AI Technical Summary

Technical Problem

Existing coffee extracts have a high caffeine content, making it difficult to meet the regulatory requirements for electronic atomization devices. Furthermore, traditional extraction methods suffer from high production costs, significant flavor loss, and low production efficiency.

Method used

A method combining supercritical extraction and molecular distillation is used to extract coffee beans with supercritical carbon dioxide, separating caffeine while retaining the main aroma components. The coffee extract is then blended with monomeric flavorings to form a low-caffeine atomizing matrix.

Benefits of technology

This technology enables the production of coffee extracts with low caffeine content, improving the flavor reproduction and aroma harmony of coffee, reducing production costs, avoiding solvent residues and oxidation of heat-sensitive substances, and making it suitable for industrial applications.

Abstract

This invention belongs to the field of atomization technology, specifically relating to a coffee extract, an atomizing matrix, and an electronic atomization device. The coffee extract provided by this invention, by mass fraction, comprises 350-450 parts furfuryl alcohol, 5-10 parts furfuryl formate, 2-5 parts 2-acetylfuran, 5-10 parts 5-methylfurfural, 20-30 parts furfuryl acetate, 10-20 parts guaiacol, 30-40 parts maltol, 5-15 parts 4-ethylguaiacol, 5-15 parts difurfuryl ether, and 10-20 parts 4-vinylguaiacol. The coffee extract provided by this invention has a low caffeine content but a strong characteristic coffee aroma; when applied to an atomizing matrix, it can enhance the taste and inhalation experience of the aerosol.
