REFORMULATING TORTILLAS WITH ZERO-TRANS CRYSTALLIZED VEGETABLE FAT PRODUCED FROM PALM STEARIN AND HIGH OLEIC SAFFLOWER OIL BLEND

Abstract

The effects of zero-trans crystallized vegetable fatproduced from palm stearin and high oleic safflower oil (PS/HOSO, 65:35) blend on the texture and sensory properties of wheat flour tortillas (WFT) were studied. WFT were prepared with a (PS/HOSO, 65:35) crystallized blend, instant flour (hydrogenated commercial shortening/emulsifier blend) and hydrogenated commercial shortening (HCS). Firmness, rollability, and moisture loss were measured at different storage times (2, 24, 48, and 72 h). The blend (PS/HOSO, 65:35) had high proportion of palmitic (49.03%) and oleic acids (36.78%), without trans fatty acids (TFA), with the presence of the polymorphic form β. Tortillas manufacturing with (PS/ HOSO, 65:35) blend showed lower firmness values than tortillas elaborated with instant flour, and HCS. The blend (PS/ HOSO, 65:35) affected positively the quality of tortilla and sensory properties; showed this zero trans crystallized fat can be a potential alternative to HCS to reduce trans fats in cereal-based foods.
