  2. Coconut oil - Wikipedia

    en.wikipedia.org/wiki/Coconut_oil

    Coconut oil is an important base ingredient for the manufacturing of soap. Soap made with coconut oil tends to be hard, though it retains more water than soap made with other oils and thus increases manufacturer yields. It is more soluble in hard water and salt water than other soaps allowing it to lather more easily. [81]

  3. Expeller pressing - Wikipedia

    en.wikipedia.org/wiki/Expeller_pressing

    Expeller pressing (also called oil pressing) is a mechanical method for extracting oil from raw materials. The raw materials are squeezed under high pressure in a single step. When used for the extraction of food oils, typical raw materials are nuts, seeds and algae, which are supplied to the press in a continuous feed. As the raw material is ...

  4. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    Design and operation of a distillation column depends on the feed and desired products. Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method [4] [6] [7] or the Fenske equation [4] can be used. For a multi-component feed, simulation models are used both for design and operation.

  5. Soxhlet extractor - Wikipedia

    en.wikipedia.org/wiki/Soxhlet_extractor

    After many cycles the desired compound is concentrated in the distillation flask. The advantage of this system is that instead of many portions of warm solvent being passed through the sample, just one batch of solvent is recycled. After extraction the solvent is removed, typically by means of a rotary evaporator, yielding the extracted ...

  6. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation is also used for culinary purposes, as coconut oil, palm oil, and palm kernel oil are fractionated to produce oils of different viscosities, that may be used for different purposes. These oils typically use fractional crystallization (separation by solubility at temperatures) for the separation process instead of distillation.

  7. Copra - Wikipedia

    en.wikipedia.org/wiki/Copra

    Copra has traditionally been grated and ground, then boiled in water to extract coconut oil. It was used by Pacific island cultures and became a valuable commercial product for merchants in the South Seas and South Asia in the 1860s. Nowadays, coconut oil (70%) is extracted by crushing copra; the by-product is known as copra cake or copra meal ...

  8. Extractive distillation - Wikipedia

    en.wikipedia.org/wiki/Extractive_distillation

    Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity. Such mixtures cannot be separated by simple ...

  9. Fragrance extraction - Wikipedia

    en.wikipedia.org/wiki/Fragrance_extraction

    Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. [1] The results of the extracts are either essential oils , absolutes , concretes , or butters , depending on the amount of waxes in the extracted product.
