The ORACLE: Universal Rapid Fat Testing System

The ORACLE is a low-resolution, rapid NMR technology that accurately analyzes fat in any unknown food sample without the need for method development. It aims to be the standard reference technique for fat testing worldwide.

Presentation Transcript

  1. Current fat testing limitations • Rapid techniques (NMR, NIR, FT-IR, etc.) • Method development required • Matrix dependent • Reference methodology • Long analysis times (hours) • Skilled chemists • Hazardous chemicals (safety & disposal) • Repeatability issues

  2. Original Scope Design Goal: Create a universal fat system that removes the bottlenecks and limitations of reference chemistries and rapid techniques. Design a rapid system that no longer requires any form of method development. Long-term vision: To become the standard reference technique for fat testing worldwide

  3. What is the ORACLE? • Low Resolution, rapid NMR that requires NO fat method development • Accurately analyzes fat in ANY unknown food sample

  4. How it works The ORACLE utilizes a breakthrough NMR technology developed by CEM that overcomes the deficiencies of previous NMR technologies. Two improvements over Trac technology • Isolates detection of proton signals on fat molecules from all other sample components • Eliminates partial decay signals of varying fat molecules

  5. Validation of Technology • ~30 CRM’s analyzed on ORACLE • Samples extensively tested in collaborative studies (typically 10+ certified laboratories) • CEM outsourced 100’s of samples to Eurofins and Silliker • Submitted samples in “blind” and “non-blind” fashion to capture true sample variability

  6. Certificate of Analysis (COA) • Accompanies every CRM sample • Information varies slightly based on where it was sourced (e.g. Muva Kempten vs. NIST) • Assessed values for determined components (e.g. fat/oil, moisture, protein, ets) • Explanation of Statistics • Suggested sample sizes • Handling/Preparation instructions • Shelf life

  7. CRM Samples Run on ORACLE

  8. Further Validation from Actalia • Actalia is a COFRAC accredited lab in France • Validates equipment for the dairy industry • High respected by ISO and IDF • Seen as “experts” in dairy analysis

  9. Actalia Study • 2 major conclusions from ORACLE testing • The ORACLE “..reproducibility of the instrument is lower than the reproducibility of the reference method.” • The accuracy of the ORACLE compared to reference chemistry showed the “…regression slope (0.999) and the intercept (0.009) are not significantly different, respectively from 1.00 and zero (P=5%).”

  10. Using the ORACLE

  11. Simple to Operate • Designed so that anyone can operate • Simply touch “run” button to start analysis • No method development or chemists required

  12. Two Ways to Operate Rapid- SMART 6 High Throughput- Oven Testing labs running 50+ samples per day Dry samples overnight in oven Condition 1 hour in CEM Precision Heater Block and then analyze fat in ORACLE • Process control labs that need rapid moisture & fat results • Results = < 5 minutes • Dry samples in the SMART 6 for moisture results and then analyze fat in ORACLE

  13. ORACLE & SMART 6

  14. SMART 6 + ORACLE • Ideal for process control customers requiring rapid results (i.e. food production facilities) • Results in 3-5 minutes • Analyze moisture and fat in any sample- wet or dry

  15. SMART 6 + ORACLE Procedure SMART 6 Moisture Analysis 2-4 minutes Condition in QuikPrep 30 seconds ORACLE Fat Analysis 30 seconds

  16. ORACLE & Air Oven

  17. Air Oven Testing Sequence ORACLE Fat Analysis 30 seconds Condition in Heater Block 30-60 minutes Dry in Oven Overnight

  18. Robot • Option with High Throughput customers • For use with one or two 50-place heater blocks • Allows users to walk away after conditioning begins • Automated sample analysis allows lab techs to focus on other testing needs

  19. Global Repeatability • All ORACLEs are designed to produce the same NMR signal • Ensures consistent results across suppliers and manufacturers worldwide

  20. ORACLE vs Reference Chemistry

  21. Current fat testing limitations • Rapid techniques (NMR, NIR, FT-IR, etc.) • Method development required • Matrix dependent • Reference methodology • Long analysis times (hours) • Skilled chemists • Hazardous chemicals (safety & disposal) • Repeatability issues

  22. Reference Chemistry Woes • Blanket methods not necessarily optimized for samples • Using the wrong method can greatly effect the final % Fat result Aued-Pimentel et al. Quim. Nova, 2010, 33, 76 – 84

  23. Error at Certified Reference labs • Blind submittals show true error of a reference method • Outside labs may choose to omit certain duplicate results, especially if range is large. Customer would not know. • Blind submittals less susceptible to omission Dairy Powders

  24. Inter-laboratory Error • Sample was prepared and split at CEM, so both labs received identical samples

  25. Intralaboratory- Infant Formula Retest

  26. Intralaboratory- Lay’s Baked BBQ Chips Retest * Note- only sample 3 retested “Weighing Error”

  27. ORACLE vs NIR/FT-IR

  28. Current fat testing limitations • Rapid techniques (NMR, NIR, FT-IR, etc.) • Method development required • Matrix dependent • Reference methodology • Long analysis times (hours) • Skilled chemists • Hazardous chemicals (safety & disposal) • Repeatability issues

  29. CEM Accuracy Advantage NIR - FOSS CEM – ORACLE AOAC Method 2008.06 AOAC Method 2007.04 Moisture Average Difference +/- 0.20% Average Difference +/- 1.03% Fat Average Difference +/- 0.36% Average Difference +/- 0.03% Displaying unbiased data from each system’s AOAC method as proof of undeniably better accuracy

  30. Cost of Ownership • NIR costs based on suggested maintenance of ANN calibrations • 2 components (Moisture, Fat) • $25/sample reference testing cost • No reformulations or recalibrations, only typical maintenance • CEM costs basedon consumables for SMART 6, ORACLE, and Sprint • 2 components (Moisture, Fat) • List price (can be decreased based on purchase quantity)

  31. One System, Any Sample • Moisture and Fat analysis for any sample can be tested on the ORACLE • Liquid, Powder, semi-solid, cultured, and more • NIR AND FT-IR must be used to analyze the full range of samples • FT-IR for liquid, NIR for cultured and powder • Increased costs instruments, service, calibrations, software upgrades • New products require new NIR/FT-IR calibrations, which require additional time and capital
