Strategies for product development of new food part D

Question 1

what takes the most part of the work when developping a new product

Answer 1

product design (includes the process design)

Question 2

What is scale up

Answer 2

it is the changes that occur between the smaller laboratory or kitchen to a full scale manufacturing

Question 3

what are the two pathways to design the process for scale-up

Answer 3

1. theoretical modesl based on mathematical modeling 2. experiments and analysing date 3. mathematical simulation that is a combinaition of the two

Question 4

What are the main functions of the semi-production pilot plant?

Answer 4

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

Question 5

What are the different steps in the scale up?

Answer 5

1- conceptualization 2- preliminary engineering 3- final engineering 4- implementation 5- close out

Question 6

What can you define in the prelimineary engineering ?

Answer 6

-unit operations -pieces of equipment needed to be purchased - facility modification - changes in productiong and personnel - how new systems will impact current operations

Question 7

What do you do in the conceptualization of the scale up

Answer 7

• look at similarities/differences between the existing facilities - the feasibility of the scale up - identification of the need

Question 8

The analysis of risks consist of three components :

Answer 8

1- risk assessment 2- risk management 3- risk communication

Question 9

what are the three steps of the preliminary engineering ?

Answer 9

1- risk assessment 2- processing requirments 3- process development

Question 10

what are the problems you could encounter in the scale-up in the preliminary engineering?

Answer 10

• 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

Question 11

What are the two diagram you can do in the process development of the preliminary engineering step?

Answer 11

the block flow diagram the process flow diagram

Question 12

This diagram is done in the preliminary engineering step and is a detailed model of the steps

Answer 12

process flow diagram

Question 13

this diagram is done in the preliminary engineering step and the model is only representing the unit operations without further details

Answer 13

the block flow diagram

Question 14

what are the different parts of the quality function deployment

Answer 14

Question 15

what is the difference between a trademark and a tradename

Answer 15

tradename : name of the company
Trademark : only for goods and services

Question 16

what are the two main categories of food ingredients

Answer 16

1. Macrocomponents
2. microcomponents

Question 17

what is a food additive?

Answer 17

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.

Question 18

t or f : the food additive can be macrocomponent

Answer 18

true

Question 19

for what purpose food additives are not permitted

Answer 19

1. to mask faulty or inferior manufacturing practices
2. to deceive customers

Question 20

what is the processing aid ?

Answer 20

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
