1. aluminium pot avoid long - term serving meal
Aluminum is very reactive and oxidizes easily in the air to form a thin film of alumina.Alumina film is insoluble in water but soluble in acidic or alkaline solutions.Salt also destroys alumina.If the soup and vegetables are kept in aluminum containers for a long time, not only will the aluminum products be destroyed, but more aluminum molecules will be dissolved in the soup.These aluminum molecules and foods undergo chemical changes to produce aluminum compounds.
Long-term consumption of foods containing large amounts of aluminum and aluminum compounds will damage the normal proportion of calcium and phosphorus in the human body, affect the growth, development and metabolism of human bones and teeth, as well as affect the activity of certain digestive enzymes and weaken the digestive function of the stomach.Therefore, aluminum pot bogey long dish.It's also best not to use an aluminum pan to fry vegetables or to cook soup.
2. Don't drink acidic beverages in metal containers
When acid drinks are in contact with metal containers (iron, aluminum, copper, etc.), a chemical reaction will occur to dissolve the metal in the beverage.Once consumed, it can cause chemical food poisoning, headaches and nausea.Diarrhea and other symptoms, and lemon water, orange water, such as plum soup drink acidity is high.Therefore, metal containers do not contain acidic beverages.
3.Plastic utensils should contain no oil and grease
The contraindication that plastic food utensils USES: avoid cheng fang to put food too long, should wash to put immediately after using every time.Avoid fat.Because the soft plastic food is poor in oil resistance, easy to oil pollution.
Avoid fresh fish.Due to the strong absorption characteristics of soft plastic food, it is difficult to remove the fishy taste after putting fresh fish.Avoid water in full bloom.Soft plastic food is not resistant to high temperature shortcomings, bogey installed with boiling water or hot water bubble.
4.Avoid using enamel products to boil food
Enamel products of all kinds are made by enameling the exterior of iron products with enamel.Enamel contains lead, which is harmful to human health.
To be safe, it is best not to use enamel products for cooking, nor to use it for serving acidic foods.Because enamel products are coated with glaze, its main composition is a variety of metal salts, such as yellow, bright red glaze is cadmium and lead compounds, and lead and cadmium are toxic.Use colorful enamel products containing acid food, lead and cadmium and other toxic substances will dissolve into the food and cause chronic poisoning.
5.Avoid using colored porcelain tableware to serve acidic food
The ceramic tableware with colorful patterns will give the diner a beautiful enjoyment.But little is known about the potential dangers.
Whether painted on porcelain or pottery at high or low temperatures, they are pigments composed of some toxic heavy metals and other compounds, such as the bright red of the glaze, mostly cadmium containing compounds, the cream yellow with lead oxide, and the emerald green with chromium oxide.When serving weakly acidic food such as fruit juice, vinegar and wine in such porcelain vessels, the toxic heavy metals in colored porcelain glaze flowers will be dissolved, and enter the human body with food, causing damage to the body, and even causing chronic poisoning. Cadmium poisoning can cause lung and bone damage.Lead poisoning can cause anemia, neurasthenia, bone marrow hyperplasia and other diseases.So for color porcelain.The tableware such as coloured pottery, especially the tableware that the inside wall has coloured glaze design must not be used.
6.Avoid stainless steel or iron pot decoction of Chinese traditional medicine
Because traditional Chinese medicine contains a variety of alkaloids and various biochemical substances, especially under heating conditions, it will have a variety of chemical reactions with stainless steel or iron, or make the drug ineffective, or even produce a certain toxicity.
7.Do not use smelly wood for cutting board
The first choice wood that folk makes board is white fruit wood, saphorn, birch and willow.Some wood, such as cedar wood, contain odors and toxins that can be used to make boards that not only contaminate dishes, but can also cause vomiting, dizziness and abdominal pain.
8.Avoid using painted or engraved bamboo chopsticks
The paint that besmears on chopsticks not only contains chemical substance such as lead, benzene, harmful to health, and meet hot hind smell, affect appetite.
The carved chopstick looks beautiful, but it is easy to hide dirt, not easy to clean, breeding bacteria and even causing disease.
9. Avoid using various kinds of colored porcelain for seasoning
The ingredients are best served in glass.Porcelain ware contains carcinogens such as lead.With the aging and decay of porcelain, the radon in the pattern pigment can also pollute food and harm human health.
