Hydrotherm: A Case Study

  1. 1. Fat Determination Study -Hydrotherm vs. AOAC 922.06
  2. 2. Nutrient used as an energy source1 g = 9 calories (38 kilojoules)Referred to as a lipid
  3. 3. Importance of FatNutritionAppearanceTextureFlavor
  4. 4. Fat DeterminationFDA mandate for food labelTotal Fat, Saturated Fat, Trans Fat, Cholesterol“Good” and “Bad” fat
  5. 5. Fat ExtractionExtractable fat = “free fat”Bound fat needs to be extractedMethods to measure Total Fat (free + bound) Weibull-Stoldt AOAC 922.06
  6. 6. Calculating Total Fat ContentSum ParameterSample MatrixFatty Acid Spectrum
  7. 7. Study BackgroundFat extraction of 21 different productsTraditional AOAC 922.06 vs. Hydrotherm/Weibull-StoldtFood and Feed samples testedOver 1,000 data points collected
  8. 8. Test EquipmentTraditional AOAC 922.06Weibull-Stoldt

  10. 10. Benefits ofWeibull-Stoldt /Hydrotherm MethodCost savingsTime savingsReproducible ResultsImproved precisionHigh through-putUniversalNo fume hood required
  11. 11. ObservationsOverall Testing EaseCost SavingsSignificant Time SavingsSafety Advantages
  12. 12. ConclusionsWeibull-Stoldt/Hydrotherm exceeds AOAC standards9 of the 21 products had higher fat recoveriesSignificant time savings are 7 minutes per sample22% cost reduction per sample“The elimination of flammable hazardous waste allows theHydrotherm….to be greener and environmentally friendly.”
