Development Of Supercritical Extraction Technology For Papaya Seeds

Recently, BIT Laboratory has completed the research and development support task for a project of a university in the south: research on supercritical extraction technology of papaya seed oil.

Supercritical CO2 Extraction Equipment for Papaya Seed Oil


Papaya is also known as papaya, pumpkin, milkmelon, tree winter melon and longevity fruit.

It is widely planted in Guangdong, Guangxi, Hainan, Yunnan and Fujian provinces. Papaya is not only a fresh fruit, but also a large number of processed beverages, enzymes, juices and jams and other products. Papaya seed is the waste material of papaya pulp processing, accounting for about 7% of the weight of papaya.

Papaya seed oil is a kind of monounsaturated fatty acid oil mainly composed of oleic acid, which is very similar to olive oil, but has obvious differences with other vegetable oils (such as peanut oil, rapeseed oil, etc.). Oleic acid plays a special role in lipid metabolism. It can not only reduce harmful cholesterol (LDL), but also maintain the level of beneficial cholesterol (HDL), thus slowing down atherosclerosis and effectively prevent cardiovascular diseases such as coronary heart disease. High oleic acid content is conducive to prolonging the shelf life of oils and products. Nutrition makes oleic acid a “safe fatty acid”.

The oleic acid content of papaya seed oil is as high as 68.42%. Therefore, the development of papaya seed oil as a food or health product oil will be very beneficial to the human body.

Compared with traditional extraction and separation technology, supercritical extraction has unique advantages such as low temperature, effective retention of biological activity, good product quality, etc.

Therefore, the application of supercritical extraction technology in papaya seed extraction, if successful, will have rich product development possibilities and market application prospects.

Extraction experiment

The goal and technical difficulty of the research and development support provided by BIT Laboratory for a project team of Southern University is to find a suitable supercritical extraction process route and operation parameters, so as to achieve a higher extraction rate while taking into account the quality of the extracted product oil, so as to minimize the number of the whole extraction process of papaya seeds, save production time, and as far as possible. Reduce the equipment investment and production cost of enterprises in the future.

Through many days of in-depth research and experimental verification, BIT Lab successfully found the determinants and changing rules to ensure the quality and improve the yield of papaya seeds as much as possible, and successfully completed the technical development work. Samples and research and development reports have been delivered to the project team of the University today for the follow-up research and development work.
