概括
中的化合物素会引起口腔烧伤, 这与之前的研究不同, 表明随着燃烧的加剧超出了最佳范围,
科学领域:
- 感官科学
- 食品科学
- 人类心理物理
背景情况:
- 之前的研究表明素 (TRPV1激动剂) 在模型系统中引起单调的口腔烧伤敏感性.
- 现实世界中的饮食经验表明,
- 了解素在自然饮食中的作用对于食品开发至关重要.
研究的目的:
- 在受控环境中使用真实食物 (肉提卡马萨拉) 调查素敏感性和喜好.
- 将结果与之前的素暴露模型研究进行比较.
- 为了确定口服烧伤的轨迹和重复消费的快乐反应.
主要方法:
- 75名成年人每隔30秒食用10个15克的肉.
- 参与者使用一般标记大小尺度 (gLMS) 和一般双极享乐尺度 (gHS) 评价口腔燃烧和喜好.
- 随机系数模型分析了重复暴露与感官评分之间的关系.
主要成果:
- 口腔烧伤呈现出曲线状,正方形的轨迹,最初增加,然后随着重复暴露而平稳 (p < 0. 001,p = 0. 002).
- 喜欢度 (喜欢度) 在所有曝光中显著下降 (p = 0.01).
- 燃烧强度和喜欢的轨迹有所不同,这表明随着燃烧超过最佳水平,喜欢度会下降.
结论:
- 在真实食物中的口腔烧伤显示出二次轨迹,而不是像模型系统中看到的单调增加.
- 这项研究强调了受控刺激和自然饮食体验之间的区别,
- 研究结果表明,感官特异性和或高燃烧对喜欢的直接负面影响可能解释快乐的下降.

01:14Conditioned Taste Aversion
228
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...

01:20Desensitization and Tachyphylaxis
2.2K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

01:16Sensory Functions of the Skin
5.7K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:20Taste Buds and Receptors
2.8K
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,...

01:43Thermosensation
31.8K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
