    Study Notes

    • Cream is a dairy product used for making butter and ghee.
    • Cream contains 20% or more fat and may contain certain salts in small quantities.
    • Cream can be distinguished by its fat percentage, such as table cream, light cream, and whipped cream.
    • Cream is rich in water, fat, protein, lactose, ash, and vitamins.
    • Cream is separated from milk by gravity or centrifugal force.
    • Whipped cream is created by knocking fat globules together until they coalesce around air pockets and fluid.
    • Plastic cream has a high fat content and remains an oil-in-water emulsion.
    • Cream for retail products is standardized to 35%, 18%, or 10% fat content.
    • Centrifugal separation is quicker and more efficient than gravity separation.
    • The efficiency of cream separation is influenced by factors such as bowl speed, residence time, density differential, and fat globule size.
    • Skimming efficiency is reduced if milk temperature falls below 22°C.
    • Heating milk to 50°C gives optimum skimming efficiency.
    • Cream screw regulates the ratio of skim milk to cream.
    • Cream containing less than 18% or more than 50% fat results in less efficient separation.
    • Poor quality milk or a separator in poor mechanical condition reduces skimming efficiency.
    • Centrifugal force throws milk to the outer wall of the bowl while cream is forced towards the center.
    • Separator bowl is assembled with gears and bearings to turn at high speed.
    • Separator bowl must be cleaned thoroughly to prevent microbial contamination and reduce corrosion.
    • Separator bowl should be flushed with warm skim milk and then clean water before dismantling and washing with hot water and detergent.
    • Separator bowl parts should be allowed to drain in a clean place after washing.
