Special Issue Information

Dear Colleagues,

Today, not only do consumers want to experiment with different flavors and ingredients in dairy products, but due to the rising number of life-threatening chronic illnesses in some countries, they are also more careful about their food selections. Moreover, consumers are more focused on healthy nutrition. As a result, the consumption of dairy foods with functional properties is increasing.

This Special Issue welcomes papers on the following topics, among others:

  • Bioactive compounds produced by advantageous bacteria, e.g., lactic acid bacteria, which exert advantageous effects on dairy food quality and safety, as well as human health.
  • Edible coatings as carriers for protective bacteria in dairy food applications.
  • Immobilization and encapsulation technologies for advantageous bacteria in dairy food applications.
  • Safety concerns and problem solving regarding dairy food production and shelf life.
  • Probiotic microorganisms in dairy food production.

Due to its low dietary impact and bioactive compounds, such as polyphenols and flavonoids, white kidney bean extract is an attractive raw material for fermented drinks. It can be utilized either on its own or blended with cow’s milk, offering a promising solution to help meet dairy product demand during mid-season shortages. Therefore, this study aimed to explore the physicochemical characteristics, sensory properties, and microbiological profile of fermented milk-like drinks made from white kidney bean extract, cow’s milk and their blends during 28 days of storage at 4 °C. Three blends of fermented milk-like drinks (FMLDs) were prepared from different ratios of cow’s milk (CM) and kidney bean extract (BE): FMLD1 (CM 30%:BE 70%); FMLD2 (CM 50%:BE 50%), FMLD3 (CM 70%:BE 30%), along with plain fermented kidney been extract (FBE; CM 0%:BE 100%), and plain fermented cow’s milk (FCM; CM 100%:BE 0%). The mixtures were pasteurized at 92 °C for 25 min and fermented with a probiotic-type starter culture (S. thermophilus, B. bifidum, L. acidophilus) at 43 °C. FBE exhibited the lowest levels of carbohydrates (2.14%), fat (0.11%), and protein (1.45%) compared to fermented cow’s milk and blends. The FBE and the fermented blends with a higher ratio of bean extract had lower viscosity and lactic acid contents, greener hue, more pronounced aftertaste and off-flavors, and received lower overall acceptability scores. Although the FCM had higher counts of S. thermophilus and L. acidophilus, the FBE displayed significantly higher counts of B. bifidum. This study demonstrated the potential of using white kidney bean extract and its blends with cow’s milk to create unique fermented products with a lower dietary impact, highlighting the importance of further optimizing the formulations to enhance sensory qualities and reduce the beany off-flavors in the products with added kidney bean extract.
