Abstract

The invention discloses burdock fermented milk belonging to the field of processing of beverage. The burdock fermented milk is prepared from milk powder, cane sugar and burdock as primary materials by the following steps of homogenizing, sterilizing, cooling, inoculating, keeping warm and fermenting, cooling, stabilizing agent, homogenizing, bulking, cooling, and carrying out after-ripening to form the burdock fermented milk. The beverage disclosed by the invention has fresh scent of burdock, and is low in material cost; the lactic acid bacteria content in the fermented milk is high and can be up to 8-9Log. The beverage has the effects of promoting intestinal health, releasing constipation, maintaining human body metabolic balance and improving immunity of the organism.

Description

Technical field [0001] The invention relates to burdock fermented milk, which belongs to the field of beverage processing. Background technique [0002] Burdock is a biennial herb of Compositae, which is widely distributed and cultivated throughout the country. The fruit, roots, leaves and stems of burdock can be used medicinally, and the roots, stems and leaves of burdock are widely used in Japan, southeast and other regions for cooking and eating vegetables. China's burdock is mainly exported fresh, and only a small part is used for deep processing, which makes the economic added value of burdock low. [0003] Burdock is rich in oligosaccharides, which can regulate the function of the intestinal tract and promote the beneficial microbial flora in the intestinal tract, thereby enhancing the body's immunity. Lactic acid bacteria fermented drinks are one of the foods favored by consumers in recent years, and functional oligosaccharides are new health-care sugar products tha...
