Specific embodiment
Succinic anhydride used in this experiment is purchased from Mike woods company, article No. 108-30-5, and product number is S817605；Glycerol is purchased from Mike woods company, article No. 56-81-5, product number G810575.
The acylation modification of 1 rapeseed protein of embodiment
The acylation modification of rapeseed protein includes the following steps:
(1) processing of rapeseed dregs.Rapeseed is shelled using hulling machine, removes amount of grease with oil press oil expression, takes dish Seed dregs of rice soxhlet extraction methods remove grease, air-dry and smash it through 80-100 mesh, obtain smashed rapeseed dregs.
(2) acquisition of rapeseed protein.According to the ratio that 10mL water is added in the smashed rapeseed dregs of every g, after being pulverized Ultrapure water is added in rapeseed dregs, with the NaOH solution tune pH to 11.0 of 1M, it is 11.0 that 1-2h, which is stirred at room temperature, while keeping pH, then High speed centrifugation (8000g, 20min) collects supernatant and is 4.5 with the hydrochloric acid tune pH of 1M, be centrifuged after standing 2h (8000g, 20min), liquid is discarded supernatant, washs precipitating 2 times with dehydrated alcohol, then with milli-Q water 1 time, freeze-drying obtains vegetable seed Albumen.The rapeseed protein extracted by the detection of BCA kit using the above method, it is found that the mass percentage of albumen is 85.34%.
(3) acylation modification of rapeseed protein.Take rapeseed protein obtained by step (2), be dissolved in deionized water (rapeseed protein with go The mass ratio of ionized water is 1:10), pH value of solution=9.0 are adjusted, dissolution is stirred at room temperature, rapeseed protein quality 5% is then added Succinic anhydride is reacted, and is acylated to rapeseed protein.In reaction process, the NaOH solution by the way that 1M is added dropwise is to guarantee pH 9.0.After succinic anhydride reacts completely, product is fitted into bag filter, puts and is dialysed in water to remove small-molecule substance, A water is changed every 1-2h, is dialysed after 6-8h, is taken the acylated protein solution in bag filter to be freeze-dried, obtain modified rapeseed protein.
Embodiment two prepares the acylated rapeseed protein film of edibility
Using the acylated rapeseed protein film of rapeseed protein preparation edibility modified in embodiment one.The specific method is as follows:
(1) the modification rapeseed protein solution of configuration 40g/L is taken water as a solvent.It is added and is modified in modified rapeseed protein solution The glycerol of rapeseed protein quality 20%, is placed in water-bath, uses magnetic stirring apparatus (revolving speed 500r/min) under the conditions of 60 DEG C 2h is sufficiently stirred, obtains into film liquid.By in the groove (10cm × 10cm × 1mm) for pouring into polytetrafluoro propylene mold at film liquid at Type, drying for 24 hours, takes off film in 27 DEG C, the constant-humidity constant-temperature drying box that relative humidity is 55-65%.The film is denoted as 5% acylated dish Seed protein film.
In addition, RPI film is prepared, the difference is that with 40g/L's according to the preparation method of 5% acylated rapeseed protein film Rapeseed protein solution replaces modified rapeseed protein solution.
(2) performance of each composite membrane is detected.
1) thickness (thickness) of five-spot calliper to measure film is used.Using stretched plastic film performance test Method (GB/T1040.3-2006) measures the tensile strength (tensile strength, TS) and elongation at break (E) of composite membrane.Laboratory Texture instrument (TA.XT2i Texture Analyzer, Stable Micro Systems, Godalming, UK), every time when test Control probe spacing is 5cm, test rate 1.5mm/s.Using national standard " plastic film and sheet material water vapor permeability test side The cup type method of method-" (GB 1037-1988) measurement composite membrane vapor transmission coefficient (WVP), moisture vapor transmission cup is replaced with beaker, it is dry Agent uses anhydrous cupric sulfate.Specific testing result is shown in Table 1.
The performance of each protein film of table 1
Thickness in table 1, tensile strength, the value of elongation at break and vapor transmission coefficient use average value ± standard deviation It indicates, n=5.Indicate that statistically there is conspicuousness (p < 0.05) with different alphabetic flags.
As seen from Table 1, compared with RPI film, 5% acylated rapeseed protein film has stronger mechanical performance and water-resisting ability.
2) the optical property detection of film, concrete outcome are shown in Table 2.Its coloration is measured using chromascope, reading with CIE1976 chrominance space value L* (it is dark → bright: 0 → 100), a* (green-→ red+), b* (blue-→ yellow+) indicate.Total color difference is with Δ E is indicated.Wherein Ls、asAnd bsFor the value of standard white plate, respectively 98.07,0.16 and 2.42.The calculation of Δ E such as formula (1) shown in:
The results are shown in Table 2.
2 optical property testing result of table
Protein film L a* b* ΔE
RPI film 64.27±1.49a 3.06±0.42a 55.55±1.75b 63.07±0.44b
5% acylated rapeseed protein film 72.18±1.42b 3.32±0.89a 40.11±2.12a 45.87±0.39a
L, a*, b* and Δ E value are indicated with average value ± standard deviation in table 2, n=3.It is indicated with different alphabetic flags Statistically there is conspicuousness (p < 0.05).
The color sense organ of packaging material affects the consumption acceptance level of packed article, therefore the modification tool of protein film color It plays a very important role.As shown in Table 2, contrast standard blank, the color total color difference Δ E of RPI film are 63.07 ± 0.44, and 5% The total color difference of acylated rapeseed protein film is reduced to 45.87 ± 0.39, and lightness l value increases 72.18 from 64.27 ± 1.49 ± 1.42, it follows that 5% succinic anhydride can effectively improve the color of rapeseed protein, and albumen lighter is promoted to bleach, Be conducive to rapeseed protein further to utilize.
3) the surface hydrophobic detection of film.The surface hydrophobic of film is by measuring water droplet on protein film, when stopping the several seconds Between after the static contact angle that measures judge the hydrophobicity of film.Pass through OCA-20 contact angle analyzer (DataPhysics Instruments, GmbH, Filderstadt, Germany) estimation film surface hydrophobic.Measurement result shows connecing for RPI film Feeler is 77.66 °, and the contact angle of 5% acylated rapeseed protein film is 108.68 °.It is found that the acylated hydrophobic work for facilitating protein film With conducive to the stability of protein film.
4) the apparent form detection of film.Using scanning electron microscope (TM3000Tabletop Microscope, HITACHI, Japan) observation protein film apparent form.Concrete outcome is shown in Fig. 1.As shown in Figure 1, the RPI film surface not being acylated It is coarse, there is granular sensation, and 5% acylated rapeseed protein film surface is finer and close, uniform and smooth, and without large grained foreign matter.It is above-mentioned The result shows that acylation can improve the structure of albumen, keep protein structure finer and close, smooth, improve its mechanical performance and blocks water Performance.
5) the secondary structure detection of film.Using the secondary structure variation of Fourier transform infrared detection protein film.Use two Order derivative combination gaussian curve approximation method handles data, as a result such as Fig. 2.From Figure 2 it can be seen that after acylated, the β-in albumen (β-sheet) is folded to dramatically increase, and alpha-helix (α-helix), β-corner (β-turn) and irregular curling (random Coil it) significantly reduces, secondary structure changes.Protein is after succinylation is modified, due to the introducing of succinyl group, Charge, structure change, so as to cause property change.
