Teores de trigonelina, ácido 5-cafeoilquínico, cafeína e melanoidinas em cafés solúveis comerciais brasileiros

Abstract: Recebido em 4/6/12; aceito em 14/11/12; publicado na web em 18/2/13 TRIGONELLINE, 5-CAFFEOYLQUINIC ACID, CAFEINE AND MELANOIDINS LEVELS IN COMMERCIAL BRAZILIAN INSTANT COFFEES. Commercial Brazilian regular and decaffeinated instant coffees (33 brands) were studied. The levels ranged from 0.47 to 2.15 g 100 g -1 for trigonelline, 0.38 to 2.66 g 100 g -1 for 5-caffeoylquinic acid (5-CQA), 0.24 to 4.08 g 100 g -1 for caffeine, and 0.253 to 0.476 (420 nm) for melanoidins. Variations in bioactive compound levels am… Show more

“…In Brazil, the most common roasts are medium and moderate-dark [10], which define Brazilian coffee to be extremely bitter and dark, with a "smoked" taste and a reduced aroma [11]. Therefore, marketing a blend rich in green coffee extract requires knowledge about how to introduce a product based on the interests, preferences and attitudes of Brazilian consumers (the second largest consumer market).…”

“…Considering the current concern about the health benefits associated with the consumption of coffee products, this study presents data on the antioxidant activity (AA) of Brazilian commercial soluble coffees considering radical scavenging activity (via the ABTS method) and reducing capacity (via the Folin-Ciocalteu method). The results were also correlated with the main bioactive compounds in the samples, which were analyzed in a preliminary study [28].…”
