A study was done on the feasibility of inulin, a fructooligosaccharides with the health benefits of prebiotic, as partial sugar replacer in “kaya” by investigating the effects of different substitution levels (0%; control, 10%, 30% and 50%) on the sensory properties. The samples were investigated by 10 descriptive panelists for colour, sweetness, smoothness, firmness, adhesiveness and spreadabi...

3. SACN have reviewed the available scientific evidence for components under consideration for inclusion in the Codex definition on dietary fibre for nutrition labelling purposes, using the SACN frame work for assessing evidence (SACN 2002). These components include total fibre, non starch polysaccharides, fibre components from cereal, fibre components from fruit and vegetables, starch, resista...

BACKGROUND Filamentous fungi are versatile cell factories and widely used for the production of antibiotics, organic acids, enzymes and other industrially relevant compounds at large scale. As a fact, industrial production processes employing filamentous fungi are commonly based on complex raw materials. However, considerable lot-to-lot variability of complex media ingredients not only demands ...

BACKGROUND IslA4 is a truncated single domain protein derived from the inulosucrase IslA, which is a multidomain fructosyltransferase produced by Leuconostoc citreum. IslA4 can synthesize high molecular weight inulin from sucrose, with a residual sucrose hydrolytic activity. IslA4 has been reported to retain the product specificity of the multidomain enzyme. RESULTS Screening experiments to e...

Hypertension is one of the major risk factors for cardiovascular disease. Although various drugs for its treatment have been synthesized, the occurring side effects have generated the need for natural interventions for the treatment and prevention of hypertension. Dietary intervention such as the administration of prebiotics has been seen as a highly acceptable approach. Prebiotics are indigest...

Levansucrases are bacterial extracellular enzymes that act on sucrose producing b-2,6-linked fructans of varied chain length. We summarize here our up-to-date results on (i) novel methods for the production of heterologous levansucrase proteins in Escherichia coli, (ii) biochemical characterization of the levansucrases encoded in the genome of a tomato and Arabidopsis pathogen Pseudomonas syrin...
