概括
使用消费者和描述性数据评估了牛肉的柔软性和果汁性. 华纳-布拉茨勒切削力 (WBSF) 与描述性柔软性比消费者感知更好地相关,特定的WBSF值表明柔软度水平.
科学领域:
- 食品科学与技术 食品科学与技术
- 肉类科学 肉科学
- 感官分析 感官分析
背景情况:
- 牛肉的质地主要是由温柔和多汁性来定义的.
- 之前的研究已经研究了影响牛肉质感的因素,但缺乏最近的美国消费者数据,将感官属性与客观措施相关联.
- 了解这些关系对于预测消费者满意度至关重要.
研究的目的:
- 阐明消费者和受过训练的描述性感官数据之间的关系,以了解牛肉的柔软性和果汁性.
- 为了将这些感觉属性与华纳-布拉茨勒切削力 (WBSF) 和整体消费者喜好相关联.
- 为预测牛肉质地质量建立客观的指标.
主要方法:
- 分析了两个数据集:上部腰部牛排 (n=119) 和更广泛的牛肉切片 (n=276).
- 利用消费者的感官数据和训练有素的描述面板数据来测量温柔和果汁性.
- 与华纳-布拉茨勒切削力 (WBSF) 测量和整体消费者喜欢分数相关联的感觉数据.
主要成果:
- 华纳 - 布拉茨勒切削力 (WBSF) 与描述性柔软度评级 (R2=0.37对于牛肉切片) 相比,与消费者柔软度属性更为密切相关.
- 消费者的整体喜好与口味的喜好高度相关 (牛肉切片R2=0.94).
- 描述性和消费者果汁度评级并没有显著改善WBSF或整体喜好的预测.
结论:
- 低于28N的WBSF值表明牛肉温和度适度,而30-32N则表明牛肉稍微温和.
- 具有WBSF值≥40N的牛肉被归类为稍强硬或更强硬.
- 描述性温柔性比消费者认知更好地预测WBSF,这凸显了训练有素的专家小组对客观质量评估的重要性.

Taste Buds and Receptors
2.2K
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,...

The Physiology of Taste
4.0K
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...

Sensory Perception: Organization of the Somatosensory System
3.1K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Sensory Functions of the Skin
5.1K
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...

Assessment of the Gastrointestinal System I: Subjective Data
224
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Moisture Content and Bulking of Aggregate
178
The moisture content of aggregates is a crucial factor in construction, particularly in concrete mixing, as it influences the total water required in the mix. Moisture content represents the water coated on the exterior surface of the aggregate existing in a saturated and surface-dry condition. The total water content of a moist aggregate is the sum of its moisture content and water absorption.
When aggregates are exposed to rain or sit in stockpiles, they absorb moisture, which must be...
