Embodiment 1

[0019] (1) Raw material squeezing: select 15kg of perilla with dark color, no freezing, no rot, no disease and insect pests, and clean it to remove impurities such as sand and sand, and put it into the press for pressing;

[0020] (2) Extraction: Centrifuge the perilla juice with a centrifuge at 2500r / min for 8min to extract;

[0021] (3) Reflux concentration: put the extract in the condensing reflux tube and reflux for 1 hour, and distill the reflux liquid at atmospheric pressure;

[0022] (4) Adsorption and elution: Put the fraction on an AB-8 macroporous resin adsorption column with a height of 3m, a diameter of 0.8m, and a 300kg resin filled with a flow rate of 20M3 / h, and elution with 80% ethanol solvent;

[0023] (5) Distillation and concentration: the above-mentioned eluate is separated from the leaf alcohol by the temperature difference stage condensation recovery method, and then subjected to atmospheric distillation and concentrated to obtain a liquid product.

Abstract

The invention relates to a perillaldehyde extraction method, which is characterized by comprising the following steps: (1) raw material squeezing; (2) extraction; (3) reflux and condensation; (4) adsorption-elution; (5) distillation condensation. In the conventional extraction method, only one product can be produced at a time, while in the provided method, pigment and perillaldehyde can be produced at the same time, the raw material is comprehensively utilized, and the economic profits are increased. Furthermore, the leaf alcohol can be separated by a temperature difference grading condensing recovery method, thus the purity of perillaldehyde is improved, the interference of leaf alcohol is eliminated, and the obtained product has a high purity and bright color and luster.

Description

Technical field [0001] The invention belongs to the technical field of pigment extraction, and specifically relates to a method for extracting perillaldehyde. Background technique [0002] Perilla frutescens, also known as Hongsu and Chisu, is an annual herb in the Lamiaceae family. It is a traditional medicinal and edible plant in my country. It is also one of the first 60 medicinal and food Chinese medicines issued by the Ministry of Health. It is distributed in nearly 20 provinces in my country. Perilla pigment is a water-soluble pigment, and its main components are Perillin and Perillin. It is an anthocyanin pigment and has the advantages of high safety and wide resources. The current research on perilla pigment shows that it has important application value in the fields of food and health products. [0003] As a natural food coloring, perilla red pigment has bright colors and special fragrance, which can increase the flavor of food. It can be widely used in food, medicine, h...
