Solar pasteurization system is used to kill harmful bacteria present in the raw milk. It is carried out in dairy industries with the help of boiler and using wood or coal for heating of the milk. Due to the increment of global warming and its harmful effects, coal or wood should not be used for milk pasteurization system. Hence, researchers have started work on renewable energy source like solar energy for pasteurization system. Many scientists from all around the world have attempted to use solar energy for milk pasteurization system. The present review paper shows the research works carried out by researchers on milk pasteurization system. After several reviews, it has been found that solar energy is the best solution for milk pasteurization system.
