2-Butenedioic acid (E)-, sodium salt - Reference Information
| Overview | sodium fumarate also known as sodium fumarate, sodium fumarate. White crystalline powder. Odorless, with a special taste. From the reaction of fumaric acid and sodium hydroxide made monosodium salt, recrystallization. Used as a sour flavor, such as powder cool drinks, canned fruits, cold food, fruit sauce, etc., also used as synthetic resin, mordant synthetic raw materials. As a new type of preservative, sodium fumarate is mainly used in aquatic products and meat products. It is widely used in foreign countries (Japan, South Korea, the United States). |
| uses | monosodium fumarate is used as a acidulant, a buffer, a flavoring agent, and an antioxidant aid. For the preparation of wine, cool drinks, confectionery products, powder juice, fruit cans, cold drinks, jam, jelly, etc. Preparation of bread, cookies and other complex leavening agent. Often with DL-malic acid, citric acid and other organic acids. |
| identification test | solubility soluble in water. According to the OT-42 method. 50mg of sample was taken in a test tube, resorcinol 2~3mg and sulfuric acid 1 ml were added, shaken, heated at 130 ℃ for 5min and then cooled. After being diluted to 5ml with water, 40% sodium hydroxide solution was added dropwise to make the solution alkaline. After cooling, the solution was diluted to 10ml with water. Blue fluorescence with green can be seen under UV light. In 0.5g of the sample, 10RNL of water was added, followed by boiling and dissolution. 2-3 drops of bromine test solution (TS-46) were added to the hot solution. The color of the bromine solution disappeared. According to IT-28 test sodium, positive. 1/30 aqueous solution pH 3~4. |
| content analysis | accurately weigh about 120g of a sample pre-dried at 0.3 °c for 4H, and dissolve in 30ml of water. Titration was performed with 0.1mol/L sodium hydroxide using two drops of phenolphthalein solution (TS-167) as an indicator. Each mL of 0.1mol/L sodium hydroxide corresponds to c4h3nao413.81 mg. |
| toxicity | ADI 0~6 mg/kg(FAO/WHO,2001). LD508g/kg (rat, oral). Safe for use in food (FDA,§ 172.350,2000). |
| usage limit | ADI 0~6 mg/kg(FAO/WHO,2001). Safe for use in food (FDA,§ 172.350,2000). FAO/ WHO(1984): 3g/kg of jam, jelly and orange peel jelly (used alone or in combination with fumaric acid, tartaric acid and its salts); PH-retaining agent (maintaining the pH at 2.8-3.5). |
