Guar gum solubility in ethanol
WebThe guar gum (GG), the other most widely used galactomannan, with a high degree of galactose substitution in the mannan backbone (M/G ratio of ~ 2:1 and 40% of galactose content) is more soluble than LBG at ambient temperature. This variation in solubility is attributed to the extensive hydration of the galactose-rich regions. WebGuar gum is described by JECFA (2008) as a white to yellowish-white, nearly odourless, free-flowing powder insoluble in ethanol. According to EC specifications, guar gum is …

WebNational Center for Biotechnology Information Chemically, guar gum is an exo-polysaccharide composed of the sugars galactose and mannose. The backbone is a linear chain of β 1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side-branches. Guar gum has the ability to withstand temperatures of 80 °C (176 °F) for five minutes.
