An Investigation on Some Compounds Effecting Aroma and Flavour of Strained Yoghurt Produced from Goat Milk

Abstract: Abstract:In this study, acetaldehyde, acetone, pH, titratable acidity, lactic acid, tyrosine and free fatty acids, namely butyric acid (C4), caproic acid(C6), caprylic acid (C8) and capric acid (C10) were taken into consideration affecting the variation in aroma and flavour scores (AFS) of strained yoghurt during the storage period of 60 days. AFS was negatively correlated with acetone (r=-0.832, P<0.01) and positively correlated with C4 (r=0.604, P<0.05), C8 (r=0.638, P<0.01) and C10(r=0.659, P<0.01). The res… Show more

“…In literature, a broad range of optimal acetaldehyde level exists, suggesting the characteristic aroma of the plain yoghurt. There are statements where acetaldehyde levels from 10 to 20 mg kg -1 are necessary for optimal taste and aroma, while there are reports implying acetaldehyde values from 21 to 41 mg kg -1 , are required for typical yoghurt flavor (Senel et al 2009). Yoghurt flavor formation occurs in three main stages; glycolysis, lipolysis and proteolysis, and the first phase of glycolysis is in fact the transformation phase in which the key aromatic yoghurt compounds like acetaldehyde, diacetyl, acetone and ethanol, are produced (Van Hylckama Vlieg et al 2007;Baran, 2012).…”
