English:Raw Materials in the Bakery Trade
Raw Materials in the Bakery Trade
Introduction
Raw Materials in the Bakery Trade introduces the ingredients and ingredient systems that professional bakers receive, assess, store, scale, process, and document every day. In vocational training, you need more than a list of ingredients: you need to understand how raw-material properties influence dough, batter, fermentation, machinability, baking loss, crumb structure, crust colour, flavour, shelf life, food safety, allergen management, and production costs.
A bakery formula is a controlled technical system. Flour quality, water absorption, yeast activity, salt level, sugar concentration, fat plasticity, egg functionality, dairy solids, cocoa characteristics, seed hydration, and the activity of enzymes or chemical leaveners can all change the process. The professional task is therefore to connect specification → function → process → product quality.
By the end of this aiMOOC, you should be able to:
- Interpret raw-material specifications: Connect measurable properties with bakery performance.
- Explain ingredient functionality: Describe why ingredients are used, not only what they are called.
- Calculate baker's percentages: Scale formulas and compare formulations accurately.
- Evaluate incoming materials: Use sensory checks, supplier documentation, lot identification, and storage requirements.
- Control allergens and cross-contact: Apply bakery-specific hygiene and segregation practices.
- Diagnose production faults: Distinguish ingredient-related causes from process-related causes.
The Professional View of Raw Materials
In bakery production, a raw material is judged by four linked criteria: identity, quality, functionality, and fitness for the intended process. Two flours can both be legally sold as wheat flour but behave differently in a spiral mixer, divider, laminator, retarder-proofer, or high-speed bread line. Likewise, two fats can contain similar amounts of lipid but differ strongly in plasticity and melting behaviour.
Professional control begins with an approved specification. Depending on the material and operation, the specification may include moisture, protein, ash or mineral content, particle size, microbiological limits, enzyme activity, fat content, acidity, colour, allergen status, packaging, shelf life, storage temperature, and permitted processing aids. You should compare deliveries with the current specification rather than relying only on appearance.
A useful decision sequence is:
- Receive: Check supplier, material identity, packaging integrity, lot or batch code, quantity, and required temperature.
- Verify: Compare the delivery with the specification and inspect representative material where your procedure requires it.
- Record: Keep the documentation needed to trace a raw material into finished products.
- Store: Protect the material from moisture, heat, light, pests, odours, contamination, and allergen cross-contact.
- Rotate: Use the stock-rotation rule required by your bakery, often FEFO for dated materials.
- Scale accurately: Follow the current formula and dosing tolerances, especially for salt, yeast, leaveners, improvers, enzymes, colours, and flavours.
Cereals, Flour and Milling Products
Wheat Flour
Wheat flour is the structural basis of many breads, rolls, cakes, biscuits, laminated products, and pastries. The functional behaviour of wheat flour depends on the wheat variety, growing conditions, milling extraction, particle characteristics, protein quantity and quality, damaged starch, endogenous enzymes, moisture, and storage conditions.
When wheat flour is hydrated and mixed, the storage proteins gliadin and glutenin contribute to the formation of gluten. In simplified production terms, gliadin contributes extensibility and glutenin contributes strength and elasticity. The resulting gluten network helps retain fermentation gases in many wheat doughs. Its useful strength depends on the product: a pan bread, baguette, pizza dough, croissant, sponge cake, and short biscuit do not require identical flour properties.
Professional flour assessment can include:
- Protein: A quantity measure that is useful but does not alone describe gluten quality.
- Ash or mineral content: An indicator related to milling extraction and flour classification in several countries.
- Falling Number: An indirect indicator of alpha-amylase activity and sprout-related enzyme activity.
- Farinograph data: Water absorption, dough development, and stability under standardized mixing conditions.
- Extensograph or alveograph data: Information about dough resistance, extensibility, or deformation behaviour.
- Damaged starch: A milling-related property that affects water absorption and enzyme accessibility.
- Moisture: Important for storage stability, legal compliance, and formula consistency.
