110 ten thousand tons the nineties, and its output occupies the first place of Chinese marine fishing fish output for many years always.Fertile, the delicious flavour of the tender body of hairtail meat has very high nutritive value.Because the domestic and international market improves constantly the requirement of fish freshness and fresh fish circulation quantitative change is big elongated with the circulation distance, seek a kind of safety and sanitation and preservation method that can significant prolongation hairtail shelf life and seem very important.
In China, have 70% to carry out freezing or cold storing and fresh-keeping in the fresh-keeping processing of aquatic products.Along with the raising of living standards of the people, frozen fish is freezed because of its local flavor and nutrition and thaws to be influenced greatlyyer, does not more and more receive consumer's welcome; Though and cold storing and fresh-keeping can be kept the fresh quality of hairtail preferably and can not satisfy its shelf life requirement; In seeking food fresh-keeping method, add some chemical preservatives in the food of being everlasting and carry out fresh-keepingly, but the use of chemical preservative is prone to people's health is worked the mischief, therefore seeking a kind of effective, safe preservation technique more and more receives people's concern.
Under the conventional refrigeration condition, the hairtail shelf life is about 5 days.About prolonging the research of hairtail shelf life under the freezing and refrigeration condition, forefathers did following work:
Tao Ningping etc. publish an article at " Shanghai Aquatic Products Univ. 9CN)'s journal " " hairtail controlled atmospheric packing technical study ", and (1997,6 (1): 59-62.), its research shows, under the 0-4 ℃ of refrigerated condition, through 60%CO
2+ 10%O
2+ 30%N
2The preservation of controlled atmospheric packing hairtail still was in the secondary freshness in 14 days.
" the lysozyme composite preservative is to the preservation of aquatic products " (2001 of publishing an article at " aquatic product journal " such as Chen Shunsheng; 225 (3): 254-259.); Its research shows; Hairtail refrigerates under 5 ℃ of conditions behind 0.05% lysozyme, 2.0% sodium chloride, 8% glycine, 0.08% potassium sorbate, 0.3% ascorbic acid composite preservative dipping 30s, plays certain fresh-keeping effect.
Outside last report, do not see the preservation technique that is fit to prolong the hairtail refrigerated shelf phase.Therefore, study and a kind ofly can guarantee product quality, preservation technique that again can the significant prolongation hairtail refrigerated shelf phase is a problem that waits to solve.
Summary of the invention
The preservation method that a kind of suitable supermarket hairtail that the present invention seeks under refrigerated condition, to provide is sold; Hairtail under refrigerated condition after bio-preservative is filmed carries out controlled atmospheric packing again; This technology can significant prolongation hairtail shelf life to 20 day more than, easy and simple to handle, have stronger practicality.
The present invention adopts following technical scheme:
Technological process of the present invention is following: 1. fresh hairtail truncates through decaptitating after internal organ handle, and cleans up with frozen water, is cut into the long section of 6-7cm, and drain the back and film with bio-preservative, and the packaging bag of packing into; 2. mix gas with proportional gas mixer, carry out controlled atmospheric packing through vacuumizing, inflate and seal three steps with gas-control packing device; 3. the bright hairtail with above-mentioned packing refrigerates, and refrigerated storage temperature is 4 ℃ ± 1 ℃.
Above-mentioned bio-preservative is made up of shitosan, Tea Polyphenols, glacial acetic acid and water, and wherein shitosan, Tea Polyphenols and the glacial acetic acid percentage by weight that accounts for antistaling agent is respectively: 0.5%-1.5%, 0.2%-0.6% and 0.5%-1.5%, all the other are water.The gas that controlled atmospheric packing charges into is by CO
2, O
2And N
2Three kinds of gas compositions, gas volume proportioning ratio is 50%-80%CO
2, 10%-20%O
2And 10%-30%N
2
Preferably, the percentage by weight that shitosan, Tea Polyphenols and glacial acetic acid account for antistaling agent in the above-mentioned biological preservation is respectively: 1.0%, 0.4% and 1.0%, and all the other are water.The volume proportion ratio that controlled atmospheric packing charges into gas is: 50%CO
2, 20%O
2And 30%N
2
Shitosan has effects such as antibacterial, antitumor in the bio-preservative that the present invention adopts.Tea Polyphenols is a polyphenols in the tealeaves, has anti-oxidant and bacteriostasis; Controlled atmosphere of the present invention is with the CO in the mist
2The growth and breeding that can suppress bacterium delays the quick growth of total number of bacteria.O
2The growth and breeding that can suppress anaerobe.Hairtail after bio-preservative is filmed through behind the controlled atmospheric packing under 4 ℃ ± 1 ℃ refrigerated condition shelf life can reach 24 days.
The specific embodiment
For fully disclosing the air regulating fresh-keeping method of hairtail of the present invention, explain below in conjunction with embodiment.
Embodiment:
1, bright hairtail is cut head and tail, cut off the abdominal cavity and remove internal organ, in frozen water, clean up, be cut into the long section of 6-7cm, drain,, dry pack with the biological preservation liquid that the prepares hairtail section of filming.
2, pack in the packaging bag through the film hairtail section that drains of bio-preservative above-mentioned, each hairtail section is adorned one bag.With reference to above process conditions, the PBI Densensor-MAP mix9000 air mixing machine that produces with Denmark mixes gas, and the DQB-360W type gas-control packing device of using marine products vacuumizes, inflation and heat seal, and gas volume proportioning ratio is 50%CO
2, 20%O
2And 30%N
2
In the above-mentioned controlled atmospheric packing process, the parameter that is provided with of gas-control packing device and gas mixer is: vacuumize 5s-15s, and inflation 1s-5s, 120 ℃-150 ℃ are sealed; Gas mixed-precision＜2%, power gas source are 7-8kg/cm
2, mixing fresh-keeping gas pressure is 4.0-5.0kg/cm
2, fresh-keeping source gas pressure 5kg/cm
2
In the above-mentioned controlled atmospheric packing process, the numeric ratio of the numerical value of the gas volume that charges in the packing (ml) and hairtail weight (g) is 3: 1, and promptly per 1 gram hairtail charges into the mist of 3ml.
3, the hairtail section of above-mentioned packing is positioned in 4 ℃ ± 1 ℃ cold storage environment preserves.Hairtail section freshness date can reach 24 days.
Compare with traditional hairtail preservation method, significant prolongation of the present invention the shelf life of hairtail.
