Make a great impact in your baking and bread products with our Instant Dry Yeast. Yeast fermentation happens when the yeast cells feed on sugar, the food of choice for yeast. Yeast fermentation in a dough has three functions in bread making. Firstly, in rising the dough, yeast fermentation makes carbon dioxide, a gas responsible for stretching and expanding the dough like a balloon. Secondly, it helps in dough development. Other compounds formed during yeast fermentation make the flour tougher so that it can capture and hold the carbon dioxide gas that the yeast produces. Last but not the least it generates the flavor, aroma and texture. Yeast fermentation also produces these mouth watering, sensory and, physical attributes that you expect from yeast-raised products.
