Does Dry Pancake Batter Mix Go Bad?

by Fred Decker

The very best pancakes of all are homemade from scratch, but not every cook is alert enough or organized enough to prepare them first thing in the morning. For those occasions, prepared pancake mixes are a more convenient and reliable option. The shelf life of a pancake mix is very good, but it isn't unlimited. Over time, some problems can occur.

Pancake Mix Basics

Pancake mixes combine all the ingredients you'd need to make pancakes in a convenient dry form. The simplest varieties call for milk and eggs, while others are "complete" and only need to be mixed with water. They combine flour and a leavening ingredient, such as baking powder, and many include vegetable oil, dairy solids or dehydrated egg. As a rule, mixes will keep for at least a year in your pantry, unless you live in an especially hot or humid climate. Eventually, its quality and flavor will begin to suffer, although the mix usually remains safe to eat.

Rising to the Occasion

One of the most common problems that occurs as your pancake mix ages is a loss of rising power. The baking powder that makes your pancakes light and fluffy contains both an acidic and an alkaline ingredient, which remain inert when they're dry but react with each other when they're moistened. Moisture in the atmosphere can cause a slow-motion version of that reaction, gradually using up your leavening. The pancakes won't have any off flavors, but they'll be flat and leathery rather than light and fluffy. Compensate for that by adding fresh baking powder from your cupboard, then replacing the pancake mix at your next opportunity.

The Nose Test

Many pancake mixes contain fats, either in the form of vegetable oil or dried egg. The oil is usually hydrogenated to extend its shelf life, and most brands include preservatives and antioxidants as well. Those prevent the fats from reacting with oxygen in the atmosphere, which eventually breaks down the fat molecules and produces rancid flavors. Rancidity gives your pancakes an unpleasant flavor and odor, which is easily detected once you've added liquid to the dry mix and started cooking. Discard any mix that smells rancid.

The Taste Test

As your pancake mix reaches and passes its freshness date, it will gradually begin to lose flavor. Over time, it might come to taste more like its box than a well-made pancake. That stale flavor is a sign of age and oxidation. It's not dangerous, but it does mean that your pancakes aren't pleasant to eat. To minimize staleness and extend the shelf life of pancake mix, keep it in its original packaging -- often impregnated with preservatives -- or in an airtight, food-grade container.

A Few Rare Cases

Although poor rise or flavor are the most typical issues after a stretch of time in the pantry, there are a few others. For obvious reasons, discard any mix with signs of insect or rodent pests. Also, throw it out if it shows signs of contamination by any liquid. If you're allergic to molds, avoid any mix that hasn't been tightly sealed. In rare instances, mold spores can find their way into the mix and trigger an unpleasant or even life-threatening allergic reaction.
