d-Xylitol is a naturally occurring sugar alcohol present in diverse plants that is used as an alternative sweetener based on a sweetness similar to sucrose and several health benefits compared to conventional sugar. However, current industrial methods fo

The activity of a Mo-promoted Raney nickel catalyst was studied in the hydrogenation of xylose to xylitol. Kinetic measurements carried out in a laboratory scale pressurised slurry reactor (40–70 bar H2 and 80–130°C) with recycled catalysts revealed that the catalyst deactivates during the use...
Repeatability and recovery were obtained to evaluate precision of the LC-ELSD method and the results were showed in Table 5. The repeatability, in terms of the relative standard deviation (RSD) of the replicate measurements, was judged to be satisfactory (RSD < 5.06 %, n = 5). The recovery...
Batchwise, three-phase hydrogenation of xylose to xylitol over Raney nickel and anomeric equilibria of xylose were studied. Raney Ni catalyst was active but deactivated relatively rapidly. Kinetic measurements, carried out with recycled catalysts revealed that the catalyst deactivates during the use, ...
composition d of Example 5: 710 seconds composition e of Example 5: 340 seconds pure water: 48 seconds These measurements demonstrate that the liquid compositions according to the invention are more viscous and have more body than the prior art syrups. <...
Although xylitol crystallizes predominantly in the anhydrous crystal form in the process according to the present invention, also some amorphous xylitol may be present. The degree of crystallinity of the product is, however, generally high. According to DSC measurements the degree of crystallinity is ...
In vivo Measurements of Sulcal Plaque pH in Rats After Topical Applications of Xylitol, Sorbitol, Glucose, Sucrose, and Sucrose Plus 53 mM Sodium Fluoride In two series of experiments, Sprague-Dawley-derived rats were infected orally with cariogenic micro-organisms and fed caries-promoting diets. ...
After 24h of biofilm formation, the multiparametric measurements showed that xylitol in the presence of glucose caused predominantly genotypic differences but did not induce metabolic differences compared to the control. Thus, the availability of dietary carbohydrates in either a pure or combined form ...
Rheo-optical observations have allowed the determination of shear conditions to control the size of crystals by dispersion. A second part has been dedicated to the effect of shear on crystallization of xylitol by seeding by means of rheology. The measurements, although not reproducible, clearly show...
