Abstract: The present invention relates to a process for manufacturing a black leaf tea product, the process comprising: providing black leaf tea material having a moisture content of less than 20 wt. %; and then subjecting this black leaf tea starting material to a heat treatment step by contacting it with a heated surface at a temperature of 60° C. to 100° C. in the presence of steam for a duration of at least 2 minutes.

Abstract: One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.

Abstract: The present invention relates to a process for manufacturing a black leaf tea product, the process comprising the steps of: providing black leaf tea having a moisture content of less than 5 wt. %; and then subjecting this black leaf tea starting material to a heat treatment step by contacting it with a heated surface at a temperature of 100° C. to 170° C. for a duration of 2 to 25 minutes. The present invention also relates to a black leaf tea product obtainable by this process.

Abstract: A process for producing tea products is provided, the process comprising: providing fresh whole tea leaves; placing the tea leaves into a press, and pressing the leaves thereby producing tea juice and leaf residue, whilst applying steam to the outside of the press, so that the steam comes into contact with the juice as it leaves the press; collecting the juice; and processing the leaf residue to produce black tea. A green tea product obtainable by the process of the invention is also provided. The product contains greater than 3.0% theanine by weight of the total tea solids and has a weight ratio of theanine to total polyphenols of less than 1:6.

Abstract: Disclosed is a process comprising the steps of: expressing juice from a supply of fresh tea leaves thereby to produce leaf residue and tea juice; subjecting the supply of fresh tea leaves and/or the tea juice to a fermentation step thereby to at least partially ferment the tea juice; and combining the at least partially fermented tea juice with substantially unfermented tea material comprising active endogenous enzymes, thereby to form a mixture; and subjecting the mixture to an enzyme deactivation step thereby to prevent fermentation of the substantially unfermented tea material in the mixture.

Abstract: Disclosed is a tea-based beverage comprising expressed tea juice, wherein the beverage has a total aluminium content of less than 8 ppm; a total fluoride content of less than 8 ppm; or both.

Abstract: Disclosed is a process comprising the steps of: a) heating fresh tea leaves; and b) expressing juice from the fresh tea leaves whilst the temperature of the fresh tea leaves is greater than 40° C. and less than 77° C., thereby to produce leaf residue and tea juice.

Abstract: Disclosed is a process for manufacturing a green leaf tea product, the process comprising the steps of:—providing fresh tea leaves comprising catechins and active endogenous enzymes;—comminuting the fresh tea leaves comprising active endogenous enzymes under aerobic conditions sufficient to cause substantial bruising to the leaves;—inactivating the endogenous enzymes in the comminuted fresh tea leaves to substantially prevent fermentation of the fresh leaves;—and drying the comminuted fresh tea leaves to yield the green leaf tea product.

Abstract: Disclosed is a process comprising the steps of: expressing juice from a supply of fresh tea leaves thereby to produce leaf residue and tea juice; subjecting the supply of fresh tea leaves and/or the tea juice to a fermentation step thereby to at least partially ferment the tea juice; and combining the at least partially fermented tea juice with substantially unfermented tea material comprising active endogenous enzymes, thereby to form a mixture; and subjecting the mixture to an enzyme deactivation step thereby to prevent fermentation of the substantially unfermented tea material in the mixture.
