Definitions

  • the present invention relates to a process for the extraction of fats and oils from natural substances, such as e.g. Vegetable, animal or microbial raw materials, with the help of liquid propane as a solvent, this process for the production of fats and oils as well as for the production of degreased or de-oiled products, which are becoming increasingly important as low-fat and thus low-calorie products in the food sector. is applicable.
  • natural substances such as e.g. Vegetable, animal or microbial raw materials
  • a disadvantage of conventional solvent extraction is the fact that most solvents are not toxicologically safe and that the extracted fats and oils and the extraction residues must be largely solvent-free before they can be used for food or feed purposes. This requires comparatively high temperatures, which can negatively affect the sensory properties of the products.
  • the separation For the degreasing of animal raw materials, such as fatty meat, the separation has the largest technical Meaning.
  • the difference in density of meat and fat components is usually used after thermal or mechanical digestion of the starting material in order to carry out a separation in separators or decanters.
  • this process cannot produce fatty meat products with a fat content lower than 10%, otherwise the loss of meat is too high.
  • extractive processes must be used, which have the disadvantages already mentioned in the case of the use of organic solvents.
  • the present invention was therefore based on the object of developing a process for the extraction of fats and oils from natural substances with the aid of propane as a solvent, which does not have the disadvantages of the prior art mentioned and which, without great technical outlay, has both sufficient gas loading with fats and oils as well as a good sensory quality of the products.
  • all fat-containing or oil-containing natural substances based on plants, animals or microbes can be used for the process according to the invention.
  • vegetable fats or oils are olive oil, palm oil, bamboo fat, coconut fat, cocoa butter, coffee oils, peanut butter, rapeseed oil (rapeseed oil), flax oil (linseed oil), sunflower oil, wheat germ oil, rice germ oil, cottonseed oil, corn germ oil, soybean oil, palm kernel oil and pumpkin seed oil.
  • beef or veal and marine oils such as e.g. Fish oils in question.
  • the method according to the invention can also be used for fermentation residues, for example from yeasts, fungi or bacteria.
  • the extraction material in comminuted, pelletized form.
  • the (in particular solid) starting material have a have a high water content, such as meat or fermentation residues, it has proven to be particularly advantageous to reduce the moisture to below 50% by suitable drying methods before the extraction.
  • the extraction with liquid propane is carried out in a very narrow and defined pressure and temperature range which is 10 to 30 bar or 10 to 55 ° C.
  • the process is preferably carried out at an extraction pressure of 15 to 25 bar and an extraction temperature of 20 to 45 ° C.
  • the extraction pressure and temperature must be coordinated so that the propane is in a liquid state.
  • the amount of propane gas used can be varied within wide limits and depends essentially on the amount of oil or fat to be extracted. Depending on the type of raw material, 2.5 to 500 g of liquid propane are normally required per g of fat or oil to be extracted. The maximum gas loading with lipid substances under these extraction conditions is 5 to 25% by weight, depending on the type of fat or oil extracted.
  • the purity of the propane gas used is relatively uncritical in most cases, i.e. noticeable amounts of impurities from homologous hydrocarbons (due to the refining process) can also be present without any noticeable loss in quality.
  • Propane is preferably used in technical purity of approx. 90% and in deodorized form.
  • the extraction with liquid propane can in some cases also be carried out in two or more stages in order to obtain the fats or oils completely.
  • the propane gas is preferably circulated in order to be able to load the desired lipid substances several times, but it is also possible to contact the extraction material only once with the extraction medium.
  • several extraction autoclaves can be connected in series and the extraction medium can be flowed through in succession.
  • the maximum achievable gas load of the liquid propane can always be optimally used by suitably switching the sequence of these autoclaves (e.g. flow through according to the advanced degree of extraction).
  • fats and oils dissolved in the liquid propane are separated by reducing the pressure and / or increasing the temperature, a reduction in pressure and an increase in temperature to 80 80 ° C. having proven particularly advantageous. In this way it is ensured that no undesired reactions such as isomerization of the double bonds of polyunsaturated fatty acids take place during the deposition.
  • the deposition is carried out by isobaric evaporation of the solvent, as a result of which the economy of the process can be increased significantly.
