Inhibition of the growth and activity of Ciostr;d;um by lacto~a~ji~us r~amnosus and its application in the food industry are described. Proposed uses include the prevention of butyric acid fermentation and use in cheesemaking.

equipment

Kravets, B.K. (Anton Weizddrfer Pr Co. CmbH, 85435 Erding, Germany) German Federal Republic Patent Application DE 44 33 744 Al [in German!

A process and the equipment for the preparation of a wide range of food emulsions and suspensions, including beverages, soups, sauces and dairy products. The process involves the application of a cavitation field to a combination of ingredients.

Sterilization

A probiotic composition that can be included in foods to increase their nutritional value. The composition comprises one or more probiotic microorganism (e.g. Biiidobacterium) and a carrier to transport microorganisms to the large bowel or other regions of the gastrointestinal tract once ingested. The carrier is a resistant starch (e.g. high-amylose starch), which acts as a growth or maintenance medium for microorganisms following digestion.

process

Stauder, A. (Stauder, 74354 Besigheim, Germany) German Federal Republic Patent Application DE 44 32 228 Al [in German]

A process for the preservation of foods, in which the food is placed in a chamber and exposed to an electrical discharge in the gas in the chamber, induced by two or more electrodes attached to a highfrequency pulsed potential difference with a small pulse width and large amplitude.

Fruit, vegetables & nuts

that are treated, usually thermally, to increase shelf life before packaging. It is essential to know that following treatment and subsequent packaging the product is free from microorganisms. A method and device for testing a liquid or semi-liquid substance (particularly foods) for microbiological spoilage are described. In the method, spaced first and second electrodes are contacted with the substance in undiluted form, an electrical current is supplied between the electrodes, the voltage or current between the electrodes is monitored, and a signal is produced when the voltage exceeds, or the current fails below, a predetermined value indicative of contamination. A test device for carrying out this method comprises an insulating substrate, and first and second carbon electrodes formed on the substrate by screen process printing using a carbon ink. At least the end portions of the electrodes at one end of the test device should be accessible electrically for connection
