The present invention relates to the provision of a method for producing a clear sugar beet pre-limitation juice and a coagulate removed from the pre-liming juice, and to a pre-liming juice and protein-containing fraction that are provided by means of said method. A decanter centrifuge having an angle between the longitudinal axis of the bowl and the generatrix of the conical portion of 6 to 10° is used.

A method for the qualitative distribution of sugar beet dry matter to products usable in food production, which includes the steps: (a) grinding of sugar beet material with a dry matter content of at least 85% by weight of grist, until at least 1% by weight of the grist attains a particle size of 1 μm to 1000 μm, (b) dividing the grist into fractions based on particle size and/or particle density, to create at least one fraction with a particle size below 500 μm and in the case of at least one fraction with a particle size above 500 μm, (c) or possibly subsequent subjection of the fraction with a particle size exceeding 500 μm to steps (a) and (b) until the desired quantity of the fraction with a particle size below 500 μm has been attained, preferably 1 to 20 times. The present teaching also relates to product produced in this way.

The present document describes a method for the detection of off-flavor maple syrup made from buddy maple sap or maple sap contaminated with buddy maple sap, or off-flavor maple sap comprising measuring a spectrophotometric property of a nanoparticle reactive with a buddy maple sample having a size of from about 1 nm to about 250 nm contacting a maple sample. A change in the spectrophotometric property is associated with an off-flavor maple syrup or maple sap sample, and no change in the spectrophotometric property is associated with a good flavor maple syrup or maple sap sample.

A method of processing raw sugar cane juice, comprising: reducing the pH of the sugar cane juice to a pH at which microbiological activity is substantially eliminated; separating chlorophyll from the sugar cane juice; separating particles having a diameter greater than 0.5 microns from the sugar cane juice; denaturing polyphenol oxidase (PPO) in the sugar cane juice by pasteurisation; separating the denatured polyphenol oxidase from the sugar cane juice.

The present invention relates to isolated polypeptides having dextranaseactivity, and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

The present invention relates to a process for purifying beet sugar juice and more particularly sugar juice obtained by pressing beets. It also relates to the purified juice and to the uses thereof, in particular as a fermentation substrate and for preparing granulated sugar. The purification process according to the invention comprises a step of passing the juice to be treated through a cellulose-fibre-based pre-layer. This process can be improved when the juice to be treated comprises between 0.1% and 4% of cellulose fibres.

An industrial process using kestose hydrolases to enable the use of sugar mixtures containing 1-kestose in the industrial production of sucrose (as crystallized sugar) by providing a method for the conversion of 1-kestose into sucrose and fructose in a sugar solution, containing kestose and more than 10 mM sucrose (3 g/L), and comprising the enzymatic hydrolysis (preferably using 1-FEH enzymes—EC 3.2.1.153) of 1-kestose. The process further provides a method of producing a polypeptide having 1-kestose hydrolase activity and a composition comprising the polypeptide.