A lower Falling Number generally indicates higher alpha-amylase activity. The practical target depends on the flour, process, product, and use of malt or enzymes, so you should follow the agreed specification rather than treating one number as universally ideal.
Flour Types and Ash Content
Flour classification is country-specific. In the German DIN system commonly encountered in Central European vocational bakery practice, a type number such as Type 550 is linked to the approximate mineral or ash content of the flour on a dry-matter basis. A higher type number generally indicates a higher mineral content and a greater contribution from outer grain layers. Do not transfer type numbers directly to another country's flour system without checking its standard.
For production, type designation is only one part of flour selection. A baker must also consider protein quality, water absorption, enzyme activity, granulation, sensory quality, and the required product profile.
Rye, Spelt and Oats
Rye is technologically different from wheat. Rye dough structure depends much more strongly on starch behaviour and water-binding arabinoxylans than on a wheat-like gluten network. Acidity is particularly important in many rye bread processes because it influences dough behaviour, flavour, microbial ecology, and the control of starch-degrading enzyme activity.
Spelt is a wheat species and contains gluten-forming proteins. Its dough behaviour can differ from common bread wheat, and overmixing or inappropriate hydration can reduce process stability. Flour specifications and practical dough tests are more useful than assumptions based only on the grain name.
Oat products contribute flavour, fibre, lipids, and characteristic water-binding components. Rolled oats, oat flour, and oat bran behave differently in dough. In products that must meet gluten-free requirements, ordinary oats are not automatically suitable because contamination with gluten-containing cereals is a major control issue; use materials certified for the relevant market and follow local requirements.
Wholemeal, Bran, Semolina and Other Milling Fractions
Wholemeal flour includes more of the grain components than refined flour and therefore changes water absorption, fermentation, dough handling, flavour, nutrient profile, and shelf-life behaviour. Bran particles can interfere physically with a continuous gluten network and also bind water. Semolina and coarse cereal fractions hydrate more slowly than fine flour and may require adjusted mixing, resting, scalding, or soaking.
A professional baker therefore asks not only “How much flour?” but “Which milling product, with what particle size, extraction, moisture, enzyme activity, and hydration behaviour?”
Water
Water is a functional raw material, not simply a carrier. It hydrates flour proteins and starch, dissolves salt and sugars, enables enzyme activity, supports yeast metabolism, determines dough consistency, and is one of the main controls of finished-dough temperature.
Hydration in baker's percentage expresses water weight relative to total flour weight. A formula containing 65 kg water for 100 kg total flour has 65% hydration. The same numerical hydration can still produce different dough consistencies because flours differ in absorption.
Key controls include potable-water quality, temperature, mineral composition where relevant, and dosing accuracy. In production, bakers often calculate water temperature from the target final dough temperature and the temperatures of flour, room, preferment, and mixing friction according to the bakery's method.
Water corrections should be recorded. Repeatedly adding “a little more water” without documenting the change makes process control and root-cause analysis difficult.
Biological Leavening and Fermentation Materials
Baker's Yeast
Commercial baker's yeast is based on selected strains of Saccharomyces cerevisiae. It ferments available sugars and produces carbon dioxide and flavour-active metabolites. The carbon dioxide expands gas cells that the dough structure must be able to retain.
Common commercial forms include compressed yeast, active dry yeast, and instant dry yeast. They are not always substituted gram-for-gram. Follow the supplier's conversion guidance and your formula standard. Yeast activity depends strongly on temperature, dough composition, fermentation time, osmotic pressure, and storage history.
In sweet enriched doughs, high dissolved-sugar concentration can create osmotic stress. Osmotolerant yeast is selected for better performance under these conditions. Increasing ordinary yeast without understanding the formula may create inconsistent fermentation or flavour.
Sourdough and Preferments
Sourdough is a fermented flour-and-water system containing yeasts and lactic acid bacteria. Its technological effects can include leavening, acidification, flavour development, modification of dough rheology, and improved keeping quality, depending on flour type and process.
A bakery controls sourdough through parameters such as inoculation, flour and water ratio, time, temperature, acidity, aroma, maturity, and refreshment schedule. A mature sourdough is not judged only by whether it “has bubbles”; it must meet the process target for the intended bread.
