description | This study focused on the determination of quality characteristics of homemade organic vinegars (apple, red hawthorn and yellow hawthorn) which were produced with double fermentation (ethyl alcohol and acetic acid fermentation) method by spectroscopy (UV/Fourier transform infrared) and rheology technique. These absorbance peak values are associated with organic acids and phenolic compounds were determined as an important parameter in the quality evaluation of vinegars. It was determined that the flow curves of all vinegars are compatible with the non-Newtonian flow, which is the behaviour of thickening (dilatant) fluids. From the obtained results, it was thought that the antioxidant and anti-bacterial effect of yellow hawthorn vinegar would be higher due to its higher acetic acid and phenolic compound content compared to the others. |
