How can you tell if beef is bad and how can you tell if beef is bad?

How to cut off whether the beef is bad or not:

1. The color becomes darker.

The surface of fresh beef is shiny, and the color is uniform red or light red, if the surface of the beef turns gray or gray-green, or even white or black spots, it means that such meat has been spoiled and cannot be eaten.

2. The surface is sticky.

Fresh beef is slightly dry or moist on the outside, slightly moist on the cut surface, oily to the touch but not sticky, if the surface of the meat is sticky, or even drawn, it means that the beef has deteriorated and cannot be eaten.

3. Poor elasticity.

Fresh beef is tight and elastic, and when you press the fingers on the surface, it will recover immediately, and the longer it is stored, the less elastic the beef will become, and not only will it not be completely restored, but there will even be traces.

4. Odor.

The smell of fresh beef is generally a faint smell of meat, while spoiled meat will have a distinct sour and rancid smell.

5. Look at the moisture.

Look at whether the beef has moisture, if the beef is not water, it should be put for a long time, and some people will deliberately sprinkle a little water, which should be identified, to see if there is moisture in the middle of the meat.

Look at the gloss. Beef is something we often eat, and the taste and texture are the best choice, but beef is much more expensive than ordinary chicken, duck, fish, and pork. It is precisely because of this that you should judge carefully when buying beef.

The first step in choosing beef is to look at the color, the color of fresh beef is uniform red, white or creamy yellow fat. The color of the sub-fresh beef is dark red, and the fat covered in the beef is generally dull. Spoiled beef is brown or blackened in color, without light color, and the fat is green.

Smell the smell. When buying pork, we know that the freshness of pork can be identified by smell, and in the same way, beef can also be judged by smell to determine whether beef has gone bad. Fresh beef has the normal taste of fresh beef; Sub-fresh beef with a hint of ammonia or sourness; Spoiled beef has a rancid smell.

Look at the lines. Beef is generally cut horizontally, so the lines of real beef are more obvious, and the fake ones are more scattered. If it is boiled or frozen beef, we can also judge the quality of the beef, tear the meat, if the texture is clear, it is real beef, but if it is very broken, like meatballs, without texture, there is no doubt that it is not good quality beef.

Feel the elasticity. Everyone knows that beef is more expensive than pork, and pork can be eaten every day, every meal, but not beef, so it is not easy for us to buy fresh beef when we buy beef. In fact, the method of judging fresh beef is very simple, and fresh beef can quickly return to its original shape after being pressed by hand.

It takes a long time for the second fresh beef to return to its original state after hand pressing, and it cannot be fully recovered. Spoiled beef does not return to its original shape after being pressed by hand.

1. Look at the color, it is better to be bright red, and the texture is clear and better. Smell, smell the taste, the smell is more pure. Touch, the meat quality is elastic is preferred.

2. If you can't eat the fresh beef you just bought back on the same day and want to eat it the next day, you can wrap it in a thin cloth soaked in vinegar, which can ensure that it will not deteriorate for a day and night.

3. Put the mustard and fresh beef in a container, and then put the beef in a closed container (such as a pressure cooker, a crisper with a lid, a thermos flask, etc.), which can save the meat all day long.

4. Cut the fresh beef into pieces and divide it into the amount you eat each time, pack it in a plastic bag and seal it, put it in the freezer compartment of the refrigerator, and it can be stored for at least three months.

The ways to see if the beef is bad are: see if the color becomes darker; See if the surface is sticky; to see if the elasticity deteriorates; Smell if there is a bad smell, etc.

1. Darker color: The surface of fresh meat is shiny and the color is uniform. Fresh beef is red or light red, and the fat is white; As the storage time is extended, the flesh color will gradually turn reddish-brown.

The darker the color, the less edible it is. And when the surface of the meat turns gray or gray-green, or even white or black spots appear, such meat cannot be eaten.

2. The surface is sticky: the appearance of fresh meat is slightly dry or moist, the cut surface is slightly moist, and it has an oily texture when touched by hand, but it is not sticky; After the meat deteriorates, the surface of the eggplant meat is sticky, and even the sedan chair is being drawn. Sticky meat is a sign of the beginning of spoilage.

3. Poor elasticity: The texture of fresh meat is tight and elastic, and it will recover immediately after pressing the depression with your fingers. The longer it is stored, the worse the elasticity becomes, and the depression after finger pressure not only cannot be completely restored, but even leaves traces.

4. Peculiar smell: Fresh meat has a normal meat taste, while spoiled meat has a distinct rancid smell.
