The main objective of this study was to evaluate the functionality of batters containing various starch and gum types during deep-fat frying of chicken nuggets. Additionally, this study provided a correlation between batter consistency and quality attributes of deep fat fried chicken nuggets. In the first part, the batter viscosity was correlated with fried product quality. Additionally, time dependency of batters was determined under constant shear rate. Pregelatinized starch, hydroxypropyl methylcellulose gum and xanthan gum were determined to have the highest apparent viscosity. Batter viscosity was found to be correlated with coating pickup. All batters were found to have thixotropic behavior except guar gum added batter, which was found to behave like a rheopectic fluid.In the second part, to evaluate the effects of various starch and gum types on quality attributes of deep fat fried chicken nuggets, coating pickup, texture, moisture content, oil content, oil uptake ratio (Ur), bulk volume, porosity, cooking yield, and color were measured for frying times of 3, 6, 9 and 12 minutes at 180°C. Amylomaize, corn, waxymaize, pregelatinized starches, and guar, xanthan, gum arabic, HPMC, MC gums were used in batter formulations, individually. A batter formulation with no starch or gum addition was used as control. As a result of the study, among different starch types used, pregelatinized starch was found to provide a product with the lowest oil content, the highest moisture content, coating pick up and volume. When all the hydrocolloids were compared, HPMC gum was found to be the most effective one on improving quality attributes of deep-fat fried chicken nuggets in terms of moisture content, oil content and cooking yield.

Effects of different batter formulations on quality of deep-fat fried chicken nuggets Doğan, Seyhan Firdevs; Şahin, Serpil; Department of Food Engineering (2004) The main objective of this study was to evaluate the effects of different flour and protein types on quality of deep-fat fried chicken nuggets. Additionally, the rheological properties of batters were studied and the batter viscosity was correlated with fried product quality. In the first part of the study, the effects of soy and rice flour (5%) addition to the batter formulation on product quality were studied. Coating pick-up of batters, and moisture content, oil content, texture, color, volume, porosity,...
Effects of different batter formulations on quality of deep-fat fried carrot slices Akdeniz, Neslihan; Şahin, Serpil; Department of Food Engineering (2004) The main objective of the study was to evaluate the effects of starch and gum types on product quality of deep-fat fried carrot slices. It was also aimed to evaluate the applicability of image processing for determination of oil uptake. In the first part of the study, carrot slices were dipped into batters containing three different concentrations of dextrin or pre-gelatinized tapioca starch and fried for 2, 3, and 4 minutes at 170±2 oC. Coating pick-up of batter formulations and moisture content, oil conte...
Effects of different batter formulations on physical and chemical properties of microwave and conventionally fried chicken fingers Barutçu Mazı, Işıl; Şahin, Serpil; Department of Food Engineering (2009) The main objective of this study was to determine the effects of batters containing various flour types and frying methods on physical and chemical properties of chicken fingers. To determine the effects of different flour types, 30 % of the corn and wheat flour mix in control batter was replaced with chickpea, rice or soy flours. Frying was performed in microwave oven at 365 W (70 %) power level and at 1801°C for different times. Samples were also fried in a conventional fryer at 1801°C for comparison. T...
Functionality of batters containing different starch types for deep-fat frying of chicken nuggets Altunakar, B; Şahin, Serpil; Şümnü, Servet Gülüm (Springer Science and Business Media LLC, 2004-03-01) The effect of various starch types (amylomaize, corn, waxymaize, pregelatinized tapioca) on quality attributes (texture, moisture content, oil content, color, coating pick up, cooking yield, volume and porosity) of deep-fat fried chicken nuggets were studied. Chicken samples, 0.04 m in diameter and 0.015 m in thickness, taken from the breast portion, were coated with batters composed of a 3:5 solid to water ratio by immersion. The solid content of batter formulations contained equal amounts of corn and whea...
Functionality of batters containing different gums for deep-fat frying of carrot slices Akdeniz, N; Şahin, Serpil; Şümnü, Servet Gülüm (Elsevier BV, 2006-08-01) The effects of addition of different hydrocolloids such as hydroxypropyl methylcellulose (HPMC), guar gum, xanthan gum and guar-xanthan gum combination to the batter formulations on quality of deep-fat fried carrot slices were evaluated. Coating pick up of batter formulations and moisture content, oil content, texture, porosity and color of samples were determined during frying at 170 degrees C for 2, 3 and 4 min. Gums were effective in controlling moisture loss and oil uptake, producing crisp and porous pr...
