Isolation and Extraction of Monomers from Insoluble Dietary Fiber

Abstract

Insoluble dietary fiber is a macromolecular polysaccharide aggregate composed of pectin, glycoproteins, lignin, cellulose, and hemicellulose. All agricultural by-products contain significant levels of insoluble dietary fiber. With the recognition of the increasing scarcity of non-renewable energy sources, the conversion of single components of dietary fiber into renewable energy sources and their use has become an ongoing concern. The isolation and extraction of single fractions from insoluble dietary fiber is one of the most important recent research directions. The continuous development of technologies for the separation and extraction of single components is aimed at expanding the use of cellulose, hemicellulose, and lignin for food, industrial, cosmetic, biomedical, and other applications. Here, to expand the use of single components to meet the new needs of future development, separation and extraction methods for single components are summarized, in addition to the prospects of new raw materials in the future.

Genome-Wide Association Study Reveals the Genetic Basis of Crude Fiber Components in Brassica napus L. Shoots at Stem Elongation Stage

“…For example, color, texture, taste and smell are sensory qualities, while vitamins, proteins and minerals are features of the nutritional composition of the product. , One of the biggest influences on texture is the insoluble material present in the cell walls, because this largely determines the perception of smoothness and juiciness . The insoluble material forms the crude fiber (CF) content of the cell wall, which can neither be dissolved in water nor fermented by microorganisms in the large intestine and is formed of cellulose (Cel), hemicellulose (Hem) and lignin. , The contents of the different CF components can be expressed by determining the levels of neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL). , In addition, NDF and ADF are used as parameters to evaluate the feed available energy values and digestibility of ruminant feed . Researchers also use ADF and NDF as criteria to evaluate the digestibility of biofuel feedstock, and estimate the Cel and Hem concentrations of feedstock and bioethanol production .…”
