Description
Technical field
The present invention relates to agricultural, biology and food technology field more particularly to a kind of starch film systems for inhibiting to adopt rear fungi
Preparation Method.
Background technology
Extend fruit shelf life, nutrient quality is protected to be a long-range mission of postharvest biology.For a long time, fruit
Packaging material is mainly based on plastic film, including bidirectional stretching polypropylene film（BOPP）, low-density polyethylene film
（LDPE）, nylon film（PA）Deng, but these film generally existing biodegradabilities are poor, easily cause " white pollution ".With life
The material of Biodegradable is prepared the hot spot that edible packing membrane replaces current plastic film to become current research by matrix.Wherein
Starch film is of concern since its is cheap, but starch film strength is weak and water vapo(u)r transmission is big, so it is applied
It is constantly subjected to limit.The shortcomings that in order to overcome it, improves its functional characteristic, and starch is usually passed through following several chemical modification sides
Formula achievees the purpose that improve performance.(1) esterification modification, in patent CN107141516A, with potato starch and its octenyl amber
Amber acid-starch ester is used in compounding, and using glycerine as plasticizer, while being added to Herba Origani Vulgaris quintessence oil, greatly strengthens the anti-of edible film
Bacterium performance.But the viscosity of starch increases after esterification modification, and difficulty is increased going the bubble removing stage.(2) etherification modified, such as specially
In sharp CN106496653A, low substitution degree hydroxy-propyl starch/sodium alginate compound is prepared.Obtained hydroxypropyl starch ether is not
On the basis of influencing its transparency and mobility, the mechanical property of starch film greatly improves.But as sodium alginate price compared with
Height is suitble to industrial applications.(3) oxidation modification, as utilized hydrogen peroxide by starch oxidation in patent CN105906853A, glycerine is
Plasticizer, pasty liquid prolong stream film forming on a glass, and fruit-vegetable plastic wrap is obtained after cooling drying.But oxidized starch is to temperature-sensitive
Sense, darkens when temperature is high, influences its transparency.In addition, at present there has been no for adopt rear fungi bacteriostatic starch film report,
Therefore it develops a kind of environmental protection, high mechanical strength, the method for adopting the bacteriostatic starch film of rear fungi can be inhibited to become particularly important.
Invention content
Technical problem to be solved by the invention is to provide a kind of easy to operate, good inhibition of properties of product to adopt rear fungi
Starch membrane preparation method.
To solve the above problems, a kind of starch membrane preparation method for inhibiting to adopt rear fungi of the present invention, including it is following
Step：
(1) the distilled water of 30 ~ 100 times of its quality is added in starch, it is gelatinized completely in 90 DEG C, obtains gelatinized starch；
(2) the acetic acid solution that the volumetric concentration of 50 ~ 100 times of its quality is 1 ~ 10% is added in chitosan, it is in 30 ~ 80 DEG C that its is molten
Solution, obtains clear solution；The dosage of the chitosan accounts for the 30 ~ 70% of the starch quality；
(3) it is uniformly mixed after the gelatinized starch being cooled to room temperature with the clear solution, obtains mixture, in the mixture
Glycerine and essential oil are added, bubble is removed through emulsifying, ultrasonic wave, obtains film liquid；The glycerine additive amount is the starch quality
10 ~ 40%；The additive amount of the essential oil is the 20 ~ 95% of the starch quality；
(4) the film liquid is cast on polytetrafluoroethylene, and drying obtains uniform film；
(5) the film, which is placed in growth cabinet, balances post package, preserves into 4 DEG C of refrigerators up to starch film.
The step (1) in starch refer to cornstarch, micropore cornstarch, octenyl succinate cornstarch is micro-
One kind in the octenyl succinate cornstarch of hole.
The step (3) in essential oil refer to anethole in Fructus Foeniculi quintessence oil or Fructus Foeniculi quintessence oil, fennel aldehyde monomer
Component.
The step (3) in emulsifying condition refer to homogenization pressure be 20 ~ 100MPa, the time be 30 ~ 60min.
The step (3) in ultrasonic wave go bubble condition refer to ultrasonic power be 120 ~ 600W, the time be 20 ~
40min。
The step (4) in drying condition refer to temperature be 30 ~ 100 DEG C, the time be 12 ~ 72h.
The step (5) in equilibrium condition refer to humidity set be 40 ~ 70%, equilibration time be 4 ~ 48h.
Compared with the prior art, the present invention has the following advantages：
1, since the present invention uses native cornstarch, micropore starch, octenyl succinate starch, micropore octenyl succinate
One or more of starch is used as starch matrix, wherein micropore octenyl succinate starch both to have good emulsibility
Can, and there is lower viscosity, filming performance is preferable（Referring to Fig. 1 ~ 2）, therefore so that starch matrix can be with derived essential oil shape
At good disperse system, simultaneously because starch its hydrolyze to form micropore during reduce starch viscosity, film forming bubble removing relatively holds
Easily, the film good mechanical property of formation（Referring to Fig. 3）.
The starch film properties test experiment of rear fungi is adopted to the inhibition of embodiment 1 ~ 6, the specific test method is as follows：
Measuring mechanical property：Using RG3010 material analyzers, when measurement tensile load be 100N, tensile speed 2mm/min,
The tensile strength of film, tensile strength are measured by ASTM (1995)（TS）It is indicated with MPa.
The measurement of penetrability：According to the method for (2000) ASTM, and slightly modified.Appropriate distilled water is added in moisture vapor transmission cup, so
Rim of a cup is tightly sealed with manufactured edible film afterwards, is put into after correct amount in the drier containing silica gel, then drier is put
To 25 DEG C of insulating boxs, weighed once every 4h, altogether for 24 hours.Film water vapor permeation coefficient (WVP, gmm/kPahm2) meter
Calculate formula：
Wherein：M-passes through the quality of film vapor, g；
The average thickness of d-film sample, mm；
Effective infiltrating area of A-sample, m2；
T-vapor passes through time, h；
△ P-moisture vapor transmission cup both sides water vapor pressure force difference.
The tensile strength and vapor transmission coefficient of 1 film of table
2, since the essential oil used in the present invention is the monomers such as anethole, anisaldehyde in Fructus Foeniculi quintessence oil or Fructus Foeniculi quintessence oil
It is notable to be applied to fruit post-harvest fresh-keeping fungistatic effect to cooperate with inhibition to adopt rear fungi growth with chitosan for component（Referring to Fig. 4）,
With good industrial application value.
3, easy to operate, the starch film of preparation of the invention（Referring to Fig. 5）Have the effect of that rear fungi is adopted in good inhibition, together
When solve the problems, such as that starch film bad mechanical strength and moisture-vapor transmission are high, be it is a kind of efficiently, environmental protection, be suitable for it is industrialized
Method.
