Labour Ecient 5. Minimal factory shutdowns QUESTIONS Discuss why you think each of these 5 points are important in food processing.

ACTIVITY: Comparing traditional and commercial food processing methods We have learnt alot about food processing methods in our modern lives. However, the indigenous people of southern Africa have been preserving and processing food for many generations, and still use some of their traditional methods today. INSTRUCTIONS: 1. Read the following description of how beer is made in the Zulu culture. 2. Then answer the questions that follow. Zulu beer making Beer (utshwala) forms an integral part in the Zulu culture, especially at social gatherings and traditional ceremonies. Zulu beer is traditionally made by the women. To brew the beer, the women soak coarse sorghum and maize in water for one day, typically in a big drum-like imbiza pot. The following day, the broth is boiled over a fire and more dry sorghum is added to the mixture. After this, the mixture is mashed together and then allowed to cool for the rest of the day. The next day (day 3 of the brewing process), the mixture is filtered through a sieve to remove the big fibres. The sieve is made from palm fronds and the brew is poured from the big imbiza vessel into the serving vessel, iphangela, made from clay. The beer is now ready to be served. The iphangela is carried from brewery in the kraal (a semi-thatched hut which allows the smoke from the fire to escape and ensures a good supply of oxygen to ferment the mixture) to the drinking assembly. A woman scoops the beer into adrinking vessel, ukhamba (a small, round clay pot decorated with traditional patterns) using adried gourd and presents it on her knees to the men. She will first taste the beer to show the head of the household that she has brewed the beer properly, and then hand him the ukhamba, before passing it around to the rest. The beer contains 3% alcohol and it is nutritious as it is made from plant products without modern additives or colourants. Chapter 4. Food processing 69
