Description

Technical Field

[0001] This invention belongs to the technical field of dietary fiber compositions, specifically relating to a dietary fiber composition that adsorbs oils and its preparation method and application. Background Technology

[0002] Dietary fiber is a polysaccharide that cannot be digested and absorbed by the gastrointestinal tract, nor can it produce energy. Based on whether it is soluble in water, dietary fiber can be divided into two main categories: soluble dietary fiber and insoluble dietary fiber. Soluble dietary fiber, such as pectin, hemicellulose, and certain oligosaccharides, plays an important role in blood sugar control and cholesterol regulation. Insoluble dietary fiber, such as cellulose and lignin, plays an important role in promoting intestinal peristalsis and increasing stool volume.

[0003] Meanwhile, both soluble and insoluble dietary fiber have strong adsorption capabilities. During digestion, they can adsorb and encapsulate fats, thereby slowing down the absorption rate of fats. Therefore, dietary fiber has a significant effect on reducing the harm of a high-fat diet, and the main method for evaluating the effect of dietary fiber on the rate of fat absorption is the oil-holding capacity test; the higher the oil-holding capacity...

[0004] Patent CN113100445A discloses a method for preparing and applying white kidney bean nanocellulose with strong oil adsorption properties, belonging to the field of nutrition and health. This invention uses a mixture of white kidney bean residue and bean husks as raw materials. Anti-nutritional factors in the white kidney bean residue are passivated using a combination of radio frequency and ultra-high voltage physical fields. Then, white kidney bean nanocellulose is prepared by a combination of mechanical ball milling and directional enzymatic hydrolysis. Finally, the white kidney bean nanocellulose with strong oil adsorption properties is enriched through Pickering emulsion. The white kidney bean cellulose prepared by this invention has high biocompatibility and exhibits extremely strong adsorption of both oils and lipases. The oil-holding capacity of the prepared white kidney bean nanocellulose was measured, and the results showed that the oil-holding capacity of the prepared product can reach up to 25 g / g.

[0005] Since both soluble and insoluble dietary fiber have their advantages, mixing different dietary fibers to prepare dietary fiber compositions is one way to study how to obtain dietary fiber products with better performance.

[0006] For example, patent CN109288029A provides a betaine-type composition formulation with beet water-soluble dietary fiber as the main component for use as a food supplement, and its preparation method. In addition to beet water-soluble dietary fiber, the composition formulation also includes a film-coated betaine preparation, active polysaccharides, and intracellular antioxidants. The formulation of this invention has high stability and water solubility, and is not easily hygroscopic or deliquescent when exposed to air, which is beneficial for storage; it can be uniformly dispersed in water and maintain a stable suspension state during use. However, it does not conduct a comprehensive study on the oil-holding capacity of the product, only measuring its stability.

[0007] Due to the targeted nature of existing dietary fiber product development, the complexity of dietary fiber components, and the need for large-scale dietary fiber production processes, there is a lack of development and research on dietary fiber composition products in this field. Therefore, providing a dietary fiber composition that exhibits good oil-holding capacity is one of the important research issues in this field. Summary of the Invention
