The last couple of years have seen soy protein demand increase significantly. The legume is a nutrient-dense, with numerous vitamins, minerals, isoflavones, and fatty acids essential for optimal body functioning and general well-being. Also, it has health and therapeutic benefits and can reduce cholesterol levels, support muscle health, improve cardiovascular health, and ease menopausal symptoms.
Soy protein is an excellent choice for vegans and people looking to add more plant-based proteins to their diets. Also, it is handy for people who can’t consume dairy for health and ethical reasons or want to try something fancy but nutritious. Like most foods, soy protein must be stored appropriately to preserve nutrients and maximize freshness.
Read on to learn how to store soy protein.
Types of Soy Protein and How to Store Them
Soy protein is harvested from soybeans in different ways to make soy protein concentrate, soy protein isolate, and textured soy protein, with varying storage requirements. However, most Soy protein should be stored in an excellent, dry space in a pantry, drawer, wall shelf away from direct sunlight, or closet.
The emphasis is to keep the soy protein cool, not cold or hot. Do not store the soy protein in a freezer because it may cause condensation, increasing the likelihood of spoiling before the expiration date. Similarly, storing soy protein in a warm space of more than 70oF lowers its shelf life.
Most brands design soy protein packaging to foster proper storage. The protein comes in a well-sealed tub, zip-lock bag, or pouch. Consequently, you can store the protein in a dry and dark place in its original packaging without transferring it to a tub or pouch. Nonetheless, ensure you twist the lid tightly or reseal the pouch after every use.
Keep your packaging away from sunlight and water, the biggest enemies to shelf life. It is best practice to store soy protein front and center in your pantry or cabinet so you remember to use it. You don’t want to discover your soy protein past the expiration day when cleaning your pantry.
Many people ask how long soy protein lasts. Typically, the shelf life depends on storage conditions, manufacturing date, and the presence of preservatives. You can expect an opened soy protein to last six months to one year while an unopened one can last up to two years. The presence of preservatives increases shelf life tremendously. Product labels provide valuable insights into how long to store your protein.
1. Soy Protein Concentrate
Soy protein concentrate is made by extracting carbs from defatted soybeans so they have high protein content. It has a creamy white or light-yellow color with a soybean smell. Depending on your preferences, you can buy soy protein concentrate as a fine powder or granules. This soy protein is mainly used in shakes, breakfast cereals, meat substitutes, bread, soups, and sauces.
When it comes to storage, keep the concentrate in a ventilated pantry or cabinet at 25oc max and low humidity. The concentrate can last between 12 and 24 months. Although soy protein concentrate does not have dairy, it is vulnerable to mold when stored in a high-humidity space. Watch out for spoilage signs like discoloration, foul smell, clumpy appearance, and rancid taste.
2. Soy Protein Isolate
It has the highest protein content and is made when fats and carbs are removed from soybeans. While soy protein isolate is nutritionally dense, it does not have all the health benefits of soy protein because some isoflavones are eliminated in the production process. This soy protein makes protein powders, supplements, and bars.
Also, it increases protein content, moisture retention, and texture in meals. The best place to store soy protein isolate is a cool, dry place in a sealed container. When exposed to moisture, bacteria grow in the soy protein. Similarly, heat and light degrade the isolate with time. Typically, soy protein isolate can last up to 18 months.

3. Textured Soy Protein (TSP)
It comes from processed soy flour made into distinct shapes and forms like flakes, chunks, and granules. Soy enthusiasts use TSP to prepare famous soy-based dishes like chunks and curries. TSP is a solid and nutritious substitute for ground beef.
The storage instructions for TSP vary from one product to another. Fortunately, most brands provide use and storage instructions on the package. Most textured soy proteins have a one-year shelf life in correct conditions. When rehydrated, TSP should be used immediately or stored in the fridge for three days.
Conclusion
Soy protein is a good plant-based protein with a rich nutritional profile and many health benefits. Like most foods, soy protein, whether concentrate, isolated, or textured, should be stored in ideal conditions to maintain freshness, quality, and flavor. When you buy soy protein, read its label for storage guidelines and expiration date. Do not forget to keep the lid tightly closed to prevent light and humidity from wreaking havoc.
