The study assessed the effects of soaking hard cheeses and cheese slices in blackcurrant wine on their antioxidant, microbiological, and sensory properties. Soaking increased weekly, the phenolic content by 40.86 ± 0.3 mg GAE/100 g (gallic acid equivalent) of cheese, and their reached the maximum ethanol content of 1.29 ± 0.08 g/100 g. Soaking reduced the amount of foodborne pathogenic bacteria, enhancing microbiological safety. The lactic acid bacteria count significantly decreased during soaking time. The sensory evaluation shows that 45 % of tasters preferred the soaked cheese. Positive correlations were observed between taste and color (in whole-soaked cheese), while negative correlations were revealed among color, smell, and texture (in soaked quarter cheese). The results suggest that blackcurrant wine, containing a wealth of bioactive constituents, has the capacity to augment the favorable attributes of cheese and presents prospects for developing a novel gastronomic offering.

Cheese consumption is steadily increasing worldwide, with a growing interest in cheese enriched with bioactive substances, including antioxidants. This study investigated the impact of adding blackcurrant wine to the curd (IC), enriching the curd with blackcurrant wine by soaking and ripening in salted blackcurrant wine (IOC), and cheese soaked and ripened in blackcurrant wine with 5% (w/w) NaCl (OC). The curd and added wine weight ratio (1.5:1, 3:1) effects were also studied. Physicochemical (dry matter, polyphenol content, antioxidant activity, radical-scavenging activity, anthocyanin content like delphinidin-3-rutoside and cyanidin-3-rutoside, ethanol content), microbiological, and sensory properties of the cheeses were evaluated. The results indicated that a week of soaking is sufficient to achieve the maximum antioxidant capacity and polyphenol content of the cheese. From a technological and sensory point of view, a 1.5:1 ratio of blackcurrant wine to curd was better. The maximum transfer rate of delphinidin-3-rutoside from wine was the most pronounced in IOC samples (20.44%). Blackcurrant wine inhibited the growth of lactic acid bacteria, and a longer soaking time can hinder the ripening process of cheese. During tasting, among the treated cheese, IC samples received the highest average acceptance scores for appearance, texture, creaminess, flavor, saltiness, bitterness, freshness and overall impressions.
