Antioxidant product derived from coffee residues CSIC has developed a procedure for the extraction of antioxidant compounds from coffee silverskin, a residue of roasted coffee beans. The method involves an extraction step with water and the extracts contain high amounts of bioactive compounds such as chlorogenic acid and caffeine, with applications in cosmetics, food and health. Industrial partners interested in the development and commercialisation of this technology, are An offer for Patent Licensing Valorisation of a by-product of the coffee industry
The procedure consists on the extraction of the coffee silverskin (the
only by-product of coffee roasting) without prior milling, by using
subcritical water at moderate temperature (50ºC or higher) and high
pressure (1500 psi), although unpressurized water at 100ºC can be used too. Under these conditions, extracts with high antioxidant properties
are obtained in 10-20 min, with antioxidant activity depending on the extraction conditions: 0.85 – 3,7 g of equivalents of chlorogenic acid and 150 – 450 mg of caffeine, both per 100 mg of silverskin, when extracted
with only hot water or under subcritical conditions, respectively. The extracts, following lyophilisation, are stable at room temperature
for more than 6 months, making them highly suitable for its use as
antioxidants. Moreover, they keep its antioxidant activity after in vitro
gastrointestinal digestion, which broadens its potential applications as
functional ingredients. Finally, the extract can be used directly as a cosmetics ingredient, facilitating a pH closer to than of the skin.

Seasonal Influenza – What It Is and How Kansans Can Protect Themselves What is influenza? Influenza (flu) is a viral infection of the nose, throat, bronchial tubes and lungs. There are two main types of virus - A and B. Each type includes many different strains, which tend to change each year. When does influenza occur? Influenza occurs most often in the winter months.
