Lesson 1Eggs and egg replacers: structure, foaming, colour, lecithin functionality and alternativesThis breaks down whole eggs, yolks, whites, their jobs in foaming, mixing fats, colour, structure, and checks shop egg replacers, plant proteins, lecithin options for cost, labels, performance.
Whole egg, yolk, and white functional rolesFoam formation, stability, and overrunEgg lipids and lecithin in emulsificationPasteurized and dried egg product handlingPlant-based egg replacers and labelingLesson 2How to interpret industrial ingredient labels and use 2–3 published formulas/labels to justify ingredient choicesThis teaches reading factory ingredient labels and matching to published sponge cake recipes, using 2-3 real cases to back each ingredient pick, amount, tech or rule role.

Native vs pregelatinized starch in battersModified starches for freeze–thaw stabilityPectin and locust bean gum for moistureMethylcellulose and thermal gelationOptimizing levels to avoid gumminessLesson 4Sugars and humectants: sucrose, invert sugars, sorbitol/glycerol — roles in sweetness, moisture retention, and awThis checks sucrose, flipped sugars, glucose syrups, polyols like sorbitol, glycerol, their jobs in sweet taste, moisture hold, freeze point drop, water activity control, effects on texture, browning, shelf life.
Comparing sucrose, invert sugar, and glucose syrupHumectancy and softness over shelf lifeWater activity targets for safe sponge cakesEffects on Maillard browning and crust colorPolyols for reduced-sugar and diet productsLesson 5Wheat flour: grades, protein content, enzyme activity and effects on structureThis details wheat flour sorts for cakes, ash, protein levels, gluten quality, built-in enzymes, how they shape batter thickness, gas hold, crumb fineness, cake size, tenderness.
Cake vs all-purpose vs bread flour selectionProtein quality, gluten strength, and tendernessDamaged starch and water absorption in battersAmylase activity, sugar release, and browningFlour testing data and supplier specificationsLesson 6Preservatives and clean-label alternatives: sorbates, propionates vs. low-additive strategies (acidity, humectants, packaging)This compares sorbates, propionates to low-add strategies like pH watch, humectants, packaging, hygiene, to build preservative setups balancing safety, shelf life, clean labels.
Sorbates and propionates: modes of actionpH, aw, and hurdle technology in cakesRole of humectants in mold controlPackaging, MAP, and oxygen managementDesigning clean-label preservation plansLesson 7Example sponge cake formula in baker's percentages with rationale for each levelThis builds full sponge cake recipe in baker’s percentages, target quality, why each amount, adjust for textures, lines, shelf life aims.
Target product profile and quality attributesBase flour, sugar, fat, and egg percentage rangesAdjusting water and liquids for batter viscosityBalancing leavening with batter strengthScaling formulas and checking baker’s mathLesson 8Leavening systems: chemical (sodium bicarbonate/acidulants), aeration strategies, and gas retentionThis looks at chemical rising for sponge cakes, bicarb, acidulants, how air methods, batter flow control gas release, pH, colour, volume.
Sodium bicarbonate and choice of acidulantsSingle-acting vs double-acting systemspH control, color, and flavor side effectsMechanical aeration and batter overrunGas retention and collapse preventionLesson 9Salt, flavours, and optional inclusions: salt function, vanilla and natural flavours, inclusions impact on shelf lifeThis explains salt, vanilla, natural tastes, inclusions like choc chips, nuts, fruits, focus flavour balance, water activity change, structure hit, microbe stability.
