introduction | ethyl octoate is colorless and transparent liquid, occasionally slightly yellow, with pineapple-like fragrance and sweet taste. Boiling point 208.5 ℃. Insoluble in water, but easily soluble in ethanol, ether, chloroform, almost insoluble in propylene glycol. It forms an azeotropic mixture with water, and the content is 18% at the azeotropic point of 98.25 ℃. It is made of caprylic acid and ethanol, catalyzed by a small amount of concentrated sulfuric acid, and heated. It can be used as a flavoring agent for orange, strawberry, pineapple and other spices. |
application | sucrose ester fatty acid as a sucrose derivative is a safe, non-toxic, odorless and pollution-free with excellent performance. Polyol nonionic surfactant with no side effects, no stimulation, good stability and complete biodegradation. It can effectively reduce the surface tension of water, and has excellent performance in wetting force, dispersion force, solubilization, foaming force, emulsification force, detergency force, etc. At the same time, it also has insecticidal and antibacterial properties. Therefore, it has strong adaptability and wide application range. At present, it has been widely used in food industry, daily chemical industry, pharmaceutical industry, textile, agriculture and animal husbandry and other fields, especially as emulsifier, dispersant, foaming agent, wetting agent and cleaning agent in food industry. Cosmetics and detergents in daily chemical industry, etc. |
content analysis | accurately weigh about 1.1g of sample and quantify it according to method 2 in ester content determination method (OT-18). The equivalent factor (e) in its calculation is 86.13. It should be determined by non-polar column method in GT-10-4. |
toxicity | LD5025960mg/kg (rat, oral). |
usage limit | FEMA(mg/kg): soft drink 4.1; Cold drink 2.4; Candy 9.0; Baked food 11; Pudding 0.10~2.7; Gum candy 4.0~60. Moderate limit (FDA § 172.515,2000). |
Use | Used as food flavoring agent GB 2760-96 specifies as allowed edible spices. Mainly used to prepare milk, cheese, apple and pineapple wine, brandy, rum and other flavors. It is rarely used in daily cosmetic flavors, but it can be used in moderation in the new flavor that requires fruity and bouquet. It can be used in large quantities for edible flavors, such as apricots, apples, oranges, grapes, nuts, raw pears, pineapples, bananas, strawberries, brandy, rum, etc. This product has a white and half fragrance aroma, which is used to prepare edible essence. Used for perfume preparation organic synthesis. Prepare spices. |
production method | is obtained by esterification of caprylic acid and ethanol. Add caprylic acid, ethanol and a small amount of concentrated sulfuric acid to the reaction pot, heat and reflux for several hours, then neutralize with sodium hydroxide solution, and then distill. It is obtained by heating and esterification of ethanol and caprylic acid under sulfuric acid catalysis and distillation. |
