Baking natural antioxidant and preparation method thereof

The invention discloses a baking natural antioxidant and a preparation method thereof, and belongs to the technical field of food additives. The baking natural antioxidant comprises a tea extract, an aronia melanocarpa fruit extract, a bamboo leaf extract, polyglycerol polyricinoleate, Tween 80, sunflower seed oil and water, wherein the mass ratio of the tea extract, the aronia melanocarpa fruit extract, the bamboo leaf extract, the polyglycerol polyricinoleate, the Tween 80, the sunflower seed oil and the water is (20-60):(5-20):(5-20):(0.3-2.0):(0.2-1.5):(15-40):(20-60). The compound natural antioxidant is liquid and can be dissolved in a water system, so that the green tea extract, the aronia melanocarpa extract and the bamboo leaf extract can be better mixed with baking grease, especially water-containing artificial butter, and the application range of the three extracts is expanded; in addition, layering and precipitation are avoided after long-term storage. 本发明公开了一种烘焙天然抗氧化剂及其制备方法，属于食品添加剂技术领域。本发明所述的烘焙天然抗
