Identification of oral strains of Lactobacillus species isolated from Mexican ekstrwksi french children. Can coffee prevent caries?. Abstract Consumers drink coffee not as nutrition source, but as refreshment drink. In order to reduce negative effect of caffeine, general method have been applied for reducing caffeine content by using solvent extraction and supercritical extraction with CO2. Mathematical model validation was checked by comparing prediction time t-predict versus observation time t-obsr.

Antibacterial activity of coffee extracts and selected cofee chemichal compounds against Enterobacteria. However high caffeine content in coffee beans may cause health problems to consumers who are susceptible to caffeine. Anti microbial investigation of Suaeda baccata chenopodiaceae. Pengembangan potensi ekstrak daun pandan Pandanus amaryllifolius Roxb sebagai agen antibakteri.
