What is Fat?

Nutrient used as an energy source
1 g = 9 calories (38 kilojoules)
Referred to as a lipid

SLIDE 3

Importance of Fat

Nutrition
Appearance
Texture
Flavor

SLIDE 4

Fat Determination

FDA mandate for food label
Total Fat, Saturated Fat, Trans Fat,

Cholesterol

“Good” and “Bad” fat

SLIDE 5

Fat Extraction

Extractable fat = “free fat”
Bound fat needs to be extracted
Methods to measure Total Fat (free + bound)
Weibull-Stoldt
AOAC 922.06

SLIDE 6

Calculating Total Fat Content

Sum Parameter
Sample Matrix
Fatty Acid Spectrum

SLIDE 7

Study Background

Fat extraction of 21 different products
Traditional AOAC 922.06 vs. Hydrotherm/Weibull-Stoldt
Food and Feed samples tested
Over 1,000 data points collected

SLIDE 11

Observations

Overall Testing Ease
Cost Savings
Significant Time Savings
Safety Advantages

SLIDE 12

Conclusions

Weibull-Stoldt/Hydrotherm exceeds AOAC standards
9 of the 21 products had higher fat recoveries
Significant time savings are 7 minutes per sample
22% cost reduction per sample
