Supercritical Fluid Extraction And Separation Process Of Moringa 3 Major Components


Moringa originated from the southern foothills of the Himalayas in northwestern India. It is the oldest medicinal and edible tree species for mankind. It is rich in protein, vitamins, amino acids and minerals such as calcium, iron, phosphorus, and potassium.

According to the test of the Vegetable Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture of China, the protein in every 100g of Moringa is about twice that of milk, VC is about 7 times that of fresh orange, VA is about 4 times that of carrots, and iron is about 3 times that of spinach. Calcium is about 4 times that of milk, and potassium is about 3 times that of bananas. The whole plant is available, and the nutrients are very rich and complete. The roots, stems, leaves, and fruits are all raw materials for medicine and are widely used in the international market. Exploited and utilized, it has been called an “incredible tree” in Japan.

Known as “vegetarian gold” in India, Africa and other places, it has high application value. Moringa has become a highly regarded health food in the industry and is known as the “Diamond in the Plant”. It was listed as a new resource food in China in 2012.

Moringa seeds are pure natural green food, containing all the nutrients needed by the human body.

It can replace multi-vitamins, calcium tablets, cod liver oil, etc., to help improve and prevent diseases, improve sleep, enhance immunity, and delay aging. Moringa seeds have strong antihypertensive, lowering blood fat, lowering blood sugar, and anti-cancer effects. It is used for medicinal purposes. And the health effect is extremely high.

The seed kernel of Moringa seeds is used as a Chinese herbal medicine in the folk, which can be used to prevent cancer and cardiovascular diseases. Because it is rich in Moringa oil, Moringa seeds have some better performance in detoxification and acceleration of metabolism.

It can also be used to treat diseases of the liver, spleen, meridians and other special parts. It also has the effects of curing bad breath and sobering alcohol. In general, Moringa seeds have significant effects on lowering blood lipids, blood pressure, weight loss, regulating the intestines and stomach, protecting the liver and abstaining from alcohol, and enhancing human immunity.

There is no evidence that Moringa seeds have the function of improving male reproductive capacity claimed by some businesses in the market.

In addition, Moringa seeds have an excellent water purification effect. The vegetable protein contained in it is a natural coagulant, which can effectively remove turbidity in the water, and also has a good removal effect on microorganisms and heavy metals in the water.

Moringa seeds contain active ingredients with excellent flocculation components. The water extract of the seeds can significantly reduce the turbidity, hardness and bacterial content of the mixed water.

One can find the record of Moringa as a water purifier in the Bible: “Moses called to the Lord, and the Lord directed him to a tree. He threw the tree (moringa) in the water and the water became sweet.”

Moringa seed oil extraction method

Moringa seed oil can be extracted by pressing method, solvent method, pressing-solvent method, ultrasonic-solvent method.

The residual oil content of the cake is high by the pressing method; although the oil yield is high by the solvent method, the oil has a deep color; the degreasing by the pressing-solvent method or the ultrasonic-solvent method can reduce the cost and increase the oil yield, but it still needs to be carried out. Desolvation and refining treatment.

Supercritical CO2 Extraction of Moringa Seed Oil

Supercritical CO2 extraction process may be the best method for extracting Moringa seed oil. We conducted experiments on the effects of extraction pressure, extraction temperature, extraction time, and CO2 flow rate for supercritical CO2 extraction of Moringa seed oil to screen the process parameters.

Moringa seeds → natural drying → crushing → weighing → filling in the kettle → SFE-CO2 → separation → Moringa seed oil

The extraction temperature is 50℃, the extraction pressure is 30M Pa, the extraction time is 3h, and the CO2 flow rate is 23L/h. The extraction effect is the best.

Using SFE-CO2 to extract Moringa seed oil, not only the process is simple, the oil has a clear appearance, high purity, no solvent residues, high safety, and low peroxide value (0.431m eq/kg, using the GB/T5538-1995 method) Determination).

SFE-CO2 extracts Moringa oleifera seed oil, the defatted meal is rich in flocculating active protein, avoiding the influence of high temperature and solvent residue, it is a high-quality raw material for extracting Moringa oleifera natural flocculant.
