Abstract
The invention discloses an air regulation optimized fresh-keeping method for asparaguses, of which the technical process comprises the following steps of: (1) selecting superior healthy straight asparaguses of which grass height is 25 cm and diameter is 6-18 mm, and packaging the selected asparaguses in a bag; (2) mixing gas with a gas proportion mixer, wherein the mixed gas is composed of CO2, O2, Ar and N2; (3) vacuumizing the bag with an air regulating package machine, aerating the bag with the mixed gas, and performing heat sealing to execute air regulation package; and (4) refrigerating the packaged fresh asparaguses at temperature of 2.5-3.5 DEG C. In the air regulation package step, the aerated gas includes the CO2, the O2, the Ar and the N2, and the gas volume mixing ratio of the four gases is as follows: 0-20% of the CO2, 0-20% of the O2, 0-5% of the Ar and 65-100% of the N2; and the ratio of the numerical value of the amount of the volume of the aerated gas counted by millimeter to the numerical value of the weight of the asparaguses counted by gram is 3/1-2/1. Compared with the traditional asparagus fresh-keeping method, the method can effectively prolong the shelf life of the asparaguses, and in the shelf life, the appearance of the asparaguses is similar as that of the fresh asparaguses.
Description
Technical field
The invention belongs to food processing storage technique field, relate to a kind of Vegetable Preservation method, particularly relate to the air regulating fresh-keeping method of asparagus.
Background technology
Asparagus (Asparagus Officinal is L.cv Jersey Giant) claim asparagus, asparagus or wild lucid asparagus etc. again, belongs to the perennial plant that the Liliaceae asparagus belongs to.Respiration was vigorous after asparagus was gathered, the rapid bad change of quality, and green asparagus (is generally 0～5 ℃) at low temperatures, and fresh and tender state also can only be kept 3 days.
MAP (Modified Atmosphere Package) gas flush packaging method is about to the tender stem of asparagus and packs with plastic sheeting, pre-set gas componant is charged into, rely on asparagus self respiration and film that the permeability of gas is regulated a bag composition of gases within then, thereby reach fresh-keeping purpose.
Shen Lian waits the people to publish an article in " Zhejiang agricultural journal " " research of asparagus MA P controlled atmosphere (2000,16 (1): 42-46) " clearly, shows at 5 ℃ 5%O
2+ 5%CO
2And 10%O
2+ 10%CO
2The MAP holding conditions under, the asparagus after 18 days still has quality preferably.
The publishing an article of Chen Ming " the storage and freshness-retaining technology research of asparagus (2006,5:117-119) " at " food science and technology ", the result shows, at 3 ℃, 10%O
2And 7%CO
2MAP storage down, after 10 days, the organoleptic quality of asparagus remains unchanged substantially.
People such as M.J.Villanueva publish an article at " food chemistry " " Physical; chemical; histological and microbiological changes in fresh green asparagus (Asparagus officinalis; L.) stored in modified atmosphere packaging (2005; 91 (4): 609-619) ", the result shows: under 2 ℃, and MAP (21%O
2+ 0.3%CO
2) storage, the shelf life of asparagus is compared common refrigeration and has been prolonged 12 days.
Up to the present, the asparagus shelf life is maximum 3 days under the conventional refrigeration condition, and general controlled atmosphere is in conjunction with under the refrigerated condition, and the asparagus shelf life at most also just reaches 18 days.Therefore, study and a kind ofly can guarantee product quality, the optimization air regulating fresh-keeping method that can reach significant prolongation asparagus shelf life again is a problem that waits to solve.If can address this problem, just can sell new fresh asparagus the preservation technique guarantee is provided for the supermarket.
Summary of the invention
The object of the invention provides the controlled atmospheric packing preservation method of the optimization that a kind of suitable supermarket asparagus sells, and this technology can significant prolongation asparagus shelf life, and is easy and simple to handle, has stronger practicality.
The present invention program's technological process is as follows: (1) selects the top grade asparagus of the long 25cm of stem, diameter 16-18mm, not crooked, no disease and pest, the packaging bag of packing into; (2) mix gas with proportional gas mixer, the composition of mist is CO2, O2, four kinds of gases of Ar and N2; (3) vacuumize, inflate and seal mouth with gas-control packing device and carry out controlled atmospheric packing; (4) fresh asparagus with above-mentioned packing refrigerates, and refrigerated storage temperature is 2.5-3.5 ℃.
Controlled atmospheric packing charges into gas and has adopted CO
2, O
2, Ar and N
2Four kinds of gases, gas volume proportioning ratio is: CO
2Be 0-20%, O
2Be 0-20%, Ar is 0-5% and N
2Be 65-100%.The numerical value of the gas milliliter that charges in the packing with the ratio of the numerical value of asparagus quality is: 3: 1 to 2: 1.
Through preferred, the volume proportion ratio of above-mentioned four kinds of gases that charge into is as follows: CO
2Be 3-6%, O
2Be 11-15%, Ar is 2-5% and N
2Be 75-85%.The numerical value of the gas volume milliliter that charges in the packing with the ratio of the numerical value of asparagus quality is: 3: 1.
The present invention adopts suitable O
2Content suppresses the tender fasciated fiberization of Vc, chlorophyll degradation and asparagus to asparagus and plays important effect, low excessively oxygen environment, and asparagus will carry out violent anaerobic respiration; And in the oxygen environment, asparagus carries out aerobic respiration again, control O
2Content plays topmost effect to asparagus is fresh-keeping under a lower ratio.The present invention compares with traditional asparagus air regulating fresh-keeping method, has not only prolonged freshness date, and outward appearance and new fresh asparagus are comparatively approaching.
The specific embodiment
Optimize air regulating fresh-keeping method for fully disclosing asparagus of the present invention, be illustrated below in conjunction with embodiment.
Select the top grade asparagus of the long 25cm of stem, diameter 16-18mm, not crooked, no disease and pest, the packaging bag of packing into; Mix gas with proportional gas mixer, carry out controlled atmospheric packing through vacuumizing, inflate and seal mouth with gas-control packing device; Use Domestic MAP-H360 controlled atmosphere fresh-keeping packing machine to mix gas, vacuumize, inflate and seal a mouthful packing.
Adopt orthogonal test to investigate 3 ℃ of different down initial O
2/ CO
2/ Ar/N
2Gas ratio is to the influence of asparagus storage quality.The numerical value of the gas volume milliliter that charges in the packing with the ratio of the numerical value of asparagus quality is: 3: 1.Asparagus carries out the MAP packing and preserves and measure asparagus sense organ, weight-loss ratio, Vc, chlorophyll and 5 indexs of content of cellulose after 28 days, and experimental result utilization variance analysis and the new multipole difference of Duncan ' s multiple ratio draw initial O
2Content is the greatest factor that influences the asparagus storage quality, at O
2Be 12%, CO
2Be 8%, Ar is 3% and N
2Be that the storage quality of asparagus is best, after 28 days, can also keep good organoleptic quality in 77% the initial gas proportion, the asparagus after fresh-keeping has higher Vc and chlorophyll content, lower percentage of water loss and content of cellulose.
