Problems solved by technology

[0003] However, the gardenia oil prepared by the traditional pressing method has darker color, more impurities, lower content of crocin-I, and lower extraction rate of gardenia oil
When a single subcritical extraction technology is used to extract gardenia oil, the subcritical extraction process is an intermittent extraction, which requires a lot of manpower and material resources to complete multiple extraction processes. The extraction efficiency is low, and the extraction time is too long, which may easily lead to solvent residues.

Abstract

The invention discloses gardenia oil rich in crocin-I as well as a preparation method and application of the gardenia oil. The preparation method comprises the following steps: carrying out high-pressure pretreatment on dried gardenia fruits and a subcritical fluid at 300-500MPa, then carrying out subcritical extraction to obtain gardenia oil, and further refining the gardenia oil to obtain the final gardenia oil rich in crocin-I, wherein the water content of the dried gardenia fruits is 7-10%, and the dried gardenia fruits are subjected to crushing treatment before being subjected to high-pressure pretreatment at 300-500 MPa. The gardenia oil has high yield, the extracted gardenia oil has high crocin-I content, the prepared capsule has high gel strength and tensile strength and high elongation at break, and thermal stability and storage stability of active ingredients such as crocin-I are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soft capsules, and in particular relates to a gardenia oil rich in crocin-I and a preparation method and application thereof. Background technique [0002] Gardenia mainly has two major components: fruit oil and pigment. The fruit oil content reaches 16% to 20%. It is rich in unsaturated fatty acids and biologically active substances such as sterols, vitamin E, squalene and crocin-I. It has anti-inflammatory properties. Antipyretic, immune regulation, anti-cancer, qi-regulating and pain-relieving, cell repair, anti-oxidation, anti-inflammatory and sterilization and other pharmacological values ​​can be developed and utilized as a new oil source. Crocoside-I is a kind of natural pigment in gardenia. The natural pigment is non-toxic and has no side effects. It also has pharmacological effects such as anti-cancer and anti-tumor, preventing atherosclerosis, protecting the liver and promoting gallbladder. It i...
