Abstract

ABSTRACT

A rapid method for quantitative determination of free fatty acids from crude palm oil to bleached palm oil (BPO) and then distilled BPO and refluxed BPO by Fourier transform infrared (FTIR) transmission spectroscopy is described. A partial least square (PLS) model was calibrated to predict the FFA content of palm oil samples based on the spectral range of 1,729.89–1,694.48/cm. Multivariate calibration step was carried out by comparing the FFA values predicted by PLS model to the values obtained from the official American Oil Chemists' Society method. The resulting PLS calibrations were linear and the root mean standard error of cross-validation was 0.063 with a correlation coefficient (R²) of 0.9898. The results indicated that FTIR spectroscopy is an efficient, rapid and accurate method for determining the FFA content in palm oil.

PRACTICAL APPLICATION

The application of Fourier transform infrared (FTIR) spectroscopy technique was studied to confirm the free fatty acid (FFA) content in bleached deacidified palm oil obtained from solvent deacidification process. FTIR spectroscopy afforded accurate results within a short period of time in a simple manner. Thus, FTIR is considered as a rapid, simple and solvent-free alternative analytical method for determination of FFA content in edible oils.

傅里叶变换红外光谱法测定粗棕榈油、漂白棕榈油和漂白脱酸棕榈油中的游离脂肪酸

摘要建立了用傅里叶变换红外光谱(FTIR)快速测定粗棕榈油-漂白棕榈油-蒸馏油-回流棕榈油中游离脂肪酸含量的方法。在1729.89 ~ 1694.48 /cm的光谱范围内，采用偏最小二乘(PLS)模型对棕榈油样品的游离脂肪酸含量进行了预测。通过将PLS模型预测的FFA值与美国石油化学家协会官方方法获得的值进行比较，进行多变量校准步骤。交叉验证的均方根标准误差为0.063，相关系数(R2)为0.9898。结果表明，FTIR光谱法是一种高效、快速、准确的测定棕榈油中游离脂肪酸含量的方法。应用傅里叶变换红外(FTIR)光谱技术测定了溶剂脱酸过程中脱色的棕榈油中游离脂肪酸(FFA)的含量。FTIR光谱在短时间内以简单的方式提供准确的结果。因此，FTIR被认为是一种快速、简便、无溶剂的食用油中游离脂肪酸含量的替代分析方法。
