In life, some housewives often "sub pack" large quantities of soy sauce, vinegar and edible oil with empty mineral water bottles. Nutrition experts point out that such a "reuse" method is not desirable.

Plastic bottles of mineral water are generally made of polyethylene. Such containers are only suitable for storing drinking water at room temperature, not for canned hot water or edible seasoning, because polyethylene will slowly dissolve and release an organic solvent harmful to human body after being corroded by high temperature or acidic solution. When this organic solvent is mixed with the water or seasoning in the bottle, It may cause dizziness, headache, nausea and other adverse reactions.

Nutrition experts suggest that condiments such as edible oil, soy sauce and vinegar be packed separately. The prohibited words are brown glass bottles, which can effectively prevent the condiment components in the bottles from being oxidized.
