The effect of sugar decomposed on the ethanol fermentation and decomposition reactions of sugars

Assessment of hydrolysis of cheese whey and use of hydrolysate for bioproduction of carotenoids by Sporidiobolus salmonicolor CBS 2636

“…Other authors have studied the sugar decomposition reactions during acid hydrolysis of sugar mixtures. Furfural, formic acid, acetic acid and 5‐hydroxymethylfurfural are reported to be products of sugar acid degradation at pH < 2, temperature > 100 °C and reaction time < 1 h 18…”

“…The bioproduction of carotenoids in the medium based on cheese whey hydrolysate prepared by enzymatic hydrolysis was approximately sixfold higher than that in the medium based on cheese whey hydrolysate prepared by acid hydrolysis. The reason for the low production using the acid hydrolysate may be related to the low glucose content and/or inhibitory by‐products produced during hydrolysis 18. In the acid hydrolysate the formation of coloured compounds was observed after hydrolysis, possibly due to the thermal degradation of saccharides and proteins catalysed by the acid.…”

Analysis of mono-sugars obtained by acid hydrolysis of algae-based polysaccharides

“…Acid hydrolysis process forms byproducts such as hydroxyl methyl furfural (HMF) and it is difficult to get yield over 65-70% [18,19]. Nevertheless, potential for development has been expressed about using acid hydrolysis process because of quick easy and inexpensive reaction process [20][21][22].…”

Kinetic study of recycled newspaper liquefaction in polyol solvent

“…EG can block the free-radical fragments and prevent the condensation of the fragments. Generally, hemicellulose is hydrolyzed in an aqueous solvent much faster than cellulose [8]. Considering these facts, the degradation rate of each component could be significantly different, which in turn would cause the liquefaction rate to change as the reaction proceeds.…”
