The AOCS Annual Meeting is an international science and business forum on fats, oils, surfactants, lipids and related materials. The American Oil Chemist’s Society (AOCS) is holding their meeting in Orlando, Florida from April 30 to May 3, 2017. Last year’s meeting included discussions on best practices and the pros and cons of different extraction techniques, sample preparation, proficiency testing and method development, among other topic areas.
Posters on display for the duration of the Annual Meeting will discuss innovative solutions to test, preparing samples, discovering new compounds and provide novel information about the compounds found in cannabis. David Egerton, vice president of technical operations at CW Analytical (a cannabis testing laboratory in Oakland, CA), is preparing a poster titled Endogenous Solvents in Cannabis Extracts. His abstract discusses testing regulations focusing on the detection of the presence of solvents, despite the fact that endogenous solvents, like acetone and lower alcohols, can be found in all plant material. His study will demonstrate the prevalence of those compounds in both the plant material and the concentrated oil without those compounds being used in production.
The conference features more than 650 oral and poster presentations within 12 interest areas. This year’s technical program includes two sessions specifically designed to address cannabinoid analytics:
Lab Proficiency Programs and Reference Samples
How do you run a lab proficiency program when you cannot send your samples across state lines? What constituents do you test for when state requirements are all different? Are all pesticides illegal to use on cannabis? What pesticides should be tested for when they are mostly illegal to use? How do you analyze proficiency results when there are no standard methods? Learn about these and other challenges facing the cannabis industry. This session encourages open and active discussion, as the cannabis experts want to hear from you and learn about your experiences.
The need for high-quality and safe products has spurred a new interest in cannabinoid analytics, including sample preparation, pesticide, and other constituent testing. In this session, a diverse group of scientists will discuss developing analytical methods to investigate cannabis. Learn the latest in finding and identifying terpenes, cannabinoids, matrix effects, and even the best practice for dissolving a gummy bear.
Cynthia Ludwig, director of technical services at AOCS, says they are making great progress in assembling analytical methods for the production of the book AOCS Collection of Cannabis Analytical Methods. “We are the leading organization supporting the development of analytical methods in the cannabis industry,” says Ludwig. “Many of the contributors in that collection will be presenting at the AOCS Annual Meeting, highlighting some of the latest advances in analyzing cannabis.” The organization hopes to foster more collaboration among those in the cannabis testing industry.
In addition to oral and poster sessions, the 2017 Annual Meeting will feature daily networking activities, more than 70 international exhibitors, two special sessions, and a Hot Topics Symposia which will address how current, critical issues impact the future of the fats and oils industry.
The CannaGrow Conference & Expo, held in San Diego on May 7th and 8th, educated attendees on the science of cannabis cultivation. The conference brought subject matter experts from around the country to discuss cannabis breeding and genetics, soil science and cultivation facility design.
Discussions at the conference delved deep into the science behind growing while providing some expert advice. Drew Plebani, chief executive officer of Commercial Cultivator, Inc., gave a comprehensive review of soil ecology and how understanding soil fertility is crucial to successfully growing consistent cannabis. “Soil fertility is measured by laboratories in terms of soil minerals, plant-available nutrients, percent of organic materials, pH levels and most importantly the balance of the soil’s chemical makeup,” says Plebani. “There is no silver bullet in soil ecology; increasing your soil fertility comes down to understanding the composition of soil with analytical testing.” Plebani went on to add that soil systems for cannabis need to be slightly fungal-dominant in developing an endomycorrhizal system, which is optimal for cannabis plant growth.
Tom Lauerman, colloquially known as Farmer Tom and founder of Farmer Tom Organics, kicked off the conference with an introduction to cultivation techniques. Lauerman also delved into his experience working with federal agencies in conducting the first ever health hazard evaluation (HHE) for cannabis with the National Institute for Occupational Safety and Health (NIOSH). Through the HHE program, NIOSH responds to requests for evaluations of workplace health hazards, which are then enforced by the Occupational Safety & Health Administration (OSHA). Lauerman worked with those federal agencies, allowing them to tour his cultivation facilities to perform an HHE for cannabis processing worker safety. “I was honored to introduce those federal agencies to cannabis and I think this is a great step toward normalizing cannabis by getting the federal government involved on the ground level,” says Lauerman. Through the presentation, Lauerman emphasized the importance of working with NIOSH and OSHA to show federal agencies how the cannabis production industry emerged from the black market, branding itself with a sense of legitimacy.
