“…Operating conditions were: 0.05 mol/L H 2 SO 4 as mobile phase, flow rate of 0.8 mL/min, and temperature of column and detector set at 50 °C and 60 °C, respectively. For the total soluble sugar determination, the fruit juice was first subjected to acid hydrolysis, to convert probably present sucrose to its monomeric sugars (Sewwandi et al 2020 ). Thereafter, the total sugars were analyzed by DNS method.…”

By way of broadening the use of diverse sustainable bioethanol feedstocks, the potentials of Paper mulberry fruit juice (PMFJ), as a non-food, sugar-based substrate, were evaluated for fuel ethanol production. The suitability of PMFJ was proven, as maximum ethanol concentration (56.4 g/L) and yield (0.39 g/g) were achieved within half a day of the start of fermentation, corresponding to very high ethanol productivity of 4.7 g/L/hr. The established potentials were further optimally maximized through the response surface methodology (RSM). At the optimal temperature of 30 °C, yeast concentration of 0.55 g/L, and pH of 5, ethanol concentration, productivity, and yield obtained were 73.69 g/L, 4.61 g/L/hr, and 0.48 g/g, respectively. Under these ideal conditions, diverse metal salts were afterward screened for their effects on PMFJ fermentation. Based on a two-level fractional factorial design, nutrient addition had no positive impact on ethanol production. Thus, under the optimal process conditions, and without any external nutrient supplementation, bioethanol from PMFJ compared favorably with typical sugar-based energy crops, highlighting its resourcefulness as a high-value biomass resource for fuel ethanol production.

“…Dinitrosalicylic acid (DNS) method was employed for the total reducing sugar analysis (Miller 1959;Salari et al 2019). For the total soluble sugar determination, the fruit juice was rst subjected to acid hydrolysis, to convert probably present sucrose to its monomeric sugars (Sewwandi et al 2020). Thereafter, DNS method was used for the analysis of total sugars present.…”

By way of broadening the use of diverse sustainable bioethanol feedstocks, the potentials of Paper mulberry fruit juice (PMFJ), as a non-food, sugar-based substrate, was for the first time evaluated for fuel ethanol production. Without any external nutrient supplementation, the suitability of PMFJ was proven, as maximum ethanol concentration (56.4 g/L), and yield (0.39 g/g), were achieved within half a day of the start of fermentation, corresponding to a very high ethanol productivity of 4.7 g/L/hr. Using Response Surface Methodology, established potentials were further maximized through statistical optimization of process conditions of temperature (20 – 40 ⁰C), yeast concentration (0.5 – 2 g/L), and pH (4 – 6). At the optimal temperature of 30 ⁰C, inoculum size of 0.55 g/L, and pH of 5, ethanol concentration, productivity, and yield obtained were 73.69 g/L, 4.61 g/L/hr, and 0.48 g/g, respectively. Under this ideal process conditions, bioethanol from PMFJ compares favorably with typical sugar-based energy crops, highlighting its resourcefulness as a high value biomass resource for fuel ethanol production.

“…The value was 6.96± 0.03 g/100mL out of 16.33 g/100 mL total sugar [2,11,12,13] Overall, of all seven fruit juice samples with "no sugar added" claim, Sample G arose curiosity. This is because this sample has the lowest concentrations of the reducing sugars (dextrose and fructose).…”

The study examined the sugar types and sum sugars in selected brands of commercial fruit juice. The sugar types were determined base on the reducing properties of the monosaccharide sugars using Lane and Eynon method. Non-reducing sugar was estimated after it hydrolysis. The data obtained were subjected to statistical analysis using ANOVA and Hierarchical Clustering (Dendrogram). The results showed that there is no significant difference in the sugar content amongst the seven brands of fruit juice analyzed. However, the results indicated that there is significant difference in the sugar types (Dextrose, Fructose and Sucrose) found in the samples. Fructose was found to be the higher concentrated of the two reducing sugars determined (Dextrose and Fructose) across the samples analyzed. Sample B has the highest fructose and dextrose concentrations (5.22± 0.02 g/100 mL) and (4.92± 0.01 g/100 mL) respectively while G has the lowest concentrations of the two sugars (4.76± 0.01 g/100 mL) and (4.49± 0.01 g/100 mL). Maximum sucrose content was recorded in G (9.36± 0.02 g/100 mL) out of 18.61 g/100mL total sugar reported for the sample. Lowest sucrose was observed in sample E (6.96± 0.03 g/100mL) out of 16.33 g/100 mL total sugar. There is significant amount of sucrose in all the fruit juice sample analyzed
