Instant Active Dry Yeast

Instant Active Dry Yeast. Selected yeast strains dried in a special type dryer in less than 20 minutes at a temperature that will cause no loss in their fermentative activity (q.v.). The dry yeast, retaining over 87% of the gassing power (q.v.) of compressed yeast (q.v.), has its moisture content (q.v.) reduced to less than 5%, is packaged under a vacuum (q.v.) in a heat-sealed pouch, does not require refrigerated storage, and its loss of activity will normally not exceed 1% per month of storage.
