Bread is one of the most popular foods around the world.Typically made from wheat (or alternative grains), yeast, and other ingredients, bread stays fresh for only a short period before it starts to go bad.It may even grow mold and become unsafe to eat, so it’s helpful to know how to keep it fresh for as long as possible.This article explains how long bread typically lasts, how to tell whether it’s safe to eat, and how to increase its shelf life.
Many factors influence bread’s shelf life, which is the length of time it lasts before starting to go bad.The shelf life of bread kept at room temperature ranges from 3–7 days but may vary depending on ingredients, type of bread, and storage method.
Sandwich, loaf, or bakery breads available at the store often contain preservatives to prevent mold and increase shelf life. Without preservatives, bread lasts 3–4 days at room temperature.
Some common bread preservatives include calcium propionate, sodium benzoate, potassium sorbate, and sorbic acid. Lactic acid bacteria is an alternative that naturally produces anti-mold acids.
Gluten-free bread is more susceptible to mold due to its higher moisture content and limited use of preservatives. This is why it’s usually sold frozen instead of room temperature.
On the other hand, dried bread products, such as breadcrumbs or crackers, usually stay safe the longest because mold needs moisture to grow.
Refrigerated dough for biscuits and rolls also eventually spoils because it contains oils that go rancid.
Notably, most homemade breads don’t contain preservatives and may use perishable ingredients like eggs and milk. Some bakeries likewise avoid preservatives — you can check the ingredient list or ask the baker if you’re unsure.
