The development of a novel cooking method (alternate roasting with its own fat) for chicken to improve nutritional value

The goal of this study was to develop a novel cooking method for fried meat products, to improve their nutritional value, and to provide superior taste and texture. We used the fat derived from each individual meat source during radiant heat roasting (alternate roasting with its own fat: AROF) without deep-fat frying (DFF), first without any air flow and subsequently with an exposure to air flow. We then compared these roasted chicken samples to breaded fried chicken samples that were deep-fat fried in 3 types of fat: soybean oil (SB), partially hydrogenated soybean oil (PSB), and lard. The final fat contents of both the skin and lean parts of the AROF samples of chicken were less than half of those of the DFF groups. The total trans-fatty acids (TFA) contents were significantly lower in the AROF samples compared to the DFF samples. The cholesterol levels of the samples did not show any significant differences among the tested groups, except for the sample fried in lard, which was significantly higher. Moreover, the sensory evaluation results showed that the crispy texture of the AROF samples was not significantly different from that of the DFF samples (P < 0.05); the AROF samples had higher scores for the characteristic fried flavor and for overall acceptability (P < 0.05). This study shows the potential value of products prepared by AROF, which can successfully replace DFF methods used for chicken and other meat products and improve their nutritional value.
