Can you taste expired food before throwing it away?

I believe you must have faced it.

The question of whether to eat expired food or not

So today I will give you an answer

Before that

Everyone should first understand

Everyone should know

This "period" is the shelf life of food

But

The shelf life does not mean

After this time

Food will spoil immediately

Shelf life refers to the period during which quality is maintained

In this time

Food can be sold

And if within the shelf life

You've got a stomachache from eating this.

You can ask for compensation from the food factory.

But if you eat expired food

I've eaten my stomach.

Food factories don’t have to take responsibility

So the shelf life

In fact, it is the food factory and the customer

You, the eater.

A contract between you

After the expiration date

You have no contractual relationship with the manufacturer.

If you get sick from eating again

It's your own problem too.

Although I have foreseen the future of Da Mao

But this question

It's quite curious.

The shelf life is quite strict.

It's not what you want to decide.

Before setting a shelf life

It is necessary to conduct various microbiological tests on food

Determined under certain conditions

Changes in the content of two pathogens in food

Generally speaking

Before these two bacteria exceed the standard

All belong to edible time

It is during this time period

Theoretically, you won't die if you eat it.

But for greater safety

When setting the shelf life

The merchant will be based on the edible time

Compress the time to be shorter

After all, if you eat it within the shelf life and get diarrhea

It's the food factory's responsibility

How much shorter?

General merchants

Refer to the time when food starts to taste bad

For example, starting from the 20th day

This thing is starting to taste bad.

According to the above formula

The shelf life of this food is

20×0.7/0.8=14/16

The shelf life is about 14 to 16 days.

So in many cases

Expired food just doesn’t taste good anymore

Maybe you can eat it in a short time.

Although the shelf life is not the last edible period

But not everything

There is always a glimmer of hope that you can eat it after it expires.

That's right

High-protein foods like eggs

If it expires

It's best not to eat it anymore

Everyone knows eggs.

It is easy to get stained with feces when it is born.

It's not a big deal if you get stained with poop

But if the mother hen is unlucky

Salmonella on the body

The eggs are likely

Contaminated by salmonella in stool

Salmonella in eggs

Can reproduce in large numbers

At room temperature

Eggs laid for more than 21 days

Bacteria will exceed the limit

The shelf life of eggs is only 3-5 weeks.

Although it may not look bad

But in fact, there may already be a lot of bacteria in the eggs.

Even if the eggs are already cooked

But the place where the eggs were touched

Salmonella may remain

For example, your hands

Meat itself contains a lot of bacteria

Under suitable conditions

Bacteria can easily multiply and cause corruption

Fresh meat refrigeration time

It is best not to exceed two days

Like the usual meat snacks

Although it has undergone some anti-corrosion treatment

But it's still possible that it will deteriorate.

So no matter how delicious the meat products are

Don't eat it once it's expired.

but

I guess no one really eats expired meat.

That's right

Cooking oil also expires

Although the shelf life of oil is generally 18 months

But if it is edible oil after opening

Best used within 3 months

Because the oil is in contact with air for a long time

Oils and fats are affected by oxygen, water, light, and microorganisms

Hydrolysis or oxidation reaction may occur

In addition to producing peroxide

May have adverse effects on the human body

During the heating process after the oil becomes rancid

The smoke generated

It also contains the decomposition product epoxy propionaldehyde

After inhalation and consumption

It may also cause poisoning

Good in the tender care of mother

I finally finished

To sum up

Expired eggs, meat and cooking oil

Absolutely not to eat

But in the case of better storage

Some expired foods in the short term

There's still a chance I could try it.

Don't learn from Da Mao.

Can be eaten within the shelf life

Try to eat it within the shelf life.

We don't need a day or two.

Right
