Abstract: The present invention relates to a process for aroma recovery from tea leaf including the steps of: incubating fresh tea leaf at a temperature in the range 4 to 80° C. under anaerobic conditions for a period of 4 to 72 hours; subjecting the incubated leaf to comminution to produce dhool; fermenting the comminuted dhool; and recovering aroma from the dhool while partially drying the dhool in a low-convection dryer.

Abstract: The present invention relates to a process of producing a green leaf tea. More particularly the present invention relates to a process of producing a green leaf tea with higher soluble solids and unique aroma characteristics. Accordingly, the present invention provides a process of preparation of green leaf tea product comprising the steps of: a. incubating fresh tea leaf at a temperature in the range 4° C. to 80° C. under anaerobic conditions for a period of 4 to 72 hours; b. subjecting the incubated leaf to a step of thermal treatment at a temperature in the range of 60° C. to 250° C. for about 15 seconds to 60 minutes; c. drying the leaf to a moisture content less than 8% by total mass of the tea leaf to obtain a green leaf tea.

Abstract: The present invention relates to a tea product and more particularly the present invention relates to a black tea product. According to the present invention there is provided a process for producing a tea product comprises the steps of: a) extracting a leaf tea product including both a soluble part and an insoluble part with a solvent; b) separating the insoluble part from the soluble part; c) compacting the insoluble part to obtain a base tea material; d) drying the base tea material to a moisture content of less than 5% by weight. e) contacting the soluble part obtained in step (b) with the dried base tea material; f) further drying the mixture to obtain the tea product.

Abstract: Disclosed is a process for the enzymatic preparation of a gamma-glutamyl compound. The process comprises a step of contacting a gamma-glutamyl donor and a gamma-glutamyl acceptor with an aqueous medium comprising a gamma glutamyl transpeptidase enzyme. The enzyme is derived from a plant belonging to the Graminaceae or Leguminaceae family, or from Camellia sinensis.
