  • The objective of this study was to evaluate the quality characteristics of mozzarella cheese added wine concentrate. Mozzarella cheese was produced with different additives of wine concentrate which were 0~5%. The pH and the total acidity of the Cheese were analyzed. We also examined the radical scavenging activities for the antioxidant effect of samples and evaluated for their total polyphenol, and total flavonoid contents. The pH of Meoru wine cheese (6.28~6.37) was significantly higher and total acidity tended to decrease compared to that of the control. L* (lightness) of the wine cheese decreased with increasing amounts of wine concentrates whereas a* (redness) tended to increase. In the texture profile analysis, Meoru wine cheese showed higher values of hardness, gumminess, and chewiness. The ABTS radical scavenging activity of Meoru wine cheese showed the highest value when wine concentrate amounts were 2%. The DPPH radical scavenging activity was significantly increased in cheese added with wine concentrate. Total polyphenol contents and total flavonoid contents of Meoru wine cheese tended to increase with increasing amounts of wine concentrate. This research result highlights the positive influence of wine concentrate addition in cheese. Also, these results are expected to impact the experience programs in farm wineries.

  • This study evaluated the potential of utilizing the osmotic solution from dried mango processing as alternative raw material for mango wine making. Fermentation was carried out using two kinds of yeast strains Saccharomyces bayanus, Lalvin EC-1118 and Saccharomyces cerevisiae, Lalvin D-47 at 20$^{\circ}C$ for 28 days. Physicochemical analysis during fermentation was performed for each treatment and the resulting wine samples were analyzed for color, volatiles and sensory properties. Results of physicochemical analysis between the two fermenting samples as well as the wine samples show almost similar results regardless of the yeast strains. Wine color of sample wines after storage were not significantly different at p<0.05 and when compared with a commercial mango wine. From the volatile analysis, esters and alcohols constituted majority of the compounds. Production of several esters, alcohols, acids and terpenes were affected by yeast strain used in fermentation. Results of sensory analysis showed that wines fermented by S. bayanus EC-1118 strain was more acceptable although sensory scores between the treatments and the reference wine showed significant differences in all the attributes evaluated, except for bitterness. The utilization of osmotic solution from dried mango process could produce similar properties with existing commercial mango wines although there is still need for further work on the improvement of some sensory attributes of the mango wines.

  • In this study, effect of resveratrol concentration on wine taste was investigated. Content of resveratrol in 14 different wines were quantified using HPLC. The resveratrol concentrations in the Australian wine samples (grape species: Syrah) with 3 vintage years were analyzed and different concentrations of resveratrol were observed (2.89-3.84 mg/L). Variation in wine grape species with the same wine manufacturer (Chile, 2006) and variation in different manufacturing country of origin with same wine grape species (Cabernet Sauvignon, 2006) also produced the variations in resveratrol concentration. The preference analysis (color, aroma, taste,astringency and overall acceptability) of the sample wines were determined by 15 panelists using 5-point hedonic scale. When the analysis results of the resveratrol concentrations in the sample wines were compared with the preference analysis of sample wines, the resveratrol concentration in the wine produced the positive effects in the wine preference analysis in the factors of aroma, taste and color.
