Investigations of some quality parameters and mathematical modeling of dried functional chips

Abstract

In this study, the production of green olive, chickpea and haricot bean added potato chips was investigated in order to produce a functional snack food appealing to consumers from all age groups. Chips were produced by hot air drying (75–85 °C), vacuum drying (75–85 °C, 250 mbar), and microwave drying (90 W and 180 W). The effective diffusion coefficient of chips was calculated as between 4.25 × 10−9- 4.38 × 10−8. When the drying behavior of samples was examined; vacuum drying, convectional drying and microwave drying fitted in Page and Modified Page models. Total acidity, pH, salt, protein, total phenolics and antioxidant activity analyses were conducted in chips and chips doughs. In olive added chips, the highest total phenolic content was determined in the sample produced by vacuum drying method at 85 °C. Moreover, for chickpea-olive added chips, the highest total phenolic content and antioxidant activity were determined in microwave dried (180 W) samples. In haricot bean and olive added chips, antioxidant activity showed differences according to drying methods. Chickpea and haricot bean addition into chips doughs were increased the protein content in dried samples.
