A cleaning and reusable biochemical degumming method for hemp fibers through immobilized pectinase lyase on calcium alginate microspheres

Abstract

The traditional extraction technique for hemp fibers is high energy consumption, serious pollution, excessive degumming and results in strength loss. Here in, a cleaning and reusable biochemical degumming method was...

Preparation of nanocellulose by a biological method from hemp stalk in contrast to the chemical method and its application on the electrospun composite film

“…2a and b. 30,31 Both CNFs and CNCs are typical cellulose I structure, and a low diffraction peak on the 110-crystal surface is due to the amorphous structure of acid-insoluble lignin, pectin, and protein, and the sharp narrow peak on the 200-crystal surface reveals the typical cellulose structure. 32,33 After fitting, the crystallinity index values of CNFs and CNCs reached 58.2 and 83.5%, respectively.…”

Sustainable solutions of using deep eutectic solvents for hemp degumming: A combined experimental and DFT study

“…Nevertheless, this approach is time-consuming, expensive, and exhibits variable degumming outcomes, making it susceptible to environmental influences. 9,10 Traditional chemical degumming primarily employs chemical reagents like acids, alkalis, or oxidants to remove gum components, resulting in effective degumming with broad applicability. Nonetheless, it comes with drawbacks, such as high energy consumption, prolonged treatment duration, and significant environmental pollution during the degumming process.…”
