The dangers of eating expired soy milk may not be as severe as those linked with meat, but expired soy milk is risky that you should be well aware of. Just like with dairy-based milk products, soy milk has a short refrigerator life once opened. You can only keep it for 7-10 days after opening.
The cartons will start to bloat once they expire due to the gas produced by bacteria and mold feeding on the milk, causing color changes. The signs that soy milk is expired are similar to dairy milk. The consumption of soy milk will lead to reactions comparable to those linked with consuming expired milk.
Drinking expired soy milk can lead to symptoms of food poisoning, such as diarrhea, stomach upset, nausea, and vomiting. The global trade and production of soy doesn’t just impact biodiversity, it also affects Earth’s climate, generating significant amounts of greenhouse gasses. Proper handling and utilization of soy milk is a prerequisite. For more information on how to use expired soy milk, read this article.
Understanding Soy Milk Expiration
Causes of soy milk expiration
Unopened soy milk left out overnight may be at risk of going sour. Soy milk can be stored at room temperature, but failure to refrigerate once opened leads to early expiry. Soy milk in the refrigerated section must be cool, so it does not go bad. Opened soy milk, left out overnight, must be thrown away if it is not shelf stable.
Signs of spoilage and safety concerns
Soy milk has a short fridge life of seven to 10 days after opening. The first sign of bad soy milk is bloating of the carton from bacteria releasing gas. Another way to tell if it has expired is by checking the expiration date.
When expired, it may turn a rotten color and yield a curdled texture. If soy milk looks different from its usual off-white color and runny texture, that is a sign of expiration. Another way to tell if your soy milk is expired is by smelling it. Sour milk will have a rancid odor due to mold and bacteria. Unopened soy milk left out overnight is likely to yield a sour smell if it is the refrigerated kind.
Extending the Shelf Life of Soy Milk
Proper storage techniques
Store soy milk at room temperature
That is a tricky way to store fresh soy milk at room temperature. You must leave the product unopened so harmful bacteria do not grow. Soy milk shelf life is the longest at room temperature. However, opened soy milk cannot stay fresh at room temperature, since the oxygen in the air causes mold growth and other harmful microorganisms to accumulate. Keep shelf-stable soy milk in a pantry, where it is cool, dark, and away from direct sunlight.
Keep it in the refrigerator
Store soy milk in the fridge to keep taste and consistency. The refrigeration process slows the rate at which bacteria grow because of the cool temperatures. Open soy milk lasts between seven and ten days in the refrigerator. Locate the expiry date on the carton. Keep open soy milk in the fridge for a maximum of ten days.
Refrigeration and freezing methods
You can freeze soy milk to extend its shelf life. Although freezing can cause separation and texture changes, freeze soy milk by transferring it to an airtight container and leaving some space for expansion. Thaw it in the fridge overnight and shake well before using.
Pour your soy milk into the ice cube trays and leave it in the freezer overnight. Transfer the cubes into a freezer bag the next day for easier storage, or leave them in the tray.
Identifying freshness through sensory evaluation
Soy milk makes products like yogurts using a mixed starter culture containing Lactobacillus bulgaricus and Streptococcus thermophilus. Soy milk at 9 degrees Brix is homogenized under pressure (17 MPa) and fermented. Yogurt with the best sensory quality is obtained using homogenized soy milk with 2% sucrose addition and fermented for 6 h.
Creative Uses for Expired Soy Milk
Baking and cooking recipes
1. Expired soy milk pancakes
Flavorful substitutions include soy milk, almond milk, oat milk, or cashew milk for best results. Soy milk contains more protein than all the alternate milk. That is a requirement for baking projects that need a lot of structure. The high-protein content causes baked goods made with soy milk to brown.
2. Soy milk-based sauces and dressings
Classic ranch dressing uses buttermilk, mayonnaise, garlic, onion, spices, and fresh herbs. Replace buttermilk with unsweetened soymilk and lemon juice. The acid from the lemon juice complements the protein in the soymilk. Like dairy milk, soymilk is high in protein, ideal for vegan buttermilk. Soy Milk has no sugar, so add a touch for authentic flavor.
Homemade skincare and beauty products
1. Soy milk face masks
Soy milk contains soy isoflavone (Mayoclinic.org). It is for women added with yogurt and honey. The face mask is well known for improving skin luster and making it moist and supple. It is rich in nutrients that make your skin moist.
2. Exfoliating scrubs with soy milk
The exfoliator is there to renew and refine the skin. Apply scrub to the body and gently exfoliate, paying particular attention to dry and rough areas. It is ideal for dry, blotchy, or irritated skin, due to its nourishing moisturizers and gentle botanical extracts.
DIY household cleaning solutions
1. Soy milk-based furniture polish
Soy milk makes a soy paste that conditions your cutting board, polish turned bowls, or seals your favorite carved spoon. It is odor free, simple, inexpensive, and effective. It will make your furniture look incredible.
2. Natural soy milk detergent
Soy milk detergent is a rich blend of dried milk proteins and gentle ingredients. Combine with Vegetable Glycerin, Coconut Oil, Sodium Stearate, Sodium Myristate, and Olive Oil.
Transforming Expired Soy Milk into Animal Feed
Nutritional benefits for animals
Soy milk is full of protein since it is from soybeans. Soy milk increases your dog’s protein intake, promoting healthy tissue growth and repair. It is also low in fat and high in fiber. Unlike regular milk, soy milk contains less saturated fat. It is also a stellar source of calcium.
Guidelines for safely incorporating into animal diets
- Always follow the principles of variety and moderation.
- Blend soaked soybeans with water and strain the solids.
Examples of suitable animal species
- Dogs
- Pigs
- Chickens
Disposing of Expired Soy Milk Properly
Understanding environmental impact
Soy milk is one of the safest alternatives due to the lack of a high carbon footprint. However, production can lead to the emission of GHG that contributes to global warming, especially if farmers grow it on a large scale and feed animals that provide meat.
Pouring down the drain vs. alternative methods
Do not pour soy milk down the drain since that has an environmental impact. The process of breaking down milk uses a certain amount of oxygen, and by the time the process is completed, less oxygen is for the animals that rely on it. Milk in large quantities can suffocate entire ecosystems hence the devastating impact.
Recycling or composting options
Put the dairy products on top of a nest of dry brown materials and compost, as a filter to break down any leachate from the dairy products. Bury the dairy under a thick layer of already decomposing compost and dry materials, to help filter the smells that could attract pests.
Summary
Expired soy milk can cause food poisoning, but you can still use it for cooking, baking, or feeding animals. To keep it safe, refrigerate or freeze it. You can store it in a cool, dry, dark place, but only if it has not been opened. Reduce the amount of waste by adding the soymilk to a rotting layer in your garden.
