Generation of thiols by biotransformation of cysteine-aldehyde conjugates with baker's yeast.

J. Agric. Food Chem. 51(12) , 3629-35, (2003)

Baker's yeast was shown to catalyze the transformation of cysteine-furfural conjugate into 2-furfurylthiol. The biotransformation's yield and kinetics were influenced by the reaction parameters such a...

Lipase-assisted generation of 2-methyl-3-furanthiol and 2-furfurylthiol from thioacetates.

J. Agric. Food Chem. 50(14) , 4087-90, (2002)

Enzymatic hydrolysis of S-3-(2-methylfuryl) thioacetate and S-2-furfuryl thioacetate using lipase from Candida rugosa produced 2-methyl-3-furanthiol and 2-furfurylthiol, respectively. When reactions w...

Effect of type of oil and addition of delta-tocopherol on model flavor compound stability during storage.
