BOREAL FOREST

The biodiversity of the boreal forest in an important source of new therapeutic,  cosmetics, nutraceuticals and technologic sagents. Tree species of the northern boreal forest are sometimes subject to a very aggressive environment; winters where temperatures can drop to -50 degrees C and summers where the heat and humidity are very high. These season to season variations require trees to be highly resistant. To do so, the trees of the northern forest synthesize bioactive molecules of interest. This potential can be valued through the extraction of forest biomass, abundant and renewable resource that is currently used for energy production.

 

WOOD INDUSTRY

The forest industry generates a significant amount of coproducts and at all stages of  wood processing (chips, bark, sawdust, knots, etc.) For instance, bark generated during sawing is mostly burned to produce energy. Sometimes it is even buried, which can cause significant environmental problems.

BARK (BIOMASS)

The bark is a true protective skin of the tree. The tree concentrates in this skin, a panel of bioactive molecules for resisting external aggressions. These natural compounds synthesized in high concentrations in the bark are easily extractable. The extraction of these compounds before energy combustion is therefore an essential step to value forest biomass at its highest potential.

PRETREATMENT OF BARK

The fresh bark of various tree species valued by Bio ForeXtra are collected from sawmills during timber processing. We collaborate with Quebec sawmills that are FSC certified for their ecoresponsible resource exploitation and their forest sustainable management. The bark is then qualified by chromatography to verify its targeted active content. Before extraction, the bark is dried, ground and sifted in order to have a homogeneous material and adapted for efficient extraction.

EXTRACTION

Bio ForeXtra develops its extraction processes at the laboratory scale. Our extraction methods are based on the unique use of green solvents such as water and alcohol or hydroalcoholic mixtures. We work essentially on barks from various tree species used by the traditional wood industry. The extraction methods are intended to enable a high extraction of the family of compounds of interest for personal care. Our expertise is to modulate extraction parameters to obtain concentrated extracts in key active ingredients.

FILTRATION

The filtration step allows separation of the liquid extract and the solid extracted. We use filtering technologies to obtain a clear extract, exempt from any particles.

CONCENTRATION

The concentration consists in largely evaporating solvent to obtain an enriched active liquid. We use vacuum technology which allows working at low evaporating temperatures and thus preserving the full potential of actives that can be temperature sensitive.

DEHYDRATION

Dehydration allows to completely dry the liquid after its concentration and to obtain a powder (native extract). This step is essential for the conception of titrated and standardized extracts.

QUALITY CONTROL

Quality control allows verifying and ensuring the chemical composition of the extract and guarantees standardization of batches. We proceed by chromatographic and spectrophotometric methods of analysis, in order to guarantee our customers the presence of bioactive molecules of interest and key chemical tracers. The high efficacy of our actives is related to the presence of these molecules and the quality of our products by this strict quality control.

FINAL EXTRACT

Our extracts dedicated to the cosmetics market are presented in liquid form in vegetable glycerine. The native extract (powder) is dissolved at a targeted concentration determined according to the active dose of the final extract to be incorporated in the formula of a finished product.
