Baking Soda: The Smart Prepper’s Secret Problem Solver

There are a few staple items that are nearly impossible to produce at home. Baking soda is one of those basic commodities that every smart prepper should keep in stock.

Why should every prepper stock a large supply of baking soda? Baking soda can be used in recipes as a leavening agent, in cleaning products, as a deodorizer, for personal hygiene, medicinally, and the list goes on. Baking soda has very few good substitutes and is not a product that can be made at home.

Now let’s explore what every prepper needs to know about storing and using baking soda.

What is Baking Soda?

Baking soda is a crystalline white salt that is sold in a powder form. It is an alkaline compound that is also known as bicarbonate of soda or sodium bicarbonate. Baking soda reacts with heat or when combined with acidic substances and releases carbon dioxide.

Soda ash, as baking soda was originally known, was developed in 1791 in France. It was first manufactured in the United States in 1846. Although it is relatively new on the scene, it has become an inexpensive, yet valuable, resource.

It is important to note that baking soda and baking powder are different and cannot be used interchangeably.

Baking powder is usually a combination of sodium bicarbonate, calcium acid phosphate, sodium aluminum phosphate or cream of tartar. Both baking soda and baking powder are used in baking. Baking soda is used in recipes that have acidic ingredients while baking powder is used in recipes without acidic ingredients.

Baking soda has mild disinfectant properties and is an effective fungicide.

Shelf-Life of Baking Soda

Storage conditions play a significant role in the actual shelf life of baking soda. According to Arm & Hammer, the official shelf life of baking soda is 3 years. An expiration date is located on the bottom of the container.

In practice, I have found that baking soda is stable and has an indefinite shelf life. It does not usually “go bad” but it is possible for baking soda to gradually lose potency over time.

A quick test to check the potency of your stored baking soda only takes a minute. Either of these methods will work:

  • Mix a cup of hot water with a teaspoon of vinegar. Add a spoonful of baking soda.
  • Place a tablespoon of vinegar or lemon juice in a dish and add ¼ teaspoon of baking soda.

With either method, if the baking soda is still viable, it will immediately start to fizz and produce healthy bubbles. As it loses potency over time, those bubbles will become less vigorous.

Ideal Storage Conditions for Baking Soda

Baking soda will store indefinitely in an air-tight, moisture-proof container in a cool (40°-70°), dry location. Baking soda loves to absorb moisture and odors which make the storage container critical.

Baking soda can be purchased in a variety of containers, and the type of container it is stored in will impact the actual shelf life of the product.

Cardboard Box

Baking soda stored in cardboard boxes are prone to attract moisture and will only last for a short period of time due to the packaging. To extend the life of these boxes, place them in a sealed plastic bucket to add an additional protective layer against moisture and other environmental factors.

Plastic Pouch

Baking soda stored in original plastic pouches provides an adequate moisture barrier. Short term storage of 1-3 years is fine in this original packaging.

If you plan on storing baking soda in plastic pouches for a long time, it is a good idea to place the plastic pouches inside of a sealed plastic bucket. This adds an additional layer of protection and will help protect the baking soda.

Plastic Bucket

Baking soda originally packaged in a sealed plastic bucket is a good candidate for longer-term food storage. A 1-gallon bucket holds 10 pounds of baking soda. A 5-gallon bucket holds 50 pounds of baking soda.

I prefer to store several 1-gallon buckets instead of the larger bucket. Once a bucket is opened the shelf life is reduced and contamination is possible. I like the convenience of the smaller gallon buckets. You can purchase them here.

Metal #10 Can

Baking soda properly sealed in a #10 can is great in a long term survival food supply. It provides a true oxygen and moisture barrier. A #10 can contains roughly 7.25 pounds of baking soda.

How Much Baking Soda Should I Store?

It is impossible to accurately estimate exactly what your need will be because we don’t know the challenges that you may have to face. I always like to err on the side of too much rather than too little when it comes to staple supplies.

When you are living a basic survival lifestyle where you cook from scratch and make your own cleaning supplies you will find that you use much more baking soda that you do in normal life. Plan ahead and don’t skimp on this inexpensive resource.

We prepared this table to help you think through what your survival baking soda needs may be.

Baking Soda Needs for Survival Food Storage Person/Year
Food Preparation and Cooking
(if baking powder is stored in addition to baking soda)
1 pound
Food Preparation and Cooking
(if no other leavening agent is stored)
3 pounds
Personal Hygiene2 pounds
Medicine and First Aid1 pound
Cleaning and Deodorizing (per household)5 pounds
Miscellaneous Needs1 pound

A one year supply of baking soda for 1 person to use exclusively in baking is approximately 1 pound as long as you are also storing 4 pounds of baking powder per person. If you are solely using baking soda for cooking, a safer estimate is 3 pounds of baking soda per person.

If you plan to use baking soda for baking, cleaning, personal hygiene, medicine, first aid, and other uses, I would recommend storing 10 pounds per person per year.

I look at it this way. Baking soda is inexpensive and is a critical resource. If you store more than you need, baking soda will be a great barter item.

Best Variety of Baking Soda to Store

Make certain that you store pure baking soda without additives. There are very few good substitutes for baking soda.

Prepper Uses for Baking Soda

There are hundreds of uses for baking soda that could be helpful to preppers as they strive to be self-reliant and make the best with the resources that they have. We share only a few that we have found useful in our preparations.

Food Preparation and Cooking

Baking soda is an irreplaceable ingredient when it comes to turning basic stored foods delicious meals.

Soften Older Beans

Simply add 1 teaspoon of baking soda to the water when you soak older beans to shorten cooking time, reduce gas, and improve digestion.

Create Incredibly Fluffy Omelets

Create fluffier eggs by just adding ½ teaspoon of baking soda to 3 eggs and whip before turning into them into tasty omelets or scrambled eggs.

Caramelized Onions Quickly

Caramelized onions can be created in a matter of a few minutes if you add ¼ teaspoon of baking soda per pound of sliced onion before sauteeing.

Transform Spaghetti into Ramen

Change spaghetti noodles to Ramen textured noodles by adding 1 teaspoon of baking soda to the water before boiling spaghetti noodles.

Tenderize Meats

Tenderize tough cuts of meat by soaking the meat in a solution of 1 teaspoon baking soda in ½ cup water for 15 minutes.

Crispier Fried Foods

Breading fried foods in a batter that includes baking soda and an acid ingredient (think buttermilk, lemon juice, vinegar) will create a crispier fried product. It also helps bond the batter to the food a little bit better.

Baking Soda as a Leavening Agent in Baking

Baking soda is used as a quick-acting leavening agent in baking. It helps food to rise as it releases carbon dioxide bubbles. Mixing baking soda with acidic foods such as buttermilk, brown sugar, vinegar or lemon juice increases the release of carbon dioxide.

Baking Soda Substitutes in Baking

There is no real effective substitute for baking soda. It is a basic staple item in your long term survival food storage. The best idea is to make sure that you store plenty in your food stores.

Baking powder can be substituted in some recipes for baking soda at a ratio of about 1 teaspoon baking soda to 3 teaspoons baking powder. It is important to reduce the amount of salt in the recipe. Also, replace acidic liquids (vinegar, lemon juice, buttermilk, etc.) in the recipe with non-acidic liquids (milk, water).

1/4 – 1/3 teaspoon baking soda = 1 teaspoon baking powder
1/2 teaspoon baking soda = 1/4 teaspoon potassium bicarbonate (low sodium substitute)
1 teaspoon baking soda = 3/4 teaspoon ammonium bicarbonate
