The term oleogustus was recently proposed to describe a sixth basic taste that could guide preference for fatty foods and dishes to an extent. However, experimental data on food preference based on fatty acid (FA) content is scarce. Our aim was to examine the role of FA profile of oils and preparations as well as FA sensory thresholds on the palatability of salty and sweet culinary preparations representative of traditional Spanish Mediterranean cooking. In this study, we used three oils with similar texture and odor profile but different in their FA composition (saturated, monounsaturated, and polyunsaturated) and compared subjects in regard to their FA detection threshold and perceived pleasantness and intensity. Our results indicate that whereas saturated FAs cannot be detected at physiological concentrations, individuals can be categorized as tasters and non-tasters, according to their sensory threshold to linoleic acid, which is negatively associated with perceived intensity (r =-.393, p < 0.001) but positively with palatability (r =.246, p = 0.018). These differences may be due to a possible response to a fat taste. This sixth taste, or oleogustus. would allow establishing differences in taste intensity/palatability considering the FA profile of the culinary preparations. Given that tasters can detect linoleic and oleic acid at lower concentrations than non-tasters, a greater amount of unsaturated FAs in culinary preparations could provoke an unpleasant experience. This finding could be relevant in the context of the culinary sector and to further our understanding of food preference and eating behavior.

脂肪烹饪制品的感知强度和适口性与单个脂肪酸检测阈值和用作成分的油的脂肪酸谱有关。

最近提出了术语奥古斯都(Orogustus)来描述第六种基本口味,可以在一定程度上指导人们对脂肪性食物和菜肴的偏爱。但是,关于基于脂肪酸(FA)含量的食物偏爱的实验数据很少。我们的目的是检验油和制剂的FA概况以及FA感官阈值对代表传统西班牙地中海烹饪的咸味和甜味烹饪制剂的适口性的作用。在这项研究中,我们使用了三种质地和气味相似但FA组成不同(饱和,单不饱和和多不饱和)的油,并比较了受试者的FA检测阈值和感觉到的愉悦度和强度。我们的结果表明,虽然在生理浓度下无法检测到饱和脂肪酸,根据其对亚油酸的感官阈值,将其分为味觉者和非品尝者,其与感知强度呈负相关(r =-。393,p <0.001),但与适口性呈正相关(r = .246,p = 0.018)。这些差异可能是由于对脂肪味道的可能反应。这是第六种味道,或oleogustus。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。根据他们对亚油酸的感觉阈值,与感知强度呈负相关(r =-。393,p <0.001),与适口性呈正相关(r = .246,p = 0.018)。这些差异可能是由于对脂肪味道的可能反应。这是第六种味道,或oleogustus。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。根据他们对亚油酸的感觉阈值,与感知强度呈负相关(r =-。393,p <0.001),与适口性呈正相关(r = .246,p = 0.018)。这些差异可能是由于对脂肪味道的可能反应。这是第六种味道,或oleogustus。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。p <0.001),但具有适口性(r = .246,p = 0.018)。这些差异可能是由于对脂肪味道的可能反应。这是第六种味道,或oleogustus。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。p <0.001),但具有适口性(r = .246,p = 0.018)。这些差异可能是由于对脂肪味道的可能反应。这是第六种味道,或oleogustus。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。考虑到烹饪制剂的FA谱,将可以建立口味强度/适口性的差异。鉴于品尝者能够以比非品尝者更低的浓度检测亚油酸和油酸,因此烹饪制剂中大量的不饱和脂肪酸可能会引起令人不快的体验。这一发现可能与烹饪领域有关,并有助于我们进一步了解食物偏爱和饮食行为。
