Tortilla chips were made with extruded flours[0.1% Ca(OH)2; 0.9% C6H10O6Ca; without calcium] and nixtamalized flours [1% Ca(OH)2; 2.95% C6H10O6Ca] using the fryingprocess. Total anthocyanin, total phenolics content, antioxidant activity, color, texture, and oil content were determined. Thecolor of tortilla chips from extruded flours (TCEF) showed high values of the parametersa*andb*indicating a reduction inthe blue color. These color parameters were significantly different from those observed in tortilla chips from nixtamalized flours(TCNF), which tended to be more blue. The TCEF retained 15% anthocyanins, 34% phenolics, and 54% antioxidant activity.Pearson’s correlation analysis indicated that anthocyanins and phenolics correlated significantly with antioxidant activity andcolor. TCEF with both calcium sources showed higher fracturability compared with that of TCNF. Oil absorption showed anopposite effect, with lower oil content in TCEF. Nixtamalization and extrusion with C6H10O6Ca resulted in flours and TC highin anthocyanins and antioxidant activity, representing an alternative production process for corn snack high in antioxidants. 2014 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395940094021 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.1 Vol.34 |
