Automated sugar analysis

Abstract

Sugarcane monosaccharides are reducing sugars, and classical analytical methodologies (Lane-Eynon, Benedict, complexometric-EDTA, Luff-Schoorl, Musson-Walker, Somogyi-Nelson) are based on reducing copper ions in alkaline solutions. In Brazil, certain factories use Lane-Eynon, others use the equipment referred to as "REDUTEC", and additional factories analyze reducing sugars based on a mathematic model. The objective of this paper is to understand the relationship between variations in millivolts, mass and tenors of reducing sugars during the analysis process. Another objective is to generate an automatic model for this process. The work herein uses the equipment referred to as "REDUTEC", a digital balance, a peristaltic pump, a digital camcorder, math programs and graphics programs. We conclude that the millivolts, mass and tenors of reducing sugars exhibit a good mathematical correlation, and the mathematical model generated was benchmarked to low-concentration reducing sugars (<0.3%). Using the model created herein, reducing sugars analyses can be automated using the new equipment.Keywords: mathematical modeling; monosaccharide; chemical determination. Practical Application:This work can be used to develop technological innovations in reducing sugars food analysis procedures using mathematical modeling and computational sensor snapshots.

Hydrogels as promising platforms for engineered living bacteria-mediated therapeutic systems

“…The human body hosts complex microbial communities that play significant roles in physiology and disease [ 58 ]. Research has shown that the constant interaction between the intestinal microbiota and host is associated with certain types of inflammatory intestinal diseases, including ulcerative colitis and Crohn's disease [ 59 , 60 ]. Probiotic microorganisms (Lactobacillus species, Clostridium butyricum , Bifidobacterium, etc.)…”

Comparison of Titulometric and Spectrophotometric Approaches Towards the Determination of Total Soluble And Insoluble Carbohydrates in Foodstuff

“…In the Luff-Schoorl method, Cu 2+ ions which had not been reduced are determined iodometrically, while the reduced copper is determined in Lane-Eynon (Sá et al, 2018). Furthermore, total sugars are thence determined by converting nonreducing sugars into reducing sugars through acid or enzymatic hydrolysis (Marques et al, 2016;Tavares et al, 2010).…”
