Food additives are not allowed to be added to food, so how to ensure that food does not deteriorate?

Food spoilage is due to bacteria, but there are two large bacteria in the airIn order to slow down the spoilage time of the food without spoiling, the food can be isolated from the airIn the era when there was no refrigerator, in order to prolong the preservation time of food, people often steamed food at high temperature, and then sealed and stored.

High-temperature steaming can kill most of the bacteria and other organic matter in the food, so that the food loses the source of spoilage (spoilage). And then sealed, so that external bacteria can not enter, so as to achieve the purpose of long-term preservation of food without spoilage. Similar methods include pickling, drying, etc.

Pickling is also about creating an environment where bacteria can't multiply so that the food doesn't spoil. Pickling is to make the salt content of the food reach a very high concentration, so that the cells cannot take in nutrients and water and cannot survive, (this can refer to the principle of cell membrane osmosis). For example, salted fish, pickles.

Drying is mostly used in pasta, so that the food lacks the moisture needed for bacteria to multiply. Of course, this method is only suitable for areas with dry air.

There are also several specific preservation methods:

Fresh meat preservation method, with vinegar-soaked cloth, fresh pork wrapped in a refrigerator, can be stored for two days and two nights without spoiling. You can also pour the boiled and cooled peppercorn brine into the container, soak in the fresh meat (to submerge the food) and put it in the refrigerator, which will not deteriorate for two or three days. Tofu preservation method Soaking tofu in cold boiled water or salted boiled water can reduce the oxidation of microorganisms and will not become rancid after two or three days.

Fresh fish preservation method, buy live fish, you can pour a few drops of white wine into the fish's mouth, and then put it into a basin with water, which can prolong the life of the fish. In the egg preservation method, a layer of cooking oil is applied to the surface of the egg, which can prevent the invasion of bacteria and prolong the storage period of fresh eggs.

Spoilage due to microbial activity while preventing food.

The formation of harmful oil oxides prevents food from spoiling.

It is difficult to ensure that food does not deteriorate without adding food additives.

It is impossible to add food additives to food, and many things cannot be stored for a long time.

There is no way to guarantee this. The main thing is the role of preservatives.

If you don't add food additives, the shelf life is definitely shorter.

This is difficult to do, and the shelf life of each food will be greatly reduced.

Nowadays, most foods have preservatives added and may not be put in directly.

It is possible to create a low-oxygen environment so that food is less susceptible to spoilage.

Maybe they have other ways to do this, we don't know.

1.Antioxidants: can inhibit oxidation reactions and delay the oxidative deterioration of food, such as vitamin C, vitamin E, citric acid, etc.

2.Preservatives: can inhibit the growth of microorganisms and delay the spoilage of food, such as potassium sorbate, sodium benzoate, sodium formate, etc.

3.Pigments: can make food have a good color and increase the attractiveness of food, such as monascus pigment, carotene, caramel pigment, etc.

4.Spices: It can increase the flavor and texture of food, and make Dadai Xun food more delicious, such as vanillic acid, clove acid, rolling star anise, etc.

5.Starter culture: It can promote the fermentation process of food, increase the taste and nutritional value of food, such as schizomyces yeast, flour, baking powder, etc.

The role of food additives The rational use of food additives can prevent spoilage and deterioration of pure food products, maintain or enhance the nutrition of food, and improve or enrich the color, aroma and taste of food.

The necessity of using God to make food additives is actually. Not using preservatives is more dangerous because spoiled food tends to cause food poisoning illnesses. In addition, preservatives can not only prevent food deterioration, but also kill toxin-producing microorganisms such as aspergillin, which is undoubtedly beneficial to human health.

The safe dosage of food additives without any toxic effects or adverse effects on health is expressed as the mass (mg) per kilogram of daily intake, i.e. mg kg. China's relevant food hygiene regulations have strict restrictions on the dosage of food additives. The use of food additives in excess of dosage and scope will cause harm to the human body and belong to the abuse of food additives.

