My essay:

Tomato ketchup is a thick, rich sauce made of tomatoes, with seasonings, and commonly used on hamburgers and fries. The flow chart illustrates the process of making this for sale.

Overall, there are three major stages in the process: harvesting ripened tomatoes on the vine, cooking the fruits in a factory, packaging and shipping the ketchup to the consumers. The first stage is a simple, but labour intensive process, whereas the second is an elaborate one consisting of six steps. The farming of the tomatoes is not shown.

In detail, the process begins with two manual processes, one for farmers picking tomatoes into a basket, and the other for them inspecting the tomatoes. The bad one is discarded and the others are loaded in a truck and taken to a manufacturing facility. In the next stage, the skin, seed and stalk are removed from the tomatoes. The pulp is put in a container, where it is crushed by a metal press into a sauce. The sauce is seasoned with sugar, vinegar and salt, and then boiled. After being cooked, it is left to cool for two hours. The third stage involves bottling the ketchup and labeling the container. It goes through a quality control process, in which training personnel tests the output product to ensure its quality. It is then packaged in boxes and delivered to supermarkets, where consumers buy them.
