The unique aroma and taste of yeast extract can effectively neutralize unpleasant tastes such as bitterness and sourness and strengthen the pleasant mouthfeel and make it more pleasant. By adding yeast extract in the final products, it is possible to create ideal sweetness, desired taste and rich nutritional contents in drinks. Yeast extract masks off-flavors such as citric acid and the lingering effect of sweeteners to reveal the original fruit flavor of fruit juices. According to studies, the combined use of yeast extract and a sweetener has helped to reduce sugar consumption from 30% to 5% without reducing the taste.
