Abstract

Green coffee extract, GCE (Coffee canephora) was used at 1.0, 1.5 and 2.0% levels for making bioactive rich bread. The processed GCE from the green coffee beans had 21.42% gallic acid equivalents (GAE) total polyphenols (TPP), 37.28% chlorogenic acid (CGA) and 92.73% radical scavenging activity (RSA), at 100 ppm concentration of GCE and caffeine content (1.75%). Rheological, physico-sensory and antioxidant properties of GCE incorporated breads were analysed and compared with control bread. The results revealed not much significant change in the rheological characteristics of dough up to 1.5% level; an increase in bread volume; greenness of bread crumb and mostly unchanged textural characteristics of the bread with increased addition of GCE from 0 to 2.0%. Sensory evaluation showed that maximum level of incorporation of GCE without adverse effect on the overall quality of bread (especially taste) was at 1.5% level. The contents of TPP, RSA and CGA increased by 12, 6 and 42 times when compared to control bread and had the highest amount of 4–5 caffeoylquinic acid.
