introduction | ethyl decanoate has a coconut aroma and is mainly used to prepare edible flavors. ethyl aliphatic carboxylic acids similar to this category, such as ethyl octoate, ethyl nonanoate and ethyl laurate are also used as spices. |
content analysis | accurately weigh about 1.3g of sample, and proceed according to method 1 in ester determination method (OT-18). The equivalent factor (e) in the calculation is 100.2. Or by non-polar column method in GT-10-4. |
toxicity | GRAS(FEMA). |
usage limit | FEMA(mg/kg): soft drink 2.1; Cold drink 4.5; Candy 8.3; Baked food 23; Pudding 5.3; Wine 3.0~10. Moderate limit (FDA § 172.515,2000). |
use | GB 2760-96 specifies food spices that are allowed to be used. Mainly used to prepare nuts, cheese, fruit wine, cognac and rum flavors. Ethyl decanoate has a coconut aroma and is mainly used to prepare edible flavors. Similar aliphatic ethyl carboxylic acids, such as ethyl octoate, ethyl nonanoate, and ethyl laurate are also used as spices. Sometimes commercial ethyl laurate refers to mixed esters. Caprylic acid (C8), capric acid (C10), lauric acid (C12), myristic acid (C14) and palmitic acid (C16) exist in coconut oil in the form of glycerides, of which the content of glycerides laurate is 45-51%. In the presence of sulfuric acid, ethanol and coconut oleic acid ester are used for transesterification reaction to obtain ethyl laurate, which is used to prepare perfume essence, soap essence, and edible essence. |
production method | prepared by esterification of decanoic acid and ethanol by conventional method. It is obtained by distillation after esterification of capric acid and absolute ethanol in the presence of hydrochloric acid or sulfuric acid. |
