First of all, the source of the chopping block
Yuan? Guan Hanqing? The third fold of Wangjiang Pavilion: "You bring the chopping block and knife, and I'll cut it." Go back to the 42 nd episode of Wake Up Marriage: "All I can hear is the sound ... or the anvil on my spine is ringing wildly, or it's like a chopping block chopped up by several knives." ? Qinghe bango? "Twelve Years of Night Talk": "I saw the monk's donkey chest yesterday and put it on the chopping block in the kitchen." Tian Han? In the second act, the two men said, "We have all become the meat on the chopping block of the invaders."
In restaurants or hotels, chopping boards are also called work, which is responsible for cutting food, and some are also called "chopping piers".
Second, the classification of chopping block
There are plastic chopping boards, wooden chopping boards, bamboo chopping boards, flat tempered glass, etc. The best chopping board material is alder.
The best material for chopping block-Alnus cremastogyne, also known as fire wood, evergreen tree, endangered species. It is distributed in monsoon forest, a tropical limestone mountain with an altitude of 700 to 900 meters in Guangxi and Yunnan. The distribution center of this species is in the south of Guangxi, extending to the limestone area in the southeast of Yunnan to the west, and crossing the Tropic of Cancer to the north, it gradually becomes an occasional species and disappears. In Yuanjiang, it is the northern edge of this species distribution, which is relatively rare. Young trees are shade-tolerant, and trees older than 10 need full sunlight. It blooms in March, and the fruit matures in June, with an interval of 2-3 years. It is one of the constructive species of the primitive limestone seasonal rain forest in the north tropics, and it is a unique plant of tropical limestone, which has important research value. Its wood is heavy and has good mechanical properties. It is a precious material for machinery, special buildings, shipbuilding and high-grade furniture, and also a good material for chopping boards.
Third, the difference between different chopping boards
Cutting boards made of different materials have their own characteristics, but wooden cutting boards are relatively safer because they are natural and have no other substances added. Therefore, it is recommended that citizens give priority to using natural wooden chopping boards.
The wooden chopping block has high density and strong toughness, and it is very firm to use. However, it is not easy to choose wooden chopping boards because of their various types. Some wooden chopping boards (such as Ubuntu) contain toxic substances and have an odor. Cutting vegetables with them will pollute the dishes and easily cause vomiting, abdominal pain and dizziness. There are also some loose wooden cutting boards, such as poplar cutting boards, which are not hard enough, easy to crack and prone to knife marks on the surface. If it is not thoroughly cleaned, it is easy to shelter evil people from evil practices, breed bacteria and pollute food. Therefore, it is suggested that citizens choose chopping boards made of ginkgo, acacia, birch or willow with good comprehensive quality in all aspects. The public should not buy the "three noes" chopping boards in the hands of small vendors, and the chopping boards produced by regular manufacturers will be marked with wood. You'd better smell the chopping block before you buy it. If it smells sour, it probably contains sulfur. Don't buy it. There are also some vendors selling wooden chopping boards, which are whiter than ordinary wood. In order to reduce the cost, the chopping boards produced by these small workshops are all made of inferior wood and look "dark". In order to whiten the chopping block, sulfur fumigation is usually used for bleaching, and the residual sulfur dioxide will seriously harm human health.
Bamboo chopping block is slightly lighter than wood, so it is not easy to fake, its quality is relatively stable and it is safer to use. However, its density is not as good as that of wooden chopping boards, and its thickness is not enough. Most of them are spliced and cannot be struck hard when used. A small number of board faces in the market are all bamboo. This kind of chopping board does not use chemical reagents and is not easy to crack, but its price is slightly higher, so it is a new choice for health and environmental protection.
Although the plastic cutting board is light in weight and convenient to carry, it is easy to deform. Pay attention to it when you buy it, and touch it with your hands. Some rough plastic cutting boards are easy to cut out slag foam, which enters the human body with food and causes damage to liver and kidney; Some dark plastic cutting boards are mostly made of waste plastics, and there are many harmful substances. Therefore, it is best to choose a plastic cutting board with translucent color, good quality, uniform color, no impurities and pungent smell.
