Abstract

The invention discloses a wheat bran water-soluble dietary fiber drink and a preparation method thereof, and belongs to the technical field of food processing. The method includes the following steps: pretreatment; degreasing; enzymatic hydrolysis; batching; and inactivation. A by-product wheat bran after wheat processing is used as a raw material to prepare the water-soluble dietary fiber drink, the utilization rate of the wheat bran is greatly improved, and a new way is increased for resource utilization of the wheat bran; the prepared drink has high water soluble dietary fibers, and has the efficacies of increasing satiety, preventing constipation, reducing blood sugar, reducing blood lipid, resisting cancer and the like; and the method is simple in process, high in efficiency, low in cost, and suitable for large-scale industrialized production.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing a water-soluble dietary fiber drink using wheat bran as a raw material, and at the same time relates to a wheat bran water-soluble dietary fiber drink prepared by the method. Background technique [0002] With the rapid development of the world economy and industry, people's living standards have been greatly improved, and diets have become increasingly refined. Various civilized diseases caused by overnutrition and malnutrition, such as diabetes, cardiovascular and cerebrovascular diseases, obesity, intestinal cancer, and constipation seriously affect human health. Therefore, functional foods that can regulate human body functions, prevent diseases and promote health have attracted much attention. Dietary fiber, as the seventh largest nutrient, has prominent health functions, and has gradually become a focus of attention of nutritionis...
