Problems solved by technology

Supercritical CO 2 As a green and environmentally friendly technical means, it has been applied to remove caffeine in tea. However, supercritical CO 2 While extracting the caffeine in the tea leaves, the aroma components in the tea leaves are also extracted, resulting in a lighter aroma and a stronger sour taste from the original bitter taste, which is difficult to be welcomed by consumers.
