Epidemiological studies have found a positive association between coffee consumption and a lower risk of cardiovascular disorders, some cancers, diabetes, Parkinson and Alzheimer disease. Coffee consumption, however, has also been linked to an increased risk of developing some types of cancer, including bladder cancer in adults and leukemia in children of mothers who drink coffee during pregnan...

Background: Coffee is one of the most widely consumed beverages in the world and it has been demonstrated that it has important therapeutic activities not only because of its caffeine content but also owing to the presence of other biologically active small molecules such as chlorogenic acid, trigonelline and cyclopentadiones. However, chlorogenic acid is degraded into catechol, pyrogallol and ...

The use of plant extract is generating interest of researchers toward cost effective and eco-friendly green synthesis of nanoparticles. In the present work, Cupric oxide nanoparticles were synthesized using coffee powder extracts by the sol-gel method at different calcination temperatures. The synthesized nanoparticles were characterized by X-ray diffraction, scanning electron microscopy , ultr...

A Wireless Sensor Networks is a network formed with sensors that have characteristics to sensor an area to extract a specific metric, depending of the application. We would like to analyse the feasibility to use sensors in a coffee crop. In this work we are evaluating routing protocols using real dimensions and characteristics of a coffee crop. We evaluate, through simulation, AODV, DSDV and AO...

Coffee is quite popular of the leisure drink, and the ingredients of coffee include caffeine, aroma, protein, tannic acid and fat et al. The references show a small amount of caffeine can stimulate the brain and enhance memory, if caffeine is over the amount that heart, high blood pressure, kidney and coronary artery would be caused a negative impact. In this paper, we use the special ultrasoun...

Caffeine is a secondary metabolite compound derived from the alkaloid group with its characteristic bitter taste. This study aims to analyze water content, ash coffee extract and caffeine test using High-Performance Liquid Chromatography (HPLC) method on ground six different types of coffee. The used for analysis refers SNI 01-3542-2004. In content test, 2983:2014 concerning instant was extract...
