They can be easily foundas coffee processing by-product in coffee roasting plants and are presently used as fuel (1-2).However, because its composition its potential as source of functional food ingredients hasbeen also proposed (3-6). Strong antioxidant properties and prebiotic character have beensome of the beneficial effects associated to SK. It is believed that the antioxidant propertiesof SK are a consequence of its high contents in melanoidins generated by Maillard reactionduring roasting and free phenol surviving the thermal processes. Because it's powerfulantioxidant capacity extracts of this by-product may be used for other applications such ascosmetic. Antiaging cosmetics and preparations for antiaging nutricosmetic treatrnents arenowadays very popular. Therefore, the application of a coffee by-product to achieve this goalmay allow its green recycled in an economical rentable manner for the producer.Preclinical data regarding to the antiaging properties of SK extracts employing as animalmodel Caenorhabditis elegans were collected during the present study. C. elgans lifeexpectancy is very short, between two and three weeks, being a use fui model of acceleratedageing. SK extracts were produced according to procedure patented by the Spanish researchteam (5). Worms of 3 days of age were feed with standard diet and diet supplemented with theSK extracts. Accelerated aging was induced by treating the worms every day for 45s with UV.Nematodes feed with a doses of lmg/ml of SK extract showed a very significant longerlongevity than those feed with a standard diet. The effect was similar to those observed forvitamin C and chlorogenic acid in doses of 0.1 ug/ml. Our results support the antiagingproperties ofthe patented extract and its great potential for nutricosmetic.1. Saenger, M et al. (2001). Renewable Energy, 23,103-121.2. Menéndez, 1. A et al. (2007).
