Evolution of temporal dynamic of volatile organic compounds (VOCs) and odors of hemp stem during field retting

New non-destructive approach to evaluate the retting process was investigated. Increase of retting duration led to a decrease of VOCs emitted by plants and change of color and plant odor. The variation of VOCs and odor could be used as indicators for the degree of retting. In the hemp industry, retting is an upstream bioprocessing applied to the plants to facilitate the decortication of fibres from the central woody part of the stem.

New non-destructive approach to evaluate the retting process was investigated. Increase of retting duration led to a decrease of VOCs emitted by plants and change of color and plant odor. The variation of VOCs and odor could be used as indicators for the degree of retting. In the hemp industry, retting is an upstream bioprocessing applied to the plants to facilitate the decortication of fibres from the central woody part of the stem. This treatment is currently carried out in an empirical way on the ground which leads to variability in the hemp stems quality, and thus to the hemp fibres quality. Therefore, controlling retting treatment is a crucial step for high-performance hemp fibre. In this study, a new approach is used to assess the retting degree by following the evolution of VOCs emitted by plants during different retting durations. Either harvest time or retting induces a change in VOCs released by plants. During plant maturity, volatile compounds emitted decreased with a factor of about 2, in relation to VOCs released at the end of flowering. Regardless of the harvest period, the majority of VOCs and odor concentrations, monitored by olfactometric analysis, decrease gradually until some of them disappear at the end of retting. Likewise, the green plant odor disappears during retting with an increase of dry plants odor and an appearance of fermented odor at the end of retting. Following the evolution of VOCs emitted by plants during retting could be a tool for farmers to improve the retting management.

Looking for something to help with my…everything

Republished by Plato

I have a laundry list of conditions, both physical and mental. I am looking at a few different types of CBD, namely vape juices and flowers. I am looking for strains that help with anxiety, depression, insomnia, PTSD, mood swings, and nerve and joint pain. I take medication for all of these things, but these conditions still plague my life. Are there any specific strains or flowers I should be looking at?

Recipes for making CBD Flower into gummies?

Republished by Plato

My wife uses the CBD flower and I was thinking about making her flower into gummies. A friend of her gave her 2 ounces of flower, but that’s way too much for her to use before it goes bad. I tried googling some stuff but it’s all pretty confusing and it was like factory production of CBD. Any info this group may have will be very helpful!
