The effect of germination on flavor attributes of six Vicia faba L. cultivars (Najeh, Saber, Chourouk, Local, Bachar and Badii) was assessed using HS-SPME/GC-MS technique. Of all aroma compounds identified, 37 were emitted by unsprouted (19) and sprouted (28) seeds. However, 32 active odors were characterized in the flours obtained from unsprouted (18) and sprouted (28) grains. The total identification percentages of the volatiles ranged from 94.2% to 99.9%. The volatiles were classified into five chem. classes i.e., monoterpene hydrocarbons (MH), oxygenated monoterpenes (OM), sesquiterpene hydrocarbons (STH), apocarotenes (AP), and non-terpene derivatives (NTD). Germination induced the formation of OM, increased NTD, and decreased MH in sprouted seeds, with the sole exception of the Najeh cultivar. In flours, the most representative chem. classes was NTD followed by MH, again with the exception of the for Najeh cultivar, which emitted much more STH. In addition, an increase in beany flavors in sprouted faba beans has been noted. The milling reduced the percentage of nonanal, considered one of the beany flavors of faba beans. However, when the germinated seeds were minced, a new beany flavor constituent appeared, 2-pentyl furan. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Category: esters-buliding-blocks).
Octyl acetate (cas: 112-14-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: esters-buliding-blocks
