| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| range of use | preservatives, fungicides. For fermented dairy products, yogurt, concentrated pineapple juice. 1, margarine usage: 1000mg/kg. 2, for the production process of pineapple juice with preservatives, usage: 1000mg/kg. 3, combined with sulfite, the use of more than 500mg/kg. |
| identification test | solubility: soluble in water, slightly insoluble in ethanol. According to the OT-42 method. Identification of calcium ammonium oxalate test solution (TS-24) was added to the saturated solution of the sample. The resulting white precipitate should be soluble in hydrochloric acid and insoluble in acetic acid. It is the same as the 3 and 4 items in the "Potassium Sorbate (07015)" identification test. |
| content analysis | accurately weigh (to mg) 0.25g of a dried sample. Dissolve in a 250ml flask containing 35ml of glacial acetic acid and 4 ml of acetic anhydride and warm to a solution. After cooling to room temperature, 2 drops of crystal violet test solution (TS-74) were added and titrated to the Blue Green end point with 0.1 mol/L perchloric acid in glacial acetic acid solution for at least 30s. At the same time into the blank titration and make necessary correction. Per ml of 0.1mol/L perchloric acid equivalent to this product (C12H14CaO4)13.12mg. |
| toxicity | ADI 0 to 25mg/kg (calculated as sorbic acid; Total ADI including sorbic acid and its salts; FAO/WHO,2001). GRAS(FDA,§ 182.3225,2000). |
| usage limit | FAO/WHO(1984,mg/kg): margarine 1000 (alone or with sorbic acid, benzoic acid and its salts, sorbic acid); Pineapple juice with preservatives 1000 (single or with sorbic acid, benzoic acid and its salts and sulfites dosage, but sulfites should not exceed 500, and used only in the manufacturing process). Lioda 9CFR,§ 318.7(2000):0.2% (not used in boiled sausages by weight and sorbic acid). EEC can be used for fermented dairy products, yogurt, concentrated pineapple juice, etc. |
| Use | used as preservative, fungicide, etc |
| production method | from calcium carbonate and sorbic acid. |