Fourth, how to use the chopping block
1. Before using the chopping block, rinse it with clear water to wash off the dust on the chopping block.
2. Rinse the chopping block again after use, wipe it with a rag, hang the chopping block on the wall or use YCZM tripod to stand upright in the shade to dry it, so as to avoid discoloration or mildew of the chopping block due to moisture.
3. Don't use detergent to clean, because the cleaning liquid will penetrate into the chopping block, which will lead to moldy chopping block for a long time, and it is quite unsanitary to use it to treat food.
4. If the chopping block has been treated with heavy oil, you can scrub it with hot water and remove the oil quickly (remember not to use a pot brush).
5. When there is fishy smell or other peculiar smell on the chopping block, you can clean it with lemon and coarse salt. When the chopping block has cracks or black spots, it should be thrown away.
6. Be careful not to put the chopping block in direct sunlight, so as to avoid the chopping block from cracking due to excessive drying.
7. If you are in the kitchen for a long time, it is recommended to buy two cases, and use raw meat and cooked meat separately to reduce the cross-breeding of food bacteria.
Cutting board crack prevention tips? Coincidentally, the newly bought chopping block should be coated with cooking oil immediately. The practice is to apply cooking oil on the upper and lower sides and around the chopping block, and then apply it three or four times after absorbing the oil. The cutting board is easy to crack around, so you can apply it several times repeatedly until the oil is dry. After this treatment, the chopping block is not easy to crack.
Five, the use of chopping block matters needing attention
When using plastic cutting board, it is best not to cut very hot cooked food, because high temperature will accelerate the precipitation of harmful substances; After each use, it is best to rinse with hot water at 50-60℃ and dry it immediately after washing. Other cutting boards should also be cleaned and dried in time after cutting vegetables. After cleaning, it should be placed vertically or hung in a ventilated place. Don't put it close to the wall, and don't lay it flat, otherwise the other side can't be dried, which is easy to breed pathogenic bacteria such as mold. After cutting wood and bamboo chopping boards every day, it is also best to disinfect them. The following methods can be adopted: washing and ironing, scrubbing the chopping board with a stiff brush and clean water, scalding it with boiling water, and drying it in the sun to prevent bacteria from having a habitat; Scraper dipping method, after each use of the chopping block (especially after cutting meat), scrape off the food residue and juice on the surface, scrub with clear water, then soak in salt water (concentration about 15%) for 2 hours, and then take it out to dry, which can not only sterilize, but also prevent the chopping block from cracking.
Sanitary condition of chopping block
The chopping block is an excellent place for bacteria to hide. The uneven knife marks on the board are nutritious, dark and humid, just suitable for the survival and reproduction of bacteria. Someone looked at it with a microscope and found that there were 2 million Staphylococcus aureus, 1 10,000 coliforms and other bacteria on each square centimeter of drilling board.
Most families in our country are used to cutting lettuce and cooked vegetables with the same chopping board. Cutting cooked food on these bacterial chopping boards will naturally get a lot of bacteria, and then the population will enter the gastrointestinal tract, causing systemic diseases such as digestive system. Therefore, paying attention to the hygiene of the chopping board is an important part of food hygiene.
Sterilization and disinfection method
At present, the most common sterilization methods for chopping boards are as follows:
First, scraper, salt. Scrape off the residue on the chopping board every time after cutting vegetables, and sprinkle a layer of fine salt on the chopping board every week, which can not only sterilize, but also prevent the chopping board from cracking;
Second, boiling water. Rinse with a stiff brush and clean water, and then rinse with boiling water;
Third, drug disinfection. Add two pieces of bleaching powder to five kilograms of water and soak the chopping block for a quarter of an hour.
In fact, the chopping block is only a small object in our kitchen, but its use is also orderly and exquisite. After all, the disease comes from the mouth. You must be careful what you eat in your stomach to keep it clean and hygienic. So we can't ignore the details in life, sometimes a change in details can improve our quality of life!
