Understanding Instant Yeast
Before we dive into the topic of freezing instant yeast, it’s essential to understand what instant yeast is and how it differs from other types of yeast. Instant yeast, also known as rapid rise yeast or bread machine yeast, is a type of dry yeast that has been specially formulated to activate quickly and produce more carbon dioxide gas than active dry yeast. This makes it ideal for use in bread machines, as well as for baking bread and pastries that require a fast rise time.
How Instant Yeast Works
Instant yeast works by releasing enzymes that break down sugars into carbon dioxide gas and ethanol. This process, known as fermentation, is what causes dough to rise. Instant yeast is designed to activate quickly, typically within 5-10 minutes, and produces more carbon dioxide gas than active dry yeast. This makes it perfect for use in recipes that require a fast rise time, such as bread, rolls, and pastries.
The Shelf Life of Instant Yeast
Instant yeast, like all types of yeast, has a limited shelf life. When stored properly, instant yeast can last for up to 2 years at room temperature. However, its potency and effectiveness can decrease over time, especially if it’s exposed to heat, moisture, or light.
