Tea Bags: Design Charm


Editor's Note: Tea is a traditional drink that our people have been drinking for thousands of years. It has now become one of the three non-alcoholic beverages that have become popular in the world. When you rush for a cup of tea, the color of the beautiful jasper, the fragrant fragrance of people, with a bitter taste, a variety of tea-shaped, make people pleasing.

As one of the world's three major non-alcoholic beverages, tea is hailed as a beverage of the 21st century and has been favored by the world for its natural, nutritious and health-care qualities. Tea as a special kind of goods, the incomplete packaging often causes the shape, color, smell and taste of tea to be damaged. In order to achieve long-term storage and transportation, tea needs to be effectively packaged.

Tea storage>>>

The method of tea storage is determined according to the quality characteristics of tea and the main factors that affect the chemical changes in tea storage. Tea has hygroscopicity, aging, and odor absorption. The main factors influencing the chemical changes in tea storage are temperature, humidity, oxygen, light, odor, etc. Therefore, no matter what place, equipment or material is used for storage, it must have low temperature. , dark, dry, confined, no odor and other conditions. Introduce several methods of tea storage and preservation for reference.

1. Dry storage teas have strong hygroscopicity. When water is high, they are easily oxidized and deteriorated. Therefore, the tea must be dried (water content is less than 6%) and then stored. The storage container must be filled with an appropriate amount of moisture absorbing agent such as lime or dry charcoal to prevent dampness. (Limes and tea have a volumetric ratio of 1:3, ie, 1/3 of the container contains lime or charcoal, and 2/3 places tea.

2. When stored at low temperature, the tea leaves are qualitatively slow at low temperatures, and are easily degraded at high temperatures. Therefore, the tea must be stored in a low-temperature ventilated place, and the tea-filled container can be sealed in a refrigerator or a cold store in a conditional manner.

3. Moisture-proof storage Moisture-proof packaging is a packaging method that uses a good moisture-proof packaging material and a desiccant to prevent the tea from absorbing water. Commonly used moisture-proof packaging materials are polyester/polyethylene, cellophane/polyethylene, nylon/polyethylene, polyester/aluminum foil/polyethylene, and tin/ceramic jars. The desiccant is usually silica gel or specially made lime of higher purity. The ratio of tea to silica gel is about 10:1, and the tea and lime are 3:1.

4. The infrared light stored in the light will increase the temperature of the tea leaves, and the ultraviolet rays will cause the photochemical effect, thereby accelerating the qualitative change of the tea. Therefore, we must avoid storing tea under strong light, but also avoid packaging tea with light-transmitting materials; for example, using glass bottles or translucent food bags to store tea leaves should be selected as a brown tea.

5, sealed storage oxidation reaction is the essential process of tea quality, if you cut off the oxygen supply can stop the oxidation inhibition of qualitative change. Therefore, it is necessary to seal the stored tea with oxygen. Can be used tin cans, ceramic jars, food bags, hot water bottles and other sealed containers for storage of tea, the container should be lined with food film bags, as little as possible to open the container mouth, seal the bag when the air out of the liner, in order to reduce the oxidation of tea Deterioration. Oxygen-inflated bag bags can be used to store tea leaves.

6, vacuum storage vacuum packaging storage is the use of vacuum packaging machine, the tea bag air immediately after the pumping seal, so that the bag inside the vacuum state, so as to retard the oxidative deterioration of tea, to achieve the purpose of preservation. Vacuum packaging, the choice of packaging bag container must be a good gas barrier (oxygen barrier) performance of aluminum foil or other two or more composite film material, or iron, aluminum cans and other quality.

7. The tea leaves stored separately have extremely strong adsorption properties. For example, they can be used together with camphor and gasoline to immediately adsorb the gas. Therefore, tea should be stored separately. Containers containing tea leaves must not be mixed with other items. Storehouses storing tea should not be mixed with other materials. In addition, tea should not be stored in odor-evaporated containers or odor-absorbed containers.

8, nitrogen storage and use of inert gas carbon dioxide or nitrogen to convert the tea packaging bag of active oxygen and other air, block the chemical composition of tea and oxygen reaction, to prevent tea aging and deterioration. In addition, the inert gas itself also has the effect of inhibiting the growth and reproduction of microorganisms. The air in the bag is then removed to form a vacuum, and nitrogen gas is then filled with inert gas such as carbon dioxide, which is sealed tightly.

If these methods are used together, they will achieve good results.
