The modern food industry is undergoing a rapid change with the trend of production of plant‐based food products that are more sustainable and have less impact on nature. Plant‐based dairy analogues have been increasingly popular due to their suitability for individuals with milk protein allergy or lactose intolerance and those preferring a plant‐based diet. Nevertheless, plant‐based products still have insufficient nutritional quality, undesirable structure, and earthy, green, and bean‐like flavor compared to dairy products. In addition, most plant‐based foods contain lesser amounts of essential nutrients, antinutrients limiting the bioavailability of some nutrients, and allergenic proteins. Novel processing technologies can be applied to have a homogeneous and stable structure. On the other hand, fermentation of plant‐based matrix with lactic acid bacteria can provide a solution to most of these problems. Additional nutrients can be produced and antinutrients can be degraded by bacterial metabolism, thereby increasing nutritional value. Allergenic proteins can be hydrolyzed reducing their immunoreactivity. In addition, fermentation has been found to reduce undesired flavors and to enhance various bioactivities of plant foods. However, the main challenge in the production of fermented plant‐based dairy analogues is to mimic familiar dairy‐like flavors by producing the major flavor compounds other than organic acids, yielding a flavor profile similar to those of fermented dairy products. Further studies are required for the improvement of the flavor of fermented plant‐based dairy analogues through the selection of special microbial cultures and formulations.

“…The milk kefir grains are small, round, and white and represent a symbiotic microbial ecosystem composed of lactic acid bacteria (LAB), yeast, and a small amount of acetic acid bacteria (AAB) distributed in an exopolysaccharide complex of kefiran. The genera of microorganisms found in milk kefir starter culture include, for example, the genera Lactobacillus , Lactococcus , Leuconostoc , Sacharomyces , and Kluyveromyces [ 16 , 17 , 18 ].…”

The purpose of this work was to evaluate the selected physicochemical, rheological, and sensory properties of a new whey-enriched carrot juice beverage (carrot juice: whey ratios of 100:0; 95:5; 85:15; 75:25; 65:35) fermented with milk or water kefir starter cultures over a storage period of 21 days (at 4 ± 1 °C). In general, for all tested samples, the values of total soluble solids, pH, and density decreased with increasing storage time. In contrast, the values of ethanol, degree of fermentation, and total dissolved solids increased with the prolongation of the storage time. Furthermore, it was found that all the model samples exhibited pseudoplastic behavior. Based on the sensory analysis performed, samples containing 25% (w/w) whey were evaluated as the most acceptable. Last but not least, the present study can serve as a basis for optimizing the manufacturing technology of a novel fermented vegetable beverage enriched with whey.

The research explored the influences of 2% and 4% heat‐treated fresh elderberry fruit mash supplement and 0.5% and 1% dried elderberry powder supplement before and after fermentation in kefir production on certain features of kefir beverage. Antioxidant activity, total monomeric anthocyanin, and total phenolic content were 16.69–75.67 (μmol TE/kg), 14.64–88.20 (mg cyn‐3‐gly/kg), and 167.94–531.33 mg GAE/kg in the samples during storage, respectively. Total phenolic content and antioxidant activity were higher in kefir samples produced with elderberry powder when compared to the other samples. It was determined that L* and b* increased with the decrease in the fruit supplement in kefir production, and L* and b* values were mostly higher in kefirs with fruit supplement before fermentation. The highest ACE inhibitor activity was observed in the kefir sample (1‐DEPre sample) with 1% dried elderberry supplement before fermentation on the first day of storage. It was determined that the general appreciation scores were above 3, and the samples produced mostly with dried elderberry powder were appreciated more when compared to the samples produced with fresh elderberry.
