Processing: food technology

Module 19

What is food technology?

  1. What is food technology?

Food technology incorporates a broad field of study, but definitely deals with altering raw materials to food products. Raw materials include items such as bananas, fish, grains of wheat and potatoes. Some of these raw materials can be eaten as they are; bananas, for example. Other raw materials need to be processed before they can be presented as tasty. We need to distinguish between two core ideas: primary processing and secondary processing . Primary processing involves a process in which a raw material is made into a usable product (grains of wheat, for instance, are made into flour). When the flour is used to bake bread, we have to do with secondary processing.

Assignment 1:

[lo 2.2]

Illustrate examples of your own of primary and secondary processing

When we apply the process of food technology, it is necessary to have acquired particular knowledge and skills. We shall learn about different ingredients and their nutritive values. We shall have to be able to use particular tools and equipment effectively to be able to produce food products and we also have to understand why it is important to know about safety precautions and hygiene. To produce a product that will be popular, we shall have to do the necessary research, which will require knowledge related to the utilisation of computers and appropriate software. Sometimes the food technology process involves developing particular recipes and it might often be necessary to follow instructions precisely. Every successful enterprise, including food technology, also requires quality control. Are the ingredients that I use in my product safe in all instances ? is only one of the questions that a food technologist has to ask.

Assignment 2:

[lo 2.2]

Answer the following questions:

  1. Make a list of a number of foods that can be eaten raw, without any processing. Explain how two foods can be processed to become other products, for example: Meat (raw material) is dried to provide biltong (processed material).
  1. Design a memory chart to provide a clear illustration of the knowledge and skills that are required in the world of food technology.
  2. HYGIENE AND SAFETY
  1. Food hygiene and personal hygiene

Before designing a food product, you need to increase your knowledge of food hygiene, or you might design a food product that is unsafe for consumption by people!

Food hygiene consists of a set of rules that are directed towards keeping food clean. The main methods for keeping food clean are:

  • protecting food against bacteria;
  • preventing bacteria from multiplying in food, and
  • destroying bacteria by means of cooking.

Poor food hygiene in the food industry often leads to food poisoning. This can lead to legal steps being taken by clients against an enterprise, which may result in heavy fines. To sell food that is unsafe to eat is a contravention of the Food Safety Act of 1990 and this law states that the food industry must do everything in its power to ensure that food in whatever processed form must be safe to eat. There are certain basic principles that can be applied by the individual to ensure that food is protected from bacteria. The core concept to be emphasised here is personal hygiene . Try to respect he following recommendations when you work with food:

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
