Impact of lipase-mediated hydrolysis of castor oil on γ-decalactone production ...

γ-Decalactone is an industrially interesting peach-like aroma compound that can be produced biotechnologically through the biotransformation of ricinoleic acid. Castor oil (CO) is the raw material most used as the ricinoleic acid source. The effect of different CO concentrations on the γ-decalactone production by Yarrowia lipolytica was investigated in batch processing, and 30 g L−1 was found to be the optimal ...

Immobilization of Yarrowia lipolytica for aroma production from castor oil

The main aim of this study was to compare different materials for Y. lipolytica immobilization that could be used in the production of γ-decalactone (a peach-like aroma) in order to prevent the toxic effect both of the substrate and the aroma upon the cells. Therefore, cells adsorption onto pieces of methyl polymethacrylate and of DupUM® was studied and further used in the biotransformation of castor oil into γ...

Enhancement of castor oil biotransformation into aroma by Yarrowia lipolytica m...

The food industry has a great interest in biotechnological production of γ- decalactone by Yarrowia lipolytica, due to its increasing consumers acceptability in comparison with similar products obtained by chemical synthesis. This yeast is able to produce γ-decalactone by transformation of a hydroxylated C18 fatty acid. However, lower yields of γ-decalactone were obtained (up to 4–5 gL-1), mainly due the degrad...

Lipase induction in Yarrowia lipolytica for castor oil hydrolysis and its effec...

γ-Decalactone is an aromatic compound of industrial interest, resulting from the biotransformation of ricinoleic acid, the major constituent of castor oil. In order to increase the availability of the substrate to the cells for the aroma production, castor oil previously hydrolyzed can be used. This hydrolysis may be promoted by enzymatic action, more specifically by lipases. In this work, the influence upon th...

γ-Decalactone is a peach-like flavour compound that can be obtained biotechnologically by the biotransformation of ricinoleic acid. Castor oil is the substrate most usually used in the biotechnological production of γ-decalactone and it needs to be hydrolyzed in order to release ricinoleic acid. That biotransformation can be carried out by various microorganisms, such as the non-conventional yeast Yarrowia li...

Biotransformação do óleo de rícino em aromas por Yarrowia lipolytica

Dissertação de mestrado integrado em Engenharia Biológica ; Os compostos aromáticos produzidos por processos biotecnológicos são cada vez mais aceites pelo mercado consumidor, por serem considerados naturais. Além disso, são processos de grande interesse devido aos elevados rendimentos que apresentam relativamente aos processos de extracção a partir de fontes naturais. A γ-decalactona é um composto aromático d...
