Description
Technical field
The invention belongs to packaging material for food fields, relate generally to a kind of preparation method of active packing film.
Background technique
Traditional packaging material durability, machinery and barrier property are preferable, easy to process, at low cost, are widely used in
All trades and professions, but this packaging material usually requires the time of centuries to decompose.In recent years, using protein, polysaccharide and
The renewable resources such as lipid prepare packaging material and are widely studied for substituting traditional polymer packaging.But biodegradable plastic
Them are made to be difficult to use in food packaging there are drawbacks such as mechanical performance and poor waterproof properties.
Cracking rice is important by-products during Rice producing, but not high to the utility value cracked rice in industry at present.
Middle content of starch of cracking rice is about 75%, therefore, can carry out starch isolation to cracking rice to improve its industry value.Starch due to its at
This is lower and is capable of forming the tasteless colourless polymer matrix of hypoxemia permeability and be used to develop film, one of potential use
It is the biodegradable food packaging of production, makes positive contribution to reduce environmental pollution.
Summary of the invention
The technical problem to be solved by the present invention is to overcome above-mentioned the deficiencies in the prior art, a kind of active packing film is provided
Preparation method reaches the recycling that by-product is cracked rice, increases the purpose of its commercial value.
A kind of preparation method of active packing film, method includes the following steps: the extraction of (1) broken starch of rice；(2)
Fish protein extracts；(3) active packing film preparation.
Broken rice starch extraction process described in step (1) are as follows: broken rice passes through dipping by lye, sieving, centrifugation, alkali cleaning 2
Secondary, washing, centrifugation adjust pH, centrifugation, washing and drying to obtain rice starch, and the lye is mass concentration 0.1%
NaOH, lye additive amount are to crack rice 2 times of quality, and the specification of sieve is 63 μm, centrifugal condition 10000g, 5min, adjust pH and are
6.5。
Fish protein extraction process described in step (2) are as follows: the flesh of fish is mixed with deionized water according to quality for 1:9,
3 min of homogenization after mixing is added lye and dissolves out Fish protein, the soluble protein in middle layer is adjusted pH to 5.5 after centrifugation,
It is centrifuged and is precipitated, Fish protein obtained by drying will be precipitated, the centrifugal treating condition is 9000g, 20min.
Active packing film preparation technique described in step (3) are as follows: by rice starch, Fish protein and water according to mass ratio be 1:
(0.5-1): 3 carry out being mixed to get mixed liquor, homogenization after the pH of mixed liquor is adjusted to 11, and mass fraction is then added and is
20-25% glycerine, and 20min is stirred under 80 DEG C of water bath conditions, it is 4-8% wild marjoram essence that the dense cream of quality is added after being cooled to 35 DEG C
Solution after homogeneous is placed in the Petri dish that diameter is 9cm and forms a film by oil, homogenization 10min, the membrance casting condition
Are as follows: dry 12h in 40 DEG C of air circulating ovens cools the temperature to 25 DEG C and places for 24 hours.
Solid content is 3% in the step (3), and the ratio of crack rice starch and Fish protein is 1:1, Herba Origani Vulgaris quintessence oil concentration
It is 6%, glycerol concentration 25%, obtained film thickness is 0.075mm, solubility 8%, moisture-vapor transmission 0.18g
mm kPa-1h-1m-2, tensile strength 5.69MPa, elongation percentage 85.5%.
This method carries out compounding production active packing film by will crack rice starch, fish protein and Herba Origani Vulgaris quintessence oil, not only mentions
The utility value that high byproduct is cracked rice, while the native compounds such as plant extracts and herbal medicine essential oil are mixed can in packaging film
It is effectively prevent or reduced the effect of food spoilage caused by aoxidizing, provides theoretical basis for the development of biodegradable material.
