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:

Questions & Answers

What is price elasticity of demand and its degrees. also explain factors determing price elasticity of demand?
Yutansh Reply
Price elasticity of demand (PED) is use to measure the degree of responsiveness of Quantity demanded for a given change on price of the good itself, certis paribus. The formula for PED = percentage change in quantity demanded/ percentage change in price of good A
GOH
its is necessarily negative due to the inverse relationship between price and Quantity demanded. since PED carries a negative sign most of the time, we will usually the absolute value of PED by dropping the negative sign.
GOH
PED > 1 means that the demand of the good is price elasticity and for a given increase in price there will be a more then proportionate decrease in quantity demanded.
GOH
PED < 1 means that the demand of the good is price inelasticity and for a given increase in price there will be a less then proportionate decrease in quantity demanded.
GOH
The factors that affects PES are: Avaliablilty of close substitutes, proportion of income spent on the good, Degree of necessity, Addiction and Time.
GOH
Calculate price elasticity of demand and comment on the shape of the demand curve of a good ,when its price rises by 20 percentage, quantity demanded falls from 150 units to 120 units.
Helen Reply
5 %fall in price of good x leads to a 10 % rise in its quantity demanded. A 20 % rise in price of good y leads to do a 10 % fall in its quantity demanded. calculate price elasticity of demand of good x and good y. Out of the two goods which one is more elastic.

Sosna Reply
consider two goods X and Y. When the price of Y changes from 10 to 20. The quantity demanded of X changes from 40 to 35. Calculate cross elasticity of demand for X.
Sosna
sorry it the mistake answer it is question
Sosna
consider two goods X and Y. When the price of Y changes from 10 to 20. The quantity demanded of X changes from 40 to 35. Calculate cross elasticity of demand for X.
Sosna
The formula for calculation income elasticity of demand is the percent change in quantity demanded divided by the percent change in income.

if the demand function is q=25-4p+p² 1.find elasticity of demand at the point p=5?

what are some of the difference between monopoly and perfect competition market
Obeng Reply
n a perfectly competitive market, price equals marginal cost and firms earn an economic profit of zero. In a monopoly, the price is set above marginal cost and the firm earns a positive economic profit. Perfect competition produces an equilibrium in which the price and quantity of a good is economic
Naima
what are some characteristics of monopoly market
Obeng Reply
explicit cost is seen as a total experiences in the business or the salary (wages) that a firm pay to employee.

what is monopoly
Peter Reply
what is taxation
Peter
is the compulsory transfer of wealth from the private sector to the public sector
Jonna
why do monopoly make excess profit in both long run and short run
Adeola Reply
because monopoly have no competitor on the market and they are price makers,therefore,they can easily increase the princes and produce small quantity of goods but still consumers will still buy....

Gladys
process of production
Mutia
Basically factors of production are four (4) namely: 1. Entrepreneur 2. Capital 3. Labour and; 4. Land but there has been a new argument to include an addition one to the the numbers to 5 which is "Technology"
