Method for extraction of sugar

Patent Number: 8440022
Publication Date: 2013-05-14
Inventor:

A method for extraction of sugar from a sugar containing biomass is disclosed, wherein the sugar containing biomass a) is introduced in an extraction device (1), b) is treated with steam having a temperature of between 103 and 124° C., c) is treated in one or more steps with hot water having a temperature of 65-85° C., and d) is subjected to one or more compression steps, wherein a sugar containing solution is extracted from the sugar containing biomass in each of the steps c) and ...

Fractionation of lignocellulosic material using ionic liquids

Patent Number: 8435355
Publication Date: 2013-05-07
Inventors: ;

Lignocellulosic biomass materials are fractionated by dissolving at least a portion of the lignocellulosic material in an ionic liquid and separating the resulting mixture into a cellulose-enriched fraction and/or a lignin-enriched fraction. The cellulose-enriched fraction contains about 10 percentage points more glucose than the weight percent glucose contained in the original lignocellulosic biomass material. In certain embodiments, the lignin-enriched fraction includes a lignin content ...

Water stable compositions and articles comprising starch and methods of making the same

Patent Number: 8435354
Publication Date: 2013-05-07
Inventors: ; ; ;

Thermoplastic polymer compositions comprising starch and articles made therefrom are water stable or may be rendered so. One method of making water stable thermoplastic compositions comprises the steps of mixing destructured starch with polyhydric alcohol and triglyceride, and forming a transesterification reaction product from at least a portion of the polyhydric alcohol and ...

Method of extracting starches and sugar from biological material using controlled cavitation

Patent Number: 8430968
Publication Date: 2013-04-30
Inventors: ;

A method of extracting sugar, starch, and/or carbohydrates from feed material such as corn or corn stover is disclosed. The feed material is mixed with liquid and perhaps accelerants to form a mixture. The mixture is pumped through a controlled cavitation reactor, where it is exposed to shockwaves from cavitation events. The shockwaves open pores in the feed material and force liquid in and out of the pores to liberate trapped sugars and starches, which are dissolved in the liquid for ...
