How to Make Grapefruit Seed Extract

Updated April 17, 2017

Grapefruit seed extract is a popular natural remedy for many ailments, including skin conditions like eczema and psoriasis. Grapefruit seed extract is generally commercially manufactured. The process of making grapefruit seed extract is fairly difficult, and includes a series of chemical and heat treatments to safely isolate the grapefruit seed extract for household use. To prepare the grapefruit seeds for extraction, some strong chemicals are required, and the process should be done in a safe lab by an experienced chemist, and should not be done at home. The following article outlines the steps necessary to commercially extract grapefruit seed extract.

  1. Grind the grapefruit seeds into a fine powder.

  2. The powder is dissolved into pure water to remove the bulk of the grapefruit seed, which includes fibre and pectin.

  3. The mixture is then spray dried at a low temperature to form a grapefruit seed concentrate powder.

  4. The grapefruit seed concentrate powder is then prepared by dissolving it in vegetable glycerine and heating it up. Vegetable glycerine is comprised of natural plant oils that have been treated until the fats change into glycerine.

  5. Natural acidic substances are added to the mixture. These can include ascorbic acid and other types of food-safe acids.

  6. At this point, the mixture is heated under pressure to catalyse the mixture.

  7. Cool the mixture.

  8. Filter the mixture.

  9. The product is then treated with ultraviolet light, which slows down the breakdown of the product by affecting the enzymes.

  10. Tip

    Grapefruit seed extract can be obtained safely and over the counter at most grocery stores and natural food stores.


    The process of obtaining grapefruit seed extract from the grapefruit seed involves dangerous chemicals, and should not be attempted at home. These instructions are for chemists who have training on how to handle the dangerous acids and enzymes involved in the grapefruit seed extracting process.
