Publication number: 20090017503Abstract: A method for separating saccharide components and lignin fractions from a concentrated acid treated lignocellulosic biomass is disclosed. The method involves precipitating the saccharide components by adding an organic solvent to the biomass slurry. The acid may then be recovered, for example, by filtration or by countercurrent washing and the organic solvent may be flashed and recycled. During acid recovery and organic recovery steps, two main lignocellulose components (hemicellulose and lignin) as well as minor components such as acetic acid are separated as well. The method decreases the amount of cellulase required for hydrolysis, increases hydrolysis rates, reduces formation of inhibitor molecules, increase sugar yields, produces high value by-products such as high quality lignin and hemicellulose, and decreases energy and equipment costs.Type: ApplicationFiled: August 7, 2006Publication date: January 15, 2009Applicant: THE TRUSTEES OF DARTMOUTH COLLEGEInventors: Yi-Heng Percival Zhang, Lee R.

Publication number: 20080300402Abstract: A process for recovering Rebaudioside A from Stevia rebaudiana Bertoni plants is provided and includes the steps of sequentially extracting plant material with a first solvent to obtain a first extract, filtering the first extract and passing the first extract through a polar resin to obtain a filtrate, and purifying the filtrate to obtain a crystalline-containing material. With further purification, a product containing over 99% Rebaudioside A is obtained. The present invention is also directed toward a method of purifying stevia glycosides to obtain purified Rebaudioside A. In one embodiment, the method includes silica gel column chromatography using an solvent comprising ethyl acetate and ethanol.Type: ApplicationFiled: December 17, 2007Publication date: December 4, 2008Inventors: Mingfu Yang, Jun Hua, Ling Qin

Publication number: 20080293114Abstract: A continuous process for treating a lignocellulosic feedstock is provided. This method comprises pretreating the lignocellulosic feedstock under pressure in a pretreatment reactor at a pH between about 0.4 and about 2.0. One or more than one soluble base is added to this pressurized, pretreated feedstock after it exits the pretreatment reactor to adjust the pretreated lignocellulosic feedstock to an intermediate pH of between about pH 2.5 to about pH 3.5. This pressurized, partially-neutralized feedstock is then further processed at the intermediate pH. This may include flashing one or more than one time at the intermediate pH. The pH of the pressurized, partially-neutralized feedstock may then be adjusted with one or more than one base to produce a neutralized feedstock having a pH between about 4 and about 6. Prior to adjusting the pH to between about 2.5 and about 3.5, the pressurized, pretreated feedstock may be partially depressurized.Type: ApplicationFiled: June 2, 2006Publication date: November 27, 2008Applicant: IOGEN ENERGY CORPORATIONInventors: Brian Foody, Jeffrey S.

Publication number: 20080261291Abstract: Procedure for the obtaining of genin and sapogenins extracts by enzymatic hydrolysis of kernels derived of the family Sapotaceae, genus Calocarpum, Chrysophyllum and Lucuma. The enzymes that catalyzes the hydrolysis are exogenous ?-glucosidases, of vegetable or microbial origin. The process uses mainly diverse kernel (seeds removed of the endocarp) derived but can also use the cyanogenic glycoside, lucumin and the related similar glycosides directly. It is also object of protection the process for the obtaining of these glycosides, starting of those kernels derived and the usage of these in the obtaining of genin and sapogenins and its uses in cosmetic and dermatologic compositions. The genin and sapogenins extracts are the main products used with these basic similar aims. The obtained genin extract are used in topical compositions to promote the opening of the pore facilitating the epithelial penetration or it can be used as flavouring or scent agent in foods or in alternating similar uses like in perfumery.Type: ApplicationFiled: July 21, 2004Publication date: October 23, 2008Inventor: Luis De La Llata Romero
