Spoiled milk can replace buttermilk or sour cream in baked goods. It can also be used to tenderize meats or added to soups, casseroles, or salad dressings. You can likewise use it in certain cosmetic applications to soften your skin.
1 Sour milk is made.
This can be lemon juice, vinegar, a beneficial bacteria, or even another sour milk product. This is how homemade buttermilk and homemade sour cream substitutes are made. However, spoiled milk is usually milk that was left out for too long or was opened and then stored incorrectly.
But spoiled milk is a different story...
Besides the unpleasant taste and smell, spoiled milk can cause nausea, stomach cramps, or diarrhea. If you use spoiled milk for baking, the oven heat destroys most of the harmful bacteria so there is less of a chance that you will get sick from it.
Diluted expired milk is great for watering your plants! Calcium is a nutrient essential to plant health. Specifically, calcium is responsible for supporting cell walls. If your plant is calcium-deficient, root tips, young leaves, and shoot tips could have trouble growing.
While it's always important to inspect your milk before drinking it, most milks are safe to drink several days after the printed date on the label. That said, the flavor may start to decline. To avoid food waste, older milk can be put to use in pancakes, baked goods, or soups.
Fry it. Expired milk is a great adhesive for a thick layer of breadcrumbs, and breadcrumbs turn any less-than-glorious produce into tasty snacks. Squash, eggplant, and green tomatoes are all great.
As strange as it sounds, you can actually water plants with milk. Even if you can't drink it yourself, it makes for a stellar fertilizer. According to Gardening Know How, expired milk is loaded with calcium, protein, vitamins, and sugars that can help give your plants an added boost and help them grow big and strong.
Any type of milk, including fresh, expired, evaporated, and powdered, can be used in a garden as long as it's diluted properly. Stick with reduced-fat (2 percent) or low-fat (1 percent) milk, rather than skim or whole options.
It contains beneficial proteins, vitamin B, and sugars that are good for plants, improving their overall health and crop yields. The microbes that feed on the fertilizer components of milk are also beneficial to the soil. Like us, plants use calcium for growth.
As milk is a good source of calcium, you can use it to feed your plants occasionally. This milk fertilizer can be used for many vegetable plants, more specifically for the likes of tomatoes, peppers, and squash that suffer from blossom end rot. Milk is also wonderful for citrus plants like lemons and oranges.
But as long as milk has been properly refrigerated, it should be still drinkable up to a week past the date label — and maybe up to two weeks, depending on the temperature of your refrigerator. Generally, as long as the milk smells and looks OK, it's probably still safe to consume.
A small sip of spoiled milk is unlikely to cause symptoms beyond a bad taste. Drinking larger amounts of spoiled milk can cause stomach distress resulting in abdominal cramping, vomiting and diarrhea (like a food-borne illness). In most cases, symptoms caused by drinking spoiled milk resolve within 12-24 hours.
Sour milk has an unpleasant smell, but baking soda is a convenient odor-absorbing tool to always have on hand. Generously sprinkle baking soda onto the affected area, whether it is wet or dry, and leave it overnight.
Make Butter
When milk is beginning to sour, skim off the cream and use it for making butter. The cream will sour slower than the milk because it contains more sugar. Pro Tip: Use the cream to make butter and then throw the butter into the freezer for recipes that require melted butter.
If you've ever left milk in your fridge for long enough to curdle, you've made a rudimentary (and not very tasty) form of cheese. Cheese is the human-administered spoilage of milk, resulting in a less perishable, more delicious form of concentrated fat and protein.
While the heat of baking destroys many of those bugs, experts say it's probably not worth the risk. And excessively spoiled milk may give an off flavor to your baked goods. Instead, use buttermilk, or stir vinegar or lemon juice into fresh milk (1 tablespoon per cup) to simulate the curdling and acidity.
The spoilage bacteria in raw milk are mostly aerobic Gram-negative psychro trophic rods, such as Alcaligenes, Flavobacterium, Pseudomonas, and some coliforms. About 65–70% of psychrotrophic microorganisms in raw milk is Pseudomonas spp.
However, research has shown that pouring milk down your drain is terrible for the environment. It takes a lot of oxygen to break down milk, taking oxygen away from living organisms that need it to survive. Large amounts of milk have even been known to suffocate entire ecosystems.
Milk and other dairy products are considered “solid waste” under the state solid waste regulations. As such, land disposal of these products is prohibited except at a site that has received a “certificate of designation” as a solid waste disposal facility from the applicable local government.
It is against federal and most state environmental regulations including Texas, to dump milk into surface water or on any non-permeable surfaces.
If milk is left out of the fridge for an extended period of time it can become a food-safety issue. Bacteria start to grow and replicate when the temperature of your milk reaches 40°F, and those bacteria are how you end up with a gallon of nasty, rotten milk or, at worst, contract an illness.
If no fertilizer or manure has been applied, milk can be used to supply the primary nitrogen requirement of the crop as a pre-plant fertilizer.
Coca-Cola does not cause for plants to grow taller and grow more leaves. In the end Coca-Cola is very bad for plants and causes for them to dry up faster, die quicker, grow smaller and not to grow as many leaves.
Houseplants, just like humans, need calcium and other nutrients in their diet to stay strong and healthy. Milk contains proteins, sugars, and nutrients we need to power our bodies for our day-to-day, and adding several drops to your houseplants in the right way can be beneficial for their wellbeing as well.
