FEMA 3148 Chemical Properties,Usage,Production

  • Chemical Properties clear colorless to yellowish liquid
  • Chemical Properties Ethyl (2E,4Z)-2,4-Decadienoate has been identified in pears and has the typical aroma of Williams pears. Synthesis of ethyl (2E,4Z)-2,4-decadienoate starts from (Z)-1-heptenyl bromide, which is converted into a 1-heptenyllithium cuprate complex with lithium and copper iodide. Reaction with ethyl propiolate yields a mixture of 95% ethyl (2E,4Z)- and 5% ethyl (2E,4E)-2,4-decadienoate. Pure ethyl (2E,4Z)-2,4-decadienoate is obtained by fractional distillation. A biotechnological process for its preparation has been developed.
  • Chemical Properties Ethyl-trans-2, cis-4-decadienoate has a characteristic pear-like flavor and a light fruity aroma.
  • Occurrence Reported found in Bartlett pears, apple, grape, durian (Durio zibethinus), pear brandy, quince and spineless monkey orange (Strychnos madagasc).
  • Aroma threshold values Detection: 100 ppb. Aroma characteristics at 1.0%: sweet ripe pear, creamy and slightly fatty with fruity, green, waxy apple, fleshy nuances
  • Taste threshold values Taste characteristics at 5 ppm: ripe pear, green fruity, waxy apple, tropical notes, fatty golden delicious apple fleshy. Taste characteristics at 20 ppm: green, fruity, apple and pear with waxy tropical nuances.
  • Chemical Synthesis Synthetically via the lithium vinyl cuprates.
