In the present work, pasta enriched in different formulations by black mulberry extract in order to inhibit enzymes related to starch hydrolyzation. Total phenol content (TPC), antioxidant activity and anthocyanin components of ethanol/water black mulberry extract were investigated. TPC of the black mulberry extract was found 65.61 ± 0.07 mg GAE/g. Black mulberry extract could scavenge the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals more effectively than tertiary butylhydroquinone (TBHQ) also vitamin C due to its detected polyphenolic compounds (cyanidin-3-glucoside, cyanidin-3-rutinoside, and cyanidin-3-xyloside). TheICvalue of the black mulberry extract was obtained 8.31 μg/mL while it was measured 59.62 and 62.64 μg/mL for TBHQ and vitamin C, respectively. The pasta-enriched with freeze-dried black mulberry extract showed effective inhibition against applied α-amylases (α-amylase from porcine pancreas, Bacillus sp, and human saliva) and α-glucosidase originated from Saccharomyces cerevisiae. The ICvalues of tested enzymes exhibited that black mulberry effectively act as an inhibitory agent comparing with acarbose because of its antioxidant activity. Results revealed that starch hydrolysis index (HI) and predicted glycemic index (GI) of cooked pasta-enriched with various concentration levels of black mulberry extract were significantly decreased especially when 1.5% of the extract was incorporated. In addition, The ICvalue of the black mulberry extract obtained from cooked pasta was increased againstα-amylase and α-glucosidase. The results obviously presented that diabetes mellitus type 2 could be resolved by enrichment of polyphenolic compounds into the pasta.