Preferments such as poolish, biga, sponge, and pâte fermentée differ in hydration, inoculation, salt content, and fermentation conditions. Their names and conventions vary by baking tradition, so a production formula should specify measurable parameters rather than relying only on a traditional name.
Chemical Leavening
Baking soda is sodium bicarbonate and requires enough acid in the formulation to generate carbon dioxide effectively and avoid an undesirable alkaline balance. Baking powder combines bicarbonate with one or more acid components and usually a carrier such as starch. Double-acting baking powders are formulated to release gas in more than one stage, commonly during mixing and again with heat.
In professional cake and biscuit production, chemical leaveners must be scaled precisely and distributed uniformly. Too little may give excessive density; too much can cause coarse structure, collapse, off-flavour, excessive spreading, or surface defects. Formula acidity, batter temperature, mixing, deposit weight, and oven profile must be considered together.
Salt, Sugar and Sweeteners
Salt
Salt provides flavour, but its technological role is broader. In wheat dough it can strengthen and tighten the gluten network and it moderates yeast fermentation. Incorrect salt dosing therefore changes both taste and process behaviour.
Because salt is used at relatively low percentages, a small weighing error can have a large sensory and fermentation effect. Dedicated, calibrated small scales and clear batch records are important professional controls.
Sugar and Other Sweeteners
Sugar contributes sweetness, bulk, colour development, tenderization, water-binding effects, and—in suitable dough systems—fermentable substrate. High sugar concentrations can reduce available water and slow ordinary yeast activity.
Honey, syrups, invert sugar, glucose syrups, malt products, and other sweeteners differ in water content, sugar composition, flavour, reducing-sugar content, viscosity, and browning behaviour. Substituting one for another can therefore change dough or batter consistency and baking colour even when the sweetness seems similar.
Professional formulas distinguish between the functional purpose of a sweetener and its sensory purpose. When a supplier changes a syrup concentration or a bakery changes from dry sugar to liquid sweetener, the water balance must be recalculated.
Fats and Oils
Fats contribute tenderness, lubrication, aeration potential, flavour release, crumb softness, mouthfeel, and shelf-life effects. The decisive property depends on the product.
In laminated dough, fat plasticity is critical. Roll-in fat should form continuous layers under the selected dough and room temperature without shattering, smearing into the dough, or melting out. Butter, margarine, shortening, and specialist roll-in fats differ in melting profile, water content, flavour, and working range.
In short doughs, fat coats flour particles and limits gluten development. In creamed cake systems, appropriately plastic fat can help incorporate and stabilize air during mixing. Liquid oils behave differently because they do not form the same crystalline fat structure.
Rancidity, oxidation, odour pickup, and temperature abuse reduce fat quality. Store fats according to specification and protect them from heat, light, oxygen, and cross-contamination as appropriate.
Eggs and Dairy Ingredients
Eggs and Egg Products
Egg ingredients contribute water, proteins, lipids, emulsifiers, colour, flavour, foaming capacity, and heat-set structure. Egg white proteins can form foams; yolk contains emulsifying phospholipids such as lecithin. Whole egg, yolk, albumen, pasteurized liquid egg, frozen egg, and dried egg products therefore cannot be treated as identical materials.
Professional controls include approved sourcing, required storage temperature, packaging integrity, lot traceability, hygiene, and prevention of cross-contact. Where pasteurized liquid egg is specified, replacing it with shell egg without authorization can alter both food-safety controls and formula water balance.
Milk, Cream, Buttermilk and Milk Powders
Dairy ingredients contribute water, lactose, milk proteins, minerals, and varying amounts of milk fat. These components influence flavour, crust colour, crumb tenderness, nutritional profile, and dough or batter solids.
-and-Milk-(left).jpg)
Milk powder and whey-based bakery ingredients add solids with much less water than liquid milk. Buttermilk provides acidity as well as dairy solids. A substitution therefore requires formula correction rather than a simple one-to-one weight exchange.
