Alginato di sodio

Descrizione:

Alginato di sodio è un polisaccaride di origine naturale derivato da alghe brune, composto principalmente da unità di acido manuronico e guluronico. È una polvere bianca o giallastra che è solubile in acqua, formando un gel viscoso all'idratazione. Questo biopolimero è noto per la sua capacità di formare gel in presenza di cationi bivalenti, come gli ioni di calcio, rendendolo prezioso in applicazioni alimentari, farmaceutiche e biomediche. Alginato di sodio è ampiamente utilizzato come agente addensante, stabilizzante ed emulsionante in vari prodotti alimentari, tra cui gelati e condimenti per insalate. Nell'industria farmaceutica, funge da agente di rilascio del farmaco ed è utilizzato in medicazioni per ferite grazie alla sua biocompatibilità e alla capacità di mantenere un ambiente umido. Inoltre, Alginato di sodio è riconosciuto per la sua bassa tossicità ed è generalmente considerato sicuro per il consumo. Le sue proprietà uniche, come la formazione di gel e la viscosità, lo rendono un ingrediente versatile in numerose applicazioni industriali.

Sodium alginate, viscosity 250 - 350 mPa.s

CAS: 9005-38-3

Sodium alginate is a natural polysaccharide that is extracted from seaweed and used as an emulsifier, thickener, and stabilizer in food products. It is also used to create a gel with water or other liquids. The viscosity of sodium alginate can be modified by adding sugar, glycosylation, or methylation. Click modification is used to introduce fluorine atoms into the polymer backbone. Sodium alginate may be modified by adding oligosaccharides or monosaccharides for use as a bio-sorbent in wastewater treatment plants.

Sodium alginate, high viscosity

CAS: 9005-38-3

Sodium salt of a polysaccharide obtained from the brown seaweeds (e.g. Laminaria hyperborea, Fucus vesiculosus, Ascophyllum nodosum). The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG). Alginates form strong gels with divalent metal cations and the egg box model has been used to describe this form of gelation. The main use for alginate is in textile printing as a thickener in the printing of cottons with reactive dyes. In the food industry it is used as a thickener and gelling agent.  Recently, it has been shown that ternary mixtures of Konjac glucomannan, Xanthan gum and Sodium alginate can form a non-covalently linked complex which exhibits enhanced rheological properties of value in, for example, functional foods.
