Biochemical attributes of tea flowers (Camellia sinensis) at different developmental stages in the Kangra region of India

Physiological and biochemical attributes were studied in different developmental stages from unopened bud (stage 1) to full bloom (stage 5) of flowers of tea (Camellia sinensis). The proteins recorded higher levels in stages 1 and 2 and decreased thereafter with development of flowers. Like the tea shoots, flavan-3-ol EGCG and EC were present in highest and lowest amounts, respectively in all stages of flower development. The highest content of flavan-3-ols EGC and EGCG were found in stage 3. The highest proanthocyanidins content was observed in stage 2 and decreased to a minimum at full bloom stage. Polyphenol oxidase, β-glucosidase activities were found to increase from bud to stage 3 where petals started to split and slightly decreased thereafter. Glycosidic bound volatile compounds viz. Linalool oxide cis (3.11%), linalool (22.73%), geraniol (2.69%), 2,4-di-tert-butylphenol (9.71%), methyl palmitate (2.78%), methyl linoleate (2.74%), methyl salicylate (2.62%), α-terpineol (0.33), beta-ionone (1.24%) and nerolidol (0.8%) were present in higher amounts at stage 3 of flower development. The volatile flavour components recorded higher values at stage 3 of flower development with higher contents of linalool, geraniol, linalool oxides, acetophenone, pentadienal, benzaldehyde and hexanoic acid. Antioxidant activity of tea flowers also increased from bud to reach the maximum at stage 3 and decreased to a minimum in the full bloom stage.     

Effect of selenium on green tea preservation quality and amino acid composition of tea protein

Summary

To increase the selenium content of tea produced in areas of China poor in selenium, sodium selenite was added to tea garden soil or was sprayed onto tea leaves. Effects of selenium on green tea quality and the amino acid composition of tea protein were studied. Selenium-enriched green tea and poor selenium green tea were extracted with hot water (100?C)at a 1:50 ratio (w/v). The tea leaf extracts were stored at 30?C for 12.h, the colour changes of selenium-enrichedgreen tea extract were more stable than with poor selenium green tea extract. The teas were packaged in polypropylene plastic bags and then stored at room temperature for 90.d. The reduced ratio of vitamin C in selenium-enriched green tea was 21% compared with poor selenium content green tea at 52%. These results demonstrated that selenium-enriched green tea produced a more desirable quality than poor selenium green tea. The total amino acid amounts, essential amino acid, methionine acid and cystine acid content of different selenium-enriched green tea protein were increased by 8.3%–14.8%, 8.8%–14.8%, 6.0%–8.7% and 39%–96%, respectively, compared with the low selenium green tea. Green tea qualitywas raised by selenium treatment.
