The diagram illustrate the process of making yogurt in seven steps. Firstly, pouring milk into the pot for heating process. Milk is heated to 90 degrees celcius for 30 minutes. If the milk is heated longer, this helps to makes the yougurt thicker. Secondly, the milk is cooled down to 44 degrees celcius and added live bacteria as yougurt starter for fermentation step. Next, the milk that has been added with bacteria is left at 37 degrees celcius for 4 hours to allow bacteria to work.
Then, keep the yougurt in a refrigerator for a while. For a sweet taste, add some sugar to the yougurt. Final steps, the yougurt is packaged in a safe packaging and ready for delivery.
Overall, thats all the process of making yougurt involves heating, cooling, fermenting by live bacteria, sweetened to produce good quality yougurt, and the last is preparing to shipment.
