1. A process for the production of monoglycerides by glycerolysis comprising:

  • i) reacting methyl ester derived from animal or vegetable fat and oils by mixing a surplus of 0.1 to 3 moles of glycerol in relation to methyl ester;

    ii) subjecting the reaction mixture to reaction temperature between 130°

    to 160 °

    C. at a vacuum of 200 to 400 mbar;

    iii) adding alkaline catalysts; and

    iv) stopping the reaction by fast cooling of the reaction mixture and the destruction of the alkaline catalyst when the quantity of glycerides has reached a concentration of 40 to 60% and the ratio of concentrations of mono and diglyceride lies between 3 to 10.
