QCAA Food & Nutrition General Senior Syllabus (2025 v1.3)

Comprehensive vocabulary flashcards covering the core concepts, food science terminology, food system principles, problem-solving phases, and assessment criteria of the QCAA Food & Nutrition General Senior Syllabus (2025 v1.3).

Problem-solving process in Food & Nutrition

An iterative four-phase process comprising Explore, Develop, Generate, and Evaluate and refine, used to move from an identified problem to a recommended food solution.

The food system

A cyclical network consisting of five core sectors—production, processing, distribution, consumption, and research and development—overarched by the principles of protection, sustainability, and waste management.

Food & Nutrition

The study of food in the context of food science, nutrition and food technologies, where students explore the chemical and functional properties of nutrients to create solutions that maintain beneficial nutritive values.

Protection (food system principle)

An overarching principle that involves protecting the food supply from contamination by food-borne illness and other foreign materials or chemicals during production, processing, distribution, and storage.

Explore phase

The phase of the problem-solving process where students investigate needs, constraints, or requirements to analyse a food and nutrition problem and determine success criteria.

Develop phase

The phase of the problem-solving process where students research knowledge and processes, synthesise information and data, and evaluate ideas against success criteria to determine a solution.

Generate phase

The phase of the problem-solving process where students produce prototypes that, when tested, provide primary data to determine the feasibility of a food and nutrition solution.

Evaluate and refine phase

A critical, ongoing phase in which students appraise ideas and solutions against success criteria and data to make modifications, improvements, and justified recommendations.

Success criteria

Pre-determined standards addressing stakeholder needs, food science and safety principles, constraints, and wider impacts used to evaluate the feasibility and quality of a food solution.

Bioavailability

The degree and rate at which administered nutrients are absorbed and become available for physiological use in the body, which can be altered by food processing and cooking methods.

Descriptive sensory profiling

A sensory testing methodology used to evaluate whether a specific consumer group likes or prefers a product and to map out sensory differences using structured panels.

Rating or likeability test

A sensory evaluation test in which panellists sample a food product and score their preference on a nine-point hedonic scale ranging from 'dislike extremely' to 'like extremely'.

Lexicon

A standardized vocabulary of descriptive sensory terms that provides a communication tool for sensory panels, drives questionnaire design, and ensures product consistency.

Denaturation

The structural alteration of protein molecules through the breaking of secondary and tertiary bonds, triggered by heat, acid/alkali changes, or physical manipulation like foam formation.

Coagulation

The permanent transformation of denatured protein molecules from a liquid or soluble state into a solid or semi-solid gel-like clot through heat, acids, enzymes (e.g. rennin), or salts.

Maillard reaction

A chemical reaction between amino acids and reducing sugars that occurs under dry heat, producing non-enzymatic browning and complex savoury flavours.

Consumer demand

The willingness and ability of consumers to purchase particular goods and services, driving the commercial range, formulation, and development of food products.

Consumer food drivers

Influential factors that guide purchasing decisions, categorized into convenience, budget, perceived quality, and ethics or culture.

Triangle test

A discriminative sensory testing method where panellists evaluate three samples (two identical, one different) to identify whether a detectable difference exists between products.

Duo-trio test

A discriminative sensory test where panellists are presented with an identified control and two coded samples to determine which coded sample is identical to the control.

Hazard Analysis Critical Control Points (HACCP)

A preventive food safety system that identifies, evaluates, and controls biological, chemical, and physical hazards across all stages of the food supply chain.

Critical Control Points (CCPs)

Specific stages or procedures in a food manufacturing or handling process where control measures can be applied to eliminate, prevent, or reduce a food safety hazard to an acceptable level.

Food Standards Australia New Zealand (FSANZ)

The statutory bi-national government agency responsible for developing and administering the Food Standards Code, which regulates labelling, safety, and nutritional claims.

Food formulation

The deliberate combining of specific ingredients in appropriate ratios and structural arrangements according to a precise formula to yield a targeted food product.

Gelatinisation

The thermal swelling and eventual disruption of starch granules in the presence of water and heat, forming a viscous paste or gel across three distinct stages.

Crystallisation

A food processing technique used to separate and solidify a dissolved solute from a solution by forming solid, organized crystal structures.

Nucleation

The initial physical stage in crystallisation where molecules dissolved in a solution, liquid, or vapour aggregate into stable clusters that form crystal nuclei.

Caramelisation

The non-enzymatic browning and flavour development that occurs when sugar is subjected to high dry heat, causing thermal decomposition and oxidation.

Dextrinisation

The chemical breakdown of long-chain starch polysaccharides into shorter-chain dextrins or disaccharides under dry heat, causing browning and a sweeter taste.

Gelification

The chemical transformation of a liquid food into a stabilized, solid or semi-solid gelatinous structure using hydrocolloids or gelling agents such as agar-agar, pectin, or gelatine.

Leavening

The biological, chemical, or physical expansion of gas bubbles in batters and doughs that causes rising and creates a porous, aerated crumb structure in baked goods.

Retrogradation

A chemical spoilage change in gelatinised starch gels where amylose and amylopectin chains realign and recrystallise upon cooling, leading to staling.

Syneresis

The undesirable expulsion or weeping of liquid from a coagulated protein or gelatinised starch gel caused by continued contraction of the molecular network.

Dispersed system (emulsion)

A two-phase system where one immiscible liquid is dispersed as droplets throughout another liquid, commonly existing as oil-in-water or water-in-oil systems.

Emulsifier

A substance possessing both hydrophilic and lipophilic properties that reduces surface tension between two immiscible liquids to stabilize an emulsion.

Spherification

A culinary technique that shapes a liquid food into pliable spherical pearls or caviar-like spheres using a controlled chemical gelling reaction.

Rancidity

The chemical spoilage and deterioration of fats and oils caused by oxidation or enzymatic hydrolysis, resulting in unpleasant flavours and unpalatable odours.

Nutrition Consumer Market (NCM)

A designated market segment of individuals or population groups who purchase food products, goods, and services tailored to specific dietary, physiological, or health needs.

Nutrient Profiling Scoring Criterion (NPSC)

A nutrient profiling point-system established under the FSANZ Food Standards Code that classifies foods to determine their eligibility to carry health level claims.

Reformulation

The scientific modification of an existing food recipe's components or processing techniques to optimize nutritional attributes—such as reducing salt, sugar, or fat—while preserving sensory quality.

Chronic disease

A broad classification of long-lasting, persistent medical conditions—including type 2 diabetes, obesity, and coronary heart disease—that create specific nutritional and dietary management demands.
