Physico-chemical properties of palm stearin, soybean oil and their binary blends / Nabilah Abdul Hadi

The objective of this study was to determine the changes in physicochemical properties of palm stearin (PS) and soybean oil (SBO) blends at different mixing ratios in order to identify the suitable blend ratio of PS and SBO for certain food applications. Palm stearin was blended with SBO at differen...
