- take about 6g of this product, add water 1 0 m l, stir, form mucus, should be amber.
- take this product about O . l g, centrifuge tube, add trifluoroacetic acid solution (6. 7-100)2ml, shake, plug, place at 120°C for 1 hour, centrifuge, and transfer the supernatant to a 50ml round-bottom flask, Add 10ml of water, and rotate and evaporate to dryness at 60°C under reduced pressure; the residue was dissolved by adding 2M l of 90% methanol solution, filtered, and the filtrate was taken as the test solution; 10mg of each of arabinose and galactose was taken, and 5ml of 90% methanol solution was added to dissolve, followed by shaking, as a mixed control solution. According to the thin layer chromatography (General 0502) test, the sample solution 5 ^ 1 and the mixed reference solution lO p U were respectively spotted on the same silica gel G thin layer plate, and 1 .6% sodium dihydrogen phosphate solution-butanol-acetone <10 : 40 : 50) for the development agent, the second development, the first time to expand the distance of about 10cm, the second time to expand the distance of about 15cm, take out, dry, spray with anisaldehyde solution (take anisaldehyde 0 .5ml, glacial acetic acid 10ml, methanol 85m and sulfuric acid 5M l mixed),UOaC heated to the spots show clear. The position and color of the galactose and arabinose spots of the test solution should be the same as the main spots of the control solution.

| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | arabinogalactan is a neutral polysaccharide composed of arabinose and galactose. This sugar is abundant in the xylem of conifers, especially in larch (Larix) up to 25%. It can be extracted from the wood flour with water. The content ratio of L-arabinose to D-galactose is generally 1:5 to 6. For a structure having many branches, an arabinose side chain of a β-1,3-bond is attached to the galactose chain of a β-1,3 or β-1,6-bond. |
| Use | arabinogalactan in soy milk, ice cream, ice cream, jelly, beverage, the dosage in the can is about 1% ~ 1.5%. Vinegar, soy sauce, vegetable oil, fruit juice, meat juice, vegetable juice and so on to form a stable emulsion thickener, the amount of 0.2% ~ 0.5% bread, cake, noodles, pasta, improve the utilization rate of raw materials, improve taste and flavor. Dosage 0.05%. Sauce, tomato sauce, mayonnaise, jam, cream, soy sauce, thickeners and stabilizers. thickeners, stabilizers, emulsifiers, compatibilizers, glazing agents, binders. Used for emulsifying essence; Seasoning base, sauce and pudding, etc. Instead of gum arabic. Also used for noodles, bread and sausage. |
