Definitions

  • the invention relates to a device for carrying out a method by means of which a reduction and regulation of the concentration of toxic components in plant parts and a method for reducing and regulating the concentration of toxic components in plant parts can be achieved, and to preparations prepared from the plant parts.
  • Certain plants contain a multitude of different active ingredients as well as fragrance and aroma substances. Some of these substances have a therapeutic or toxic effect on the human body, the concentration being decisive.
  • the dried leaves and inflorescences with stems of the different one or two-house hemp varieties, in particular the different types of cannabis sativa have over 400 substances, for example, the individual effects of which are ultimately not fully known.
  • delta-9-tetrahydrocannabinol is known for its toxic effects on the human body by putting the consumer into a state of intoxication after they have taken up more than a certain minimum amount of this substance.
  • the anticonvulsant and pain-relieving effects of hemp in multiple sclerosis patients who are given the active ingredient with special permission and under medical supervision.
  • the active ingredient Marinol® a synthetic form of delta-9-tetrahydrocannabinol (THC)
  • This active ingredient was first launched in 1987 and used to treat cancer chemotherapy-induced nausea and vomiting. Marinol® was also approved around 1992 for the treatment of appetite loss and weight loss in AIDS patients.
  • Gland resin of the female hemp plant usually has a THC concentration of 1 to 10%, in rare cases up to 20%, hemp varieties with a low THC content still have a content of 0.3% THC (3 g / kg), which is still over 1000 times more than the amount allowed in food. Therefore, commercially available foods with hemp products always contain at most small amounts of hemp, which can cause the taste to be inadequate.
  • Various methods are known that separate THC from hemp. However, the goal of these known methods and processes is the extraction and extraction of THC, with the hemp plant parts becoming a waste product. With these methods, the leaf is destroyed and can no longer be used by a consumer.
  • the dried plant parts are, for example, placed in a water-ice mixture and the THC-containing resin capsules are separated from the plant parts with constant stirring and separated from one another by utilizing the different specific weights.
  • Another method melts the resin from the leaves with the application of heat or gases, other methods use acid for the separation. All of these methods destroy the parts of the plant.
  • parts of plants that have a high concentration of THC are preferably used.
  • Another object of the present invention is to separate the extracted toxic components from impurities and to obtain THC as a substance for a medicament.
  • the object is achieved by a method according to claim 1 and a device according to claim 11 and by a preparation according to claim 19.
  • This process of segregation reduces concentration of the toxic components 33 in the retained preparation 32 to on a toxic harmless and approved for sale Value.
  • the procedure is set by the duration of the procedure so that the concentration of THC in preparation 32 is one Value between 0.1 to 2 mg / kg, preferably between 0.1 to 0.2 mg / kg.
  • An improvement in the process can achieved by cooling the plant parts or the entire system be, preferably to between 0 to -5 ° C. Thereby the THC-containing resin capsules harden and lose on their adherence, which makes them easier to get out of the plant parts let it shake out. Another advantage of Cooling and the reduced adherence of the resin capsules in the reduced contamination of the sieve 13 since the Glue screen openings less quickly.
  • the preparation 32 obtained in this way when poured with hot water, gives an aromatic drink which, in the drinkable preparation, has a THC content which is below the legally permitted limit value of an aromatic drink which is considered toxic and harmless.
  • the advantage of this invention is that this preparation 32 can be consumed immediately and without the addition of other components. The full taste and aroma of the plant used thus come into their own, since the majority of the essential oils are retained in preparation 32.
  • the preparation 32 obtained is also suitable for use as an infusion drink with the addition of other plant parts, for example peppermint or verbena. According to the invention, an admixture of other plant parts of up to 50% is recommended, ideally between 20 to 40%.
  • the preparation 32 obtained with the described method contains a value of THC approved for sale and can therefore also be used as a spice for refining a large number of cold and warm dishes.
  • the seasoning of salads, sandwiches, pizzas, meat, fish, soups and vegetables is particularly popular.
  • the preparation 32 can also be mixed into sweetened, salted or neutral baked goods and baked with them, or prepared ready to eat as a spice or flavoring with other foods.
  • Preparation 32 is particularly suitable as a spice or flavoring for cooking, roasting, steaming, grilling, cooking or marinating.
  • a further possibility of this invention consists in cleaning the contaminated THC, which is collected in the collecting device 16 as screen material 34, from its contaminants, in particular from the dust particles of the rubbed off plant parts, and to a medicament, such as the Marinol® mentioned at the beginning or an equivalent product , to process.
  • the screenings 34 are again placed in a carrier container 12 of the same device 1, the screen 13 now used having a smaller mesh size.
  • they are suitable for sieves from SEFAR® with the designations 54-70W PW or 68-64W PW with nominal mesh sizes of 109 ⁇ m and 78 ⁇ m.
  • the resin capsules containing THC have a typical size of 80 - 150 ⁇ m and thus remain in the carrier container, while the dust particles of the rubbed off plant parts are smaller than 80 ⁇ m and in turn fall through the sieve into the collecting container.
  • This process is also preferably cooled at about 0 to -5 ° C., but for a period of 8 to 12 hours.
  • the other dimensions of the system and the rotational speed of the repeated process remain the same as the first process.
  • This method is based on the same inventive idea of separating the resin capsules 33 from the plant parts by shaking and sieving, preferably at low temperatures.
