Patent Type: United States Patent  5 928 691  En:en  Filing date: 1.5.97 (saan: 504153)

Abstract: Dairy beveragescan be fortified with calcium salts, but these have a tendency to react with the proteins,causing them to precipitate, which makes the product unattractive. This can be overcome byusing gums, etc., but these increase the viscosity of the beverage, which may not beacceptable. This patent describes a method of fortifying dairy products that overcomesthese problems. A soluble calcium salt, which is preferably calcium lactate, is formedinto a complex with an alkali metal citrate, which is preferably potassium citrate. It canbe used in confectionery, milk beverages, ice cream and juice products.

Abstract: Beer that hasbeen filtered through freshly cleaned membrane filters containing polyamide tends toproduce excessive foam (gushing), which is thought to be caused by the action of thecalcium ions absorbed by the polyamide from the rinsing water and released into the beer. A method for producing cold-filtered beer using the usual polyamide membrane filtersis disclosed, which reduces the gushing problem.  After filtration, the membranefilter is washed and rinsed using an acidic aqueous substance with a pH less than 5.0, orthe rinsing water may be treated to reduce the quantity of calcium ions contained.

Patent Type: United States Patent 5 928 698  En:en  Filing date: 31.3.98 (saan: 504155)

Abstract: Carambola, whichis known as star fruit, has a pleasant taste. However, it has a thick rind that has anunpleasant taste and texture and that is difficult to remove because of the star-likeshape of the fruit. This patent describes a beverage that is made from Averrhoa carambolaand the method for producing it. The whole fruit is macerated to form a slurry and theliquid is then separated and processed. The rind is said to enhance the flavour andpossibly the nutritional value of the extract.

Patent Type: British Patent Application  2 333 586  En:en  Priority data: (UK) (24.1.98)   Filing date: 20.1.99   Seepublished patent document for Designated Contracting States. (saan: 502469)

Abstract: The inventionrelates to self-cooling beverage containers such as cans.  The cooling means may beprovided as a self-contained cartridge inside the container, but the actuation means maybe outside, with cooling being initiated, for example, when the container is opened. The cooling means comprises a phase-change medium such as water, which is adapted tochange phase in use and extract heat from the beverage. Means such as activated carbon,ammonium nitrate and a polymer may be provided to adsorb or absorb the medium.  Themedium may be arranged to vaporize into a vaporization chamber at sub-atmosphericpressure. The cooling means may be combined with a widget to avoid separate mounting of acooling device.  The invention can also be applied to kegs and to containers offoodstuffs such as ice cream and yoghurt.  It can also be used as a heating system.