Non-edible substances are not food additives, and non-edible substances are not food additives. Adding non-edible substances to food is a criminal act that seriously threatens the food safety of the people, and it is also an illegal and criminal act that hinders the healthy development of China's food industry and undermines the order of the socialist market economy. Since the rectification of illegal addition of non-edible substances and abuse of food additives has been carried out, the Ministry of Health, together with relevant departments, has established a "blacklist" system for illegal additions, and has published five batches of a total of 47 illegally added non-edible substances, none of which are food additives.

See the table on the next page for a specific list. In the list, it is clear that "non-edible substances that may be illegally added in food" and "food additives that may be abused in food" are clearly distinguished, such as hanging white blocks, Sudan dyes, melamine, etc., which have caused serious food safety incidents, are actually illegal additives, not food additives.

Summary. Hello dear, of course, you can do without food additives.

Hello dear, of course, you can do without food additives.

Home-made baked goods that are not of high quality can be prepared without food additives.

Some food additives can also be harmful to health.

However, food additives play a huge role in food technology, which can not only preservative, preservation, improve the circulation range of food, prolong storage time, but also improve food taste, appearance and nutrition.

Are food additives in beverages harmful to humans.

This is generally not available, because the products that can be sold are strictly tested.

It can only be sold if it is harmless to the human body.

Food additives are not beyond the scope and amount in food, and they are harmless to the human body, and some are even beneficial to the human body.

Master Kong's jasmine tea is very delicious, but there are food additives in it, right, what's wrong? Long-term drinking?

Drinks are not suitable for long-term consumption.

Only in moderation.

Thanks! Sorry for your help!

Additives are available in all foods on the market nowadays.

It's just that this level is within the normal range.

As long as it doesn't exceed the standard, you can drink it with confidence.

You mean it doesn't matter?

Yes. You just can't drink it for a long time.

Food additives are not beyond the scope and amount in food, and they are harmless to the human body, and some are even beneficial to the human body.

Generally, food preservatives are not used, because nuts such as melon seeds and pistachios do not have high moisture content and are not easy to spoil.

However, nuts are generally processed by frying, and nuts themselves contain more oil, so they are prone to oxidation and even rancidity. Oxidation of oils and fats not only reduces the nutrients contained in oils, but also produces harmful substances that endanger human health. After the oxidation rancidity of oils and fats in food, whether it is its peroxidation product or its secondary product, it is a harmful substance to the human body.

Lipid peroxides produce free radicals in the body, which can cause damage to biofilms, proteins, DNA and other macromolecules. Therefore, roasted nuts are generally preserved by adding antioxidants. Such as tert-butylhydroquinone (TBHQ), butyl hydroxyanisole (BHA), dibutyl hydroxytoluene (BHT), propyl gallate (PG), ascorbyl palmitate and other monomers or compound antioxidants.

Food antioxidants are a class of food additives that can prevent or delay the oxidation of food, improve the stability of food and extend the shelf life. Food antioxidants can prevent or delay the failure or rancidity of food due to oxidation due to oxygen during processing or circulation, thereby preventing or delaying the rancidity or rancidity of food due to oxidation. Compared with preservatives, the safety of antioxidants is relatively high, and currently widely used is TBHQ or ascorbyl palmitate, and there are some natural antioxidants such as vitamin E, vitamin C, tea polyphenols, etc.

Among them, ascorbyl palmitate has been identified by the World Health Organization (WHO) Food Additives Committee (FIO) as a nutritious, non-toxic, high-efficiency, safe antioxidant, and is included as a pharmaceutical excipient by the United States Pharmacopoeia, not only an antioxidant but also a nutritional enhancer (vitamin C supplement).

In order to reduce the use of food additives and ensure a better anti-oxidation effect, many melon seeds are now packaged with a small package of oxygen absorbers. In addition, from the food additives column of the packaged melon seeds in the ingredient list, you can see what antioxidants are used in the product.

I'll get back to you right away.

