    Abstract:
    The aims of the work were to determine the chemical, techno-functional and antioxidant properties of native Mexican apple pomace powder (MAPP) obtained from cider industry. The proximate composition and the total, insoluble and soluble dietary fibre content were determined, as well as the water holding (WHC), oil holding (OHC), swelling (SWC) capacities and the polyphenolic profile. For antioxidant activity, three different test systems were used (DPPH, FIC and FRAP). The total, insoluble and soluble dietary fiber content of MAPP was 70.91, 48.43 and 22.48 g/100 g, respectively. MAPP had a WHC, OHC and SWC of 4.2 g water/g sample, 1.69 g oil/g sample and 3.2 mL/g sample, respectively. Polyphenolic profile showed 10 flavonoid compounds identified mainly quercetin glycosides. MAPP showed good antioxidant activity with high correlation between total phenolic compounds and antioxidant capacity. The results obtained showed that MAPP could be considered a good source of bioactive compounds with significant antioxidant activity.
