Transcript of "Organoleptic shelf life evaluations"

  1. 1. OrganolepticShelf Life Evaluations Ivy Cho Lorenzo PuentesBusiness Development Director Director of Product Performance ivyc@abcr.com lorenzop@abcr.com
  2. 2. What does shelf life mean? • It is the extent of time for which a food remains usable, fit for consumption, or sellable from manufacturing until reaching the “best before date”, “expiration date”, or “use by date”. – These terms all relate to the quality of the foodOrganoleptic Shelf Life Evaluations
  3. 3. Terms used to describe shelf life • “best before date” or “expiration date” – Where deterioration affects consumer acceptance • “use by date” – The time period when foods are to be eaten for health or safety reasonsOrganoleptic Shelf Life Evaluations
  4. 4. Shelf life influencers Growers/ Producers Other suppliers Manufacturers Distributors Retailers ConsumersOrganoleptic Shelf Life Evaluations
  5. 5. Factors that affect the shelf life • Moisture • Water activity • Fat/oil content • Alcohol content • Flavor loss • Texture changes • Color changes • Acid content • pH • Light exposure • Microbial spoilageOrganoleptic Shelf Life Evaluations
  6. 6. Types of shelf life evaluations 1. Accelerated – This is applicable in shelf stable foods where the storage temperature is increased to accelerate time. 2. Real Time – This is applicable in ambient, refrigerated, and frozen foods where the storage temperature is real time. – Microbiological evaluations are applicable in ambient and refrigerated foods.Organoleptic Shelf Life Evaluations
  7. 7. Accelerated shelf life • Attempts to predict the shelf life by use of temperature chambers to increase the rate of deterioration. • 100F chamber is used to store liquids – i.e. sauces • 90F chamber is used to store non-liquids – i.e. spicesOrganoleptic Shelf Life Evaluations
  8. 8. Types of organoleptic panels • Affective Tests – Used to assess consumer responses to products • May be Qualitative or QuantitativeOrganoleptic Shelf Life Evaluations
  9. 9. Qualitative vs. Quantitative • Qualitative – Used to evaluate consumer’s feelings about a product – Focus Groups • Quantitative – Used to identify overall preference or liking of a product or specific attribute. - Simple Preference Testing - Ranking TestsOrganoleptic Shelf Life Evaluations
  10. 10. Acceptance Tests • Likability Scales – 9 point hedonic • Just About Right Scales otherwise known as “JAR” –Applicable for formulation changes or product development stages • Line Scale or Numerical Scales • Food Action Rating ScalesOrganoleptic Shelf Life Evaluations
  11. 11. Descriptive Analysis Testing • Used to provide descriptions of the sensory quality of foods • Trained Panels • Flavor ProfilesOrganoleptic Shelf Life Evaluations
  12. 12. Real time shelf life • Foods are stored under normal conditions for a time length greater than the expected shelf life to determine the deterioration point.Organoleptic Shelf Life Evaluations
