In this study, nutraceuticals based on antimicrobial ingredients (Artemisia absinthium water extract and essential oil (EO), Lactobacillus uvarum LUHS245 strain cultivated in a whey media, and blackcurrants juice (BCJ) preparation by-products were developed. In addition, two texture forming agents for nutraceutical preparations were tested (gelatin and agar). The developed nutraceutical ingredients showed antimicrobial properties: Artemisia absinthium EO (concentration 0.1%) inhibited

The best formulation consisted of the Artemisia absinthium EO, LUHS245, and BCP immobilised in agar and this formulation showed higher TPC content (by 2.1% higher), as well as higher overall acceptability (by 17.7% higher), compared with the formulation prepared using gelatin.
