Can I use dead yeast?

You can use "dead" yeast in baking only if it's still partially active; if it's truly dead (no bubbling in a warm, sugary water test), it won't leaven bread but won't harm you, though it can impart a beer-like flavor, so it's best to discard truly dead yeast for baking and use it for compost or ant bait instead.

What is the side effect of expired yeast?

Using expired yeast results in reduced rising power, meaning your dough will rise slowly, poorly, or not at all, leading to dense, tough bread; it's usually still safe to eat but ineffective, so you should always proof it first by mixing with warm water and sugar to check if it foams up, and if it doesn't, toss it and use fresh yeast or a quick bread recipe.

Can active dry yeast sit too long?

Yes, active dry yeast can sit too long, both in its dry form (losing potency over time, especially after opening and exposure to air/heat) and after being proofed (losing vitality if left foamy for too long), leading to poor dough rise; always test its activity with warm water and sugar, and store opened yeast in the fridge or freezer to slow down expiration. 

How do bakeries get their bread so soft?

Bakeries make bread soft using fats, sugars, milk solids, and dough conditioners (emulsifiers, enzymes) to tenderize gluten and retain moisture, plus techniques like the tangzhong method (cooked flour paste) or adding potato/starch for a tender crumb, while commercial bread uses chemical additives like azodicarbonamide (ADA) for extra fluffiness and shelf life, ensuring a consistently soft, moist texture.
