Yuksel, Ferhat; Kaya, Şemsettin
The objective of this study was to develop wheat chips fortified with purple wheat flour (PWF) and to evaluate the effects of PWF incorporation, frying temperature, and frying time on starch fractions, bioactive properties, antioxidant activity, and acrylamide formation. Response Surface Methodology was applied to assess the effects of PWF concentration (0%–100%), frying temperature (170–190 °C), and frying time (40–60 s) on the quality and functional properties of wheat chips. Resistant starch ranged from 0.51 to 0.80 g/100 g and increased slightly with higher PWF levels; this increase was found to be statistically significant. Acrylamide content was found to be a statistically significant parameter (p < .05), showing a decreasing trend from 1,362.68 to 1,082.76 μg/kg with increasing levels of PWF incorporation. Total phenolic, flavonoid, anthocyanin, and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl (DPPH), free radical scavenging capacity (ABTS)) significantly improved with PWF enrichment, whereas ferric reducing antioxidant power showed no notable change. These findings indicate that PWF can be effectively incorporated into deep-fried wheat chips, enhancing their functional and bioactive properties while reducing acrylamide formation.

Yuksel, F.
In this study, traditional homemade noodles were enriched with raw flaxseed and some nutritional properties such as resistant starch (RS), total starch, total dietary fibre (TDF), estimated glycaemic index (eGI) and major mineral composition of final products were investigated. Flaxseed was supplemented into the noodle mixture at three different concentrations (10, 15 and 20 g/100 g). RS content of the samples was in the range of 0.61-2.14 g/100 g and the highest RS was found for the sample having 10% flaxseed. Maximum TDF value was determined to be 8.28% for the noodle sample enriched with 20% of flaxseed while that of control was 1.68%. Estimated eGI of the samples was not significantly affected by the flaxseed fortification while mineral composition of noodle samples was significantly affected by the flaxseed addition (P < 0.05). The major mineral compounds present in the samples were sodium, potassium, magnesium and phosphorus. It could be concluded that the noodle enriched with 10% of flaxseed would be a healthier alternative product for consumption.
