Pass Ratio : 100%
Without which of the given steps, would ice cream be an inedible hard frozen mass?
Freezing
Whipping with air
Hardening of ice cream
All of the mentioned
Explanation:
Whipping the ice-cream after a portion of it has been frozen is a very important step otherwise the ice cream would just be a hard frozen inedible mass like ice.

Which of the following indicators has a graduated scale?
Defrost
Time-temperature integrators
Time-temperature integrators/indicators
All of the mentioned
Explanation:
Time-temperature integrators/indicators have a graduated scale. They start to react as soon as the activated temperature is reached. Defrost indicators are set to a temperature when the frozen food gets spoiled/starts de freezing. Time-temperature integrators react as soon as they’re activated to the preselected time and temperature.

Which of the following risk is associated with a frozen material tagged ‘00+’?
Contains a sensitive element that might be damaged with poor care
Is prone to harmful bacteria if not maintained at the instructed conditions
Chances of spoiling to take place by the mishandling of consumers
All of the mentioned
Explanation:
‘00+’ means that there are chances of spoiling to take place by the handling of consumers. The fact that the first two symbols are a 0, the risks of it containing a sensitive element that might be damaged with poor care and that it is prone to harmful bacteria if not maintained at the instructed conditions are negligible.

Use of fish for battering with sauce comes under which of the following categories of processes?
Single component, single-product process
Multi component blended products
Multi component products with add-ons
Multi component, multi process assembly operations
Explanation:
Use of fish for battering comes under the category of multi component products with add-ons. The sauce is the add-on.

Which of the following steps in making ice-cream is not present?
Adding liquid materials to batch
Add solids to batch and stir it and mix till dispersed in a liquid
Add sugar at high temperatures but before pasteurization
None of the mentioned
Explanation:
All of the mentioned are the correct steps in making of ice cream.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: The step of freezing of ice cream can be done by both continuous and batch process.
True, False
True, True
False, False
False, True
Explanation:
The step of freezing of ice cream can be done by both continuous and batch process. Hardening is a separate process in the making of ice cream. After freezing, the mix is kept in a separate room for hardening at low temperatures.
Question 7

Pass Ratio : 100%
Frozen prepared chicken dinner comes under which of the following categories of processes?
Single component, single-product process
Multi component blended products
Multi component products with add-ons
Multi component, multi process assembly operations
Explanation:
Frozen prepared chicken dinner comes under multi component, multi process assembly operations.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
Holding time for pasteurization is more in continuous than that in batch pasteurization.
True
False
Explanation:
Holding time for pasteurization is more in batch than that in continuous pasteurization. This is because HTST- high temperature short time is used in continuous whereas in batch operations, the exposure time is almost half an hour.
Question 9

Pass Ratio : 100%
Which of the following change takes place during the ageing process in the making of ice creams?
Decrease in viscosity
Proteins change slightly
Fats turn into liquids
All of the mentioned
Explanation:
During the aging process of ice cream making, the viscosity increases, proteins change slightly and fats turn into solids.