The most common are sorbic acid and benzoic acid and their salts, and there are some natural biological preservatives such as lactic acid streptococcin, natamycin, etc., which also have good preservative effects. Comparatively speaking, preservatives are less harmful to the human body. Excessive use of sodium benzoate will cause peculiar smell, excessive intake will cause cramps and other poisoning phenomena, and will also lead to intestinal flora disorders.

You can refer to it.

Reduced iron powder is used in food additives in addition to preventing food from deteriorating due to oxidation, it is also a nutritional enhancer, because iron can react with water and oxygen in the air to prevent food from spoiling, and iron reacts with gastric pain (HCl) in gastric juice to produce ferrous ions and iron supplementation, which can prevent iron deficiency anemia.

1. Maintain or improve the nutritional value of the food itself, such as the nutritional enhancer in high-iron soy sauce.

2. As a necessary ingredient or ingredient in some special foods, such as potassium carbonate in infant formula.

3. Improve the quality and stability of food, such as antioxidants in edible oil.

4. Improve the sensory characteristics of food to make it taste better, such as emulsifiers in ice cream.

5. It is convenient for the production, processing, packaging, transportation or storage of food, such as preservatives in canned fruits.

In fact, for most processed foods, it is almost impossible to produce without the right amount of food additives. So, do food additives cause harm to the human body? According to the "Shenyang**" report, the state has strict regulations on the dosage, scope and method of use of various food additives, which are based on a set of scientific and rigorous toxicity evaluation, so as long as it is a food produced by regular manufacturers, even if it contains food additives, it will not harm human health.

In addition, many people are very concerned about the shelf life of food when buying food, and feel that food with a longer shelf life is not good for health. However, according to the "Health Times", the shelf life indicated on the food packaging is determined by the company according to many specific experiments, so for different types of food, the length of the shelf life will be very different, such as bread, vegetables, etc. The shelf life is generally short, while the shelf life of biscuits and drinking water is relatively long. And due to the differences in processing methods, even if it is the same food, its shelf life may be different, for example, the shelf life of some milk is as long as half a year, and the shelf life of some milk is only a few days, but as long as it is produced by regular manufacturers and tested by relevant testing institutions, it will not harm human health.

Therefore, when you buy food, it is best to go to some relatively large supermarkets to ensure that you can buy fresh and regular food.

Dear, hello, I am happy to answer for you, approaching the main content of the mistakes in food additives in science: Many edible items in daily life are not made of raw materials, but are made of some ordinary food additives according to the appropriate amount and ratio. Dietitian Wang Xufeng will unveil the secrets behind food safety, and he will be able to prepare a variety of beverages without fruit.

Not only beverages, but also jelly, meatballs and other edible products are formulated from food additives, and excessive intake of additives by the human body will pose a threat to health, especially in children, these additives should be avoided.

Summary. Yes, food additives refer to one or more substances used to change the physical, chemical and biological properties of food in the production, processing and storage of food to enhance the shelf life, color, aroma, taste, nutrition, quality stability and other characteristics of food. They can be natural or synthetic.

The use of food additives can help make food production and processing more convenient and efficient, while also protecting food quality and safety, and improving taste and appearance. However, excessive or unnecessary use of food additives may cause potential harm to human health. Therefore, many countries and regions are.

Are food additives substances added to food? Why?

Yes, food additives refer to one or more substances used to change the physical, chemical and biological properties of food in the production, processing, storage and other processes of food, so as to enhance the retention period, color, aroma, taste, nutrition, quality stability and other characteristics of food. They can be natural or synthetic. The use of food additives can help make food production and processing more convenient and efficient, while also protecting food quality and safety, and improving taste and appearance.

However, excessive or unnecessary use of food additives may cause potential harm to human health. Therefore, many countries and regions are.

Can you tell us more about that?

Regulate the use of food additives through regulations and standards to ensure the safety and quality of food additives. These regulations and source wide standards usually involve the types of food additives, dosages used, labeling, etc. At the same time, consumers should also understand the types and functions of food additives, and how to choose and use food correctly.

When buying food, it is recommended to pay attention to the additive information marked on the food label to better understand the quality and quality of the food you eat.
