| Summary: | (degraded for 60 hr) showed a different temperature profile (ESEM) pictures demonstrated that the starch/protein matrix (OBH), raw, and freezing OBH at -12 C for 24 hours (FT). 190'C and quality of the final products were analyzed. The and the size of the pores throughout the chip were the most baked in a 3-tiered gas-fired oven at 343'C, 190C, and 190C baked in an air forced oven at 190C for 3.5 min (OBL), oven- content, moisture content, and fracturability. Tortillas were discarded after 25 hours of use when the amount of total during frying as compared with the fresh oil. The levels of fatty acid contents, total polar materials, convective heat for the top, middle, and bottom,, respectively, for 71 sec frying suggested that the soybean oil should have been important factors affecting the force needed to break through initial moisture content of the tortilla affected the final oil content of the chip, significantly. The pre-frying oil degradation did not pose any significant effects on oil polar materials reached 27%. The abused soybean oil prepared under different pre-frying conditions, i.e., oven- Refined soybean oils were degraded at 190C for 60 hours. It surface tension. The off-flavor and foaming developed during the tortilla chips. These tortillas were fried in fresh soybean oil for 60 sec at tortilla chips. Environmental scanning electron microscopy transfer coefficient, color, specific gravity, viscosity, and treatments affected the final oil and moisture contents of was observed that degradation time correlated well with free |
