Changes in the chemical and sensory quality parameters of black tea due to variations of fermentation time and temperature
(Elsevier, 2001-12-31)
The changes in theaflavins and residual catechin compositions, thearubigins TRSI and
TRSII, sensory characteristics of total colour, brightness and briskness of black tea were
investigated. It was demonstrated that the ...
The use of green tea (Camellia sinensis) leaf flavan-3-ol composition in predicting plain black tea quality potential
(Elsevier, 2007-01-01)
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 flavan-3-ols ...
Effects of cation siting and spin–spin interactions on the electron paramagnetic resonance (EPR) of Cu2+ exchanged X Faujasite zeolite
(North-Holland, 2006-11-21)
Copper(II) exchanged Na X Faujasite zeolite was cation exchanged at levels from one Cu(II) in 30 unit cells (0.033 Cu(II)/UC) to 38 Cu(II) per unit cell (38 Cu/UC) and was examined by continuous wave and two-pulse and ...
Spectroscopic characterization of the metal cation siting and the adsorbate-cation interactions in copper (II) and cobalt (II) exchanged faujasite-X zeolite
(State University of New York at Binghamton, 2006)
Toxic chemicals are abundant in the environment and their detection often requires very
costly and time consuming methods. Where such molecules are able to interact with the
transition metal cations, their characteristic ...
Sustainability of smallholder tea growing in Kenya
(2007)
Although tea was introduced in Kenya in 1903, Africans (natives) were barred from growing the crop until after independence in 1963 when the legislation was repealed. Africans started growing tea under the smallholder tea ...
Quality response of clonal black tea to nitrogen fertiliser, plucking interval and plucking standard
(John Wiley & Sons, Ltd., 2000)
Variations in the black tea quality of high‐yielding clone S15/10 in response to rates of NPKS 25:5:5:5 fertiliser of 200 and 400 kg N ha−1 year−1, plucking intervals of 7, 14 and 21 days and a selective plucking standard ...
