Abstract: The invention relates to a process for deacidifying a coffee extract without the introduction of foreign products by selective absorption with a natural material, chitosan. In this process, the extract is contacted with chitosan in divided form and the deacidified extract is collected after separation from the chitosan. Preferably the coffee extract is contacted with chitosan for 5 to 30 minutes at a temperature from 10.degree. to 80.degree. C. and in ratios (extract/chitosan) of from 15 to 400 ml per gram. The chitosan may either be suspended in the coffee extract, or the coffee extract may be percolated through a column filled with chitosan.

Abstract: Cheese is produced by a process wherein milk is subjected to partial ultrafiltration, heat denatured serum proteins are added to the milk before or after ultrafiltration, the milk is coagulated to form a curd wherein 1/4 to 1/2 of the total serum proteins contained in the curd are the added heat denatured proteins, and the curd is drained to produce curd containing a total amount of serum proteins substantially equal to the total serum protein content of the starting milk. The addition of heat denatured serum proteins overcomes a problem of alternation in the normal ripening cycle of cheeses produced from ultrafiltered milk containing an increased quantity of soluble serum proteins.

Abstract: The invention relates to a mould of the type shown in FIG. 3. The mould for packaging desserts, particularly ice-cream cake with coating syrup, is in the form of a cup comprising an opening through which the dessert is introduced into and removed from the mould. The mould comprises a first compartment near the opening which defines a first space and which is intended to receive a product solid at the storage temperature and a second compartment which defines a second space below the first space and which is intended to receive a syrup liquid at the storage temperature. The second compartment comprises several cells distributed in the base of the cup, each of the cells communicating through an opening with the first compartment and being separated from the other cells by walls simultaneously acting as stiffeners for the mould.

Abstract: The present invention relates to a process for recovering proteins from lactoserum. This process comprises subjecting a lactoserum to a heat treatment to denature the proteins present in it and then separating the denatured proteins from the other non-fat constituents of the lactoserum by ultrafiltration. Alternatively, the ultrafiltered lactoserum, i.e. the retentate, is subjected to a complementary heat treatment for denaturing the proteins.The proteins thus recovered may be used in dietetic or infant nutrition and in cheese making.

Abstract: On a conveyor belt, an ejection mechanism ejects objects travelling thereon which do not fulfill predetermined requirements as detected by a detecting device. To speed up the return of the ejection mechanism to its home position, the ejection cycle is divided into several movements. First a striking element is propelled against the object to be ejected, then the striking mechanism pivots on a fixed point to bring the striking element out of the path of the objects. Next the striking element is retracted and the ejection mechanism pivots back to its original position. A locking device may be used to retain the ejection mechanism in the deflected position to ensure that the striking element is completely retracted before the ejection mechanism pivots back to the home position.
