Study Notes
Definition and Evolution of Sensory Evaluation
- Sensory evaluation is a scientific method that evokes, measures, analyzes, and interprets responses to products as perceived through the senses of sight, smell, touch, taste, and hearing.
- It has developed into a dynamic and constantly evolving discipline recognized as a scientific field in its own right since its emergence in the 1940s.
Categories of Sensory Testing
- Sensory evaluation can be divided into two categories: objective and subjective testing.
- Objective testing (Discriminative & Descriptive) evaluates sensory attributes of a product using a selected or trained panel.
- Subjective testing (Affective) measures consumers' reactions to the sensory properties of products.
Role of Sensory Evaluation
- The role of sensory evaluation has changed considerably over the years, shifting from being a service provider to a partner with R&D and marketing in guiding development and commercial strategy.
- Sensory professionals inform decision-making during a product's life cycle, from conception to post-launch monitoring.
Applications of Sensory Evaluation
- Sensory testing helps identify important sensory attributes driving acceptability across a product category.
- It can identify sensory-based target consumer segments, analyze competitor products, and evaluate new concepts.
- Combining sensory and instrumental testing data can provide insights into chemical and physical properties driving sensory attributes.
- Sensory testing can determine the impact of scaling up production, detect changes in raw ingredients, and ensure quality assurance.
Quality Assurance and Shelf Life
- Sensory testing can set consumer acceptability limits for sensory specifications used during quality testing.
- It can ensure substandard products are not released onto the market, particularly for products susceptible to taints.
- Sensory testing, along with microbial tests, can determine shelf life and product variability through the supply chain.
