    Flavanol composition and caffeine content of green leaf as quality potential indicators of Kenyan black teas 

    Obanda, Martin; Owuor, P Okinda; Taylor, Sarah J (1997)
    The Ñavanol composition and ca† eine content of green tea leaf, black tea quality parameters of theaÑavins, thearubigins, liquor brightness and total colour varied more among clones than with time of the year. In green ...

    Influence of region of production on clonal black tea chemical characteristics 

    Owuor, P Ok; Obanda, Martin; Nyirenda, Hastings E; Mandala, Wilson L (2008-05-01)
    Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and Malawi, shows variations in both chemical composition and quality. Whereas it is possible to produce black teas with similar ...

    The use of green tea (Camellia sinensis) leaf flavan-3-ol composition in predicting plain black tea quality potential 

    Owuor, P O; Obanda, Martin (Elsevier, 2007-12-13)
    Reliable and quantifiable green leaf parameters for predicting black tea quality potential of tea bushes at the single bush stage are necessary to shorten tea breeding and clonal selection programmes. Green leaf ...

    The changes in black tea quality due to variations of plucking standard and fermentation time 

    Owuor, P O; Obanda, Martin (Elsevier, 1998)
    Catechin levels in green leaf, total theaflavins, brightness, thearubigins, colour, flavour index and sensory evaluation decrease with coarse plucking standard in clone 6/8. The sum of Group I volatile flavour compounds ...
    Thumbnail

    Clonal plain black tea quality parameters responses of hard physical withered leaf to rehydration and fermentation durations 

    Owuor, P Okinda; Obanda, Martin (2016-04-16)
    Hard physical withers in tea processing result in reduced plain black tea quality parameters, but improve flavoury black tea quality. Chemical withers with minimal moisture loss improve plain black tea quality parameters. ...

    The changes in black tea quality due to variations of plucking standard and fermentation time 

    Owuor, Phillip O; Obanda, Martin (Elsevier, 1998-04)
    Catechin levels in green leaf, total theaflavins, brightness, thearubigins, colour, flavour index and sensory evaluation decrease with coarse plucking standard in clone 6/8. The sum of Group I volatile flavour compounds ...

    Clonal variation in the individual theaflavin levels and their impact on astringency and sensory evaluations 

    Owuor, Phillip O; Obanda, Martin (Elsevier, 1995-01-01)
    Clonal variation in the individual theaflavin levels and their impact on astringency and sensory evaluations
    Thumbnail

    Comparative responses in plain black tea quality parameters of different tea clones to fermentation temperature and duration 

    Owuor, Okinda P; Obanda, Martin (Elsevier, 2001-02-01)
    The amounts of black tea theaflavins, brightness, and sensory evaluations varied with clones in the order clone 6/8>SC12/28>S15/10, while thearubigins and total colour changed in the reverse order. The rates of change of ...

    Influence of region of production on clonal black tea chemical characteristics 

    Owuor Okinda, P.; Nyirenda, Hastings E.; Obanda, Martin; Mandala, Wilson L. (Elsevier, 2008-05-01)
    Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and Malawi, shows variations in both chemical composition and quality. Whereas it is possible to produce black teas with similar total ...

    The relationship between some chemical parameters and sensory evaluations for plain black tea (Camellia sinensis) produced in Kenya and comparison with simila... 

    Owuor, P O; Obanda, Martin; Nyirenda, Hastings E; Mphangwe, Nicholas IK; Wright, Louwrance P; Apostolides, Zeno (Elsevier, 2006-08-31)
    Reliable and accurately measurable chemical parameters that can be used to estimate black tea quality are desirable in trade, research and breeding programmes. Using plain Kenyan black tea from 11 cultivars, which gave ...
