426 3

Abstract:

Described is a method for augmenting or enhancing the aroma or taste of a raspberry flavored foodstuff or chewing gum comprising the step of intimately admixing with said foodstuff or chewing gum from 0. 02 parts per million up to about 300 parts per million based on total composition of a mixture of compounds prepared according to the process consisting essentially of the steps of: 1. reacting alpha pinene with an equimolar mixture of carbon monoxide and hydrogen at a pressure of 4,000 psig and a temperature in the range of 200. degree. -220. degree. C. whereby a mixture of aldehydes is formed; 2. distilling the mixture of aldehydes at a vapor temperature in the range of from 85. degree. C. up to 93. degree. C. and a pressure of from 3 mm/Hg. up to 4 mm/Hg.
