Saccharomyces cerevisiae

Saccharomyces cerevisiae (CAS 68876-77-7), commonly known as baker's yeast or budding yeast, is a commercially cultivated microorganism used in food production, fermentation, and biotechnology.

Where is Saccharomyces cerevisiae used?

• Baked goods: CO₂ generation through sugar fermentation, producing rise and crumb structure in bread, rolls, and pastries
• Beer, wine, and spirits: conversion of fermentable sugars into ethanol and flavor compounds
• Soups, sauces, and seasoning blends: yeast extract delivering savory flavor profiles and natural glutamates
• Animal feed: inactivated forms supply B-vitamins, amino acids, beta-glucans supporting gut health and immune function
• It drives leavening, fermentation, and flavor development in consumer and industrial end products.

Commercial specifications

• Active dry yeast, instant dry yeast, and compressed fresh yeast
• Packaging from retail sachets to bulk industrial formats
