A process for the separation of a substance from a liquid feed mixture and for the purification of the substance by fractional layer crystallization, wherein the liquid feed mixture comprises the substance to be separated and purified in a concentration of less than 50% by weight, which comprises the subsequent steps in the given order: (a) feeding the liquid feed mixture into a crystallization zone, in which at least one surface is provided, so that at least a part of the surface contacts the liquid feed mixture, (b) cooling the at least one surface of the crystallization zone to a temperature below the equilibrium freezing temperature of the liquid feed mixture so that a crystal layer enriched in the substance to be separated and purified is deposited on the at least one cooled surface, whereby a mother liquid having a lower concentration of the substance to be separated and purified than the liquid feed mixture is formed from the liquid feed mixture, (c) removing at least a portion of the mother liquid from the crystallization zone, (d) adding a further portion of liquid feed mixture into the crystallization zone, (e) allowing further deposition of a crystal layer enriched in the substance to be separated and purified to take place on the at least one cooled surface, (f) optionally carrying out a sweating stage and removing a sweating residue and (g) melting the crystal layer to obtain the separated and purified substance.

Natural 1,2-alkanediols, compositions having natural 1,2-alkanediols and processes for making the same

A process is incorporated herein for the synthesis of bio-1,2-alkanediols, comprising: providing a bio-alkene having a carbon chain of about 5 to about 20 carbon atoms and a bio-1-alkene regioselectivity of at least about 80%, at least about 92% and/or at least about 95%; and converting the bio-alkene to a bio-1,2-alkanediol having a carbon chain length of about 5 to about 20 carbon atoms. Methods for treating catalysts which may be incorporated in the process for the synthesis of bio-1,2-alkanediols are also included herein. Such bio-1,2-alkanediols are used in compositions and products alone as antimicrobial materials, or with existing bio-compounds and/or antimicrobials, preservatives, alternative preservation systems and/or hurdle technology components. The bio-1,2-alkanediols incorporate a natural and bio-based pathway for antimicrobial effects in various compositions such as cosmetic, pharmaceutical, industrial and household products.

Infusing raw cannabinoids into food oil
10981856 · 2021-04-20 ·

A cannabis infused oil is formed by collecting and drying raw cannabis material having a desired cannabinoid profile. Next, the raw dried cannabis material is blended with oil to obtain a cannabis infused oil mixture. Blending is performed without causing the cannabis material to become decarboxylated. Next, the cannabis material is filtered from the cannabis infused oil mixture thereby obtaining a cannabis infused oil. The cannabis infused oil has at least two cannabinoids present in the oil in accordance with the desired cannabinoid profile. Next, the cannabis infused oil is packaged for storage and shipment. The cannabis infused oil is formed without any alcohol, does not have any decarboxylated cannabinoids and is non-psychoactive. In one example, the cannabis infused oil has between 100 milligrams and 2,000 milligrams of cannabinoids per fluid ounce of cannabis infused oil. In another example, before blending with oil, the cannabis material is combined with alcohol.
