Processing effect on the bioactive compounds content of Mexican jalapeño peppers for chipotle (Capsicum annum L.)

Abstract

The objective of this work was to evaluate the antioxidant capacity and bioactive compounds content in two Jalapeño pepper varieties, both fresh and smoked-dehydrated (chipotle) and in commercial chipotle pepper sauces. The antioxidant capacity, capsaicin content, carotenoids and total phenols were evaluated. The smoked-dehydrated process had an effect on all the variables analysed (P?0.05). The chipotle pepper presented higher antioxidant activity (112.33 µmol ET/g) and content of bioactive compounds than fresh pepper and commercial sauces. In fresh pepper, the 100-Grande variety had higher antioxidant capacity (71.92 µmol ET/g) than Apache (48.31 µmol ET/g), while no effect on any of the analysed variables was reported in chipotle peppers. It is concluded that the smoked-dehydrated process of jalapeño pepper affects quality in a positive way, significantly increasing the nutritional and functional value derived from an increase in the bioactive compounds content and the antioxidant activity of chipotle peppers due to this process.
