line extensions are changed forms of existing products. When a product is first launched it is often available in only one size and flavour, once the initial demand levels out the food company is able to maintain high production rates by offering other flavours of the product and different size or shape containers.

stick to 1st two topics for half yearly yeah?

Identify the 3 current developments in packaging

sorry been slacking a bit

Evaporation:
- method of increaing solid concentration by removing excess water/liquid
- liquid to steam/vapour/gas
- rasied to bp+
- requires, evaporation basin/vessel, heat, condenser, method of removing vapour.
- concentrates are made by this process

Explain the canning process making detailed reference to hydrostatic retort

The Food Technology in Action 2nd edition has this definition:
Quality control is the process by which we measure characterisitics, compare them to a standard and act on any differences that may occur.

This means that when food is being manufactured, there are quality control checks to ensure that the food is processed how it should be and that all products are the same. For example cooking a cake on a production line, there would be the same amount of each ingredient in each batch, the same size batches, the same cooking time for each batch of cakes. This ensures that all the cakes are exactly the same. These characterisitcs can be compared to a standard, such as 180 degress C for the oven temp.

Quality assurance is the cooperation to achieve quality control. It is all the parts of the company working together to maintain the quality of the products produced. This includes the management, factories, offices and individual departments.

I hope this helped.

guess what? new books next week :).

anyway with the canning...
Explain the canning process making detailed reference to hydrostatic retort
-cans filled w/ the food product and the air above the food is removed, using either steam or a vacuum chamber
- lid is placed on can and sealed
- filled cans heated in large pressure cookers (retorts) for the time required to kill the micro-organisms known to exist in the type of food being canned
- the can is then quickly cooled

starting temp is adjusted to produce a gas mix that will maximise shelf life

have you had your half yearly yet? hard/easy? did your teacher make it up or do you have an independant/catholic paper sent to the school?

yeah i thought it was about time to start this again i have had so many assessments all in a row.

nah haven't had my half yearly yet, week 9 for me on the friday and thankfully no-weighting, just using it to see how we are going. But our assessment is huge!!!!!!!!! But almost done.

The principles of food preservation are to control what 6 things? (we have only been taught 5)
1, water availability
2, addition of chemicals
3, temperature
4, the pH level
5, the oxygen level

what is the 'cradle to grave' analysis of packaging cost? Identify and briefly outline each step.

Cradle to grave is the opposite of cradle to cradle

Describe the preservation processes of canning, drying, pasteurising, freezing and fermenting.
