Disclosed is a method of separating carbohydrate, including: mixing formic acid with heteropoly acid, chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof to form a mixing liquid. The method also includes dissolving a cellulose biomass by the mixing liquid to form a solution, mixing water and the solution to hydrolyze the cellulose biomass for forming a carbohydrate solution, and mixing an extractant and the carbohydrate solution to extract the formic acid out of the carbohydrate solution. The heteropoly acid, the chloride or bromide of lithium, magnesium, calcium, zinc, or iron, or combinations thereof in the carbohydrate solution is separated out of the carbohydrate solution by ion exclusion chromatography separation to obtain a carbohydrate.

A Stevia extract made from leaves of the Stevia rebaudiana plant is described. The extract has desired levels of steviol glycosides and is useful in food, beverage, and other consumable products.

The method for purifying oses from hemicellulose originating from lignocellulosic biomass includes eliminating the cellulose matrix and the solid residues and/or the suspended materials from the acid hydrolysate containing oses in order to obtain a clarified hydrolysate, and subjecting the clarified hydrolysate, without adding any basic chemical reagent to increase the pH to at least one step of ultrafiltration and/or to at least one step of nanofiltration, so as to obtain a filtrate containing the majority of the pentoses and a retentate containing the species likely to precipitate under the effect of an increase in the pH. The filtrate is treated by at least one step of electrodialysis so as to recover the acid catalyst from an acid-supplemented solution, and obtain a deacidified filtrate.

A screen for an extractor system can have a top surface that a solid material contacts during operation of the extractor, a bottom surface opposite the top surface, and a plurality of apertures extending from the top surface through the bottom surface. In one example, the bottom surface of the screen is coated with a non-stick coating while the top surface of the screen is devoid of the non-stick coating.

The present invention relates to methods and systems for optimization of dilution of a viscous starting material to isolate and/or concentrate the product of interest from the starting source material such that the process minimizes the volume of diluent and the total volume of the waste stream generated during the process as well as maximizing the yield of desired product. The system employs cross-flow filtration modules with sub-channels that are equidistant to the inlet and outlet of said modules and such modules are characterized by optimal channel height, optimal transmembrane pressure, etc., which are selected in order to achieve the best combination of product quality and production yield.
