Abstract Tea is one of the most popular beverages having a great beneficial effect on human health. Biol Pharm Bull ; Mardiyaningsih A, Aini R. Coffee bean containing caffeine, phenolic, trigonelline, and chlorogenic acid is reported to have antimicrobial activity. Widyotomo S, Sri M. However, tea also contains an undesirable compound called caffeine.

Bioactive Micronutrient in coffee: Taguri T, Kouno TA. Polyphenolic chemistry of tea and coffee: Influence of apigenin on gtf gene expression in Streptococcus mutans UA A kkafein diffusion equation coupled with a macroscopic mass transfer equation for solvent was developed and then solved analytically.

Some researches in Dentistry Faculty show that many plants are efficacious for oral health. In conclusion, Robusta and Arabica coffee extracts have inhibitory effects on L. Efek Antibakteri ekstrak daun mimba Azadirachta indica A. Anti microbial investigation of Suaeda baccata chenopodiaceae. This research was focused on production of low caffeine content tea using extraction ekstrakso ethyl acetate as solvent.


Pengembangan model matematik proses dekafeinasi biji kopi robusta dalam reaktor kolom tunggal

Pengembangan model matematik proses dekafeinasi biji kopi robusta dalam reaktor kolom tunggal Development of mathematical model for robusta coffee decaffeination process in a single column reactor. J Pharmaciana ; 4 2: Jurnal e-gigi ; 1 1: Afterwards, measurements ekstrakei observations were conducted on inhibition zone area.

For coffee consumers who have high tolerance for caffeine, coffee may warm up and refresh their bodies. J Microbiology ; 50 2: Juss ekstfaksi bakteri vibrio alganoliticus secara in vitro. Coffee decaffeination was processed using vertical single column reactor.

The method used was well diffusion method using seven samples for each treatment group. Influence of Apigenin on gtf ekstraksu expression in Streptococcus mutans UA Jurnal Kedokteran Brawijaya, ; 26 4: Pengembangan potensi ekstrak daun pandan Pandanus amaryllifolius Roxb sebagai agen antibakteri.

This compound can cause some undesirable reactions such as insomnia, nervous, delirium, tachycardia, extra systole, respiratory increase, tremor, and dieresis. Can coffee prevent caries?.


Antibacterial ability of arabica Coffea arabica and robusta Coffea canephora coffee extract on Lactobacillus acidophilus. This research aimed to determine the differences in the inhibition of Arabica and Robusta coffee extract to L. Some features of this site may not work without it.


User Username Password Remember me. The specific objectives of this research were to study process characteristic of Robusta coffee decaffeination in single column reactor using acetic acid as solvent, to develop mathematical model for predicting decaffeination time with leaching method, and to optimize process decaffeination of robusta coffee using developed model.

This research was an laboratory experimental research. Temperature T and concentration c of solvents were both variables analysed in decaffeination process. Pengalaman karies gigi serta pola makan dan minum pada anak sekolah dasar di desa Kiawa Kecamatan Kawangkoan Utara. Identification of oral strains of Lactobacillus species isolated from Mexican and french children.

Robusta coffee bean extract, nevertheless, has better inhibitory effects than Arabica coffee bean extract. Journal of Agricultural and Food Chemistry ; Journal of Dentistry and Oral Hygiene ; 1 1: The data resulted was processed using Response Surface Methodology to obtain mathematical model and optimum operating condition.
