How Humidity Affects Baking Yeast and Leaveners
Bakeries, breweries and those who appreciate bread owe a debt of gratitude to this single-celled fungus that feeds on sugars to produce alcohol and carbon dioxide gas – raising dough! Yeast can be purchased as either compressed cakes or dry granules and stored properly can last two years; their effectiveness depends on factors like temperature, humidity and other environmental considerations. Temperature Yeast, the single-celled organism Saccharomyces cerevisiae that gives bread its rise and flavor, requires warmth and moisture for its survival. When these conditions exist, yeast releases carbon dioxide gas that causes dough to rise while improving texture, grain size,
