Abstract:
An antimicrobial lignin composition derived from wood biomass for use as a food additive is described. The additive comprises enriched lignin, carbohydrates and water. A method of making a microbial inhibiting food matrix and a method of treating food to inhibit microbial growth are also described.
Abstract:
The present disclosure relates to a process for extracting sugars from a pretreated lignocellulosic biomass. This process consists of contacting the pretreated lignocellulosic biomass with low charges of an aqueous peroxy acid (PA) solution to produce a liquid fraction (containing a small amount of lignin and hemicellulose degradation products) and a solid fraction containing cellulose, hemicellulose and lignin. The solid fraction can then be subjected to enzymatic hydrolysis with a variety of cell wall-degrading enzymes to produce a lignin-rich residue and a sugar solution that can be fermented to a variety of (bio)chemicals.
Abstract:
The present relates to a process for incorporating of wet natural fiber and starch into thermoplastics and the composite produced. The process for producing the composite comprises steps of: providing a wet natural fiber; providing a starch; providing a plasticizer; providing a thermoplastic; mixing the wet natural fiber, the starch and the plasticizer with water to produce a paste, and compounding the paste with the thermoplastic to produce the composite. The composite in a preferred embodiment comprises 50 weight % natural fiber/starch and a plasticizer; 50 weight % thermoplastic; a tensile modulus greater than 1450 MPa and a tensile strength greater than 41 MPa.
