Embodiment 1

[0018] 10 parts of carboxyalkyl β-cyclodextrin, 100 parts of solvent water, heated to 60°C to make a solution, add 1 part of cinnamon oil dropwise; stir, control the temperature of the system to drop to room temperature at a rate of 15°C per hour, and continue stirring 1 hour. Cool at about 0°C for 24 hours, filter out the precipitate, and dry to obtain an inclusion compound of cinnamon oil and carboxyalkyl β-cyclodextrin, and the utilization rate of cinnamon oil is 91.8%.

Embodiment 2

[0020] 12 parts of carboxyalkyl β-cyclodextrin, 250 parts of solvent water, heated to about 55°C to make a solution, and 1 part of cinnamon oil was added dropwise; Stir, control the temperature of the system to drop to room temperature at a rate of 15°C per hour, continue Stir for 2 hours. Cool in an environment around 0°C for 24 hours, filter out the precipitate, wash the clathrate with a small amount of water and ethanol until there is no smell of cinnamon oil, and dry to obtain the clathrate of cinnamon oil and carboxyalkyl β-cyclodextrin , The utilization rate of osmanthus oil was 81.52%.

Embodiment 3

[0022] 10 parts of carboxyalkyl β-cyclodextrin, 130 parts of solvent water, heated to 50°C to make a solution, and 0.7 part of cinnamon oil was added dropwise; stirring, the temperature of the system was lowered to room temperature at a rate of 20°C per hour, and continued stirring 1 hour. Cool in an environment around 0°C for 24 hours, filter out the precipitate, wash the clathrate with a small amount of water and ethanol until there is no smell of cinnamon oil, and dry to obtain the clathrate of cinnamon oil and carboxyalkyl β-cyclodextrin , the utilization rate of osmanthus oil was 83.18%

Abstract

A modified beta-dextrin / bay leaves oil inclusion compound is prepared from carboxyalkyl beta-dextrin and bay leaves oil through inclusion in pure water solution while stirring. Its advantages are high output, high solubility and high transparency.

Description

technical field [0001] The invention relates to a modified β-cyclodextrin / cinnamon oil clathrate and a preparation method thereof. technical background [0002] Cinnamon oil is a natural plant essential oil, yellow or brown liquid, the main component is cinnamaldehyde. It has the special aroma of cinnamon, pungent and sweet, and has the functions of sterilizing, expelling wind and invigorating the stomach. It is not only widely used in traditional Chinese medicine and preparations, but also used in beverages and food flavor enhancers, and in the preparation of cosmetic essences and soap essences. Cinnamon oil has poor water solubility and is easily volatile and oxidized in the air. Inclusion of cinnamon oil and β-cyclodextrin, after inclusion, cinnamon oil can be dissolved in water to prevent cinnamon oil from volatilization and oxidation in the air. In traditional Chinese medicine and preparations, the accuracy of the formula can be guaranteed, an...
