Question 89: What does 'specific gravity' measure in cake doughnut batter production?

The density of the batter relative to water, indicating aeration level (Correct answer)
The weight of oil absorbed during frying
The temperature at which batter sets
The ratio of flour to liquid in the recipe

Correct answer: The density of the batter relative to water, indicating aeration level

Specific gravity compares batter density to water; a lower value means more air has been incorporated, directly affecting texture and volume.

Question 90: What personal hygiene practice is critical in food handling?

Wearing jewelry.
Wearing open shoes.
Using perfumes.
Regular handwashing (Correct answer)

Correct answer: Regular handwashing

Regular handwashing is the most critical personal hygiene practice in food handling as it removes transient microorganisms that can cause illness. Hands are constantly in contact with various surfaces and ingredients, making them a primary vehicle for germ transmission. Frequent and proper handwashing significantly reduces the risk of contaminating food products.

Question 91: Which mixing method is typically used to develop gluten structure in yeast-raised doughnut dough?

Intensive kneading or spiral mixing (Correct answer)
Creaming fat and sugar first
