The cup becomes turbid and opaque and has to be changed. For health, drink water to choose the cup, the glass is the choice of most people. However, since the glass is eroded by water for a long time, the sodium silicate reacts with carbon dioxide in the air to form white carbonic acid crystals, which makes the cup dirty and opaque, and it is easy to damage health if it is not replaced for a long time. It is recommended that the "service period" of the glass should not exceed 1 year. White crystals can be washed with alkaline detergent or disinfected with boiling hot water for 10 minutes every week.
Plastic cups are very popular because they are not afraid of falling and light. Plastic products such as PE polyethylene and PP polypropylene are not toxic, but when used in plastic cups, toxic chemicals can easily ooze out. In the water, and inside the plastic, there are a lot of pores, which hide the sundries, and the cleaning is not easy to breed bacteria. Therefore, we must choose a cup made of food grade plastic that meets national standards. Do not use more than half a year, usually avoid ultraviolet radiation, if there is damage or aging, such as cup turbid opacity, should be replaced in time.
Discs and bowls are cracked and deformed. Household dishes and bowls are mostly made of ceramics, and ceramic materials are safe and resistant to high temperatures. It is the best invention passed down by the ancestors. However, if the ceramic tableware is deformed, de-porceled, cracked, etc., it is issuing a replacement signal. Because the beautiful glaze of porcelain contains lead, when there is a crack, lead may overflow into the food.
Families with children like to eat plastic dishes for their babies. Many plastic tableware also have cartoon patterns, which contain metal elements such as lead and cadmium. The general plastic products have a protective film on the surface. Broken, harmful substances will be released. Therefore, it is recommended that the plastic dishes in the home be replaced once every six months, and if there are scratches, they should be eliminated immediately.
Chopsticks will be changed once every 3 to 6 months. The survey found that 92% of household chopsticks have expired service, and many families may have not changed in one or two years. The study found that the longer the chopsticks are used, the higher the total number of bacteria detected, especially in the case of repeated use and washing of chopsticks, the surface will form fine lines, and it is easy to leave bacteria and detergent. It is recommended for 3 to 6 months. Just change it once. Once the chopsticks are found to be scratched, worn or deformed, they must be replaced.
When choosing chopsticks, no matter what material, the most taboo pattern, colorful or uneven surface, it is best to choose the original color (not colored, not painted) and integrated (smooth without nicks, no carving) chopsticks. Because the painting may contain heavy metals, the pigment may dissolve into the food while eating. The uneven surface will hide dirt and become a hotbed of bacteria and mold.
Pay attention to the method when cleaning chopsticks. Do not mammoth or just "shoot a cold bath". Gently wash the chopsticks in a neutral cleaning solution. Do not use alkaline or acidic cleaning liquid such as baking soda or citric acid. So as not to damage the surface of the chopsticks, the outer layer of the waterproof paint will fall off. After cleaning, dry and drain, and place the chopsticks on the chopsticks. Do not touch the tip of the chopsticks when taking it, and it is best to cook the chopsticks once a week with boiling water.
