Problems solved by technology

Due to the low bulk density, poor heat transfer and fluidity of starch raw materials, it is not conducive to the scorching gelatinization reaction, resulting in uneven acid-heat reaction of starch, long reaction time, poor product quality and low yield in the existing resistant dextrin production method. low level problem
At the same time, in the production process of resistant dextrin in the prior art and preparation method, the by-products including glucose, maltose, maltotriose and other components have a high proportion, and the raw materials are not effectively utilized, which increases the production cost and reduces the product yield. Rate
In addition, the products produced by the prior art contain relatively high components such as glucose and oligosaccharides, which is not conducive to the application of the product in food for patients such as diabetes
Although there is a patent to further ferment or separate the glucose produced after enzymatic hydrolysis for sale, this method can improve the purity of resistant dextrin, but it will cause a lot of waste of glucose syrup and increase the production cost
In order to improve the uniformity of charcoal gelatinization reaction, there is a patent to add river sand in the reaction process, although it can improve thermal conductivity and uniformity of reaction, but it increases the volume of the reactor and the difficulty of operation, reducing the production efficiency

Abstract

The invention provides a processing method for improving the yield and the quality of resistant dextrin. The processing method comprises the following steps in sequence: performing acid treatment and spraying sugar liquid on starch serving as a raw material; granulating and drying the starch; coking and gelatinizing for the first time; spraying the sugar liquid for the second time; coking and gelatinizing for the second time; performing enzyme hydrolysis; performing chromatographic column decolorization and desalination; desugaring, refining and drying to obtain the resistant dextrin, wherein the sugar liquid obtained in the steps of desugaring and refining is concentrated to serve as the raw sugar liquid for spraying the sugar liquid for the first time and spraying the sugar liquid for the second time. According to the processing method, the sugar liquid separated in the steps of desugaring and refining is concentrated to serve as the raw sugar liquid and is mixed with the starch, so that the product yield is improved by 10 percent to 30 percent; the production cost is reduced; the uniformity degree of heat treatment is improved effectively, and the coking and gelatinizing effect and uniformity are improved by increasing a granulating process.

Description

technical field [0001] The invention belongs to the field of starch deep processing, in particular to a processing method for improving the output rate and quality of resistant dextrin. Background technique [0002] The research on resistant dextrin originated in Japan in the 1990s. It is a low-molecular water-soluble dietary fiber prepared from natural starch. It has low viscosity, low calorie, low sweetness, high solubility and good processing stability. In addition, it also plays an important role in regulating the physiological functions of the human body, such as lowering blood sugar, regulating blood lipids, and controlling body weight. Therefore, resistant dextrin has been widely used as food and food accessories in various foods such as beverages, jams, candies, dairy products, cereal foods, and functional foods. [0003] At present, the industrial and patented resistant dextrin production process uses various starches as raw materials, heats and reacts at high temp...
