More about Compressed Yeast
Compressed yeast often referred to as “wet yeast” or “fresh yeast” is the traditional baker’s yeast product. At the end of the yeast fermentation, the yeast broth is washed repeatedly with cold water to remove any residual fermentation additives. The yeast cells are then concentrated to form a light tan, semi-viscous liquid called cream. Cream yeast contains approximately 18% yeast solids. The cream is further dewatered by passing it through a rotary vacuum filter to form a semi-solid cake that contains approximately 30% yeast solids. This cake is typically crumbled directly into a 10Kg polythene liner with an outer carton and sold as crumbled compressed yeast.
Crumbled yeast may be added directly to the mixer on top of dry ingredients or slurred in water with other ingredients to form a preferment. Compressed yeast has excellent leavening properties in all types of dough systems and, since it is perishable, should be stored under refrigeration at all times prior use.
The 10Kg carton of the wet yeast should not be left out of the cooler for an extended period of time once opened. Partially empty cartons should have their polythene liners rolled down tightly to the level of the remaining yeast to minimize exposure to oxygen and returned to the cooler. When properly handled, the shelf life of the wet yeast is about two weeks.
Technical Data Sheet
Sifa Fresh Wet yeast.
A leavening agent comprised of living plant cells derived from a pure culture of Saccharomyces cerevisiae, grown to appropriate protein and phosphate levels for optimum activity.
Saccharomyces cerevisiae grown in clarified molasses and nutrients.
Store under constant refrigeration making sure the yeast temperature does not exceed 10°C. Stored yeast should always be wrapped and not exposed to air. Yeast should be properly rotated, using older supplies first.
Shelf life depends upon storage conditions (temperature and humidity), as well as storage time; therefore, precise limits cannot be set. Customers can store this yeast as temperatures of up to 10°C for short periods of time. However, even under optimum conditions of about 4°C, this yeast has a maximum stability period of two weeks.
10Kg Polythene lined carton boxes.
All yeast-leavened baked goods.
– Laboratory controlled fermentation for consistent uniformity.
– Compatible with all fermentation processes.
