Using glass to change into plastic food containers should be noted to avoid poisoning the whole family

Overcoming the disadvantages of plastic and glass is an extremely safe and suitable choice for everyone to store food. However, experts recommend that a number of things to be aware of when using glass, to avoid harm to health.

Not believing in the quality of the plastics that are widely sold in the market, Mai Ngoc Gam (34 years old, living in District 9, Ho Chi Minh City) mostly uses glassware to store food in the family. . From food containers, cups, plates, bottles of drinking water to pots, pans, everything is made of glass."Plastic now has many types, many different prices but the quality is not verified. My family has young children and older parents, I do not feel comfortable using plastic items in the family , " she said. Damn said.

Benefits of glass in cooking, preserving food

Analyzing glass materials, Dr. Duong Thi Kim Loan, head of the Department of Nutrition and dieting, Thong Nhat Hospital said that this is a homogeneous amorphous solid, based on silica (silicon dioxide, SiO ₂ , or from quartz), is often mixed with impurities to give the desired properties.

In its pure form and under normal conditions, glass is a substance with a very high thermal resistance, transparent, relatively hard, difficult to wear, very chemically inert and inactive biologically, having Can form with very smooth and smooth surfaces.

Although glass is a safe material to store food, people still need to take care when using it.

Glass is widely used in many fields. One of them is the field of food preservation, containers, cookware such as: glass containers, glass bottles, glass jars, cups, cups, glasses, glass cups, glass pots, pots, kettles Glass tea, glass-sided kitchen . extremely rich.

"Glass is a non-porous, natural material. Glass containers of food never leak and are safe to use many times. Moreover, the melting point of the glass is very If you put hot food in glass containers, you won't worry about toxic substances coming in. The containers of non-quality plastic can warp when exposed to hot food. glass is not. So when hot food is put into glass containers, there is no need to wait for the food to cool down. The glass is easy to clean and makes it difficult to deposit bacteria like other materials. " Loan doctor analyzed.

Glass is easier to clean and bacteria than other items.

The note when using glass to avoid health damage

Although safe, overcoming many disadvantages of other food containers, however, the drawback of glass lies in the fact that glass is very fragile or broken into sharp and sharp pieces under the influence of force or sudden heat. Specific types of glass will withstand heat at specific temperatures. Using glass with poor heat resistance and containing hot foods or boiling water is dangerous, especially in families with young children.

"The most noticeable thing is when the impact is small, the small pieces of broken glass can be mixed with food or drinking water, hard to see with the naked eye. If unfortunately eat or drink, it will be very dangerous. " , an expert in nutrition analysis.

Also be wary of certain types of glass that may contain lead. The Department of Quality Control for Goods and Products (the General Department of Standardization, Metrology and Quality) once recommended not to use colorful and patterned glass mugs, because most of the samples were tested. Experiments have shown alarming results (the product contains many times higher lead content).

Be aware of some lead-free glass cups.(Illustration).

In many tests of the authorities, the poor quality goods in the market are very large, the samples taken for testing have results containing lead toxin (Pb), metal. cadmium heavy (Cd) is thousands of times higher than the reference standard.

Even samples containing heavy metal toxin content Cd exceed the permissible level more than 600 times; contain Pb level exceeding the permitted level nearly 4,000 times.

According to the research conclusion of scientists, the content of toxins in glass products when taken into the body, the amount of lead will release free radicals, penetrate the parts, accumulate in bones , affecting the nervous system, blood . causing severe intoxication.

In particular, if infected with Cd for a long time, children may develop rickets, bone growth retardation; Elderly people with osteoporosis, even death. Therefore, the current best measure for consumers is to say 'no' to the glass products with pictures, patterns, bright colors on the outside, without specifying the origin; Do not specify the content of lead on the surface and the price is too cheap.

In order to use safe glass, Dr. Loan recommends that consumers pay attention to the quality of the glass, choose from reputable manufacturers, buy products of origin and origin, ensure that durable of products."Should choose the white glass, avoid buying colored ones, prioritize choosing items with round, straight shapes, avoid buying items with many textures, difficult to clean and break easily when there is a collision. touch. It should be noted when using glass to store food for children, note that these items are on high, to avoid the reach of children to prevent collapse, causing harm to the baby " , Doctor Loan emphasized.
