1During starch gelatinisation in an aqueous mixture, at what stage does maximum swelling of starch granules occur and what molecular event drives gel formation upon cooling?
A.Granules swell at 60-80°C as hydrogen bonds break; upon cooling, leached amylose chains re-associate to form a continuous three-dimensional network.
B.Granules swell at 100°C as covalent peptide bonds break; upon cooling, amylopectin crystallizes into an insoluble precipitate.
C.Granules shrink at 50°C due to water evaporation; upon cooling, lipids encapsulate starch to form a solid mass.
D.Granules dissolve completely at 40°C via enzymatic hydrolysis; upon cooling, fructose polymerizes into a dense matrix.
Explanation: Starch gelatinisation occurs when heating starch in water (typically 60-80°C), causing hydrogen bonds to break so water penetrates and swells the granules. As amylose leaches out into the aqueous phase and the mixture cools, amylose molecules align and re-form hydrogen bonds, trapping water within a gel matrix.
2What chemical process occurs when dry wheat flour is toasted, resulting in a brown color, reduced thickening power, and a nutty flavor?
A.Caramelisation of monosaccharides
B.Dextrinisation of starch polymers
C.Enzymatic browning of polyphenols
D.Saponification of triglycerides
Explanation: Dextrinisation is the breakdown of starch molecules into shorter-chain polysaccharides called pyrodextrins when subjected to dry heat. Because the starch chains are shortened, toasted flour loses much of its ability to gelatinise and thicken liquids, while developing a brown color and characteristic flavor.
3Which component of egg yolk acts as a natural amphiphilic emulsifier to stabilize mayonnaise, an oil-in-water emulsion?
A.Ovalbumin
B.Vitellin
C.Lecithin (phosphatidylcholine)
D.Avidin
Explanation: Lecithin is a phospholipid present in egg yolk containing both a hydrophilic (water-attracting) phosphate head and lipophilic (fat-attracting) fatty acid tails. This amphiphilic structure positions lecithin at the interface of oil droplets and vinegar, reducing interfacial tension and preventing phase separation.
4When liquid egg whites are heated, they transform into a solid white gel. What structural protein transition causes this change?
A.Starch retrogradation and syneresis
B.Enzymatic cleavage of disulfide bonds
C.Lipid autoxidation and cross-linking
D.Protein denaturation followed by coagulation
Explanation: Thermal energy disrupts the non-covalent secondary and tertiary structures of egg white proteins (denaturation), causing polypeptide chains to unfold. Exposed hydrophobic amino acids then interact and form a rigid, three-dimensional cross-linked network that traps water (coagulation).
5Upon standing or freezing, a cooked starch sauce may expel liquid and become watery. What is the technical term for this weeping phenomenon?
A.Emulsification
B.Dextrinisation
C.Syneresis
D.Hydrolysis
Explanation: Syneresis is the release of liquid from a gel matrix. In starch gels, retrogradation occurs during storage as linear amylose molecules progressively realign and form hydrogen bonds, contracting the gel network and squeezing out bound water.
6Why does dipping freshly sliced apples into lemon juice effectively prevent surface browning?
A.Lemon juice contains sucrose, which coats the apple and blocks water absorption.
B.The low pH of citric acid in lemon juice inhibits polyphenol oxidase enzyme activity, while ascorbic acid acts as a reducing agent.
C.Lemon juice introduces calcium ions that strengthen pectin cell walls against cellular leakage.
D.The high temperature of lemon juice thermalizes phenolic substrates before oxygen contact.
Explanation: Enzymatic browning occurs when polyphenol oxidase (PPO) oxidizes phenolic compounds into o-quinones in the presence of oxygen. Lemon juice lowers the surface pH below PPO's optimal range (pH 6-7) and provides ascorbic acid, which reduces quinones back to colorless diphenols.
7What is the primary difference between hydrolytic rancidity and oxidative rancidity in edible fats?
A.Hydrolytic rancidity requires UV light, whereas oxidative rancidity requires microbial enzymes.
B.Hydrolytic rancidity affects saturated fats only, whereas oxidative rancidity affects water-soluble vitamins.
C.Hydrolytic rancidity releases free fatty acids via lipase action or heat in the presence of water, whereas oxidative rancidity involves oxygen reaction with unsaturated double bonds.
D.Hydrolytic rancidity produces solid polymers, whereas oxidative rancidity produces neutral sugar syrups.
Explanation: Hydrolytic rancidity occurs when moisture and enzymes (lipases) or heat break ester bonds in triacylglycerols, releasing free fatty acids (e.g., butyric acid in butter). Oxidative rancidity is a free radical autoxidation chain reaction where atmospheric oxygen attacks double bonds in unsaturated fatty acids, yielding volatile aldehydes and ketones.
8Which hydrocolloid ingredient is commonly added to commercial salad dressings as a thickener and stabilizer to prevent phase separation?
A.Sodium chloride
B.Ascorbic acid
C.Lactic acid
D.Xanthan gum
Explanation: Xanthan gum is an extracellular polysaccharide produced by fermentation of Xanthomonas campestris. It acts as a hydrocolloid thickener that imparts pseudoplastic (shear-thinning) rheology to pourable salad dressings, increasing continuous-phase viscosity to prevent oil droplet coalescence.
9Which chemical reaction sequence accounts for the brown crust, savory roasted aroma, and complex flavor profiles formed during the baking of bread?
A.Condensation of reducing sugars with amino groups, forming glucosylamines that undergo Amadori rearrangement to yield melanoidins.
B.Thermal pyrolysis of pure sucrose at 160°C producing caramelan, caramelen, and caramelin polymers.
C.Enzymatic oxidation of tyrosine by tyrosinase yielding insoluble melanin pigments.
D.Polymerization of free fatty acids with starch granules under alkaline pH conditions.
Explanation: The Maillard reaction is a non-enzymatic browning cascade initiating between the carbonyl group of a reducing sugar (e.g., glucose) and the free amino group of an amino acid or protein (e.g., lysine). The intermediate Amadori or Heyns rearrangement products undergo further dehydration, fragmentation, and Strecker degradation to produce flavor volatiles and brown melanoidin polymers.
10During deep-fat frying, commercial oil gradually degrades. Which oil quality parameter decreases significantly, indicating oil breakdown?
A.Viscosity of the frying oil
B.Smoke point temperature
C.Peroxide value of degraded oil
D.Free fatty acid content
Explanation: As frying oil degrades due to heat, water from food, and oxygen exposure, triglycerides hydrolyze into free fatty acids (FFAs) and small volatile compounds. Accumulated FFAs volatilize at much lower temperatures, significantly reducing the oil's smoke point and causing smoke emission at standard frying temperatures.
