Changes in thearubigin fractions and theaflavin levels due to variations in processing conditions and their influence on black tea liquor brightness and total colour
(Elsevier, 2004-03-30)
Increase in coarser plucking standards significantly (P< 0.05) depressed levels of theaflavin
(TF; μmol/g), total colour and brightness (spectrophotometer) of black tea. But total
thearubigins (TR) TRSI, TRSII and ...
Flavanol composition and caffeine content of green leaf as quality potential indicators of Kenyan black teas
(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 ...
Antinociceptive and antiplasmodial activities of cassane furanoditerpenes from Caesalpinia volkensii H. root bark
(Elsevier, 2012-01-01)
The chloroform and ethyl acetate extract (100mg/kg) of Caesalpinia volkensii H. exhibited
significant (P≤ 0.05) antinociceptive activities using hot plate and writhing tests in mice
while the later showed antiplasmodial ...
Influence of region of production on relative clonal plain tea quality parameters in Kenya
(Elsevier, 2010-04-01)
Tea is grown in diverse regions with varying climates. Growers seek high-yielding and
superior quality cultivars to improve profitability of the enterprise. A superior quality genotype
in one location is assumed to ...
Clonal plain black tea quality parameters responses of hard physical withered leaf to rehydration and fermentation durations
(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. ...
Effects of nitrogenous fertilizer rates, plucking intervals and location of production on the micronutrient levels of clonal black tea.
(International Society of Tea Science, 2014)
Micronutrients are important to both animal and plant life. In plants, the levels can
vary widely due to biotic and abiotic factors. Tea is widely grown and its beverages are
claimed to be the most widely consumed ...
Response of Plain Black Tea Parameters, Individual Theaflavins and Yields Due to Location of Production and Clones within Lake Victoria Basin
(International Society of Tea Science, 2019)
Tea (Camellia sinensis) is a major cash crop and leading foreign exchange earner, contributing to poverty alleviation by providing employment and livelihood to many stakeholders in the producing countries. Production has ...
Effects of genotype, environment and management on yields and quality of black tea Authors
(Springer Netherlands, 2011)
The tea beverages processed from the young tender shoots of Camellia sinensis
(L.) O. Kuntze, are claimed to be the most widely consumed fluids after water. The tea plant
originates from the point of confluence of ...
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 ...