Adam Jacques, award-winning cultivator and owner of Grower’s Guild Gardens, discussed his success in breeding CBD-dominant strains and producing customized whole-plant extractions for specific patients’ needs. “I find higher percentages of CBD in plants harvested slightly earlier than you would for a high-THC strain,” says Jacques. “Using closed-loop carbon dioxide extraction equipment, we can use multiple strains to homogenize an oil dialed in for each patient’s specific needs.” As a huge proponent of the Entourage Effect, Jacques stressed the importance of full plant extraction using fractionation with carbon dioxide. He also stressed the importance of analytical testing at every step during processing.
Zacariah Hildenbrand, Ph.D., chief scientific officer at C4 Laboratories, provided the 30,000-foot view of the science behind compounds in cannabis, their interactions and his research. With the help of their DEA license, he started the C4 Cannabinomics Collaborative, where they are working with Dr. Kevin Schug at the University of Texas-Arlington to screen various cannabis strains to discover new molecules and characterize their structure. “Secondarily, we are using gene expression profiles and analysis to understand the human physiological response and the mechanism through which they elicit that response,” says Hildenbrand. “As this research evolves, we should look to epigenetics and understanding how genes are expressed.” His collaborative effort uses Shimadzu’s Vacuum Ultraviolet Spectroscopy (VUV), and they use the only VUV instrument in an academic laboratory in the United States. “Pharmaceuticals are supposed to be a targeted therapy and that is where we need to go with cannabis,” says Hildenbrand. Him and his team at C4 Laboratories want to work on the discovery of new terpenes and analyze their potential benefits, which could be significant research for cannabis medicine.
Other important topics at the conference included facility design and optimization regarding efficient technologies such as LED lighting and integrated pest management.
As the cannabis marketplace grows and more companies gain interest in this space, so does the need for greater access to networking, expert advice and credible information. Events in the form of conferences with educational sessions and expos provide these tools in one location over a span of several days. Many of the conferences include valuable information regarding everything from cultivation to compliance for established marijuana businesses or those seeking to gain entry into the market. Some noteworthy events include:
- Cannabis World Congress & Business Exposition (June 15-17, 2016 in New York City and September 7-9, 2016 in Los Angeles) hosted by the International Cannabis Association.
- Marijuana Business Conference & Expo (November 11-13, Las Vegas) hosted by the Publishers of Marijuana Business Daily
- DispensaryNext Conference & Expo (February 1-2, 2016 in Portland) hosted by CannaConnections.
Earlier this year the CannaGrow Expo, run by CannaConnections, took place in Portland, Oregon. This event combined the intimate setting of a hotel conference with valuable educational opportunities on all things cultivation. With presentations ranging in topics from the fundamentals of growing to integrated pest management and growing organically, this event provided information for everyone along the spectrum, including beginner cultivators entering the space and veteran growers who have run legal operations for years.
“We believe in great attendee experiences, which starts with a great education,” says Joseph De Palma, founder at CannaConnections. “This is not a festival or mega-expo; this is an educational conference for professionals. Our agenda is designed around providing attendees with actionable, non-salesy cultivation education.”
Clark Tippin, founder of the Organic Cannabis Growers Society, gave a noteworthy presentation called Growing Organically – Sustainable Practices & High Yields, which highlighted the benefits and technical details of various organic cultivation methods.
“Cannabis is a non-homogenous plant that requires extremely consistent and standardized conditions with good production techniques in order to homogenize CBD levels and terpene profiles,” said Autumn Karcey, CEO of CannaVize, Inc., a sustainable full-service consulting and design firm, during her presentation, Commercial Facility Optimization for Pharmaceutical Grade Cannabis. “The consistency of cannabis comes from maintaining these standardized conditions through good manufacturing practices, quality assurance practices and standard operating procedures.”
CannaConnections’ next scheduled event is the DispensaryNext Conference & Expo, which runs February 1-2, 2016 in Portland. The range of topics includes best practices, marketing strategies, and operational management for dispensary owners and managers.
