Abstract

The invention discloses an application of a chicoric acid extract in echinacea purpurea, namely, an application of the chicoric acid extract as an edible fat and oil antioxidant. A purified chicoric acid extract extracted from the echinacea purpurea is added in edible fat and oil according to a certain dosage, and the antioxygenation function of the chicoric acid extract of the echinacea purpurea is simultaneously achieved by using three methods of measuring acid value (AV), peroxidation value (POV) and thiobarbituric acid (TBA) of fat and oil, results prove that the chicoric acid extract in the echinacea purpurea has a remarkable antioxygenation effect to lard oil and colleseed oil, can effectively delay the lipid peroxidation of the fat and oil, and can be applied to the food industry.

Description

technical field [0001] The invention belongs to the field of food additives, in particular to the application of cichoric acid extract from Echinacea purpurea as an antioxidant of edible oil. Background technique [0002] Echinacea purpurea (Echinacea purpurea L.), also known as Echinacea purpurea L., is a perennial herb of the genus Echinacea in the Asteraceae family. Echinacea purpurea has the functions of enhancing cellular immunity and humoral immunity, antibacterial and antiviral, and has been widely valued in the world. It mainly treats and prevents infections caused by various pathogens, and is especially effective for upper respiratory tract infections. The main chemical components of Echinacea purpura include caffeic acid and its derivatives, polysaccharides and glycoproteins, and alkylamides. [0003] Chichoric acid belongs to caffeic acid derivatives, is one of the most abundant phenolic compounds in Echinacea purpurea, and is also one of its main characteristic ...
