The specific embodiment
Following embodiment will do further elaboration to the present invention.
Rice starch, wax property cornstarch, wheaten starch, cornstarch are commercial product, can gather grain face industry Co., Ltd, Sigma from national starch company, Shandong Xingmao Corn Development Co., Ltd., Zhucheng, Shaanxi Yang Ling, and companies such as Fluka buy.Grain Production of Amaranthus is a commercial product, can buy from Hejing County, Xinjiang Long March livestock technology Co., Ltd, green standing grain edible wild herbs seed marketing center, Jinan, agricultural science and technology Co., Ltd of Shandong Rising and other places.
Grain Production of Amaranthus starch is by the preparation of following method: Grain Production of Amaranthus at room temperature with 0.3% sodium hydroxide solution immersion 24 hours, is ground then, use the food processor homogenization processing; Outstanding slurry uses 60,100,270 successively; 400 eye mesh screens filter, filtrating with 7000 rev/mins centrifugal 10 minutes, behind abandoning supernatant and the xanthoprotein matter layer; Stratum granulosum is dispersed in again processes outstanding slurry in the water, centrifugal.2 times so repeatedly.Final centrifugation wet starch is 40 ℃ of oven dry down.
The pattern of starch granules and particle size determination: with the form and the size of the S-4800 of Hitachi type environmental scanning microscopic sample, operating voltage is 1.0kV.
Fig. 1 is the stereoscan photograph of ative starch particle.Can see that different ative starch has different forms and size.The size of Grain Production of Amaranthus starch is minimum, and the average-size of wheaten starch is maximum.The average-size of these ative starch particles is at 1-20 μ m.
The surface tension of ative starch aqueous dispersions is measured by du No ü y ring method.Table 1 is the relation of ative starch aqueous dispersions surface tension and concentration, can find out.Except that wheaten starch, with the increase of starch concentration, the surface tension of aqueous dispersion of starch obviously descends, and these these starch of explanation have certain surface-active, can be adsorbed on the liquid-liquid interface.Compare with protein with little molecular surface active agent, it is relatively poor that the particle emulsifying agent reduces capillary ability, but the particle emulsifying agent still can be stablized and is adsorbed on the interface.
A certain amount of ative starch particle is dispersed in the water, and being mixed with concentration is 15wt% starch granules dispersion liquid, is the 1:1 compounding emulsion by atoleine and water volume ratio, utilizes homogenizer that emulsion is carried out homogeneous 2 minutes (10000 rev/mins).The emulsion photo is taken by the OLYMPUS digital camera, and the emulsion microphoto is taken by VHX-1000 (Japanese Keyence Int. Trading company).
Fig. 2 is the O/W emulsion photo (placing 2 months) with the ative starch granulate preparation, can see except that potato starch, and be that emulsifying agent can form O/W type emulsion with the ative starch particle.Because starch granules has stronger hydrophily, therefore be prone to form O/W type emulsion.It can also be seen that from Fig. 2 the stable emulsion of particle emulsifying agent is easy to layering, this is the characteristic of the stable emulsion of particle emulsifying agent.Because emulsion particle is too big, because the effect of gravity makes emulsion layer and continuous phase be separated.But can see that the stable emulsion of ative starch is stable to the emulsion coalescence, can stablize some months.In deposition at the bottom of the bottle is the ative starch particle that is not adsorbed onto on the emulsion particle.
Fig. 3 is the microphoto with the O/W emulsion of rice ative starch granulate preparation; Can see that emulsion particle is circular, when the concentration of starch was 9wt%, the average-size of emulsion particle was about 350 μ m; Increase with starch concentration; The emulsion particle size reduces, and when starch concentration was increased to 30wt%, the emulsion particle average-size was reduced to about 50 μ m.It can also be seen that from Fig. 3 starch granules is adsorbed on the emulsion particle really.
Fig. 4 is the microphoto of the stable O/W emulsion of Grain Production of Amaranthus starch and wax property cornstarch, also can be clearly seen that, starch granules really be adsorbed on the emulsion particle surface.
The surface tension (mN/m) of table 1 ative starch particle aqueous dispersion is with the variation of concentration
