This research presents the kinetics of saponification reaction using mixed fats olein and stearin [in ratio (3:1)] with NaOH solution. In this reaction, excess solution was used to ensure being irreversible. Three parameters were varied show their effects on rate .They are: percentage (10 % - 100 %) , temperature (100-150)oC stirring speed (400-1100) rpm. It noticed that increasing enhances whi...

This study aimed to find the optimum feed mixture consist of palm stearin (PS), olein (PO), and coconut oil (CO), for chemical interesterification produce cocoa butter alternatives (CBA) with most similar melting profile butter. The was chemically interesterified using sodium ethylate as catalyst at a temperature 75°C 8 hours. Based on analysis products, pure (CO-100) (PS-100) gave alternatives...

A study was conducted to detect and quantify lard stearin (LS) content in canola oil (CaO) using differential scanning calorimetry (DSC). Authentic samples of CaO were obtained from a reliable supplier and the adulterant LS were obtained through a fractional crystallization procedure as reported previously. Pure CaO samples spiked with LS in levels ranging from 5 to 15% (w/w) were analyzed usin...
