In this study, physico-chemical properties of honeys samples obtained from different locations of Turkey were investigated. Moisture, diastase activity, Hydroxy Methyl Furfural (HMF), viscosity, acidity, total glucose+fructose, protein and ash contents of honey samples ranged from 17.1% to 20.0%, 10.9 to 17.9, 1.34 to 31.28 mg/kg, 2.48 to 8.42 Pa s, 18.2 to 47.5 meq/kg, 51.31% to 68.30%, 0.60% ...

Dilute sulfuric acid was used to pretreat coastal Bermuda grass at high temperature prior to enzymatic hydrolysis. After both pretreatment and enzymatic hydrolysis processes, the highest yield of total sugars (combined xylose and glucose) was 97% of the theoretical value. The prehydrolyzate liquor was analyzed for inhibitory compounds (furfural, hydroxymethylfurfural (HMF)) in order to assess p...

Bamboo is a potential lignocellulosic biomass for the production of bioethanol because of its high cellulose and hemicelluloses content. In this research, ethanol organosolv pretreatment with dilute sulfuric acid as the catalyst was studied in order to enhance enzymatic saccharification of moso bamboo. The addition of 2% (w/w bamboo) dilute sulfuric acid in 75% ethanol had a particularly strong...

The effects of time, acid concentration, temperature and solid concentration on dilute-acid hydrolysis of orange peels were investigated. A central composite rotatable experimental design (CCRD) was applied to study the individual effects of these hydrolysis factors and also their interdependence effects. The enzymatic hydrolysis of the peels by cellulase, β-glucosidase, and pectinase enzymes r...

Bio-based media, derived from cellulosic biomass depolymerisation or bioconversion processes, are composed of several chemicals and biochemicals. In this study, the main components of a hemicellulosic-based medium were analyzed using a dual detection HPLC method to separate and determine concentrations of the major monosaccharides (glucose, xylose, and arabinose), alcoholic and acidic component...

The chemical composition of rice hulls produced in an artisan mill and its conversion to fermentable sugars was investigated. The carbohydrate fraction represented 59.2% (w/w) of the dry hulls. Cellulose, with 36.6%, was the main component, followed by xylan with 13.9%. An important contribution of starch (8.7%) was also detected. The content of ash (19.6%) and lignin (15.5%) was comparable wit...
