Pesticide Removal

The industry is moving towards pesticide testing for concentrates. As we know, concentration also concentrates impurities like pesticides. What methods/technology is there to remove them?

  • I also see the term "fractionalizing". What is the meaning, and how do you do it. Is this an answer to my first question?

  • Then if it’s so difficult to eliminate the pesticides , maybe the right question should be , how long before harvesting should pesticides not be used to ensure they will not be present?

    I agree, that's a better question. Or, ideally, making the focus pest-management without pesticides (i.e. beneficial insects).

  • It has been proven that having clean flower does not guarantee clean oil. It’s just the nature of the beast.
    Charcoal filters are less than perfect, and just getting oil to “pass” is not the same as “being clean”.
    Surely the scientific community is working on this???

  • Why not use natural pesticides and stop the problem before it starts?

    Citrus is key

  • It's not that simple. Even flower has some level of pesticides from incidental contact. There are pesticides in everything at some level. Commercial soil, nutrients, and additives all contain some pesticides. When you concentrate that flower the pesticides act erratically and may increase exponentially. That's why 70% of the concentrates out there cannot pass a pesticide test. That is one of the reasons you see very little concentrates with the state medical logo.

  • What's the best method to extract oil (oudh) from agarwood? Traditional method using hydro distillation produces oil with a signature smell that most peole identify with. Will a.change in extraction method f.i. using supercritical CO2 produce oil with a different smell?
