discriptive analysis (analysis techniques (quantitative descriptive…

- - - - group rating
      - vocab develoment and attribute rating are based on group discussion
  - - - machinical + geometrical + other charac
    - - result consistent and accurate + good for skincare and cosmetic products
    - - time consuming + may require new selection of products for reference points + availability of products (as ref points) in other countries
  - - - generate their own terms
      - adopt terms from a langyage developed by another
    - - technical principles of each attribute category + understanding of physiology and psychology of sensory perception
      - training several months
      - panel leader teaches the planelist
      - use scale achored by ref points + intensiy scale is absolute
    - - panelists use scales in the same way (cannot be deviated) + appropriate tech for quality assurance
    - - difficult panel development and maintainance + time consuming + availability of products (as ref points) in other countries
  - - - use frequently consumer
    - - use non-technical + everday language
    - - define and select ref.standard
      - ref used when needed
    - - not calibrated to use the scale in the same way
      - focus on relative differences among product --> so it is OK that people agree that 1 is better than 2 even not marking at the same scale
    - - no influence from panel leader + able to use statistcis to analyze data + less time consuming
    - - panels must be trained for specific product category + expensive (for small firm)
  - - - ex. how sweetness change after eating
- - - - ability to discriminate- can be measured using discrimination test
      - allergies, denatures, physiology
      - motivations
      - product usage
        
        ex. selecting soft drinker to test soft drink is better
  - - - def: aromatic associated with akali processed cocoa
      - ref std: Hershey's cocoa powder
    - - aromatics associated with caramelized milk product
      - autoclave whole milk at 121C for 25 mins
    - - chemical feeling factor producing a dry sensation
      - tea solution (6 tea bags soaked in 1 quart of hot water for 1 hour)
  - - - ability to determine
      - repeatability
        
        5 times in rep 1 = 5 times in rep 2
      - consitency
        
        5 times for 1 person = other also 5 times
