A process for manufacturing a black leaf tea that is infusible in hot or cold water. The process involves macerating freshly plucked tea leaves, allowing them to ferment, firing the leaves to arrest fermentation and then drying them to yield black leaf tea, wherein the tea leaves are treated with a solubilising compound selected ascorbic acid, dehydroascorbic acid, 1-scorbamic acid, 5-phenyl-3,4-diketo-gamma-butyrolactone (4-phenyl-2,3-diketo-gamma-butyrolactone) or their salts and mixtures thereof in an amount that is sufficient for the black leaf tea to be soluble in water at 5 to 100° C.
一种可在热水或冷水中浸泡的红叶茶的制造工艺。该工艺包括浸泡新采摘的茶叶,使其发酵,焙烧茶叶以阻止发酵,然后干燥茶叶以获得红茶,其中茶叶用一种增溶化合物处理,该化合物选自抗坏血酸、脱氢抗坏血酸、1-抗坏血酸、5-苯基-3,4-二酮-γ-丁酸、抗坏血酸、脱氢抗坏血酸、1-抗坏血酸、5-苯基-3,4-二酮-gamma-丁内酯(4-苯基-2,3-二酮-gamma-丁内酯)或它们的盐及其混合物,其用量足以使黑叶茶在 5 至 100 摄氏度时溶于水。
