Technical Field

The invention belongs to the field of antioxidants, and relates to an antioxidant for tea.

Background

The tea is easy to deteriorate in quality during storage, so that the drinking value and the commodity value of the tea are reduced. The environmental factors influencing the quality change of the stored tea mainly include moisture, oxygen, temperature, light and the like. The packaging material is easy to transmit oxygen and moisture in the storage process due to certain oxygen transmission rate and moisture transmission rate. Water is a medium of chemical reaction, the oxidation degradation speed of biochemical components of the tea is directly determined by the moisture content, and the moisture content is an internal leading factor of the quality change of the tea. Production units generally keep fresh only by low-temperature refrigeration or vacuumizing during sale, water is easy to absorb at normal temperature after the low-temperature refrigeration is taken out of a warehouse, and the quality deterioration speed of the tea is accelerated due to the increase of the moisture content and the sudden rise of the temperature. Moisture and oxygen entering the package during relatively long storage and distribution undergo a series of oxidation reactions with the biochemical components of tea leaves, resulting in a reduction in the quality of the tea leaves. Therefore, an antioxidant with good effect and no toxic and side effects is needed for the antioxidation and the fresh-keeping storage of the tea.
