Abstract: The invention relates to a device for treating a fluid product (4) such as a dairy product, with heat (6), the product (8) being transported with steam through a product conduit for treating the product with heat coming from the steam, the product treated with heat being subsequently supplied to an expansion tank (10) for cooling the product.

Abstract: Arrangement for measuring physico-chemical properties of liquid, such as solutions, dispersions and emulsions. The arrangement comprises a light source for producing and emitting light in the liquid, a detector for detecting said light after being scattered by said liquid, processing means arranged for receiving an output signal from said detector. The processing means is further arranged to calculate a maximum value of the mean square displacement <&Dgr;rm2> from the autocorrelation function g(2) as a function of time and the value of the property from said calculated maximum value of the mean square displacement <&Dgr;rm2>.

Abstract: The invention relates primarily to a number of lantibiotics similar to nisin A, which differ from nisin A by substitution, deletion or insertion of one or more amino acids, such as, in particular, the naturally occurring analogue of nisin A, termed nisin Z, which has the structure given above. Lantibiotics of this type are particularly suitable for preserving foodstuffs for humans and animals. This preservation takes place by the use of these lantibiotics themselves or of microorganisms producing these lantibiotics, in particular lactic acid bacteria, in the preparation or storage of foodstuffs.

Abstract: Continuous method for dissolving milk proteins containing water insoluble casein by passing said milk proteins together with one or more solubilizers and with water in a continuous stream through a closed reaction chamber by means of a positive displacement pump and converting the mixture within said reaction chamber under the influence of shearing forces into a solution having a dry solids content within the range of from 20 to 70% by weight. The solution can be removed from the reaction chamber as liquid jets which are dried while forming endless threads or films which can be cut or milled. Water soluble milk protein product having a particle density amounting to at least 90% of the specific density. Apparatus for performing said method containing a positive displacement pump and a closed reaction chamber connected to said pump by way of the discharge conduit of said pump, in which reaction chamber preferably a rotary means, such as a colloid mill or a serrated impeller, is provided.
