Abstract:
The present invention relates to a process for treating a lignocellulosic biomass pretreated beforehand (1), said process comprising the extraction of the free sugars from said pretreated biomass using an alcoholic or aqueous-alcoholic extraction solution (2), so as to obtain a liquid phase enriched in free sugars, called liquor (3), and a solid phase depleted in free sugars, called must (4).
Abstract:
Preferred embodiments of the present invention comprise the optional application of concentrations of an aqueous permanganate solution, such as an approximately 0.01% to approximately 50% liquid permanganate solution and preferably comprising approximately 20% sodium permanganate dosed at approximately 1 ppm to approximately 100 ppm to harvested sugar crops, such as sugarcane, sugar beets, and sweet sorghum, at one or more of the sugar processing steps for the crops. The steps where the liquid sodium permanganate may optionally be applied include at a sugar crop cutting step, a sugar crop conveying step, a sugar juice extraction step, a sugar juice clarifying step, and a clarifier muds filtration step. The application of liquid sodium permanganate in the processing of sugar from sugar crops results in reduced equipment fouling, reduced loss in juice purity, reduced scale formation, decreased turbidity in clarified juices, increased sugarcane processing rates, reduced sugar crop production costs, increased sugar product yield, and increased production capacity.

Abstract:
The present invention relates to a process for producing an extract derived from sugar cane, the process comprising: i) mixing a sugar cane derived product with ethanol to produce an extraction mixture comprising at least about 50% v/v ethanol; ii) allowing a precipitate to form in the extraction mixture; iii) removing the precipitate from the extraction mixture to obtain a super-natant; and iv) removing ethanol from the supernatant to produce the extract derived from sugar cane. The present invention further relates to extracts produced according to the process of the invention. The invention also relates to the use of such extracts in a method of lowering the available calorific value of a food or beverage, in treating or preventing disease, and as a nutritional supplement, dietary supplement, sports nutrition product, food coating or pharmaceutical product.
Abstract:
The invention provides processes for the extraction of sugar from sugar-bearing plant material such as sugar cane. Accordingly, in one aspect of the invention, a process for extracting sugar from sugar-bearing plant material comprises contacting the sugar-bearing plant material with an extractant solution comprising water and a surfactant; and separating the extractant solution from the sugar-bearing plant material. One example of a suitable surfactant is a poly(alkylene oxide) polymer such as a poly(propylene oxide) polymer, a poly(ethylene oxide) polymer, or a poly(propylene oxide)/(ethylene oxide) copolymer.
Abstract:
A composition and process for treating sugar solutions that includes one or more sources of ammonium that obtain a pH in water solution above pH 7.0, such as ammonium bicarbonate (NH4HCO3), ammonium phosphate dibasic (NH4)2HPO4, and ammonium sulfite (NH4)2SO3. The composition can also include a particulate sulfur reagent, an amorphous silica, a particulate aluminum reagent, a particulate phosphorous reagent, a particulate filter aid selected from diatomaceous earth and perlite, a particulate activated carbon, a particulate bleaching earth, a polymer decolorant, or combinations thereof. The individual materials can be pre-mixed before addition to the sugar solution, added individually to the sugar solution, or added as a combination of one or more singular ingredients and one or more pre-mixed ingredients. The invention can stabilize the pH of the sugar solution, reduce the calcium, magnesium or related ash constituents of the sugar solution, achieve color reduction of the sugar solution, or some combination of these effects.
