Chemical Properties:
  1. Metatartaric acid is an acidity regulator with molecular formula C6H10O11. It is a light yellow light porous solid with a complexing effect. It can combine with potassium or calcium ions of tartrate to form a soluble complex, so that tartrate is dissolved state. It is mostly used in canned grapes and wine to prevent the formation of tartrate precipitation.
  2. Slightly yellow light porous solid, odorless, insoluble in cold water, hygroscopic, and acidic in aqueous solution. It can form soluble complexes with potassium and calcium ions, and is easily decomposed into tartaric acid when exposed to excessive heat. ADI does not make special regulations (FCC, 1990).
  1. The RezexROA-OrganicAcid chromatographic column is used as the analytical column to establish a high performance liquid chromatography method for the detection of metatartaric acid in food. Through experiments, the effects of 9 common organic acids on the detection of food-grade metatartaric acid were investigated, and the results showed that under the test conditions, the 9 kinds of organic acids would not affect the detection of metatartaric acid. The recovery rate and precision of the method were analyzed and discussed.
  2. The results showed that the peak area and the standard solution showed a good linear relationship in the range of 0.1-20 mg/mL under the determined experimental conditions. The linear coefficient was greater than 0.999, and the recovery rate was 90.0%. ~100.0%, the coefficient of variation is less than 5.0%. The Chemicalbook application can be used to prepare a food dewaxing cleaning agent by combining 5-8% non-ionic polyacrylamide, 4% to 7% alkylphenol polyoxyethylene ether, and 10% to 15% food grade metatartaric acid.
  3. After the ionized water is mixed and refrigerated, 5% to 7% fruit acid, 6% to 8% methyl hydroxypropyl cellulose, 5% to 7% sodium dodecylbenzene sulfonate are mixed with heat. A cleaning agent can be prepared by mixing 5%~7% ethanol, 5~7% sodium bicarbonate solution with a mass concentration of 1~2% and the remaining deionized water, which can effectively remove food General dirt and hard impurities on the surface, especially the wax on the surface of the food can be removed.
