Abstract

The invention discloses a pretreatment method for raw materials used in processing of dried Hemerocallis fulva L. The pretreatment method comprises the following steps: S1, soaking fresh Hemerocallis fulva L. in a chlorine dioxide solution with a concentration of 100 to 150 mg / L for sterilization for 12 to 18 min; S2, washing the sterilized fresh Hemerocallis fulva L. with clear water and carrying out enzyme deactivation by using steam with a temperature of 94 to 96 DEG C for 30 to 90 s; and S3, immersing the fresh Hemerocallis fulva L. in cold water for cooling after enzyme deactivation and carrying out rinsing two to three times. The invention has the following beneficial effects: low content of colchicine in the fresh Hemerocallis fulva L. is realized under the condition that a preserving rate of Vc in the fresh Hemerocallis fulva L. is high; the treated Hemerocallis fulva L. has a yellowish green color, most of enzymes are inactivated, microbes are killed, air is eliminated, a good processing effect is obtained, a storage life of the Hemerocallis fulva L. is effectively prolonged, and it is guaranteed the Hemerocallis fulva L. is safe to eat.

Description

technical field [0001] The invention relates to the technical field of pretreatment process before drying flowers and vegetables among vegetables, in particular to a raw material pretreatment method for dried yellow flowers. Background technique [0002] Yellow flower is the common name for Hemerocallis fulva L. among the people, and its aliases include: Daylily, Hemerocallis, etc. According to the introduction of "Compendium of Materia Medica": yellow flowers, sweet and cool, non-toxic, digestible, diuretic, often used to treat blood in the stool, red urine, vomiting blood, red eyes, night blindness, epistaxis, hoarseness, toothache, tuberculosis, hemoptysis, Ulcers, dysentery, postpartum milk retention, mastitis and other diseases. Modern medicine believes that yellow flower has better functions of strengthening the brain, improving intelligence and anti-aging. Japanese scientists listed 8 kinds of brain-invigorating foods, and listed yellow flower as the first, so it is...
