概括
挑食者不喜欢食物的质感是因为主观的评价,而不是触觉敏感度较低. 喜欢纹理,而不是触觉值,与挑性饮食和食物享受有关.
科学领域:
- 感官科学 感官科学
- 心理学 心理学 心理学
- 营养 营养 营养 营养 营养
背景情况:
- 食物质地对食物的接受有很大影响,特别是对于挑食者来说,他们可能会根据质地拒绝食物.
- 以前的研究表明,挑食者对触觉刺激的敏感性增加了,这可能导致对纹理的厌恶.
- 存在两个假设:挑食者具有较低的触觉检测值或对纹理的不同主观评估.
研究的目的:
- 为了研究触觉检测值,纹理喜好,食物喜好和成年人挑食行为之间的关系.
- 为了确定客观的触觉敏感性或主观的纹理偏好是否能更好地解释挑食.
主要方法:
- 成年参与者 (n=86) 完成了成人挑食问卷 (APEQ) 和喜欢食物问卷 (FLQ).
- 在舌头和指尖上使用Semmes-Weinstein单丝线来评估触觉值.
- 参与者通过手动与各种纹理互动来测量纹理喜好.
主要成果:
- 在舌头或指尖触觉值和喜欢纹理之间没有发现显著的关系.
- 指尖触觉值与整体食物喜好有很弱的关联,但与挑食得分 (APEQ) 没有直接关联.
- 喜欢纹理与喜欢食物和挑饮食分数 (APEQ) 都有显著的相关性.
结论:
- 挑食者表现出对纹理的主观不喜欢,但这并不能通过客观较低的触觉检测值来解释.
- 这些发现表明,主观纹理评估中的个人差异,而不是感官处理缺陷,是挑食的关键因素.
- 进一步的研究应该探索不同质感喜欢挑食者的发育起源.

Taste Buds and Receptors
1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Conditioned Taste Aversion
118
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Tactile and Chemical Senses
283
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

The Physiology of Taste
3.7K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Gustation
47.6K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
