GREEN TEA BAG CONTAINING CRUSHED QUARTZ PORPHYRY

摘要

The present invention relates to a green tea bag containing crushed quartz porphyry and, more specifically, to a green tea bag containing crushed quartz porphyry which further purifies green tea by incorporating crushed quartz porphyry with a size of 1 mm to 5 mm into a green tea bag filled with green tea leaves. The green tea bag is obtained by charging crushed quartz porphyry with a size of 1 mm to 5 mm and green tea leaves into a green tea bag filled with the green tea leaves in order to maintain uniform taste of green tea produced from green tea leaves regardless of the condition of green tea leaves by purifying the taste of green tea and the taste of low-quality green tea leaves changed depending on the condition or harvest time of green tea leaves. Because the quartz porphyry charged together with green tea leaves in the green tea bag has a multilayer porous structure with 30,000 to 150,000 per unit area of 1 cm^3, the crushed quartz porphyry removes acerbity or bitterness and precipitates of low-quality green tea due to large surface area, excellent adsorption and degradation capability and thus neutralization of toxicity, antibiosis and deodorization, and alleviates acerbity or bitterness of low-quality green tea by neutralization capability for adjusting acidity or strong alkalinity to weak alkalinity (pH 7.2-7.4), thereby advantageously providing purified green tea.;COPYRIGHT KIPO 2016
