ChEBI: Ethyl (2E,4Z)-deca-2,4-dienoate is a fatty acid ethyl ester resulting from the formal condensation of the carboxy group of (2E,4E)-deca-2,4-dienoic acid with the hydroxy group of ethanol. It has a role as a plant metabolite, a flavouring agent, a fragrance and a kairomone. It is functionally related to a (2E,4E)-deca-2,4-dienoic acid. | [Production Methods]
Stillingia oil is one of the fruits of the tallow tree native to China (Stillingia sebifera or Sapium sepiferum, Euphorbiaceae) vegetable fat. It contains about 5% of DDS in the form of glycerides by weight. Ethyl 2-trans-4-cis-decadienoate (DDSE) can be obtained from this by base-catalyzed transesterification with ethanol; however, in food law, this is not a natural process, so the product obtained cannot be called a natural flavouring.
A mixture of Stillingia oil (5 kg), natural ethanol (1.0 kg) and Novozym 435 (1.0 kg) was overlaid with nitrogen in a 20-liter glass vessel at 45 ° C and slowly stirred. The vessel was fitted with a water cooler to prevent losses and minimize evaporation. The approach was cancelled after an incubation period of 2 to 3 each Day. The filtered enzyme was added with fresh Stillingia oil and natural ethanol, and stirring was continued. All 10 cycles were performed, the content of Ethyl 2-trans-4-cis-decadienoate from the individual filtrates varied between 4.0 and 4.7% by weight.
