As one of the world's three major non-alcoholic beverages, tea is known as the beverage of the 21st century, and is favored by the world for its natural, nutritious and health-care quality characteristics.
Tea is a special kind of commodity. Incomplete packaging often damages the shape, color, aroma and taste of tea. In order to achieve long-term storage and transportation, tea needs to be packaged effectively.
Tea contains ascorbic acid, tea tannins, tea elements, aromatic oils, proteins, catechins, lipids, vitamins, pigments, pectins, enzymes and minerals. These ingredients are extremely susceptible to deterioration due to moisture, oxygen, temperature, light and environmental odors. Therefore, when packaging tea, the influence of the above factors should be reduced or prevented.
The first thing to be solved is the influence of moisture on tea. The moisture in tea is the medium of tea biochemical changes, and low moisture content is conducive to the preservation of tea quality. Therefore, when packaging, you can choose to use a good moisture-proof performance, such as aluminum foil or aluminum foil vapor-deposited film as the basic material of the composite film as the packaging material for moisture-proof packaging.
Temperature is an important factor affecting changes in tea quality. Tea leaves will aggravate the oxidation of the contained substances at high temperatures, leading to rapid reduction of effective substances such as polyphenols and rapid deterioration of quality. Therefore, its packaging selection should also consider the ability to accept low temperature environments.
Light can promote the oxidation of chlorophyll and lipids in tea, increase glutaraldehyde, propionaldehyde and other odorous substances in tea, and accelerate the aging of tea. Therefore, when packaging tea, light must be shielded to prevent chlorophyll, lipids, etc. The other components undergo a photocatalytic reaction. In addition, ultraviolet light is also an important factor that causes the deterioration of tea.
There is only one choice of packaging material that can meet all the above conditions and the most used packaging material under the same conditions, that is, aluminum foil, which is the packaging material that best meets all the above conditions.
