Tragacanth gumUsage

1.Unground Astragalus membranaceus gum is flat or thin, usually bending fragments or straight or spiral twisted strip fragments with thickness of 0.5-2.5mm.

2. White to light yellow, translucent, keratinous tissue, with short fissures. It is odorless, tasteless and slippery in taste. It is easier to crush when heated to 50 C. It is difficult to dissolve in water, but part of Astragalus sugar (bassorin) is easy to absorb water and blister into gelatinous material. 1g samples in 50ml water expand into smooth, thick, milky, non adherent gelatinous material. The solution of Astragalus membranaceus has a very high viscosity, with pH value of 5-6 and pH value of 5.

3. The viscosity of Astragalus membranaceus solution is the highest, and the pH value of Astragalus membranaceus solution is stable to the viscosity (up to pH value of 2). Add 1000 times of water and stir, then decompose into neutral solution. Hydrolysis produces galacturonic acid, galactose, arabinose, xylose and fucose, with a small amount of rhamnose and glucose (produced by trace starch and/or cellulose). It is insoluble in ethanol and insoluble in 60% (w/V) ethanol aqueous solution.

4. Thickener (especially for acidic food); stabilizer; emulsifier.
