What is sample coding in sensory evaluation?

Sample coding in sensory evaluation refers to the practice of assigning unique identifiers or codes to different samples being tested, rather than using their names or labels. This approach helps to minimize bias and ensures that panelists evaluate the samples based solely on sensory attributes, such as taste, smell, and texture, without preconceived notions. The codes are typically randomized to further eliminate any patterns that could influence perceptions. This method is crucial for maintaining objectivity and reliability in sensory assessments.
