VarTech International Co. proposes to cooperate in establishing a plant in Estonia in order to produce bio-active products from wastes of Siberian larch in the frames of above mentioned project.
«Production of Dihydroquercetin (DHQ) from Larch Timber» Supplemental to factors otherwise crucial
for physical health of man (habitat, nutrition, immune system),
active antioxidants hold a prominent place. A complete cycle of
research into therapeutic value of antioxidants was elaborated
and approved as early as in 1950. Thereafter DHQ (taxifolin) was
acknowledged as the most important Š-vitamin, providing for life
activity of man. It has been established with certainty that Š-vitamins are responsible for the capacity to resist pathologies and viral diseases of various living organisms. Introduction of DHQ into the food ration of animals, fowl, and fish significantly reduces the rate of contagious diseases, afflicting them. But what is even more important – it contributes to supply of ecologically clean and harmless food, in the form of animal protein, fats, and vitamins. Absence of P-vitamins in the food allowance of cattle for instance may bring about disasters (mad cow disease etc.). In view of outstanding performance of DHQ it has been assigned, as a mandatory component to the menu of people lodged in emergency situations, those engaged in top priority missions, when subjected to high doses of electromagnetic radiation, nuclear radiation, viral infection, physical overload. DHQ may also be used in wine making industry, for
artificial wine and cognac senescence, and as natural preservative
in food and pharmacological industry, e.g. for increasing the
antioxidant, anti-mould, anti?yeast effect of layered shrink wrapper
plastic, designed for packaging the foodstuffs. In 2000, scientists synthesised, from mono-crystalline product and tested the active forms, suppressing the cancer cells. DHQ does not affect the normal development of living cell, thereby contributing to the development of a range of antibacterial preparations, enabling to protect the living cell of man and animals against different pathologies and viruses, and also free radicals, at the upper limit of regulated norms. DHQ is one of natural Š-vitamins, which cannot be manufactured synthetically. Whereas DHQ is a standard against which the other antioxidants, including synthetic ones, can be measured. Its anti-radical effect is manifested at concentration ca. 10-4 – 10-5% with absolutely no mutagenic impact on man, i.e. with the absence of cytotoxic effect in any concentrations. Still, wider application of DHQ is now impeded by
its prohibitive price – 170-450 US dollars per gram! This is so
due to rare or costly raw material where DHQ is derived (wood
of abies balsamea/tsuga canadensis and Boulogne pine, rose petals,
flowers of Japanese cherry, flowers of grapes), having low antioxidant
content and demanding sophisticated technology for extraction
of highly purified preparation. We have at our disposal a highly efficient technology of extraction of DHQ from astoundingly cheap raw material, namely Siberian larch (Russia). The larch reserves here amount to ca. 60 billion cubic metres.Annual procurement of larch timber is 30 million cubic metres.Waste of raw material of larch (from base of the tree trunk and roots) for further production of DHQ amounts to 3 million cubic metres. Given the minimum DHQ content 2% in the waste of larch, the realistically estimated level of extraction of DHQ from the overall mass of raw material constitutes 1%. This will enable to annually produce 30 thousand tons of DHQ. Research efforts and developments in the area of industrial production of DHQ from larch are protected with patents. Finalised have been bench tests of the pilot-production line for output of 0.3 tons per year.
The stability of business after the production of DHQ is launched, will be guaranteed by the following:
