Biodegradability Simulation of Coffee Wastewater Using Instant Coffee

Angioedema from instant coffee.

Acute allergic angioedema is an abrupt-onset, unpredictable inflammatory reaction of the skin and mucous membranes. Without treatment, the condition may resolve within hours; however, when swallowing or breathing is affected, emergent medical attention is required. We report an atypical presentation of this condition, with a unique dietary cause. A 50-year-old man with no relevant medical histo...

Genotoxicity of instant coffee: possible involvement of phenolic compounds.

Instant coffee exhibits direct genotoxic activity in the tester strains TA 98, 100, 102, 104 and YG 1024. In the Ames tester strain TA 100, the presence of S9 mix, S100 mix, S9 mix without cofactors led to a significant decrease of the genotoxicity observed. The decrease observed in the presence of S9 mix seems to be highly correlated with the catalase content of S9 mix. The genotoxicity of ins...

Comparison of Fluoride Content in Caffeinated, Decaffeinated and Instant Coffee

A previous study has reported the mean fluoride (F) level of decaffeinated tea infusions, 3.19 ppm, is significantly (P<0.01) higher than those of caffeinated tea infusions, 1.74 ppm. The present study is designed to determine F concentrations of coffees available in the Houston area and to determine if different types of coffee may vary in their F content. Forty different brands and types of c...
