Food Processing Flashcards
Why is food processed
Reduces meal prep time
Makes food available out of season
Preserves food
Makes safer to eat
What are the 3 food production stages
Input
Process
Output
What is white flour
Made from on,y endosperm
What is whole meal flour
Made from all parts of grain
Brown flour
Some bran and germ have been removed
What is primary processing
When food needs processed before eaten
What is secondary processing
When food that undergone primary processing is transformed into a food product
What are the production stages in milk processing
Milking
Storing
Pasteurisation
Seperation
Homogenisation
What is milking
The milking of a cow to collect its milk
What is storing in milk production
Milk stored in a huge 4 degree vat
What is pasteurisation
Process in which milk is heated to high temp for short time to kill bacteria
Separation what is it in milk production
Separated into cream and liquid
What is homogenisation in milk production
Ensures milk has an even consistency milk is pushed through hole so fat molecules are broken down
What is the first step in cheese production
Milk is pasteurised to kill germs then cooled vastly and pumped into cheese vats
What is rennet
An enzyme added to milk to separate into thick curds and runny whey
Second step in cheese production
Rennet is added to milk as it separates it into thick curds and runny whey
What is a curd
Solid part of milk used to make cheese
What is whey
The liquid by product of cheese making
Third step of cheese production
Curds are cut which helps realise whey
Fourth step of cheese production
Curds and whey are heated and stirred
5th step in cheese production
Curds are stacked and cut and toned to release more whey
3 reasons why salt is added to cheese
Slows germ growth
Helps develop rind
Helps expel whey
