In daily life, when processing food, you will have difficulties in identifying spoiled food. That sometimes affects the quality of the food. It is often very apparent when certain foods have expired, but it can be a bit more difficult to discern with other foods. Generally speaking, any food that has a foul smell or has changed texture is spoiled and should not be used. Here are some tips to identify spoiled food:
To identify whether eggs are fresh or not, you should beat eggs into a bowl of cold water, if the eggs sink to the bottom, they are very fresh eggs. In the case of floating eggs partly meaning that the old eggs are still edible. If the eggs are floating on the surface of the water, they are too old. they should be discarded.
Most butter can be used for a long time, rarely overdue. But if that happens, be aware of their discoloration, sourness, and smell. Usually, butter can be stored for 4 months in the refrigerator. If it is stored outside, you need to shield the butter from sunlight.
For bread, any sign of mold must be removed. Spicy bread helps the roots of mushrooms spread quickly to all corners of the cake. The tops can be changed to many colors from green to white.
Canned food cannot be left for too long. In addition to viewing the expiry date, you should also pay attention to the condition of the box. If the shell is dented, rusty, or the lid is bulging, this is a sign that the food inside is not intact. The most dangerous is when the lid is bulging. This is a sign of fatal botulinum bacteria inside. It accumulates and releases gases that create pressure on the box. To identify spoiled food, you should care for them!
Signs of broken milk are when there is a strange odor, milk changes color or when the surface is sticky. The same is true for other dairy products. Ice cream will also have these signs, even mold.
Checking the freshness of fruits is quite easy. You can identify by changing texture and color. Mold, staining, wrinkled crust, or stinking are signs that fruit is no longer edible. Banana is a special fruit. When the shell turns black and the texture changes, bananas are too ripe, not broken. If you don’t like to eat, you can use ripe bananas to make baked goods, such as baked banana bread.
It is difficult to identify spoiled poultry by color because some types of meat are white to yellow, red or pink. The only color you should not eat is dark gray. Another reliable sign to identify spoiled poultry is a burning smell, or a too slime texture.
You can keep old meats for 5 days after peeling. They contain a variety of preservatives and undergo elaborate processing. When the meat is spoiled, they become slimy and can smell like vinegar or ammonia.
All kinds of rice, if properly stored, have an almost endless shelf life. However, brown rice can spoiled quickly within 6 months due to the content of oil inside. Ripe rice is a completely different story. You do not try to keep rice after cooking for 4 to 6 days. When the rice appears fragrant or becomes too dry, you should remove them.
The freshness of green vegetables depends a lot on how you preserve them. Most vegetables will drop in quality when there are signs of discoloration, softness or pasty, wilting or mold. Some types such as potatoes and onions, if kept long, tend to sprout. You can remove the sprout to use, or if your stomach is weak, remove them.
Yogurt has live bacteria, which is good for intestinal health and acts as a preservative. But, after a while the bacteria will die, leading to mold, clots or too much water. If you find yogurt to have more water than usual, you should remove it and buy a new one.
The fish has a fishy smell. But, if the smell becomes strong, it is a sign that the fish has no longer been eaten. Similar to red meat or poultry meat, the texture of fish flesh when spoiled will be irregular and sticky. The general rule when processing fresh fish is that you should not leave fish for more than 36 hours.
Cheese is the most difficult type of food to judge because it tends to eat better over time. Remember that soft cheeses like feta, mozzarella, cream cheese will have a short shelf life due to high humidity. You can use hard cheeses like parmesan, cheddar much longer. Even if the cheese has mold on the outside, you just need to remove that part and use it normally.

For types such as clams, oysters, snails, mussels …, if they boil, they do not open their shells, they should be discarded immediately.
