The Research Of Wild Grape Seed Oil Microcapsule Production Process

Wild Grape seed oil is a strong function of oil, which are rich in unsaturated fatty acids, the original pigment anthocyanin, resveratrol and other biologically active ingredients, each has been demonstrated by many researchers, and to explore more mature Supercritical Fluid Extraction of oil production technology, and in Europe, America, Japan and other countries and regions has been developed into a variety of health food products for different groups of people. However, because the liquid oil in the storage, processing, transportation and so the process can easily be oxidized leading to rancidity and other negative phenomena, therefore, in order to extend product shelf life, so that it can better measurement and applications, subject to the mountain of grape seeds, the Arab Gum, maltodextrin, sucrose fatty acid ester, distilled monoglyceride, protein NC, carbohydrates, MA, monoglyceride, sucrose sters, Tween -80, Tween -60, -80 Span as test material, the use of orthogonal Test method, the mountain grape seed oil microcapsule production process were studied.HLB on emulsion stability of measured values and to determine the limitations of the single use of emulsifiers, emulsifier used in production, in the mountains, the production of grape seed oil microcapsules choose monoglyceride and sucrose ester emulsifier complex , after the compound emulsifier HLB value 14. Wall material by the ratio of wall-core ratio, the proportion of crosslinking agent determined to wall material ratio, the wall core ratio, the stabilizer composition, the proportion of cross-linking agent for 4 factors and 3 levels of analysis to microcapsules embedded rate of major Evaluation index, the optimum formula: wall material for the mixture of gum Arabic and maltodextrin, the ratio of 1:2.5, was 1% emulsifier, emulsion temperature is 60℃, stabilizer from 0.25% alginate Sodium and 0.05% xanthan gum combination; in the best temperature and homogeneous spray drying process parameters, based on the solution concentration, feed rate, feed temperature, the material temperature of just four factors analysis to product Microencapsulation efficiency indicators as assessed by orthogonal analysis, to determine the optimum process parameters for the solution concentration of 30%, feed rate of 35 mL/min, feed temperature is 60℃, the feed temperature is 80℃Conditions, the product rate of the microcapsules was 81.2%. By measuring, using the optimized formula and technology, mountain grape seed oil microcapsules water 2.6%, grape seed oil 56.7% Hanshan, microcapsule integrity of the structure, smooth surface, the surface of the wall material has good tightness and integrity. 91% of product solubility, high stability, and its size is 11.0 ~ 34.1μm, average particle size 23.6μm, a density of 0.8124, acid value 0.77, peroxide value of 6.6, compared to the physical and chemical related products, the results, the Production technology is reasonable. Of the mountain grape seed oil microcapsules moisture and storage stability and found that wild grape seed oil microencapsulation little moisture absorption, thus protecting the polyunsaturated fatty acids which can not be oxidized and decomposed to avoid nutrient loss.In the follow-up study, the coagulant can be used for products, wall material selection, retention and other functional components to further explore the content, you can also simulate gastrointestinal conditions, the release characteristics of products in order to promote the production of Mountain out of microencapsulated powder oil grape seed oil, used for a variety of functional foods development, so as to improve the health of residents and improve the "three high disease " the patient's physical, play a great role in promoting.
