However, it will take time, after that date, before new cannabis products become available for purchase. Adult consumers can expect new products to appear gradually in physical and online stores beginning in mid-December 2019. For an overview of these new rules, please review\u00a0Final Regulations: Edible Cannabis, Cannabis Extracts, Cannabis Topicals. The Cannabis Act is the law that legalized\u00a0recreational cannabis\u00a0use nationwide in Canada. The\u00a0<i>Act<\/i>\u00a0was passed by the\u00a0House of Commons of Canada\u00a0in late November 2017.<\/p>\n<p>As the regulatory considerations and opportunities in the Canadian cannabis industry continue to evolve, information becomes a crucial commodity to better understand the situation, help make better decisions and increase the probability of success in the industry. With these three new classifications, particularly cannabis extracts and cannabis topicals, there comes a need to better understand the scientific technique of extraction <em>(as well as distillation)<\/em> because extraction is crucial to quality production.<\/p>\n<h2>What is botanical (or cannabis) extraction?<\/h2>\n<p>An extraction is a process of removing the desired chemical components from material to separate it from its initial source. For botanicals, many different parts of the plant can be used, such as the stem, root, flower, or fruit. The result is an oil extract that contains the compounds of interest without the solid plant material. For example, a cannabis extraction can separate the following elements of the plant:<\/p>\n<ul>\n<li>THC (psychoactive ingredient \u2013 tetrahydrocannabinol)<\/li>\n<li>Terpenes (flavor \/ medical benefits)<\/li>\n<li>CBD (medical benefits \u2013 cannabidiol)<\/li>\n<\/ul>\n<p>Botanical extraction can be achieved in roughly 5 to 6 steps depending on the method. There are currently three different methods that are popular for <a title=\"3 Extraction Methods\" href=\"\/plant-botanical-extraction-methods\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">cannabis and essential oil extraction<\/a>.<\/p>\n<h2>Cannabis extraction: three main methodologies<\/h2>\n<ul>\n<li>Super Critical Fluid CO<sub>2<\/sub> Extraction (requires recirculating chillers &lt; -60\u00b0C)<\/li>\n<li>Ethanol (EtOH) Extraction (Requires chillers, rotary evaporator and vacuum pump<\/li>\n<li>Liquid Butane (BHO) or Propane Extraction (usually requires heating circulators, chillers or low temp circulators)<\/li>\n<\/ul>\n<p>All three methods yield extracts with plant lipids and waxes. These extracts require an additional process called\u00a0Winterization\u00a0to remove unwanted components.<\/p>\n<h2>Common terms used in extraction<\/h2>\n<p><strong>Grinding<\/strong>\u2013 This can be performed on any part of the plant, including the flower, stem, or root. Finely grinding the material creates more surface area for the solvent to interact with, leading to much more efficient removal of the chemicals of interest. Grinding is typically performed in a laboratory\u00a0mill, utilizing a blade or grinding balls to reduce the plant into fine particles.<\/p>\n<p><strong>Extraction<\/strong>\u2013 This process places a solid in a solvent in order to remove soluble components. In most cases, high proof ethanol is used for plant extraction. For cannabis, this process will remove Terpenes, THC and CBD oil, leaving a mixture of the desired chemicals and solvent. The solvent will later be burned off using a <a title=\"Tankless Evaporator Systems\" href=\"\/p\/ecodyst-ecochyll-x7-tankless-evaporator-systems\/73116\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">rotary evaporator <\/a>or a <a title=\"Vacuum Purge Oven Bundles\" href=\"\/p\/cascade-sciences-vacuum-purge-oven-bundles\/73123\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">purge oven<\/a>.<\/p>\n<p><strong><a title=\"Winterization Steps\" href=\"\/tech-article\/dewaxing-oil-winterization-steps\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">Winterization<\/a><\/strong>\u2013 This process removes fats, plant lipids, or any kind of wax from the extract. Achieved by adding ethanol to the extract using a simple filtration step requiring only a vacuum pump, B\u00fcchner funnel, filter paper, and vacuum flask. After the material has been filtered, a solution of solvent and extract remains. Use a rotary evaporator to boil off the ethanol, leaving a pure extract that can be dried in a lab oven or readily infused.<\/p>\n<p><strong>Decarboxylation<\/strong>\u2013 This process is necessary to activate the psychoactive effects of the cannabinoids present in the cannabis plant or oil. Decarboxylation has a few different meanings however, in this instance, it means replacement of a carboxyl group (-COOH) with a hydrogen atom and releasing carbon dioxide creating THC from THCA. This is achieved by heating the extract or plant material.<\/p>\n<p><strong>Distillation\/Isolation\/Final Processing<\/strong>\u2013 This process is not required for infusion or oil use but distillation remains an important step in the research process. By heating the extract at different temperatures, each chemical of the plant extract can be isolated. This is useful to recover CBD oil without THC present and in for any research process where a scientist is looking to study a specific compound of the plant.<\/p>\n<p>For more information about how Cole-Parmer can help you \u201cOptimize Your Workflow for Success\u201d, see our <a title=\"Botanicals\" href=\"\/industry\/botanicals\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">botanicals resource page<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Matteo Zonta,\u00a0Chef\u00a0r\u00e9gional des ventes, Canada, Regional Sales Leader, Canada Two main set of regulations make up the Cannabis Act as outlined by the Government of Canada\u2014cannabis regulations and industrial hemp regulations As of October&#8230;<\/p>\n","protected":false},"author":20,"featured_media":11809,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1979,12,13,14,1964],"tags":[],"class_list":["post-10521","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chromatography","category-food-beverage","category-for-the-lab","category-helpful-technical-info","category-pcr"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Canada&#039;s Regulations for Edibles, Extracts and Topicals | Cole-Parmer Blog<\/title>\n<meta name=\"description\" content=\"With the amended regulations of The\u00a0Cannabis Act, effective October 17, 2019, come a need to better understand the scientific technique of extraction.
