VCE Food Studies cheat sheet

Food origins classification: plant foods (cereals, pulses, fruits, vegetables, nuts) versus animal foods (meat, poultry, fish, eggs, dairy); fungi such as mushrooms form a separate group.

Cereal grains share a structure of bran (outer fibre-rich layer), endosperm (starch and protein store) and germ (fat, vitamins, minerals); milling removes bran and germ, lowering fibre.

Pulses are dried legume seeds (lentils, chickpeas, dried beans); they supply plant protein, dietary fibre and B-group vitamins, and traditionally require soaking before cooking.

Cultural influences on Australian food patterns include Indigenous Australian food knowledge, British colonisation, postwar migration from Europe, and later Asian and Middle Eastern migration.

Indigenous Australian food practices include seasonal harvesting, fire-stick farming to regenerate plant growth, and use of native foods such as quandong, wattleseed, finger lime and bush tomato.

Food choice determinants fall into physical (hunger, appetite, access, cost), social (family, peers, culture, religion) and psychological (mood, habits, values, knowledge) categories.

The Australian Guide to Healthy Eating is a food-selection guide with five food groups plus discretionary choices; it is a guide to proportions, not a rigid menu.

Meals in Australia have shifted toward grazing and snacking, more meals eaten away from home, and greater use of convenience and pre-prepared foods.

A food system spans production (farming, fishing), processing, distribution/retail, consumption and waste disposal; each stage has environmental, economic and social effects.

Food processing levels: minimal (washing, cutting), primary (milling, freezing, canning), and ultra-processed (reconstituted products with additives, e.g. flavoured snacks and soft drinks).

Preservation principles: heat destroys microorganisms; low temperature slows growth; drying and salting reduce available water; acid lowers pH; vacuum packaging removes oxygen.

Food safety: the temperature danger zone is 5°C to 60°C; high-risk foods are moist, protein-rich foods such as cooked meat, dairy and seafood.

Food waste occurs at household, retail and production levels; reduction strategies include meal planning, correct storage, using leftovers and composting.

Food security means reliable physical and economic access to sufficient, safe, nutritious food; it is affected by income, location, transport and emergency disruption.

Sustainable food choices consider food miles, seasonality, packaging, water and energy use, animal welfare and fair returns to producers.

Food labelling in Australia requires a nutrition information panel, ingredient list in descending order by weight, allergen declarations and country-of-origin information.

Macronutrients: carbohydrates (16 kJ/g), protein (17 kJ/g), fats (37 kJ/g), alcohol (29 kJ/g); energy is expressed in kilojoules (1 kcal ≈ 4.2 kJ).

Protein is built from amino acids; animal proteins generally supply all essential amino acids, while most plant proteins are limiting in one or more, so combining foods improves protein quality.

Carbohydrates: monosaccharides (glucose, fructose), disaccharides (sucrose, lactose) and polysaccharides (starch, glycogen, fibre); fibre resists human digestion and supports bowel health.

Fats: saturated (mostly animal, solid at room temperature), monounsaturated and polyunsaturated (plant and fish oils); trans fats form through partial hydrogenation.

Micronutrients: fat-soluble vitamins A, D, E and K require dietary fat for absorption; water-soluble B-group and C are not stored in large amounts and are lost in cooking water.

Key minerals: calcium and phosphorus for bone; iron for haemoglobin (haem iron from meat is better absorbed than non-haem plant iron); iodine for thyroid function; sodium for fluid balance.

Functional properties of food: gelation (starch thickening, setting of pectin), emulsification (lecithin in egg yolk), aeration (egg white foam), denaturation (heat, acid, mechanical action) and caramelisation.

Maillard browning occurs between amino acids and reducing sugars under dry heat, producing brown colour and flavour; it differs from caramelisation, which involves sugars alone.

Ethical concerns in food production include animal welfare, fair trade and producer income, genetic modification, labour practices and environmental impact.

Genetically modified foods involve inserting or altering genes to gain traits such as pest resistance or improved shelf life; regulation in Australia is by the Gene Technology Regulator, and labelling is required for GM content.

Food fortification adds nutrients to restore or increase levels (e.g. iodised salt, folic acid in bread flour); supplementation delivers nutrients as tablets or doses.

Marketing influences food choice through advertising, packaging, health claims and placement; persuasive techniques include celebrity endorsement, cartoon characters and premium health imagery.

Health claims on food labels are regulated; nutrient content claims (e.g. 'low fat') must meet defined thresholds, and therapeutic claims require evidence approval.

Emerging food technologies include plant-based meat analogues, cultured (cell-based) meat, insect protein and precision fermentation; each raises questions of cost, acceptance and sustainability.

The triple bottom line evaluates food enterprises on economic, social and environmental outcomes rather than profit alone.

Food citizenship describes consumers acting on values such as sustainability and equity when choosing and advocating about food.
