Terpenes

Lo Friesen is the founder, CEO, and Chief Extractor of Heylo. With a background in chemistry and clinical research, Lo was inspired to explore cannabis as a medicine and to enter the emerging industry. She joined Eden Labs, a leading CO

 extraction equipment manufacturer to support and expand a Research and Development department. There she managed the development of their latest and greatest CO

 extraction system. In 2017, after working with Eden Labs and another cannabis processor, Lo launched Heylo with a mission to help people get more out of life with cannabis.

In this article, we explore the difference in chemical profile between fresh and dry cannabis flower and why manufacturers may choose to extract frozen or dry cannabis.


The Transformation of Cannabis Terpenes from Harvest to Shelf

In this article, Markus Roggen demonstrates a new method for recapturing terpenes lost during the cannabis extraction process.

Keeping it Clean: Recapturing Terpenes for Added Value and Cleaning Wastewater Streams

Brian C. Smith, PhD, is Founder, CEO, and Chief Technical Officer of Big Sur Scientific. He is the inventor of the BSS series of patented mid-infrared based cannabis analyzers. Dr. Smith has done pioneering research and published numerous peer-reviewed papers on the application of mid-infrared spectroscopy to cannabis analysis, and sits on the editorial board of Cannabis Science and Technology. He has worked as a laboratory director for a cannabis extractor, as an analytical chemist for Waters Associates and PerkinElmer, and as an analytical instrument salesperson. He has more than 30 years of experience in chemical analysis and has written three books on the subject. Dr. Smith earned his PhD on physical chemistry from Dartmouth College.

In part I in a new series of columns, we begin a discussion of the theory of chromatographic separations. Our goal is to derive equations that will help you better perform experiments to optimize your separations.

Principles of Chromatography, Part I: Theory

A review of the claims that differences in extract type can affect cost, ease of formulation, and the experience of the finished product.

Does Extract Type Make  a Difference in Cannabis Edibles?

The various extract types are defined so there can be some consensus once and for all.

Concentrate...What Do You Call It?

Part II of this series reviews the history of vape products, producing cannabis vapes, the myriad of extract types, and how temperature and hardware impact the user experience.


What’s in a Vape? Part II

David Hodes has written for many cannabis publications, and organized or moderated sessions at national and international cannabis trade shows. He was voted the 2018 Journalist of the Year by Americans for Safe Access, the world’s largest medical cannabis advocacy organization.

Different extraction processes, new products, and new equipment combine to create the perfect storm of better, safer extractions.

Taking a Measure of Evolving Extraction Technology

In part one of this two-part series, we review the history of vape products and their obstacles.

What’s in a Vape, Part I

Terpenes can be tricky. Although cannabis is heavily regulated, since cannabis-derived terpenes do not contain tetrahydrocannabinol (THC) and other cannabinoids, they are not regulated in the same way that cannabis is. 

Tricky Terpenes: Under-Regulated Use of Added Terpenes in a Regulated Cannabis Industry
