At the same time, glycerin can also interact with other ingredients in food to form a stable emulsion or colloid system to improve the taste and texture of food. In the composite antioxidant enhancer, food-grade glycerin, as a carrier, can help other antioxidant ingredients to be better dispersed and dissolved in food, thereby improving the overall antioxidant effect. Rosemary essential oil, tea polyphenols, aloe polysaccharides, curcumin and food-grade glycerin each play an important role in the composite antioxidant enhancer. They work synergistically to significantly improve the antioxidant capacity of food, extend the shelf life of food, and maintain the freshness and taste of food.

When the raw materials are extruded, The raw materials are extruded and sheared through the strip shear holes. A plurality of unloading holes are arranged in an array at both ends of the middle of the outer end surface of the shear tube. When the pressure in the middle of the shear tube is extremely high, the first spiral blade and the third spiral blade absorb the raw materials at the same time during rotation and discharge them from the unloading holes under the action of pressure, thereby preventing the continuous pressurization inside the shear tube from causing damage to the shear tube. At the same time, when the raw materials are discharged from the unloading holes, they will also undergo partial extrusion and shearing, and the raw materials will be quickly broken up and recombined into smaller units through the shear tube to form a uniform and stable emulsion, so that the raw materials are fully mixed.

[0024] 3. In the invention, through the setting of the third conical teeth, the upper and lower ends of the two third conical teeth are respectively meshed and connected with the teeth on both sides of the first conical teeth on the rotating tube and the second conical teeth on the rotating shaft. When the rotating shaft rotates, the second conical teeth are driven to rotate, and the first conical teeth are driven to rotate in the opposite direction through the transmission of the third conical teeth, thereby driving the rotating tube to rotate in the opposite direction. The rotation of the rotating tube simultaneously drives the first spiral blade and the second spiral blade to rotate. When the second spiral blade rotates, it drives the internal raw materials to circulate, thereby improving the mixing efficiency of the raw materials and realizing the coaxial reversal of the rotating tube and the rotating shaft.

10. A preparation method, based on a composite antioxidant enhancer containing rosmarinic acid according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Rosemary essential oil, tea polyphenols, aloe polysaccharide, curcumin, and food-grade glycerin are respectively injected into a plurality of raw material monomer storage tanks (2) through a feeding pipe (201) for storage, and each raw material is accurately injected into a mixing tank (1) according to a proportion through a metering pump (202) at the lower end of the raw material monomer storage tank (2); Step 2: The rotating shaft (6) is driven to rotate by the high-speed motor (304), and when the rotating shaft (6) rotates, the second conical teeth (602) are driven to rotate, and the first conical teeth (503) are driven to rotate in the opposite direction through the third conical teeth (701), thereby driving the rotating tube (5) to rotate in the opposite direction. The rotation of the rotating tube (5) simultaneously drives the first spiral blade (501) and the second spiral blade (502) to rotate, and when the second spiral blade (502) rotates, it drives the internal raw materials to circulate, thereby improving the mixing efficiency of the raw materials; Step 3: When the rotating shaft (6) rotates, it drives the third spiral blade (601), so that the first spiral blade (501) and the third spiral blade (601) rotate in a mirror image inside the shearing tube (402), so that the first spiral blade (501) and the third spiral blade (601) simultaneously absorb the raw materials at the upper and lower ends of the shearing tube (402) when rotating, and transport them to the middle part of the shearing tube (402), so that the raw materials are squeezed in the middle part of the shearing tube (402) and extruded from the strip shearing hole (403), and the raw materials are squeezed and sheared through the strip shearing hole (403) when the raw materials are extruded; Step 4: A plurality of unloading holes (404) are arranged in an array at both the upper and lower ends of the middle portion of the outer end surface of the shear tube (402). When the pressure in the middle portion of the shear tube (402) is extremely high, the first spiral blade (501) and the third spiral blade (601) simultaneously absorb the raw materials during rotation and discharge them from the unloading holes (404) under the action of pressure, thereby preventing the shear tube (402) from being continuously pressurized and causing damage to the shear tube (402). At the same time, when the raw materials are discharged from the unloading holes (404), they will also undergo partial extrusion and shearing, so that the raw materials are quickly broken up and reassembled into smaller units through the shear tube (402) to form a uniform and stable emulsion, so that the raw materials are fully mixed, and the mixed emulsion is discharged from the mixing tank (1) for storage.
