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.
本研究的目的是开发一种用于油炸肉类产品的新型烹饪方法,以提高其营养价值,并提供更好的口感和质地。我们在辐射热烘烤过程中使用来自每种肉类来源的脂肪(用其自身脂肪交替烘烤:AROF),而不进行深度油炸(DFF),首先在没有任何气流的情况下进行,随后暴露于气流中。然后,我们将这些烤鸡肉样品与在三种类型的脂肪中进行深度油炸的裹面包屑炸鸡样品进行比较:大豆油(SB)、部分氢化大豆油(PSB)和猪油。AROF鸡肉样品的皮和瘦肉部分的最终脂肪含量均低于DFF组的一半。与DFF样品相比,AROF样品中的总反式脂肪酸(TFA)含量显著更低。除了用猪油油炸的样品胆固醇水平显著更高外,各测试组样品的胆固醇水平没有显示出任何显著差异。此外,感官评价结果表明,AROF样品的酥脆口感与DFF样品没有显著差异(P<0.05);AROF样品在特征性油炸风味和总体可接受性方面得分更高(P<0.05)。本研究显示了通过AROF制备的产品的潜在价值,其可以成功替代用于鸡肉和其他肉类产品的DFF方法并提高其营养价值。
