Description of Glyceryl trileate  :

Chemical property

Triolein is an ester compound with ester's basic chemical properties. Under the action of acid, base, or esterase, triglycerides can undergo hydrolysis to produce glycerol and fatty acids. In addition, glycerol trioleate can undergo alcoholysis, ammonolysis, transesterification and other reactions.

Physical property

The physical properties of triglyceride include its appearance, melting point, boiling point, density, refractive index, etc. Triolein is generally a light yellow to yellow viscous liquid with a unique fat flavor. The composition and structure of fatty acids greatly affect their melting and boiling points.


The stability of triglyceride is mainly affected by temperature, oxygen, ultraviolet and other factors. At high temperatures and in the presence of oxygen, triglycerides are prone to oxidation, resulting in peroxides, free radicals, and the deterioration of oils and fats. To improve the stability of triglyceride, measures such as adding antioxidants, reducing storage temperature and avoiding light can be taken.

Nutritive property

Triglyceride is an important nutrient and one of the sources of fatty acids the human body needs. The human body cannot synthesize triglycerides by itself, and needs to be taken from food. Triglycerides provide energy for the body and are involved in forming and maintaining cell membranes. 

Physiological function

Triglyceride has important physiological functions in the human body. First, it is an important energy source for the human body. When the body ingests triglycerides, it can release stored energy for the body to use after digestion and absorption. In addition, triglycerides are also involved in human metabolism and signal transduction processes.


Under normal use, triglycerides are safe. However, excessive intake of triglycerides can lead to obesity, cardiovascular disease and other health problems. Therefore, the intake of triolein in the diet should be controlled reasonably. In addition, some people, such as patients with severe liver disease or digestive diseases, should be cautious about taking triglycerides or consult a doctor for advice.

Applications of Glyceryl trileate  :

Food industry

In the food industry, triglycerides are mainly used in the processing and production of edible oils. It can provide good taste and stability and extend the shelf life of food. In addition, triglycerides can also be used as food additives, such as shortening, chocolate, ice cream, etc., to improve the texture and taste of food.

Cosmetics industry

In cosmetics, triglycerides are mainly used to formulate skincare and beauty products. Due to its excellent moisturizing and soothing properties, triglycerides can help improve the skin's water balance and texture, making it smoother and more delicate. In addition, it can also be used as an ingredient in cosmetics such as sunscreen and lip balm to provide moisturizing and protective effects.

Pharmaceutical industry

In the pharmaceutical industry, triglycerides have many applications. First, it can be used as a carrier of drugs to help drugs better penetrate the skin or tissues and improve the efficacy of drugs. Secondly, triglycerides can also be used as raw materials or intermediates for synthesizing specific drugs or drug analogs. In addition, some studies have shown that triglycerides have anti-inflammatory, antioxidant, and anticancer biological activities and can be used to treat certain diseases or as an ingredient in functional foods.

Industrial field

In the industrial field, triglyceride has a wide range of applications. For example, it can be used as a lubricant, plasticizer, fuel additive, etc., for producing and processing machinery, electronics, aerospace and other industries. In addition, because of its good chemical stability and oxidation resistance, it can be used to manufacture coatings, paints and other products.

Other fields

In addition to the above fields, triglycerides can be used in other fields. For example, it can be used as a solvent or thinner in paints and coatings' dilution and blending process. In addition, because of its good chemical reactivity, it can synthesize some special functional or polymer materials.

Production Method of Glyceryl trileate  :

Chemical synthesis

Chemical synthesis is a method of synthesizing triglycerides by chemical reaction. This method usually uses glycerin and oleic acid as raw materials and carries out an esterification reaction under the action of a catalyst. In the reaction process, it is necessary to control the reaction temperature, pressure reaction time and other parameters to ensure the product's reaction and quality. The chemical synthesis method has the advantages of fast reaction speed and high product purity. Still, it requires using catalysts and high temperature and high-pressure conditions, and the equipment and operation costs are high.

In recent years, people have also developed an enzymatic synthesis method using lipase to catalyze the esterification of glycerol and oleic acid. Enzyme-catalyzed synthesis has the advantages of mild reaction conditions, easy catalyst recovery, and environmental protection and has gradually become a research hotspot in triglyceride production.

Extraction method

The extraction method is extracting glycerol trioleate from natural vegetable oil. This method usually uses an organic solvent to extract the triglyceride from the vegetable oil and then purification by distillation, crystallization, and other steps. The extraction method has the advantages of a wide source of raw materials and a simple production process. Still, it needs to use a lot of organic solvents, and there are some problems, such as environmental pollution and solvent residue.

People have also developed supercritical fluid extraction methods to overcome the shortcomings of extraction methods. This method uses supercritical fluids (such as carbon dioxide) to extract vegetable oils, which can achieve efficient extraction at lower temperatures and pressures while avoiding using organic solvents.

Biological fermentation

Biological fermentation is a method of producing triolein by microbial fermentation. The method uses oil-rich microorganisms (such as yeast, mold, etc.) as fermentation strains. Fermentation culture is carried out under suitable fermentation conditions, and then the triolein is obtained through extraction, separation, and other steps. Biological fermentation has the advantages of a wide source of raw materials and environmental protection. Still, the problems of a long fermentation cycle and low product content limit its industrial application.

People have also developed genetic engineering bacteria fermentation methods to improve the production efficiency of biological fermentation. In this method, the microbe is genetically modified by genetic engineering technology to synthesize triglyceride efficiently.
