Synthesis of Cyanoethyl Inulin, Aminopropyl Inulin and Carboxyethyl Inulin

Starch - Stärke, 1996
AbstractInulin was cyanoethylated by reaction with acrylonitrile in the presence of aqueous sodium hydroxide. Products with a degree of substution (ds) from 0.2 to 1.6 were prepared. The materials were analyzed using NMR spectroscopy and GPC analysis.

Carboxymethylation of inulin

Carbohydrate Research, 1995
Inulin was carboxymethylated in aqueous alkaline medium with monochloroacetic acid as the reagent. The degree of substitution of the reaction product was determined by titration, LC analysis and 13C NMR spectroscopy. Carboxymethylinulin with a degree of substitution between 0.2 and 1 was obtained depending on the molar ratio of inulin-monochloroacetic ...

Studies on the physicochemical properties of inulin and inulin oligomers

Food Chemistry, 2000
Abstract Inulin, Raftiline® ST, Raftilose® P and oligofructose in aqueous solutions were investigated at 2.5, 5, 10, 15, 17.5, 20 and 25 g of solute in 100 g of water by physicochemical measurements in order to obtain molecular weights, reducing activities, apparent specific volumes, isentropic apparent specific compressibilities, and 1 H-NMR pulse ...

Synthesis of Carbamoylethyl Inulin and Carboxyethyl Inulin

Starch - Stärke, 1998
Inulin etherified with carbamoylethyl groups and with carboxyethyl groups is described. Both materials were prepared by hydrolysis of the nitriles of cyanoethyl inulin, which was obtained from reaction of inulin with acrylonitrile.

The adjuvanticity of gamma inulin

Immunology & Cell Biology, 1988
SummaryGamma‐inulin (g‐IN) is a polymorph identified as the active component of inulin preparations that specifically activates the alternative pathway of complement (APC). The APC is central to many leucocyte functions, including B cell activation. We show here that g‐IN, when formulated as a pure, endotoxin‐free, fine suspension insoluble at 37°C and

Measurement of inulin: development

Annales de biologie clinique, 2011
Inulin clearance is still considered as the gold standard method to measure glomerular filtration rate. This method has been proposed in thirties by Smith and Shannon but the inulin measurement method still remains complex. Interferences, notably with the glucose, must also be considered.

Permeability of placenta to inulin

American Journal of Obstetrics and Gynecology, 1988
Inulin was administered to eight volunteer patients at term gestation over a period of 3 hours before cesarean section. Inulin concentrations were repeatedly measured in maternal plasma, in fetal plasma, and in amniotic fluid at the time of delivery. Total inulin uptake of the conceptus was taken to be the sum of the inulin in the amniotic fluid and in

Single crystals of inulin

International Journal of Biological Macromolecules, 1996
Lamellar crystals of inulin were grown by crystallizing sharp fractions of low molecular weight inulin from dilute aqueous ethanol solutions. The crystals were analyzed using three-dimensional electron diffraction and X-ray powder diagrams. Two crystalline polymorphs were observed, depending on the hydration conditions: a hydrated form which indexed on

Mechanochemical depolymerization of inulin

Carbohydrate Research, 2018
Although chemical reactions driven by mechanical force is emerging as a promising tool in the field of physical sciences, its applications in the area of food sciences are not reported. In this paper, we propose ball milling as an efficient tool for the controlled generation of fructooligosaccharide (FOS) mixtures from inulin with a degree of ...
