| 摘要≠ | Just-About-Right (JAR) Scaling is a consumer-based sensory evaluation method that asks respondents to rate sensory attributes not on intensity alone, but on whether they perceive the attribute as too weak, just right, or too strong for the product. Developed by Lawless in the mid-1990s, JAR scaling bridges the gap between descriptive sensory analysis and consumer preference, directly linking attribute levels to consumer satisfaction. | Quantitative Descriptive Analysis (QDA) is a comprehensive sensory evaluation method developed by Stone and colleagues in the 1970s that uses a trained panel to describe the intensity of sensory attributes in food products. QDA provides detailed, quantitative profiles of flavor, aroma, texture, and appearance, allowing researchers and product developers to characterize and compare products objectively. |
