Sencha is a type of decoct Japanese green tea, most popular tea in Japan, made from the dried tea leaves without grinding the tea leaves. It volatile compounds could be used as markers for the overall quality evaluation of all green teas, according to the study of "Predication of Japanese green tea (Sen-cha) ranking by volatile profiling using gas chromatography mass spectrometry and multivariate analysis" by Jumtee K, Komura H, Bamba T, Fukusaki E..
Green Sencha Health Benefits
13. Antimicrobial activities
a. In the investigation of Antimicrobial activities of green of the study of "Antimicrobial activities of tea catechins and theaflavins and tea extracts against Bacillus cereus" by Friedman M, Henika PR, Levin CE, Mandrell RE, Kozukue N.[13a], researchers found that flavonoids in green tea has exerted its ability in protective effects against Bacillus cereus.
b. In the evaluation of green tea extracts (GTEs) and their effects in Antimicrobial activities of the study of "Antimicrobial activities of tapioca starch/decolorized hsian-tsao leaf gum coatings containing green tea extracts in fruit-based salads, romaine hearts and pork slices" by Chiu PE, Lai LS., reserachers found that coatings containing GTEs could successfully reduce the aerobic counting and growth of yeasts/molds by 1 to 2 log cycles in fruit-based salads.
c. In the observation of green tea and rosemary leaf powders on the growth of microorganisms of the study of "Inhibitory effect of commercial green tea and rosemary leaf powders on the growth of foodborne pathogens in laboratory media and oriental-style rice cakes' by Lee SY, Gwon SY, Kim SJ, Moon BK.[13c], researchers indicated that 1 or 3% green tea or rosemary to rice cakes did not significantly reduce total aerobic counts; however, levels of B. cereus and S. aureus were significantly reduced in rice cakes stored for 3 days at room temperature (22 degrees C) and that suggested the use of natural plant materials such as green tea and rosemary could improve the microbial quality of foods in addition to their functional properties.
d. In the investigation of antibacterial and anticarcinogenic effects of tea catechins of the study of "Application of a functional mathematical index for antibacterial and anticarcinogenic effects of tea catechins" by Finotti E, Bersani E, Friedman M.[13d], researchers wrote that catechins of a large number of teas have exerted their dual beneficial effects: antimicrobial activities against a foodborne pathogen and inhibition of human cancer cell lines.
