The present document describes a system and a process for the extraction of several products from apple peel. There are several unit operations involved including an ultrafiltration unit, concentration unit, and a three stage counter current separator centrifuge wherein water is used as the solvent. The final products that are extracted from apple peel include pectin, syrup, fibers, as well as soluble and dried retenate fractions.

A batch centrifuge having a filter screen that can be expeditiously removed and replaced and that is more rigid and more durable than filter screens that are typically employed in current practice. The batch centrifuge may include a centrifuge basket and a cylindrical filter screen disposed within the centrifuge basket, wherein the filter screen is formed of a plurality of curved panels that fit together at adjoining edges. In some embodiments, each of the curved panels may be small enough to fit through an opening in the top of the centrifuge basket without being bent or otherwise deformed.

The present invention relates to a process for the selective isolation of highly purified, crystalline D-mannose from complex sugar mixtures, in particular from mixed wood sugars, more particularly from spent sulfite liquor (SSL). The process of the present invention is based on converting mannose into essentially pure mannose bisulfite adducts. Subsequent oxidative recovery of mannose from the mannose bisulfite adducts renders crystalline mannose in improved yields and purities.

Disclosed is a method of inhibiting isomerization of a reducing saccharide in an aqueous solution containing said reducing saccharide upon thermal treatment of said aqueous saccharide solution by acidifying the aqueous saccharide solution prior to its thermal treatment, and the use of the thermally treated aqueous solution containing said reducing saccharide for producing a biological product.

A method of liquefying biomass. The method includes the steps of contacting biomass with a solution comprising an acyl halide and an acid; and then contacting the biomass with a reductant.

The present invention relates to systems, methods, and processes for the production of conversion products such as furanic products from biomass such as lignocellulosic materials.

An industrialization method for comprehensive utilization of Stevia rebaudiana. The major improvement is in that the Stevia rebaudiana is extracted by using a high-concentration alcohol solution, then the extracted solution is purified by using an organic solvent, and the pH of the extracted solution is adjusted to be alkaline according to the acidic characteristic of chlorogenic acid to enable the chlorogenic acid to be formed into a salt and have an increased polarity so as to achieve effective separation of the chlorogenic acid and a glucoside component in an adsorption process. The method allows the high-quality stevioside and chlorogenic acid to be obtained, significantly improves the comprehensive utilization rate of Stevia rebaudiana, reduces the waste of natural Stevia rebaudiana resources, reduces the resource consumption in a production process, reduces waste discharge, and is a high-benefit green production process.
