Li Hongzhu, associate researcher of Tianjin Pharmaceutical Research Institute, said: “color straws contain more synthetic dyes than colorless transparent straws. The brightly colored dyes contain a lot of heavy metals such as lead and cadmium and diazo poisons. These ingredients can cause diseases for people with low immunity.”
According to Li Hongzhu, the ingredients of inferior straws are unknown, and some bad businesses even use recycled raw materials. Once the sterilization is not complete, it will cause serious damage to the liver and kidney, and seriously affect the nervous system and children’s intellectual development.
As an edible tool, the straw is non-toxic and can withstand a high temperature of 100 degrees. The state stipulates that only polypropylene can be used as a straw. However, some businesses use inferior and low-grade polyethylene, and even industrial raw materials such as polyvinyl chloride. These materials have poor heat resistance, and will become soft in hot water above 60 degrees, releasing toxic and harmful components.
In addition, when the liquid in which the straw is immersed is acidic liquid such as fruit juice and carbonated beverage, the dye of the color straw will dissolve in the beverage. Plasticizers, fluorescent agents and other chemicals contained in some “cartoon straws” and “fun straws” have also become potential “carcinogens”.
In daily life, we can’t avoid using straws. Li Hongzhu suggested that when choosing straws, we should “look, smell and choose”.
take a look
Try to choose transparent and colorless straws. There will be a lot of dyes added to red and other colorful straws. In addition, aim the straw at the light to check whether the wall of the tube is uniform and free of impurities, which may be made of inferior plastic.
Erwen
Smell whether there is a strong plastic smell. If the plastic smell is very strong, be aware that the straw may be added with PVC or made of recycled plastic.
three choices
Select the straw with QS mark on the package. The inner package of the straw product shall have obvious marks, such as the batch number, material, specification, production date and address of the product.
Consumers should try to buy straws from large supermarkets and regular businesses, and avoid using straws provided by roadside stalls and beverage stores. In use, it should also be avoided to use with carbonated drinks, milk, soymilk and other hot drinks.
