Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 106 words
A process for the manufacture of an odorant and/or flavoring composition which comprises fermenting a compound of the formula ##STR14## wherein one of the dotted lines represents an additional bond, with a fungus selected from the group consisting of the genera Botryodioplodia, Botryosphaeria and Lasiodiplodia under aerobic conditions wherein (i) the pH is between 3 and 8; (ii) the temperature is between 15° C. and 35° C., (iii) the fermentation time is between 18 and 216 hours, (iv) the concentration of the substrate is from 0.5 grams per liter to 20 grams per liter, and (v) the fermentation product is separated from the culture by extraction.
Claim 2
Dependent Claim 106 words
A process for the manufacture of an odorant and/or flavoring composition which comprises fermenting a compound of the formula ##STR14## wherein one of the dotted lines represents an additional bond, with a fungus selected from the group consisting of the genera Botryodioplodia, Botryosphaeria and Lasiodiplodia under aerobic conditions wherein (i) the pH is between 3 and 8; (ii) the temperature is between 15° C. and 35° C., (iii) the fermentation time is between 18 and 216 hours, (iv) the concentration of the substrate is from 0.5 grams per liter to 20 grams per liter, and (v) the fermentation product is separated from the culture by extraction.
