The effects of various storage conditions on changes in the colour of an alcoholic drink known as "tuzemák"

Popis výsledku v původním jazyce

The present work examines the effects of storage conditions on the colour stability of Tuzemák, a typical Czech alcoholic drink. The measurements were carried out over a period of 24 months. Samples were stored in bottles made of dark and clear glass and were stored in two different temperature modes, 20 oC and 6 oC, with light allowed in, light not allowed in, and lighting with an LED bulb. During the storage period, the dynamics of the colour changes were determined using a Konica Minolta CM 3500d spectrophotometer. The measured value was lightness L*(D65). The results confirmed that storage conditions have a significant influence and effect on the stability and permanence of the colour of alcoholic drinks. In the samples, the parameter L*(D65) ranged between 83.32 and 92.22. Storage with no light (in the dark) at a low temperature (+- 6 oC) and using a dark bottle as a container was found to be the best combination for ensuring maximum colour stability. The influence of light and temperature on storage was less pronounced in dark bottles than in the clear bottles where the lightening of the product was more obvious.
