Abstract

The invention discloses a production process for preparing starch syrup from rice. The production process comprises the following steps: (1) crushing and pulping; (2) liquefying; (3) carrying out column laminar flow heat preservation and solid-liquid separation; (4) extracting a rice protein nitrogen source; (5) saccharifying; (6) carrying out solid-waste-free filtering; (7) carrying out mixed bed refining and concentrating. According to the process disclosed by the invention, in a process of preparing the starch syrup, the energy consumption is reduced through blending high-concentration starch syrup, a pulping water temperature is controlled and the liquefying time is shortened; residual sugar is recycled from sugar-free grains produced in a production process and fat in the sugar-free grains is hydrolyzed by adopting alkaline lipase; protein of the rice sugar-free grains is hydrolyzed by proteinase to prepare an organic nitrogen source, and fermentation raw materials for foods and medicines. The process disclosed by the invention is remarkably better than a traditional process for preparing the starch syrup from the rice; the production cost is low and an additional value of a product is improved; the content of produced solid wastes is extremely less and the production process is economical and environmentally friendly.

Description

technical field [0001] The invention relates to a production process for preparing starch syrup from rice, which belongs to the field of deep processing of rice. Background technique [0002] Starch sugar is widely used in beverages, candies, cakes, beer and other foods. It is easy to use and is favored by the majority of food processing enterprises. Starch sugar has a long history in our country. It was recorded in "Qi Min Yao Shu" in more than 500 AD, and described in detail the method of making sugar from rice. The types of starch sugars can be roughly divided into glucose, maltose, fructose, maltodextrin, oligosaccharides, sugar alcohols, and complex sugars (alcohols) according to their composition. [0003] At present, most of the manufacturing process of starch sugar is saccharification first and then separation of sugar residue. During the saccharification process, impurities such as protein and fat react with themselves or combine with sugar to produce more by-produ...
