To sell juice wholesale, the juice must undergo a process that achieves a "5 log reduction in bacterial plate count." [ 11 ] The process must reduce the amount of microorganisms by 100,000 times. There are several processes available that can achieve a 5- log reduction , including heat pasteurization and ultraviolet light filtering, but the ...
Common methods for the preservation and processing of fruit juices include canning, pasteurization, concentrating, [17] freezing, evaporation, and spray drying. [citation needed] Although processing methods vary between juices, the general processing method of juices includes: [18] Washing and sorting food source; Juice extraction
There is a loss in non-extracted polyphenols, a class of phytonutrients, in fruit juice compared to whole plant foods. [7] Most polyphenols are bound to the plant fibers, and constitute the major portion of dietary polyphenols. [8] There is therefore a marked loss of phytonutrients in consuming fruits and vegetables through the juicing process ...
Juice extraction by milling is the process of squeezing the juice from the cane under a set of mills using high pressure between heavy iron rollers. Those mills can have from 3 up to 6 rolls; every set of mills is called a tandem mill or mill train. To improve the milling extraction efficiency, imbibition water is added at each mill.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.
Thick juice is mixed with low grade crystal sugar recycled from other parts of the process in a melter and filtered giving "standard liquor". The crystallization phase starts by feeding the standard liquor to the vacuum pans, typically at 76 Brix. [69] These pans are essentially single-effect evaporators, with their own vacuum source and condenser.
There are other process alternatives that can be applied to the processing grape juice, including cold-pressing the juice, and adding sulfur dioxide to the juice. [8] (p101-104) The juice can be further processed by removing water to produce a pure concentrate that can be used in a variety of juice products. [9]
