[0062] Physical indicators

[0063]

[0064] Gardenia Oil Reviews

[0065] Gardenia oil contains more than 65% unsaturated fatty acids, including 42.08% linoleic acid and 17.2% oleic acid, and less than 35% saturated fatty acids. It is especially rich in squalene (1.15% to 1.64%) and has strong antioxidant capacity.

[0066] The physical properties of gardenia oil show that it has low acid value and peroxide value and good stability.

[0067] 2Comparison of index test results between gardenia oil and tea oil

[0068] Table 1 shows the experimental data of gardenia oil obtained by the extraction method of the embodiment of the present invention.

[0069] Table 1 Physical indexes of gardenia oil and ordinary tea oil

[0070] Test items Gardenia Oil tea oil Acid value (mg / g) 2.34 ≦2.50 Iodine value (g / 100g) 86.20 83.22～89.46 Peroxide value (m mol / kg) 10.91 ≦7.50 Saponification value (mg / g) 198.41 193.20～196.62

[0071] It can be seen from Table 1 that the physical indicators of gardenia oil and ordinary tea oil are very similar.

[0072] Table 2 is a comparison of the contents of the gardenia oil obtained by the preparation method of the present invention and common tea oil on the market.

[0073] Table 2 Fatty acids and active substances of gardenia oil and ordinary tea oil

[0074]

[0075] 1. Squalene is not only found in shark liver, but also in the human body. It participates in the biosynthesis of cholesterol and various biochemical reactions in the body, promotes biological oxidation and metabolism, improves the body's defense function, stress resistance and physical and mental quality, accelerates the synthesis of steroid hormones, activates the activity of adenylate cyclase, and causes an increase in the content of cyclic adenosine monophosphate in the second messenger.

[0076] Squalene has biological redox effects and improves energy efficiency, thereby enhancing the body's endurance and improving heart function. After taking squalene, the levels of ceruloplasmin and transferrin, as well as the activities of superoxide dismutase and lactate dehydrogenase, are significantly increased. At the same time, squalene has a function similar to that of red blood cells to absorb oxygen, generating activated squalene oxide, which is transported to the body's terminal cells with the blood to release oxygen, increase the utilization capacity of body tissues, promote liver function and bile secretion, thereby increasing appetite, and has a preventive and therapeutic effect on hypoxic diseases.

[0077] The squalene content in gardenia oil is 100 times higher than that in ordinary tea oil. Therefore, it is superior to ordinary tea oil in improving the immune system, anti-oxidation ability, restoring the normal level of cholesterol in the blood, and fitness and nourishment.

[0078] 2. The effects of flavonoids are multifaceted. It is a very strong antioxidant that can effectively remove oxygen free radicals in the body. For example, anthocyanins and anthocyanins can inhibit the full-stage overflow of oily peroxides. This ability to prevent oxidation is more than ten times that of vitamin E. This antioxidant effect can prevent cell degeneration and aging, and can also prevent the occurrence of cancer. Flavonoids can improve blood circulation and lower cholesterol. These effects greatly reduce the incidence of cardiovascular and cerebrovascular diseases and can also improve the symptoms of cardiovascular and cerebrovascular diseases.

[0079] As described above, the gardenia oil of the present invention is rich in total flavonoids, squalene, crocetin, plant polyphenols and polysaccharides, and is rich in nutrients. Compared with the existing gardenia oil, which has serious nutritional losses and can only be used as ordinary edible oil, the gardenia oil of the present invention can be used as a nutritious food, and long-term use by humans can greatly improve the symptoms of cardiovascular and cerebrovascular diseases and enhance antioxidant capacity.

[0080] The gardenia oil gel candy is prepared by extracting, gelling, pressing and drying gardenia oil, which is convenient for preserving nutrients. The prepared gardenia oil gel candy is rich in active substances squalene and total flavonoids. The squalene content in gardenia oil is 100 times higher than that in common tea oil, and the total flavonoid content is nearly 10 times higher than that in common tea oil. Taking the gardenia oil gel candy of the present invention can significantly improve the immune system and antioxidant capacity, restore the normal level of cholesterol in the blood, greatly reduce the incidence of cardiovascular and cerebrovascular diseases, and significantly improve the symptoms of cardiovascular and cerebrovascular diseases.

[0081] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
