The present invention is oxidized hapyu the tea leaves by productivity increases by a simple production process economically and heated for 5-7 minutes the chaeyeop tea to reproduce the brewed color and flavor and aroma of green tea, especially in the tea at 250 ~ 300 ℃ salcheong step to prevent oxidation by destroying enzyme and, through salcheong step by cooling rapidly the processed tea leaf anti-oxidation and the cooling stage to prevent the discoloration of the tea leaves, the discoloration is prevented tea leaves via the cooling step an ordinary note used by 20 to bibyeoju is noted step for 25 minutes with, the drying step the note to the one via the step tea leaves dried for 30 minutes in a hot air having a temperature of 70 ~ 80 ℃ to dry so that the moisture content comprises a 3-5% by weight and, a sample manufacturing process of manufacturing a sample through a flavoring phase that the flavor of tea flavored by re-heating to the drying step for 85 to 95 to 30 ℃ ~ 40 minutes the dried tea leaves and through Water to cool the manufacturing process by heating the water to 100 ℃ to 80 ℃ to remove the sterilizing and japnae for producing a water and Contains a sample prepared via the Sample Preparation process on sieve of 200 to 300 mesh, and after immersion in the sample 1kg per water 10ℓ the water produced through between the water production process by heating for 2 hours at a temperature of 75 ℃ extract and the extraction process for extracting Concentration step for concentrating the extracted extract to 1/4 through the extraction step, based on the weight of the normal and the concentrator By vacuum packaging and to the concentrated extract using a foil container which light is blocked after sterilization in order to prevent oxidation the 100-110 ℃ straight sterile concentrate block the contact of the oxygen in the air and allow for increasing the shelf life by preventing oxidation provides a sterile packaging process process seismic drink tea extract
