Fine talk about vegetable oil —— Cactus seed oil

History

Most parts of the cactus, whether for external use or internal service, can be beneficial to people or animals, and have been widely used in the world. For example, in traditional medicine, the pear fruit cactus is used to treat burns. The Aztecs extracted the milk from the cactus, and mixed it with honey and egg yolk as an ointment for treating burns. Pear cactus is also used to treat trauma, edema, hyperlipidemia, obesity and catarrhine gastritis. In the traditional Mexican medicine, the roxburgh pear cactus is used to treat diabetes, as well as high cholesterol. Its alcohol extract has been shown to have anti-inflammatory, hypoglycemic, and antiviral effects. The Chinese treat the abscesses with the fleshy stems of the cactus, which the American Indians use the cactus fruit as food, and will also make into serous fluids for pertussis and asthma.

Only recently, studies have begun to indicate the great benefits of cactus fruit seeds on the skin. The edible portion of the cactus fruit grows with many cactus fruit seeds, which can account for 30-40% of the weight of the cactus dried fruit. These seeds contain nutritious oil that can be extracted and used for skin care. Nowadays, the squeezed cactus fruit seed oil is widely used as a medium oil or formula ingredients in cosmetics and skin care products.

Cactus seed oil ingredients

In a 2002 study conducted by Mohamed Fawzy Ramadan and Jorg-Thomas Morsel, the lipid composition of the cactus seed oil was noted as being 98.8g/kg. Lipid composition analysis showed that it is a good linolenoleic acid, oleic acid source, linoleic acid: oleic acid ratio is about 3:1. Linoleic acid is the most dominant fatty acid, followed by palmitic acid, oleic acid. Ramadan and Morsel noted that the amount of total lipids in the cactus seed oil depends on its cultivation method, maturity, and the processing of the fruit, and preservation conditions.

Meanwhile, for lipid-soluble vitamins, Ramadan and Morsel detected 0.04% of vitamin E in cactus seed oil.-Tocopherol is the most dominant existential form of vitamin E, followed by ⍺ -tocopherol. In addition, the proportion of vitamin A present in the form of beta-carotene was about 0.42g / kg. Vitamin K1 represents about 0.05% of the total lipids.

Also, cactus seed oil contains high levels of steroids, about 9.33g / kg.-Glutasterol is a landmark sterol component, representing 72% of the total sterol content, followed by vegetable oil sterol, duosterol, lanosterol, 5-oat sterol, and 7-oat sterol.

The study concluded that cactus seed oil, and cactus fruit meat are a rich source of fatty acids, fat-soluble vitamins and sterols.

In recent years, after the study, many more studies have been conducted to analyze the composition of cactus seed oil, and we refer to compare the data provided by Ramadan and Morsel. In other studies, cactus seed oil was also found to be rich in fatty acids, especially linoleic acid. One of the studies detected 61.4-68.9% linololeic acid, 12.38-16.51% oleic acid, and 11.44-15.89% palmitoleic acid, and also provided data of as high as 70.3%, and subsequently oleic acid, 16.7%. From the proportion of these lipid components, cactus seed oil is very rich in nutrients, comparable to grape seed oil.
