Abstract

The invention belongs to the technical field of processing of dietary fibers, and discloses sisal hemp residue dietary fibers and a preparation method thereof. The preparation method comprises the following steps of taking sisal hemp residues after fiber extraction, cleaning the taken sisal hemp residues, removing impurities, performing drying, performing crushing, performing extraction with ethanol, and performing drying so as to obtain materials; dispersing the obtained materials in water, performing acidolysis under the condition of pH being 1.5-2.5, and performing centrifugal separation so as to obtain supernatant and precipitate; washing the precipitate with water, drying the washed precipitate, and crushing the dried precipitate so as to obtain sisal hemp residue insoluble dietary fibers; concentrating the supernatant, then adding anhydrous ethanol, performing precipitation, and performing centrifugal separation so as to obtain supernatant and precipitate; and washing the precipitate with ethanol, and drying the washed precipitate so as to obtain sisal hemp residue soluble dietary fibers. According to the sisal hemp residue dietary fibers and the preparation method thereof disclosed by the invention, the steps of performing pretreatment with the ethanol, and performing acidolysis and separation on the sisal hemp residue soluble dietary fibers and the insoluble dietary fibers are adopted, so that environmental pollution and resource waste caused by sisal hemp residues are avoided, the comprehensive utilization of sisal hemp resources is also realized, and the economic development of the sisal hemp industry is promoted.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber processing, and in particular relates to a sisal residue dietary fiber and a preparation method thereof. Background technique [0002] Sisal is a species of the genus Agave in the family Agaveaceae. It is a perennial herb and is the most widely used hard fiber in the world. Sisal fiber has long fiber, white color, tough texture, elasticity, and tensile strength Strong, wear-resistant, acid and alkali resistant, corrosion-resistant, not easy to slip and other characteristics, widely used in fishing, aviation, mining, transportation and other fields. Sisal is a very distinctive tropical economic crop. The area and output of sisal in China rank fifth and second in the world respectively, while the output per unit area is more than four times the world average, ranking first in the world. The planting of sisal is mainly distributed in subtropical regions such as Guangdong, Guangxi, Hainan, and ...
