Oily film on tea: what it really is and how to avoid it.

According to ТСН: Many people believe that the film on the surface of tea is a residue of pesticides. However, experts emphasize: modern plant protection products practically do not leave residues in tea. In reality, this film forms due to the reaction of tea polyphenols with calcium salts in the water and oxygen from the air.

Main reasons for the appearance of the film:

1. Water quality: a high content of calcium and magnesium contributes to the formation of a thin coating.

2. Oxygen content: the more oxygen in the water, the faster the film forms.

How to brew tea without the oily film:

• Use soft water - filtered or bottled.

• Add a drop of lemon or orange - this slows down the formation of the film.

Important: this film is completely safe and does not harm health, although it can affect the taste of the beverage. If you want your tea to look better and have a more pleasant taste, follow simple rules regarding water quality and the correct brewing temperature.

Understanding the reasons for the appearance of the film on tea will help consumers better control this process. Depending on the choice of water and the amount of oxygen, both the quality and the aesthetics of the drink can be significantly improved. So don't be afraid to experiment with making tea to find the best option for your preferences.
