Corn bran is a byproduct of the wet processing corn starch, used for feed industry or natural waste and low-value-added, not only caused by the extreme waste of resources, but also caused serious environmental pollution. Corn consumption in China in 2008 to 144.6 million tons, consumption of 96 million tons of feed, industrial consumption of 37.5 million tons, accounting for the the corn total amount was 25.93%, seen each year will produce large amounts of corn bran. The main component of corn bran dietary fiber, dietary fiber weight loss, prevent constipation, lowering blood pressure, reduce cholesterol and prevent colon cancer, and other important physiological functions. This study will provide cleaning industrial production of starch byproduct of corn bran, skim off the hybrid, high temperature extrusion modified, fine grinding and other processing, screening out the different particle size of corn bran dietary fiber powder, physiological features, powder properties, research, and finally through the response surface analysis to study the preparation of corn bran dietary fiber tablets. Dietary fiber on the market in the form of a powder application, when used alone as a nutritional fortifier, causing much inconvenience to the packaging, storage, transportation and consumption of the study, its main raw material to investigate the suppression of corn bran dietary fiber tablets the best technology, to provide new ideas of dietary fiber in the field of health food. The study will not only lay the theoretical foundation for its research in related fields, and also for its pioneering in the field of production and application of broad market prospects, and promote the further development of the corn deep processing industry. The main outcome of this study are as follows: the physiological functions of dietary fiber and its physical and chemical properties related to the test of its expansion force, water holding capacity, liposuction force cholesterol adsorption capacity and adsorption capacity of nitrite, cation exchange capacity were measured. The measurement results are as follows: Particle Size 0.096mm when the physical and chemical nature of the overall level of the maximum water holding capacity of 4.97g / g;: expansion force 5.29ml / g; the liposuction force 1.792g / g; adsorption of cholesterol's ability to 50μg / g, at pH = 2, at pH = 7 as 394.961μg / g; NO2-adsorption capacity at pH = 2 15.29μg / g, at pH = 7 weak ability 0.942μg / g ; cation exchange capacity and this granularity. Powder properties is the basic theory of Pharmacy, powder properties of tablet formulations designed tablet preparation, quality control, packaging has important guiding significance. Therefore this experiment was studied their density, degree of compression, the flowability and hygroscopicity. The results show that: the powder particle size of 0.096mm, the bulk density of 0.3405g/ml, a tap density of 0.4555g/ml, compression degree of 25.25%, and the flow rate for 2.97g / s, the angle of repose of 43.38 °, powder particle size and the form of a more diversified, and the the hygroscopicity minimum. Single factor on an experimental basis, to the pressure, microcrystalline cellulose, sodium carboxymethyl starch, as the response factor, friability, disintegration time as a response value using the the Design-expert7.1.6 design software, according, Box-Benhnken Centre combination of theory, using the best of the three factors and three levels of design corn bran dietary fiber tablets tablet conditions. Response surface analysis to determine optimum conditions for corn bran dietary fiber sheet: corn bran dietary fiber powder 67.4%, microcrystalline cellulose content of 15.9%, 16.2% sodium carboxymethyl starch content, magnesium stearate The content is 0.5% when the film diameter is 20mm, the pressure of 20KPa minimum friability of 0.739% Min disintegration time 80.5s, and the tablet surface is smooth and without missing, there is a slight salty taste is not easy to be fragments, lobes. The critical relative humidity of the mixed material measured showed that the optimal production of the product humidity of 78.51%.
