Definitions

  • the present invention relates to a cleaning agent for an electric motor-operated kitchen appliance, in particular with a cooking function, and to a method for cleaning a kitchen appliance with the cleaning agent portion according to the invention. Furthermore, the subject of the present invention is a use of the cleaning agent according to the invention for cleaning an electric motor-operated food processor.
  • Electromotive food processors are very popular. In addition to the actual function of the food processor, current devices have a cooking function, so that food can be prepared in the food processor.
  • starchy dishes such as risotto or pudding
  • dirt can also appear in the mixing bowl and sometimes on the mixing tool both after cleaning in the dishwasher and after cleaning by hand to be available.
  • the mixing bowls are made of stainless steel.
  • Starch stains such as those that occur when cooking potatoes, pasta, rice and especially risotto, are often difficult to remove from stainless steel.
  • starch stains can often be seen even after cleaning in the dishwasher or by hand.
  • Such starch stains can be removed with vinegar, for example, after the actual cleaning. A further cleaning step is therefore required.
  • the mixing bowl must then be rinsed again to prevent dishes being prepared in the mixing bowl from taking on the taste of vinegar.
  • the present invention therefore relates to a cleaning agent for cleaning an electric motor-operated kitchen appliance, in particular a kitchen appliance with a heating function, characterized in that it has at least one amylase and at least one protease, the weight ratio of amylase to protease being 1:10 to 5 :1.
  • the present invention therefore relates to a cleaning agent for cleaning an electric motor-operated kitchen appliance, in particular a kitchen appliance with a heating function, characterized in that it has at least one amylase and at least one protease, with 0.05 to 1.0% by weight , preferably 0.1 to 0.6 wt .-%, in particular 0.12 to 0.4 wt .-% active enzyme protein of amylase (based on the amount of the total composition) are used.
  • the cleaning agent according to the invention can be introduced directly into the mixing bowl of a food processor.
  • the addition of water creates a cleaning liquid inside the bowl, which cleans the inside of the bowl on the walls and in the area of the floor, i.e. cleans the surfaces that come into contact with the cleaning liquid and thus with the cleaning agent according to the invention. If an agitator is switched on, the cleaning can be particularly effective, since the liquid then comes into contact with other areas of the mixing bowl, as the liquid rises up the edge of the mixing bowl.
  • the cleaning agent according to the invention has better cleaning performance, in particular when removing starch stains from stainless steel.
  • Cleaning agents for dishwashers could also be used to clean mixing bowls, in particular kitchen machines operated by electric motors.
  • these are also not effective in removing starch stains from stainless steel.
  • these are often in the form of tabs. If you now turn on a food processor with an agitator to improve the cleaning performance, the agitator can be damaged by contact with the tab, especially if the agitator is designed in the manner of knives.
  • the cleaning agent can preferably be present in portions.
  • Appropriate portions of detergent are matched to the volume of standard mixing bowls in food processors. This makes handling easy and safe for the consumer.
  • concentration of enzymes and other active substances that may be present in the cleaning liquid can be ensured.
  • the cleaning agent according to the invention is particularly readily soluble in water, so that the mixing bowl can be cleaned in a short time of preferably 10 minutes or less, in particular 7 minutes or less.
  • the cleaning agent is present as a cleaning agent portion.
  • the detergent is in a water-soluble or water-dispersible container (pouch) before.
  • water-soluble or water-dispersible means that the container dissolves or disperses in cold water (water temperature: 20 °C) with stirring within 30 s or less, so that the cleaning agent is completely available.
  • Corresponding pouches are usually made of PVA and are known to the person skilled in the art.
  • At least one includes, but is not limited to, 1, 2, 3, 4, 5, 6 and more.
  • the information refers to the type of ingredient and not to the absolute number of molecules.
  • At least one surfactant thus means, for example, at least one type of surfactant, i.e. one type of surfactant or a mixture of several different surfactants can be meant.
  • the information refers to all compounds of the type specified that are contained in the composition/mixture, i.e. the composition does not contain any other compounds of this type beyond the specified amount of the corresponding compounds.
  • the percentages by weight given in this application relate to the active substance content in g, based on the weight of the entire composition in g.
  • the specified pH value in various embodiments relates to a 10% solution of the respective composition in distilled water at 25°C.
