TL;DR: Inulin is a non-digestible carbohydrate that is contained in many vegetables, fruits and cereals as discussed by the authors, and it is widely used as an ingredient in functional foods, such as prebiotic, dietary fiber and low caloric value.
Abstract: Inulin is a non-digestible carbohydrate that is contained in many vegetables, fruits and cereals. It is industrially produced from the chicory's root (Cichorium intybus) and it is widely used as ingredient in functional foods. Inulin and its derivate compounds (oligofructose, fructooligosaccharides) are usually called fructans, as they are basically based on linear fructose chains. This review presents a description of inulin and its most common derivate compounds: chemical structure, natural sources, physic-chemical properties, technological functionality, industrial manufacturing, analytical method for determination and health benefits: prebiotic, dietary fiber, low caloric value, hypoglycemic action, enhancement of calcium and magnesium bioavailability. Potential benefits: lipid parameters regulation, reduction of colon cancer risk and others, improvement of immune response, intestinal disorders protection. From technological point of view, these compounds exhibit a variety of properties: thickener, emulsifier, gel forming, sugar and fat substitute, humectant, freezing point depression. Inulin and derivates are been used in pharmaceutical, chemical and processing industry as technological additives and excipients. They are also been used for animal feeding. They are been considered as "bioactive" compounds to be proposed as future packaging material. Fructans are proposed to be classified as "functional fiber", according to recent concepts based on physiological effects on individuals. This review of inulin and its derivates was useful to show the broad boundaries of these compounds in the food industry and why they may be considered as key ingredients in the expanding functional food market.

TL;DR: In this article, the effect of clay type and loading on the time scale of the relaxation process of the NR matrix has been studied by dielectric relaxation spectroscopy, and a new mode, slower than the segmental dynamics but faster than the normal mode associated with the chain dynamics, has been observed for both vulcanized and nonvulcanized nanocomposites with fillers having high levels of intercalation.
Abstract: The segmental chain dynamics in nonvulcanized and vulcanized natural rubber/layered silicate nanocomposites has been studied by dielectric relaxation spectroscopy. Special consideration has been devoted to the effect of clay type and loading on the time scale of the relaxation processes. Results reveal that the type and concentration of clay do not have an effect on the segmental mode of the NR matrix, while the vulcanization reaction slows down the segmental dynamics. A new mode, slower than the segmental dynamics but faster than the normal mode associated with the chain dynamics, has been observed for both vulcanized and nonvulcanized nanocomposites with fillers having high levels of intercalation. We attribute the new mode to a restricted segmental dynamics of natural rubber chains located at the clay/rubber interfacial regions.

TL;DR: This work provides a framework to perform prediction in some types of binary random elds by using a Bayesian approach to map a binary outcome over a bounded region D of the plane and provides measures of prediction uncertainty amenable for binary outcomes.

TL;DR: The lamellar thickness, as well as the melting point, was found to have a small decreasing dependence with the molecular weight of the samples, and this value is in the same range as those obtained previously for similar linear polyesters.
