An optimization process with a cheap and abundant substrate is considered one of the factors affecting the price of the production of economical 2,3-Butanediol (2,3-BD). A combination of the conventional method and response surface methodology (RSM) was applied in this study. The optimized levels of pH, aeration rate, agitation speed, and substrate concentration (maltodextrin) were investigated...

Stevia is a natural, non-nutritive sweetener can replace sugar in your diet to control diabetes and aid in weight loss. Naanberenji, an Iranian traditional cookie, is a well-reputed confectionary containing high sucrose and calorie value, for this reason its consumption in healthy diet has been restricted. In this study, the effect of sucrose replacement by stevioside-maltodextrin mixture on ph...

Adding DE 18 maltodextrin (80 g kg(-1)) to high-fat minced mackerel was highly effective against lipid oxidation and protein and color changes during frozen storage. It increased the temperature of ice-melting onset (Tm') and decreased freeze concentration of solutes in the unfrozen water (UFW) phase, which would have allowed it to effectively slow such perturbations. This maltodextrin showed a...

Enterococcus faecium is a gut commensal of humans and animals. In the intestinal tract, E. faecium will have access to a wide variety of carbohydrates, including maltodextrins and maltose, which are the sugars that result from the enzymatic digestion of starch by host-derived and microbial amylases. In this study, we identified the genetic determinants for maltodextrin utilization of E. faecium...

Experiments were conducted to develop low-fat soft dough biscuits using carbohydrate-based fat replacers (maltodextrin and guar gum). A central composite rotatable design was used to optimise the level of sugar 24-36%, composite fat (fat 10.5-24.5%, maltodextrin 10.4-24%, and guar gum 0.1-0.5%), ammonium bicarbonate 0.5-2.5%, and water 20-24% for production of low-fat biscuits. Diameter (P < 0....

AIMS Breastfeeding significantly benefits mothers and infants. We aimed to identify the determinants of its successful initiation. METHODS A retrospective study of 1893 mothers delivering healthy term singletons at a Swiss university hospital from 1/2008 to 3/2009 determined the associations between multiple breastfeeding and early postpartum parameters by univariate and multiple regression a...

Electrochemical scaffolds (e-scaffolds) continuously generate low concentrations of H2O2 suitable for damaging wound biofilms without damaging host tissue. Nevertheless, retarded diffusion combined with H2O2 degradation can limit the efficacy of this potentially important clinical tool. H2O2 diffusion into biofilms and bacterial cells can be increased by damaging the biofilm structure or by act...

Abstract Hazelnut oil (HO) is important in terms of fatty acid composition and bioactive substances. Although there are a few studies on hazelnut encapsulation, limited research the investigation different wall material combinations for microencapsulation oxidative stability microcapsules. This study aimed to evaluate effects (gum Arabic, sodium caseinate, whey protein, gelatine, modified starc...

In animals, glycogen phosphorylase (GP) exists in an inactive (T state) and an active (R state) equilibrium that can be altered by allosteric effectors or covalent modification. In Escherichia coli, the activity of maltodextrin phosphorylase (MalP) is controlled by induction at the level of gene expression, and the enzyme exhibits no regulatory properties. We report the crystal structure of E. ...

Strains of Escherichia coli lacking MalQ (maltodextrin glucanotransferase or amylomaltase) are endogenously induced for the maltose regulon by maltotriose that is derived from the degradation of glycogen (glycogen-dependent endogenous induction). A high level of induction was dependent on the presence of MalP, maltodextrin phosphorylase, while expression was counteracted by MalZ, maltodextrin g...
