Abstract

In this study, the effects of ultrasound pretreatment applied at different frequencies (20, 40, and 60 kHz) and durations (10, 20, and 30 min) were investigated to reduce oil uptake and improve potato chip quality. Following deep-fat frying (160 °C), the oil content, shrinkage, color, and textural attributes (hardness, deformation energy, and crispness) of the samples were evaluated. It was determined to increase the treatment time at 20 kHz negatively affected the oil content, area change, and hardness properties. In the 40 kHz, the lowest oil uptake and area change values were obtained at the 20 minutes condition (P<0.05), whereas at the 60 kHz for 20 minutes resulted in the lowest oil uptake (P<0.05). Furthermore, it was observed that ultrasound treatment in 60 kHz minimized shrinkage and limited excessive thermal browning. Results indicate that high-frequency ultrasound applications are an effective pretreatment alternative for restricting oil content while preserving structural quality.

Özet

Bu çalışmada patates cipsi üretiminde yağ emilimini azaltmak ve ürün kalitesini iyileştirmek amacıyla farklı frekans (20, 40 ve 60 kHz) ve sürelerde (10, 20 ve 30 dk) uygulanan ultrases ön işleminin etkileri incelenmiştir. Derin yağda kızartma (160 °C) sonrasında örneklerin yağ içeriği, büzülme, renk ve dokusal (sertlik, deformasyon enerjisi ve gevreklik) özellikleri değerlendirilmiştir. 20 kHz’de işlem süresinin artmasıyla yağ içeriği, alan değişimi ve sertlik özelliklerinin olumsuz yönde etkilendiği tespit edilmiştir. 40 kHz uygulamasında ise 20 dk. işlem koşulunda en düşük yağ emilimi ve alan değişimi değerleri elde edilmiştir (P<0.05), 60 kHz frekansında 20 dk. uygulanan ön işlemin ise en düşük yağ emilimini sağladığı belirlenmiştir (P<0.05). Ayrıca 60 kHz uygulamalarında ultrases işleminin büzülmeyi minimize ettiği ve aşırı termal esmerleşmeyi sınırlandırdığı tespit edilmiştir. Sonuçlar yüksek frekanslı ultrases uygulamasının yapısal kaliteyi koruyarak yağ içeriğini sınırlandıran etkin bir ön işlem alternatifi olduğunu göstermektedir.
