Ethanol concentration of fermented broth by ohmic-assisted hydrodistillation

Fermented broth in tyrosinase- and melanogenesis inhibition.

Fermented broth has a long history of applications in the food, pharmaceutical and cosmetic industries. Recently, the use of fermented broth in skin care products is in ascendance. This review investigates the efficacy of fermented broth in inhibiting tyrosinase and melanogenesis. Possible active ingredients and hypopigmentation mechanisms of fermented broth are discussed, and potential applica...

Effect of Ethanol Concentration in Ultrasound Assisted Extraction of Glycyrrhizic Acid from Licorice Root

Induced by Inhibitory Ethanol Concentration

In oxygen-aerated non-growing cells a subinhibitory ethanol concentration (1 G/L) causes an H /K exchange. An inhibitory ethanol concentration (30 G/L) slows down acidification but + + has no effect on its extent. The transmembrane pH depends directly on the ethanol level in the medium and is not lowered at high ethanol concentrations. Changes in membrane potential induced by ethanol are also c...

Comparison of kinetic models of oil extraction from sandalwood by microwave-assisted hydrodistillation

Sandalwood and its oil, is one of the oldest known perfume materials and has a long history (more than 4000 years) of use as mentioned in Sanskrit manuscripts. Sandalwood oil plays an important role as an export commodity in many countries and its widely used in the food, perfumery and pharmaceuticals industries. The aim of this study is to know and verify the kinetics and mechanism of microwav...
