Simultaneous extraction of bioactive limonoid aglycones and glucoside from Citrus aurantium L. using hydrotropy.
Citrus limonoids were demonstrated to possess potential biological activities in reducing the risk of certain diseases. Limonoids are present in citrus fruits in the form of aglycones and glucosides. At present, limonoid aglycones and limonoid glucosides are extracted in multiple steps using different solvents. In order to understand their potential bioactivity, it may be beneficial to isolate ...
متن کاملImproved vanillin production in baker's yeast through in silico design
BACKGROUND Vanillin is one of the most widely used flavouring agents, originally obtained from cured seed pods of the vanilla orchid Vanilla planifolia. Currently vanillin is mostly produced via chemical synthesis. A de novo synthetic pathway for heterologous vanillin production from glucose has recently been implemented in baker's yeast, Saccharamyces cerevisiae. In this study we aimed at engi...
متن کاملEnzymatic synthesis of vanillin.
Due to increasing interest in natural vanillin, two enzymatic routes for the synthesis of vanillin were developed. The flavoprotein vanillyl alcohol oxidase (VAO) acts on a wide range of phenolic compounds and converts both creosol and vanillylamine to vanillin with high yield. The VAO-mediated conversion of creosol proceeds via a two-step process in which the initially formed vanillyl alcohol ...
متن کاملMicrobial Production of Vanillin
Vanilla (4-Hydroxy-3-methoxybenzaldehyde), an aromatic flavour compound, is one of the most commonly used food flavouring agents and is extracted from pods of Vanilla planifolia. It holds tremendous industrial applications in food, pharmaceuticals, beverages, perfumes and as nutraceuticals (1). Vanillin extracted from natural sources represents less than 1% of annual market demand and has a mar...
متن کاملBiocatalytic synthesis of vanillin.
The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was converted to the corresponding alcohol prod...
