OEM for new raw material extracts

Development of new extracts

We utilize the supercritical carbon dioxide (CO2) extraction method to develop new raw materials from the extracts and create new business opportunities.

Supercritical CO2 extraction makes it possible to obtain new extracts that are hard to be extracted with water.
We entirely support the development of product using the data and know‐how accumulated from the founding of the company in 1900 to the present day.

Merits of supercritical carbon dioxide (CO2)extraction
Fat-soluble ingredients (oils and fats, pigment) are usually extracted with organic solvents (hexane, etc.), but the organic solvents remain in the extract, which is considered as a problem. Carbon dioxide is harmless to the human body and can be used as a substitute for the organic extraction solvent. In addition, as the extraction process is performed under an oxygen-free environment with no light, there is no need to worry about oxidation or photolysis of the ingredients.

What is supercritical CO2 extraction?

It is an extraction process that uses a CO2 fluid that is beyond the limit (critical point) of temperature and pressure in which gas and liquid can coexist, and has a gas property (diffusion property) of being able to enter anywhere and also a liquid property (solubility) that dissolves ingredients.

Range of techniques using supercritical fluid: In the supercritical area of carbon dioxide, ingredients that are easily oxidized or are weak to high temperatures such as hot water can be extracted, so there are more extractable ranges with increased added value of the raw material obtained.

Development of new raw materials from extracts and the flow of OEM

  • 1Client meeting
    Confirmation of the need for manufacture of product and discussion on the natural product to be extracted per client’s request.
  • 2Trial production
    Trial extraction is conducted using the natural product in question. When using the supercritical CO2 extraction method, we conduct an extraction test using a trial machine that is 1/1000 the size of the actual production machine.
  • 3Evaluation
    Extracted ingredients obtained from the trial extraction are analyzed and evaluated.
  • 4Discussion for
    actual production
    If the sample extract obtained reaches a high enough level in terms of quality and ingredients, we calculate the cost of actual production and perform a scale-up test using an actual production machine.
  • 5Manufacturing
    We determine the extraction conditions based on the result of the scale-up test and manufacture the product
  • 6Delivery of the product
