Culinary Techniques Questions
A
Correct answer
Explanation
Cooking meat, especially through slow and moist methods, helps break down tough collagen fibers into gelatin. This process softens the connective tissues, making the meat much more tender and easier to chew.
-
Storing foods away from light and heat.
-
Cutting, grating or squeezing fruits and vegetables.
-
Using only a small amount of water to cook them in.
-
Boiling vegetables for a long time until soft.
D
Correct answer
Explanation
Boiling vegetables for a long duration in a large amount of water causes water-soluble vitamins (such as Vitamin C and B-group vitamins) to leach out and be destroyed by heat. To preserve nutrients, cooking methods should use minimal water and shorter cooking times, such as steaming or microwaving.
-
think carefully before doing something serious
-
wise people often have the same ideas
-
it’’s not good to have lots of people in the kitchen
-
too many helpers can get in each other’s way
D
Correct answer
Explanation
When too many people try to work on the same project or task, it often leads to confusion and a poor final result. Each person may have a different idea, causing conflict and inefficiency. Therefore, having too many helpers can get in each other's way.
-
Heat treatment of milk.
-
Descaling and gutting fish.
-
Peeling, slicing and canning fruit.
-
Making pasta from wheat flour.
D
Correct answer
Explanation
Secondary processing involves turning primary processed ingredients into new food products. Making pasta from wheat flour is a secondary process, whereas the other options are primary processing steps.
-
Milling wheat to make flour.
-
Making cakes from flour, fat and sugar.
-
Making margarine from oil
-
Making jam from fruit and sugar
A
Correct answer
Explanation
Primary processing involves converting raw food materials into a form that can be eaten or used in further food production. Milling wheat into flour is a classic example of primary processing, while the other options involve secondary processing where ingredients are combined to create new products.
-
Plasticity
-
Emulsification
-
Aeration
-
Shortening
D
Correct answer
Explanation
Shortening is the process of coating flour particles with fat, which prevents the formation of long gluten strands. This results in a crumbly or tender texture in baked goods, rather than a chewy or elastic one.
-
Making butter by churning cream
-
Removing feathers and internal organs of poultry
-
Pasteurisation of milk
-
Squeezing fruits to make fruit juices
A
Correct answer
Explanation
Primary food processing involves the initial preparation of raw materials. Churning cream into butter is a secondary process because it involves transforming a dairy product into a different food product, whereas the other options are initial preparation steps.
-
fire
-
bright light
-
microwave
-
stove
-
scrambled
-
fried
-
boiled
-
poached
C
Correct answer
Explanation
Hard-boiled eggs are the standard type of egg used for decorating and hunting during Easter celebrations.
-
The size of crystals formed from a solution.
-
The PH level of the food.
-
The proportion of amylose and amylopectin molecules.
-
The serving temperature.
A
Correct answer
Explanation
The size of crystals formed from a solution is not a factor in the thickening power of starch. PH level, amylose/amylopectin ratio, and temperature all significantly impact starch gelatinization and thickening.
-
when a starch mixture is cooled too rapidly
-
when there is a high level of amylopectin
-
when there is extreme retrogradation
-
when thee is little or no retrogradation
C
Correct answer
Explanation
Syneresis is the expulsion of liquid from a gel, which occurs when the starch molecules bond too tightly together during retrogradation. Extreme retrogradation leads to this contraction and water release.
-
Acid, sugar, and water.
-
Calcium, sugar, and water.
-
Cellulose, sugar, and water.
-
Sugar, water, and xanthan gum.
A
Correct answer
Explanation
Pectin gelation requires a specific balance of pectin, acid, and sugar (which acts as a dehydrating agent) in an aqueous environment.
-
Adding acid.
-
Heating to the gelatinization point.
-
Reducing salt content.
-
Reducing water content.
A
Correct answer
Explanation
Acid hydrolyzes starch molecules during heating, breaking them down into smaller chains and thereby reducing their ability to thicken the mixture.
-
amylopectins
-
amylose
-
branched polymers
-
linear sugars
B
Correct answer
Explanation
Amylose is a linear molecule that packs tightly and provides significant thickening power when heated in water. Amylopectin is branched and generally provides less thickening power than amylose.
-
amylose
-
carbohydrate gum
-
cellulose
-
pectin
A
Correct answer
Explanation
Amylose is a linear starch component that helps create a firm, cohesive structure when cooked, making it useful for binding batters to food during frying.
