| introduction | n-decanoic acid is a by-product of lauric acid produced by hydrolysis of lauric acid from laurel oil, coconut oil or Litsea cubeba oil. it is mainly used to produce decanoic acid esters, which are used as spices, humectants, plasticizers and food additives. |
| use | n-decanoic acid is a saturated fatty acid with medium carbon chain, which is found in a small amount in milk and goat milk. it is relatively high in tropical oils such as coconut oil (n-decanoic acid content is about 8%) and palm kernel oil (n-decanoic acid content is about 9%). n-decanoic acid and its esters are mainly used in food, plastic additives, medicine, pesticides, chemicals, aviation and other industries. They can be used as dairy, rum, Bailan licks and other flavors, food additives, lubricants, and moisturizers., Plasticizers, foaming agents, rust inhibitors, polymer modifiers, high and low temperature special oils, aviation oils, etc., have a wide range of applications and very optimistic market prospects. Used for essence, perfume and drug synthesis defoamer; GB 2760-96 stipulates that the heavy-duty ∑ fort spices allowed to be used are mainly used for dairy products, rum, white orchid and other flavors. Make esters and make juice spices. Chemical synthesis intermediates. It is mainly used to produce decanoic acid ester products, which are used as spices, wetting agents, plasticizers and food additives. |
| toxicity | natural fatty acid, non-toxic. Safe for use in food (FDA,§ 172.860.2000) |
| use limit | FEMA(mg/kg): soft drink 9.9, cold drink 3.1. Candy 4.5, baked goods 7.8, pudding 0.10~3.0, shortening |
| production method | coconut oil, laurel oil and Litsea cubeba oil are hydrolyzed to generate lauric acid, and at the same time by-product capric acid, the yield is 30% of lauric acid. See "Lauric Acid". It is obtained by fractionation of coconut oil fatty acids. |
