Guanosine 5'-monophosphate disodium salt Chemical Properties,Uses,Production

Identification test

UV absorbance: A 1/50000 sample solution was prepared with 0.01 mol/L hydrochloric acid solution, which had a maximum absorbance at a wavelength of 256 nm ± 2 nm. A250/A260 ratio is at the range of 0.95 to 1.03, and A280/A260 ratio is at the range of 0.63 to 0.71.
Ribose test exhibits positive result. Take 3 mL of 0.03% sample solution, add 0.2 mL of the ethanol solution of 10% dihydroxy toluene, and 3 mL 0.1% ammonium ferric sulfate hydrochloric acid (TS-100), heat in water bath for 10 min, the color of the solution should be green.
Organic phosphate test is positive. Take 5 mL of 1% sample solution plus 2 mL of magnesium oxide mixture solution (TS-133), there should be no precipitation occurred. Further add 7 mL of nitric acid and boil for 10min, neutralize with sodium hydroxide solution (TS-224) and should exhibit phosphate reaction (IT-26).
The sodium salt test was positive (IT-28).
Solubility: it is soluble in water, slightly soluble in ethanol but almost insoluble in acetone and ether (OT-42).

Content analysis

Accurately weigh 500 mg of sample and dissolve with 0.01 mol/L hydrochloric acid, and add the volume up to 1000 ml. Take 10 mL of this solution, and then add 0.01mol/L hydrochloric acid to a final volume of 250 ml and mix. Use 0.01mol/L hydrochloric acid as a control, place it in 1 cm cuvette and measure the absorbance A under the wavelength of 260nm and then calculated as follows:
Amount (%) = A/289.8 × 250,000/Sample amount (mg) × 100/(100-Moisture (%)) × 100

Toxicity

ADI is not subject to special provision (FAO/WHO, 2001).
LD50:10 mg/kg (rat, oral). After chronic test feeding of 0.1% to 1% feed for 6 months, weight and tissue get no abnormal changes.
It can be safely used in food products (FDA, §172.530, 2000).
EEC-HACSG provides that it should not be used for infant food.

Usage limit

GB 2760-96: all kinds of food, take GMP limit.
FAO WHO: luncheon meat, ham, bacon, etc., 500 mg kg (in guanosine), broth and soup, GMP.

Chemical properties

It appears as colorless to white crystalline or crystalline powder, usually containing 7 molecules of crystal water, being odorless, having unique flavor similar to mushrooms. Melting point is not obvious. It undergoes browning under 240 ℃ and decomposition under 250 ℃. It is stable against acid, alkali, salt and heat. It has strong moisture absorption property and is easily soluble in water (25 ℃, 25%). The pH value of its 5% aqueous solution is 7.0 to 8.5, being slightly soluble in ethanol, acetone and ether. Mouse: oral LD50: 10g/kg, ADI does not require special rule(FAO/WHO, 1994).

Uses

Guanylate sodium is allowed flavoring agent allowed at home and abroad, often used together with MSG and sodium inosinate. When mixed for usage, it has multiplication effect on the taste. It can be used for all types of food and should be subject to appropriate use according to production needs.
It is mainly used as condiments, being a new generation food by freshener.
It is a kind of flavor agent with mushrooms flavor. It is often used in conjunction with sodium glutamate (adding amount is 1%~5%), there is a very significant increase in freshener effect.

Preparation

The production methods of guanylic acid mainly include enzymatic hydrolysis and fermentation method. In the fermentation method, there are two-step method and combination method with biosynthesis and chemical synthesis, two kinds which are of industrial significance.
(1) Ribonucleic acid (RNA) hydrolysis method. See the production method of 5'-inosinic acid disodium.
(2) Two-step method. Take glucose as the carbon source and ferment with the Bacillus subtilis mutant to obtain the guanosine. The production level was 10.5 g/L. Then guanosine, in pyridine solution, is acidified with phosphorus oxychloride phosphate to obtain guanylate.
(3) Biosynthesis and chemical synthesis.
At pH=7, apply Bacillus megaterium (No. 336) for fermentation of glucose (8%) for 90 h at pH = 7, producing 15 g/L 5-amino-4-carboxamide nucleoside (AICAr); then extract by ion exchange, followed by concentration and drying to be dissolved in methanol containing NaOH. Add carbon disulfide for co-heating so that it is converted into 2-thioglycoside; It is finally oxidized with hydrogen peroxide; add excess ammonia and heat to obtain guanosine which is further converted to guanylate through phosphorylation.
