Yeast Extract (Autolysate) is a yeast extract made by autolyzing Saccharomyces cerevisiae. In place of or in addition to beef extract, this is employed in culture medium as a great stimulant of bacterial growth. A high quality source of amino acids, peptides, vitamins, and other vital nutrients is required for a variety of industrial fermentation processes. Yeast Extract (Autolysate) is guaranteed to be free of GMOs and substances derived from animals. Where a low Amino Nitrogen content is required, it is very effective.
Peptone from yeast is nonmammalian peptone and is completely free from any harmful substances that may lead to disorder such as TSE/BSE which is caused due to infectious protein.
Description: It is derived from Autolysis (Process) of Brewers Yeast (Saccharomyces cerevisiae) further purified to produce free flowing spray dried powder with characteristic proteinous odour.
Application:Source of organic nitrogen recommended in Culture Media for Analytical microbiology, Diagnostics, Laboratory Reagent and Industrial fermentation.

FAQs of Yeast Extract (Autolysate):
Q: How should Yeast Extract (Autolysate) be used in food and fermentation applications?
A: Yeast Extract (Autolysate) can be directly added as a powder or granule to recipes or fermentation media. Its high solubility ensures even distribution when dissolved in water, making it ideal for soups, sauces, seasonings, fermentation broths, microbiology media, and animal feed supplements.
Q: What are the benefits of using this yeast extract as a flavor and nutrient source?
A: Rich in protein and nutrients, this yeast extract acts as an effective flavor enhancer, bringing a savory, umami taste while also supporting microbial growth in fermentations. Its natural enzymes help improve fermentation efficiency and contribute to robust product yields.
Q: What storage conditions are recommended for maintaining product quality?
A: Store the yeast extract in a cool, dry place, away from moisture and direct sunlight. Keep it in its original, unopened multi-layer laminated bags to preserve freshness and potency, ensuring a shelf life of up to 24 months.
Q: When is the best temperature range for using yeast extract in fermentation processes?
A: For optimal fermentation results, use this product within the temperature range of 25C to 30C. This encourages maximum enzymatic activity and nutrient availability for fermenting microorganisms.
Q: Where does your yeast extract source its proteins and enzymes from?
A: The proteins and enzymes are naturally derived from edible yeast via the autolysis process, ensuring high nutrient content and enzymatic activity without the addition of synthetic substances.
Q: What is the process behind the production of your yeast extract (autolysate)?
A: Yeast extract (autolysate) is manufactured through controlled autolysis, where yeast cells self-digest, releasing valuable proteins, amino acids, and enzymes. The extract is then carefully dried to produce a powder or granule with consistent quality and solubility.
