Determination of sugars in depilatory formulations: a green analytical method employing infrared detection and partial least squares regression.
2011
A green analytical method was developed for the analysis of sugar-based depilatories. Three independent partial least squares (PLS) regression models were built for the direct determination of glucose, fructose and maltose without any sample pretreatment based on their attenuated total reflectance - Fourier transform infrared (ATR-FTIR) spectra. The models showed adequate prediction capabilities with root-mean-square-errors of prediction ranging from 7.04 to 12.55 mg sugar g(-1) sample. As a reference procedure, gradient liquid chromatography with on-line infrared detection, employing background correction based on cubic smoothing splines, was used. The analysis revealed changes in the suga…
Two Methods for Highlighting the Influence of Sugars Type on Fermentation Processes Produced by Staphylococcus Carnosus and Lactobacillus Curvatus
2011
Purpose of this paper is to establish the influence of different types of sugars on fermentation processes found in the meat industry. In the analysis used a mixture of bacteria (Lactobacillus curvatus and Staphylococcus carnosus ), and the types of sugars were used lactose, lactulose, sucrose and two types of glucose syrup. To highlight the speed with which the fermentation process takes place, the variation in pH for the environment and the amount of energy released during biotechnological processes was measured.
Changes in properties of palm sugar syrup produced by an open pan and a vacuum evaporator during storage
2013
International audience; The aim of this study was to monitor the changes in the properties of palm sugar syrup produced by an open pan and a vacuum evaporator at 70°C and 80°C during storage under 4°C and room temperature (30°C) for 12 months at monthly intervals. During storage, Maillard reaction took place in samples stored under 4°C lower than those stored under 30°C. This was shown by lower a* values, intermediate browning products (IBP), browning intensity (BI) and HMF content, and higher L* values, fructose, glucose and free amino group contents during storage for 12 months. HMF, a possible mutagen formed by nonenzymatic browning during the heating and storage of sugar based products,…
