L-optimal mixture design was used for optimization of plant-based yoghurt produced by almond milk (AM) and Jerusalem artichoke milk (JAM). Lower L* values and titratable acidity were observed in plant-based yoghurts made from 75% Jerusalem artichoke milk and 25% almond milk compared to other yoghurts. Total phenolic contents and water holding capacity of plant-based yoghurts ranged from 49.68 to 61.78 mg GAE/100 g yoghurt and from 81.45 to 89.77%, respectively. The higher Jerusalem artichoke milk concentration in yogurt exhibited lower syneresis, higher water holding capacity and higher phenolic content. It was determined that the optimum concentration was 61.12% and 38.88% for Jerusalem artichoke milk and almond milk, respectively. The results of this study identified the key quality parameters of plant-based yoghurts made from different ratios of plant milks, that could play an important role in future plant-based product development. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.EnglishMixturesJerusalem artichokeKey quality parametersMilk concentrationOptimum concentrationOverall acceptabilityTitratable acidityTotal phenolic contentWater holding capacityDairiesArticle10.1007/s11694-021-00884-z
