AI Technical Summary

Technical Problem

Existing methods for suppressing oxidative deterioration and reducing peroxide values in refined edible oils and fats face challenges such as flavor issues from added antioxidants, complex manufacturing processes, and inefficiencies in removing oil-soluble substances, particularly in highly unsaturated oils.

Method used

The method involves adding phosphoric acid to refined edible oils to enhance antioxidant activity, thereby suppressing oxidation and reducing peroxide values, which can be further enhanced by heating the oils.

Benefits of technology

This approach effectively suppresses oxidative degradation and regenerates oxidized refined edible oils by generating insoluble matter that reduces peroxide values, maintaining flavor quality and extending shelf life.

Abstract

This invention provides a method for producing an edible oil composition that can easily suppress the oxidative degradation of refined edible oils, and a method for regenerating refined edible oils that have deteriorated due to oxidation. [Solution] The present invention provides a method for producing an edible oil composition, characterized by adding an effective amount of phosphoric acid to refined edible oil to suppress the oxidation of the refined edible oil, thereby obtaining an edible oil composition containing the phosphoric acid. The present invention provides a method for regenerating refined edible oil, characterized by adding phosphoric acid to refined edible oil with an elevated peroxide value and heating it.
