    摘要: Methods of producing a biodiesel derived from cocoa butter and in which the biodiesel possesses a cloud point as low as −61° F. generally include a two-step cold stabilization process in which at least two separate processes primarily aimed at reducing the cloud point of the resultant biodiesel are carried out. In some embodiments, one of the two cold stabilization steps involves desaturating the cocoa butter prior to transesterifying the cocoa butter for form biodiesel. Desaturating cocoa butter may include using a desaturase to convert saturated fatty acids present in the cocoa butter to unsaturated fatty acids. The second step of the two-step cold stabilization may employ urea clathration, which results in the formation of a lattice-like structure of urea having saturated fatty acid methyl esters trapped therein and which can easily be removed from the biodiesel. As a result of the two-step cold stabilization process, the amount of saturated and unsaturated fatty acids in the biodiesel is reduced and the cloud point of the biodiesel is correspondingly lowered.

    摘要: A process for producing a seed slurry (SSY) in a seed slurry apparatus (SSA) from solid seed particles (SSP) is disclosed, the seed slurry apparatus (SSA) comprising an input zone (IZ) and a heating zone (HZ), the input zone (IZ) feeding the heating zone (HZ) and the heating zone (HZ) comprising a heating arrangement (HA), said process comprising the steps of feeding the solid seed particles (SSP) from the input zone (IZ) into the heating zone (HZ), the solid seed particles having a seed composition, the seed composition comprising triglycerides, heating said seed composition in said heating zone (HZ) by means of said heating arrangement (HA) to obtain a seed slurry (SSY) at least partly on the basis of partly melted seed composition, wherein said heating involves measuring a seed slurry temperature representation of the seed slurry and said heating is at least partly controlled on the basis of the measured seed slurry temperature representation. Furthermore, a seed slurry apparatus (SSA) and use of a seed slurry (SSY) and a seed slurry apparatus (SSA) is disclosed.
