The diagram depicts the production of ketchup. Looking from an overall perspective, it is readily apparent that this man-made process comprises various stages, beginning with tomatoes being picked from tomato trees, followed by a variety of physical and chemical steps, and ending with finished products being served with a number of different types of fast food.
At the first stage of the process, tomatoes are collected and put in baskets by farmers, after which freshly-picked tomatoes are sorted into good-quality and rotten ones by using several kinds of techniques. Next, tomatoes are dispatched to ketchup factories by using trucks, where they are carefully peeled and processed to eliminate the stalk and seeds. In the subsequent step, peeled tomatoes are put in a container with a particular volume, in which they are intensely crushed to become a more liquid form. After that, sugar and vinegar are added to the liquid product along with an appropriate amount of salt.
The process continues with the mixture being boiled to a specific temperature to become ketchup, with the container being kept close with a lid. Once the ketchup has been cooled down for two hours, it is poured into bottles made of various materials. Following this, ketchup bottles are labelled and go through a test of quality control made by food supervisors. Subsequently, bottles of ketchup are packed into boxes which are then distributed to supermarkets. Finally, after being bought, ketchup is used as a condiment when eating fast food such as hamburgers, fries, etc.
