Opis:
Shaping the quality of food aroma as an important factor in product selection and acceptance is still the current goal of the conducted scientific research. Many studies indicate that the quality of aroma in the hedonistic category depends on the volatility and concentration of odorants that can cause extremely desirable or undesirable sensory sensations. In turn, indicators for assessing the impact of selected factors affecting the quality of food aroma are retention and the odor activity value (OAV). Food flavorings are preferred because of their standardized quality, strength of aroma and sterility, while super-spices due to their multifunctionality. The attention is also drawn to the growing interest in food emulsions as universal carriers of aroma compounds, and the possibility of shaping their stability in foods, especially those with reduced fat content, by appropriate selection of natural emulsifiers and/or thickeners.

Opis:
Volatile compounds are very important to the flavour and quality of the wine. The study aimed to determine the effect of grape variety (Rondo and Zweigelt), yeast, malolactic fermentation (MLF) and yeast×MLF interaction on the content of volatile compounds in red wines. The wines were produced by sequential inoculation with five commercial yeast strains and a commercial lactic acid bacteria (LAB) strain (induced malolactic fermentation) as well as by inoculation with five commercial yeast strains and without LAB inoculation (spontaneous malolactic fermentation). The volatile compounds were determined by headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME-GC/MS). Forty-six volatile compounds belonging to alcohols, esters, acids, aldehydes, ketones, furan compounds, sulfur compounds and volatile phenols were identified in the wines. The grape variety was the factor with a significant impact on the highest number of volatile compounds, 32 out of 46. Furthermore, 7 compounds were affected by yeast, 10 by MLF and only 3 by yeast×MLF interaction. Characteristic bands in Fourier transform infrared (FTIR) spectra were assigned to the vibrations of functional groups of volatile compounds. The whole FTIR spectra were analysed in detail; three characteristic spectral ranges for different classes of volatile compounds such as 3650-2700, 1750-1500, and below 1500 cm-1 were shown. The most remarkable spectral changes were observed for the last two areas.
