Band 9: Question: The diagram shows how yogurt is made at a factory. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The diagram illustrates the steps involved in the industrial production of yogurt, beginning with raw milk and ending with packaging.

Initially, raw milk is collected and analyzed for its solid, fat, and protein content using machines such as CEM SMART 6, ORACLE, and Sprint. Based on the analysis, the milk composition is adjusted and blended with other necessary ingredients. It is then pasteurized to eliminate harmful bacteria before undergoing homogenization, where the milk fat is evenly distributed.

Next, the homogenized milk is cooled and transferred to a tank where it is inoculated with starter cultures. Another round of analysis is conducted at this stage to monitor the consistency of its solid and fat content.

Following this, the mixture is held at a specific temperature and cooled again. At this point, flavors and fruit may be added to enhance taste. Finally, the finished yogurt is packaged and prepared for distribution to consumers.

Overall, the yogurt production process involves multiple steps of analysis, treatment, and conditioning to ensure quality and consistency.
