Abstract
The invention relates to an extraction method of odorless perillaldehyde with a high stability. The extraction method is characterized by comprising the following steps: (1) squeezing raw materials; (2) performing an ultrasonic treatment; (3) extracting; (4) refluxing and condensing; (5) absorbing and eluting; (6) carrying out a membrane treatment; (7) distilling and condensing. In the conventional extraction method, only one product can be produced; while in the provided extraction method, pigment and perillaldehyde can be produced at the same time, the comprehensive utilization of raw materials is achieved, and the economic benefits are increased. Moreover, the leaf alcohol can be separated from the perillaldehyde through a temperature different grading condensation recovery method, thus the perillaldehyde purity is improved, and the interference of leaf alcohol is eliminated. The liquid perillaldehyde extract after the absorption treatment is subjected to a membrane separation treatment so as to reduce the odor or even eliminate the odor. In the extraction method, a special porous resin is adopted in a multi-stage elution technology, and is co-used with a mixed oxidizing agent so as to produce the perillaldehyde, which has the advantages of high color value, no odor, light resistance, heat resistance, and stability.
Description
technical field [0001] The invention belongs to the technical field of pigment extraction, and in particular relates to a method for extracting highly stable odorless perillaldehyde. Background technique [0002] Perilla frutescens (Perilla frutescens), also known as Red Su, Chisu, etc., is an annual herb of the Labiatae family. It is a traditional medicinal and edible plant in my country. It is distributed in nearly 20 provinces in my country. Perilla pigment is a water-soluble pigment, and its main components are perilla ning and perillin. It belongs to anthocyanin pigment and has the advantages of high safety and extensive resources. The current research on perilla pigment shows that it has important application value in food, health products and other fields. [0003] As a natural food coloring, perilla red pigment is bright in color and has a special fragrance, which can increase the flavor of food. It can be widely used in food, medicine, health care, textile and oth...
