Abstract

The invention discloses a method for performing ultrasonic-assisted supercritical carbon dioxide extraction on vanilla bean essential oil. The method comprises the following steps: crushing dried vanilla beans into 60 to 90 meshes; performing ultrasonic treatment and adding a solvent, so that the solid-liquid ratio is 1:(0.2-1), the temperature is normal temperature, the power is 200 to 400 W andthe time is 4 to 8 minutes; putting into a supercritical carbon dioxide extraction tank and performing extraction, wherein the flow quantity of the carbon dioxide is 16 to 20 L/h, the extraction temperature is 35 to 45 DEG C, the extraction pressure is 10 to 14 Mpa and the extraction time is 160 to 180 minutes; separating for the first time, wherein the separation pressure is 6 to 8 Mpa and the separation temperature is 35 to 45 DEG C; separating for the second time, wherein the separation pressure is 4 to 5 Mpa and the separation temperature is 25 to 30 DEG C. By the method, the problem thatthe flavor and the aromaticity of perfume are changed by the traditional ethanol extraction method can be solved, the production efficiency of the vanilla bean essential oil is high and the product has pure and natural fragrance.

Description

technical field [0001] The invention relates to the technical field of essential oil production, in particular to a method for extracting vanilla bean essential oil through supercritical carbon dioxide. Background technique [0002] The vanilla bean is the ripe fruit of the vanilla plant of the Orchidaceae vanilla genus, native to the tropical rainforests of southern Mexico through Honduras to Costa Rica. Vanilla beans are now mainly produced in Madascar, Tahiti, Comoros, Réunion, Indonesia and Seychelles, and are also planted in Hainan, Fujian and Yunnan in my country. The unique fragrance of vanilla beans makes it a high-grade cigarette, famous wine, tea and high-grade cakes, biscuits and candies in the food industry. It is known as the "king of food spices" by the world. At present, in-depth research on the aroma of vanilla beans at home and abroad has found that it contains alcohols, acids, aldehydes, ketones, phenols, and esters, and its main volatile aroma components ...
