Petaling Jaya, Malaysia Technique for Quality Control of Specialty Fats Using the PerkinElmer Frontier FT-MIR/NIR System Precise FT-IR Spectroscopy Introduction In the process of refining crude palm oil (CPO) into refined, bleached and deodorized palm oil (RBDPO) for specialty fat production, the palm oil industry spends millions of Euros for chemicals needed in its quality control efforts of RBDPO. Due to its high chemical usage, the CPO industry faces enormous waste treatment costs. The quality control parameters in the manufacturing of specialty fats, such as Free Fatty acid (FFA), Iodine Value (IV), moisture and impurities (MI), Peroxide Value (PV), and slip melting point (SMP), not only consume many chemicals, they also harbor the potential to cause environmental issues if left untreated. To help reduce those issues, PerkinElmer has developed a rapid FT-IR method using its Frontier™ FT-IR Infrared Spectrometer System. What follows is a report on how the Frontier FT-IR can provide an effective, environmental friendly solution that will save the palm oil industry both time and money. i> Perkin Elme ’ For the Better

Instrument Settings and Calibration Models Using Chemometrics Oil blends of specialty fats were injected into BaF2 window liquid cell at 65 °C with Spectral resolution of 8 cm-1, 32 scan. PerkinElmer Frontier FT-IR was used for transmission measurement covering a range from 4000 - 400 cm-1 (Figure 1). Calibration models of FFA, IV, MI, PV and SMP were performed using PerkinElmer Spectrum Quant Advance Chemometric software. Figure 1. PerkinElmer Frontier MIR System.

The calibration involves scanning the sample in heated liquid cell and is a fast method to determine minute amounts of above mentioned parameters in specialty fats (Figure 2). The FT-IR spectrum in Mid-IR region ensures better and more precise quantitative predictions compared to conventional Near-IR measurements due to strong IR peak absorption in Mid-IR region. PerkinElmer Frontier FT-IR system features: Preset calibrations or only requiring calibration fine-tuning • on site with ready method settings for quick start Heatable liquid cell for transmission measurement of the • oil samples Preheater...
