Which of the following best describes sensory food evaluation?

• it is a process where we eat food to understand the different taste

In a food evaluation process, it is recommended to label food samples with

• wrong names e.g. cookies instead of cupcakes

• specific descriptive terms e.g. 25g sugar cupcakes

• random numbers e.g. 345, 232, 114

it is important to have the same portion served for each sample because

• different amount may not look aesthetically pleasing

• different amount may affect the appetite of the tester

• different amount served may affect judgement of the tester

• different amount may incur wastage of the food product served

During the testing of food, there should be no

• talking with others

• asking for a spoon

• having a glass of water by the side

• rinsing of palette after each testing

Testing of food is done in isolation so as to

• ensure fairness of testing

• reduce the amount of food served

• allow more concentration during testing

• reduce the crowd during testing

• collated testing
