The invention provides a method for treating rootor tuber juice, comprising a) a pretreatment of the rootor tuber juice to remove rootor tuber lipids to a level below 28 g/kg dry weight; b) cooling the rootor tuber juice to a temperature of ?0.3? C. to ?16? C. to form ice crystals; and c) separating the ice crystals from the rootor tuber juice to obtain, as a first rootor tuber juice product, a concentrated rootor tuber juice. In addition, the invention provides methods to obtain protein depleted rootor tuber juice products, as well as products comprising rootor tuber free amino acids, and uses thereof.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

The present invention concerns a potato protein composition comprising: patatin; and optionally insoluble fibers from potato and/or other potato proteins,
wherein the protein, preferably the potato protein, has an aqueous solubility at pH=7.0 and 20? C. of at least 60%, and
wherein the composition has an acetylcholinesterase (ACE) activity of less than 30 U/g, based on the dry weight of the protein, preferably the potato protein.

The present invention further concerns a composition comprising fat or oil comprising at least one fatty acid group having 14 carbon atoms or less, and the said potato protein composition.

The invention is directed to a method of forming a gel, to a gel obtainable by said method, to a heat treated native potato protease inhibitor, to the use of said protease inhibitor, and to a foodstuff comprising said gel or said protease inhibitor. The method includes: providing a solution of native potato protease inhibitor isolate having an isoelectric point of more than 6.0 and a molecular weight of less than 35 kDa; subjecting the native potato protease inhibitor solution to a heat treatment to a temperature of 65-121 C. for at least 10 minutes, or an UHT treatment at temperatures above 121 C., at an ionic strength of less than 60 mM and a pH of less than 4.5 yielding a heat treated native potato protease inhibitor solution; and setting the ionic strength of the native potato protease inhibitor solution to more than 60 mM.
