  • Patent number: 5925398
    Abstract: A method of making processed mozzarella cheese that does not require any aging or refrigeration during storage is disclosed herein. This is accomplished by dicing cheese curd, adding emulsifier, and thermomechanically treating in an extruder to stretch and cook the curd. Fresh processed mozzarella cheese having functionality similar to the aged mozzarella cheese is achieved by addition of emulsifier to soften casein and inputting sufficient mechanical energy to establish the appropriate fibrous structure. Longer shelf-life and storage without refrigeration is achieved by application of suitable time-temperature combination to inactivate proteolytic enzymes and microorganisms.

  • Patent number: 5722317
    Abstract: An aseptic food processing system including a non invasive temperature measurement apparatus capable of processing low acid particulate foods. A magnetic particle is inserted into a food particle in the aseptic system and undergoes heating corresponding to a cold zone in the food product being processed. After heating, the particle is passed by one or more magnetic sensors disposed about the food stream path. The magnetic particle magnetizes in proportion to its magnetic susceptibility as it passes magnets included in the sensors. The particle is chosen to be paramagnetic at processing temperature ranges, and produces a magnetization in a sensor coil in the sensor which is proportional to the magnetic susceptibility. Because the susceptibility varies with temperature, actual temperature measurements of cold zone heating within the food particles may be obtained.

  • Patent number: 5260079
    Abstract: A method of and equipment for controlling the content of fat in milk. Whole milk is separated into skim milk. Some of the cream is returned to the skim milk to create a standardized milk. The standardized milk is employed to derive a parameter that dictates how much cream is to be added. The fat contents detected in the standardized milk are exploited to vary the amount of added cream. The density of the skim milk is measured at intervals and the results are stored. The density of the standardized milk is measured and more or less cream is added until a prescribed difference between the skim milk and the standardized milk, corresponding to the desired fat content in the standardized milk, is obtained. The density of the skim milk and that of the standardized milk are measured in the same sensor. The result of each measurement of the density of the skim milk is compared with the stored result.
