What are the contraindications for kitchen use

1. Avoid boiling mung beans in an iron pot:

Because mung beans contain tannins, black tannin iron will be generated when exposed to iron at high temperatures, which makes mung bean soup black and has a special smell, which not only affects appetite and taste, but also harms the human body.

2. Avoid boiling traditional Chinese medicine in stainless steel or iron pots

Because traditional Chinese medicine contains a variety of alkaloids and various biochemicals, especially under heating conditions, it will have a variety of chemical reactions with stainless steel or iron, or make the drug ineffective, and even produce certain toxicity when there are many complexes.

3. Avoid using aluminum pots to serve dishes:

Aluminum pots are obsolete kitchen utensils. Because of its poor corrosion resistance, chemical reactions will occur in case of weak alkali, weak acid, salt and other substances to form special compounds, so dishes, wine, monosodium glutamate, etc. should not be packed in aluminum containers overnight. Also, eggs should not be stirred in an aluminum pan, because the egg whites will turn gray-white when they encounter aluminum, and the egg yolks will turn green.

Leftover rice, leftover soup, etc. should also not be left overnight in aluminum containers.

Fourth, avoid using black cedar wood or odorous wood to make cutting boards:

Ebony cypress contains peculiar smell and toxic substances, and the smell of using it as a cutting board not only contaminates the dishes, but also easily causes vomiting, dizziness, and abdominal pain. Therefore, the preferred wood for folk cutting boards is white fruit wood, saponaria wood, birch and willow wood.

5. Do not use painted or carved bamboo chopsticks

The paint applied to chopsticks not only contains chemicals such as lead and benzene, which is harmful to health, but also has a peculiar smell when heated, which affects appetite. The carved bamboo chopsticks look beautiful, but they are not easy to clean, breed bacteria, and are easy to cause disease.

Sixth, avoid using all kinds of color porcelain to hold condiments:

Condiments are best served in glassware. Benzene and other pathogenic and colored porcelain contain lead and carcinogens. With the aging and decay of color porcelain, the "radon" in the pattern pigment contaminates food and is harmful to the human body.

7. Metal containers should not contain acidic drinks

When an acidic beverage comes into contact with a metal container (iron, aluminum, copper, etc.), a chemical reaction occurs, causing the metal substance to dissolve in the beverage. Once this drink is consumed, it can cause chemical food poisoning, headaches, nausea. Symptoms such as diarrhea, while drinks such as lemonade, orange water, and sour plum soup are highly acidic.

Therefore, metal containers should not contain acidic beverages.

Do not use black cypress cutting boards. People always think that the black cypress cutting board is easy to use, but they don't know that it contains a kind of lignotoxin, this cutting board is soaked in water, it will ooze a black toxin, if the cut vegetables are stained with toxins, people will cause vomiting, convulsions or abdominal pain when they eat it, so the cutting board should be used willow, ginkgo trees and the like.

Do not use a marinated jar or jar to hold rice. Rice is served in a marinated jar or in a jar that has no fishy smell, so that the rice can easily absorb the odor or peculiar smell on these containers, and the rice made with this kind of rice has a strange smell and is not delicious. Therefore, it is better to use breathable utensils for rice, such as rice baskets and buckets.

Do not use an iron pot to cook lotus root. Boiling lotus root in an iron pot will cause a chemical reaction, and after boiling the lotus root in an iron pot, it will turn black, and people will not only not play the role of nourishing and clearing heat, but will cause gastrointestinal discomfort. Therefore, it is better to use a casserole to cook lotus root.
