An integrated process using acetic acid hydrolysis and deep eutectic solvent pretreatment for xylooligosaccharides and monosaccharides production from wheat bran

Valorization of Avocado Seed Wastes for Antioxidant Phenolics and Carbohydrates Recovery Using Deep Eutectic Solvents (DES)

“…These data, compared positively to enzymatic digestibility of phenolic-free AS solid (data not included in the current study), showing an improvement of more than 50%, thus concluding that pretreatment with DES is an appropriate method since it allows the increase in the digestibility of the raw material in addition to obtaining a separated stream rich in lignin. Additionally, it is known that DES can efficiently remove lignin and hemicelluloses from lignocelluloses materials but keep the glucan structure intact [ 67 , 68 ]. Betwixt the main advantages of using DES is that they are affordable, recyclable, biodegradable, biocompatible, and produce fewer toxic by-products [ 69 , 70 ].…”

Bioprocess development for the production of xylooligosaccharide prebiotics from agro-industrial lignocellulosic waste

“…Acid autohydrolysis assisted DES pretreatment of LCB for XOS production is also considered as a suitable green method due to less consumption of chemical residues. Ying et al [ 101 ] recently used acetic acid hydrolyzed wheat bran as raw material for further treatment with DES (ChCl/lactic acid) that proved to be effective in providing a total XOS yield of 62.9%, high arabinose (76.1%), glucose (83.8%) and xylose yields (54.8%) respectively. In the current biorefinery process, the integrated pretreatment systems involving DESs could boost the possibility of valorization of LCB, maximize the xylan extraction and hence, XOS production.…”
