Abstract: In a process for preparing a tobacco blend, at least two different types of tobacco are thermally treated and blended so as to form the tobacco blend. Thermal treatment as well as blending of the different types of tobacco is performed by introducing the different types of tobacco into a combined thermal treating and blending unit, where thermally treating as well as blending of the at least two different types of tobacco is performed.

Abstract: A system for producing expanded tobacco, comprises a tobacco expansion apparatus, in which the tobacco is expanded, at least a first tobacco supply unit for providing tobacco containing at least one suitable chemical solvent other than water to prepare the tobacco for expansion, at least a second tobacco supply unit for providing tobacco containing only water as a solvent to prepare the tobacco for expansion and at least a first feed unit for introducing tobacco from the at least first tobacco supply unit and the at least second tobacco supply unit into the tobacco expansion apparatus.

Abstract: A structured protein product is prepared from a protein material having a three-dimensional organization solely by applying osmotic force. The process comprises exchanging the water in said protein material with an osmotic agent by compacting the protein material in an envelope of semi-permeable material which is closed and then immersed in a solution of osmotic agent.The product obtained may be used in the production of deep-frozen, preserved or dehydrated food products.

Abstract: The present invention provides a process for preparing high nutritive fibres from fish proteins which comprises grinding whole fish or fish pieces in the presence of water and then adding alkali to the ground fish. The alkali/fish mixture is then heated and cooled and the cooled mixture is then passed through a colloid mill thereby eliminating solid particles to obtain a protein solution. The solution is then injected through a spinneret into an aqueous acid medium causing the coagulation of the proteins into fibres. The fibres are then washed, set by heating and then neutralized. The fibres obtained by this process are also described.
