Rheological properties of salecan

Salecan, a soluble β-1,3-d-glucan produced by a salt-tolerant strain Agrobacterium sp. ZX09, has been the subject of considerable interest in recent years because of its multiple bioactivities and unusual rheological properties in solution. In this study, both succinyl and pyruvyl substituent groups on salecan were identified by an enzymatic hydrolysis following nuclear magnetic resonance (NMR), HPLC, and MS analysis. Like other microbial polysaccharides, Salecan has fascinating biological properties including antioxidation and nontoxicity, which are typically needed in food and pharmaceutical industries. 22–24 Additionally, Salecan contains plenty of hydroxyl functional groups located on its backbone, and consequently making it convenient to be chemically modified. A series of Salecan-containing hydrogels were developed by our laboratory recently. Salecan, a linear extracellular polysaccharide consisting of β-(1,3)-d-glucan, has potential applications in the food industry due to its excellent toxicological profile and rheological properties.

2013-03-20 · Salecan is an identified extracellular macromolecule from Agrobacterium sp. ZX09, mainly composed of β-(1→3)-D-glucosidic linkages as the main backbone structure, together with a small portion of α-(1→3)-D-glucosidic linkages . Salecan is a non-toxic and water-soluble beta-glucan with excellent rheological properties [21, 23]. 2017-10-15 · The rheological properties depend on the rigidity of the network, specially, the G’ increased with the increase of BAAm content.

In this study, both succinyl and pyruvyl substituent groups on salecan were identified by an enzymatic hydrolysis following nuclear magnetic resonance The research here provides an investigation of the rheological properties of Salecan solution over a wide range of shear rate (0.001–1000 s−1), frequency (0.1–100 rad/s), concentrations (0.3 Salecan, a linear extracellular polysaccharide consisting of β-(1,3)-d-glucan, has potential applications in the food industry due to its excellent toxicological profile and rheological properties. The research here provides an investigation of the rheological properties of Salecan solution over a wide range of shear rate (0.001–1000 s⁻¹), frequency (0.1–100 rad/s), concentrations (0.3%, 0.5%, 1.0% and 1.5%), temperature (5–95 °C) and pH Salecan is a novel soluble glucan produced by Agrobacterium sp. ZX09, displaying the ability to inhibit pancreatic amylase and reduce postprandial glucose. Salecan, a linear extracellular polysaccharide consisting of β-(1,3)-d-glucan, has potential applications in the food industry due to its excellent toxicological profile and rheological properties. Rheological gel characterization The rheological properties of chia gels were studied by shear, frequency and amplitude sweeps using a MCR 300 Rheometer (Anton Paar GmbH, Graz, Austria).

Rheology is the study of the flow of matter, primarily in a liquid or gas state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids. The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a The influence of concentration (0-0.5%, w/w) of gum tragacanth (GT) on thixotropy, dynamic, and creep-recovery rheological properties of ice cream mixes prepared with milk or water based were investigated. These properties were used to evaluate the viscoelastic behavior and internal structure of ice … Salecan, a linear extracellular polysaccharide consisting of β-(1,3)-d-glucan, has potential applications in the food industry due to its excellent toxicological profile and rheological properties.

Two Point Tests It is well established that the flow properties of fresh concrete at low shear rates approximate the Bingham model, expressed as follows: 2020-11-01 · More CH is an indication of the greater degree of hydration at higher curing temperatures which leads to enhancement of the rheological properties of the mixture due to the two following processes: i) the produced hydration products (e.g., CH, C–S–H, ettringite) fill up the voids, and also increase the solid volume fraction in the CPB system and ii) the consumption of water in the cement hydration process results in the reduced thickness of the adsorbed water film that Saliva is a complex biological fluid that cannot be effectively studied by conventional methods such as theFerranti-Shirley Viscometer. Testing with theWeissenberg Rheogoniometer shows that saliva is viscoelastic and that the dynamic viscosity falls from 400-0.1 Poise over the frequency range 2.5×10−3 to 10 Hertz. The calculated elastic contribution can be correlated with dry weight content Salecan is a recently identified water-soluble viscous extracellular β-1,3- d -glucan polysaccharide from an Agrobacterium species. It is a high-molecular-mass polymer (about 2 × 10 6 Da) and composed of a linear chain of glucosyl residues linked through a repeat unit of seven β- (1,3) and two α- (1,3) glucosidic bonds. Salecan is a novel water-soluble extracellular β-glucan produced by a salt-tolerant strain Agrobacterium sp.

have established relationships between the molecular structure of CMC and the rheological properties of the aqueous solutions over the CMC concentration range 0.5–3%. They reported that the molar mass and the polymer concentration are the governing parameters, whereas the degree of substitution (DS) has only a little influence affecting primarily the solubility.
