Strategies for product development of new food part D Flashcards
what takes the most part of the work when developping a new product
product design (includes the process design)
What is scale up
it is the changes that occur between the smaller laboratory or kitchen to a full scale manufacturing
what are the two pathways to design the process for scale-up
- theoretical modesl based on mathematical modeling 2. experiments and analysing date 3. mathematical simulation that is a combinaition of the two
What are the main functions of the semi-production pilot plant?
1-provide design criteria for larger equipment and utilities 2- more accurate than theoritical calculations 3-small amounts of food may be used for consumer trials and test marketing
What are the different steps in the scale up?
1- conceptualization 2- preliminary engineering 3- final engineering 4- implementation 5- close out
What can you define in the prelimineary engineering ?
-unit operations -pieces of equipment needed to be purchased - facility modification - changes in productiong and personnel - how new systems will impact current operations
What do you do in the conceptualization of the scale up
- look at similarities/differences between the existing facilities - the feasibility of the scale up - identification of the need
The analysis of risks consist of three components :
1- risk assessment 2- risk management 3- risk communication
what are the three steps of the preliminary engineering ?
1- risk assessment 2- processing requirments 3- process development
what are the problems you could encounter in the scale-up in the preliminary engineering?
- emulsification breakdown and solid stratification - thixotropic fluid ( decrease in viscosity when time mixing increases ) - dispersion of ingredients inside might be not uniform - the incorporation of air might be different
What are the two diagram you can do in the process development of the preliminary engineering step?
the block flow diagram the process flow diagram
This diagram is done in the preliminary engineering step and is a detailed model of the steps
process flow diagram
this diagram is done in the preliminary engineering step and the model is only representing the unit operations without further details
the block flow diagram
what are the different parts of the quality function deployment
what is the difference between a trademark and a tradename
tradename : name of the company
Trademark : only for goods and services
what are the two main categories of food ingredients
- Macrocomponents
- microcomponents
what is a food additive?
food that is not naturally present that is added to the food to be part of it to give caracteristics. Table division 16 will give you the food additives.
t or f : the food additive can be macrocomponent
true
for what purpose food additives are not permitted
- to mask faulty or inferior manufacturing practices
- to deceive customers
what is the processing aid ?
additives that don’t appear on the label because it is used in the manufacturing but it is not a substance that becomes part of the food. one example would be washing foods with chlorinate water
