IMPACT OF FIBER-RICH FRACTION OF BANANA PEELS AS DIETARY FIBER SOURCE FOR PRODUCTION OF FIBER-ENRICHED COOKIES

Abstract

: Interest in dietary fiber as a functional ingredient is steadily increasing especially those that come from manufacturing waste. The present study aimed to investigate the effects of the addition of alcohol-insoluble fraction from banana peels (AIF-BP) at different particle sizes (PS)on cookies. AIF-BP was characterized by higher content of dietary fiber as well as its Water holding capacity (WHC) and Oil holding capacity (OHC) in respect of its PS. As portion of AIF-BP and PS increased farinograph parameters of water absorption (WA), dough development time (DDT) and dough weakening (DW) increased but had inverse effect on dough stability (DST). Fiber-enriched cookies (FEC) with lower spread ration and higher hardness were companied with the increment in AIF-BP at higher PS. All the sensory attributes of experimental and control FEC were acceptable.
