The present invention is on the field of antimicrobial active substances. In addition to novel uses of distinct antimicrobial mixtures according to the invention, the present invention also relates to preparations containing such mixtures, particularly preparations serving for nutrition or pleasure or pharmaceutical preparations, as well as methods for preparing such preparations and methods for antimicrobial treatment of preparations serving for nutrition or pleasure or pharmaceutical preparations.

A concentrated fruit juice powder obtained by a convection current vacuum freeze drying process that includes: selecting and preparing fruits by predetermined quality guideline; extracting fruit juice by inserting the fruits into a screw press juicing apparatus having a precutter and a screw press whose body surface varies non-linearly, which is configured to achieve a maximum extraction efficiency; adding probiotics into the extracted fruit juice; freezing the fruit juice mixed with the probiotics in molds using an individual quick freezer (IQF) to obtain frozen fruit juice blocks; and vacuum freezing the frozen fruit juice blocks using a convection current vacuum freeze drying apparatus.

Systems and methods for packing solutions for oxygen-sensitive articles such as food, beverages, and pharmaceuticals, as well as biological samples and/or cultures are disclosed. In preferred systems and methods, oxygen is removed using a bi-enzymatic reaction sequence that recycles and depletes oxygen to extinction, preferably using an oxidase and a catalase as catalysts and a carbohydrate as co-substrate while at least one the enzymes is in a hydrogel or other polymeric formulation.

In a method for the inactivation of microorganisms in liquid foods, a liquid food is mixed with a pressurized, liquefied gas at a pressure which is sufficient to maintain the liquefied gas in the liquid state. The mixture of food and gas is then depressurized to a pressure at which the liquefied gas is vaporized. According to the invention, before or during the depressurization to the second pressure, the mixture is guided through a pipeline and brought up to a flow speed in the pipeline which is sufficient to form cavitations in the liquid food.

Plug for high-pressure processing machines with a bag, comprising a duct for the passage of a pressure-transmitting fluid to the bag, another duct for filling and emptying of a product to be pressurized and a valve. The plug is further provided with a rod for opening and closing the valve. Said rod is located in the duct for the product and has its own inner duct joined to a cleaning agent chamber for the passage of the cleaning agent through the product duct. The invention also relates to a machine incorporating said plug and a method for the processing of pumpable substances. Hygienic design and very high pressure sealing requirements are met by the invention.