Cocoa, Chocolate, Nuts, Seeds, Fruit and Spices
Cocoa and Chocolate
Cocoa powder contributes flavour, colour, solids, fat, and strong water-binding effects. Natural and alkalized cocoa can differ in acidity, colour, and flavour. Adding cocoa to a cake or biscuit formula often requires an adjustment to flour solids, hydration, leavening balance, or all three.
Couverture chocolate contains cocoa butter as its characteristic fat phase and is designed for applications where flow, setting, gloss, and snap may matter. Compound coatings use alternative fat systems and are processed differently. Do not interchange them without considering fat compatibility, tempering requirements, flavour, and labelling.
Nuts and Seeds
Nuts and seeds contribute flavour, fat, texture, protein, and visual identity, but they can also alter dough hydration and processing. Roasting changes aroma and moisture; chopping changes surface area; and soaking or scalding can change water distribution.

For seeded bread, dry seeds can draw water from the dough during resting and baking. A controlled soaker or scald can improve hydration consistency, but the added water must be included in formula calculations.
Dried Fruit and Spices
Dried fruit adds sugars, acids, fibre, and concentrated flavour. Its moisture level affects dough consistency and shelf life. Some bakeries soak raisins or other fruit to standardize softness and reduce competition for dough water.
Spices such as cinnamon, cardamom, anise, caraway, and coriander are used at low dosages but have high sensory impact. Volatile aroma compounds are sensitive to age, grinding, heat, and storage. Accurate scaling and protected storage are therefore important.
Functional Ingredients, Improvers and Processing Aids
Modern bakeries may use malt products, enzymes, emulsifiers, ascorbic acid, vital wheat gluten, hydrocolloids, fibres, preservatives, release agents, or complete improver systems. Their legal status, declaration requirements, and permitted uses vary by jurisdiction and product.
An enzyme is a catalyst, so a small dosage can have a large process effect. For example, amylases act on starch-related substrates and can affect fermentable sugar supply, crust colour, crumb softness, and dough behaviour. Excessive enzyme activity can also create serious quality faults. Never “dose by eye.”
A premix may contain several functional ingredients already blended by a supplier. Before using it, you need the current specification, allergen information, dosage range, storage conditions, shelf life, and batch traceability. If a premix changes, the bakery should treat that as a formulation change even when the finished product name remains unchanged.
Baker's Percentage and Formula Control
Baker's percentage expresses every ingredient as a percentage of the total flour weight, which is defined as 100%. It allows you to compare formulas, scale batches, and see functional relationships.
For a simple bread formula:
- Total flour: 100.0 kg equals 100%.
- Water: 65.0 kg equals 65%.
- Salt: 2.0 kg equals 2%.
- Fresh yeast: 2.0 kg equals 2%.
The total dough mass is 169.0 kg. If production needs a different dough mass, scale all ingredients by the same factor. Preferments create an extra calculation step because the flour and water inside the preferment still belong to the formula totals.
In production records, write percentages and masses with appropriate precision. A 0.1 kg error may be trivial in 100 kg of flour but catastrophic for an enzyme concentrate or concentrated flavour. The acceptable tolerance depends on the ingredient and the bakery's control plan.
Ingredient Receiving, Storage and Quality Assurance
A raw material can be correct when it leaves the supplier and unsuitable by the time it reaches the mixer if receiving and storage are poorly controlled.
At goods-in, check the approved supplier and product name, packaging condition, lot code, date status, quantity, temperature where applicable, signs of moisture or pest activity, and any required certificate or specification. Quarantine or reject material according to procedure when acceptance criteria are not met.
Dry ingredients such as flour, sugar, salt, cocoa, and many seeds should be protected from humidity, pests, foreign odours, and contamination. Chilled ingredients such as certain egg or dairy products require a controlled cold chain. Fats and chocolate require storage conditions that protect their physical and sensory quality.
FEFO means first expired, first out: material with the earliest relevant expiry or best-before date is used first when appropriate. FIFO means first in, first out. Your bakery's written procedure determines which rule applies to each stock category.
Traceability links the supplier lot to internal batches and finished products. Do not discard lot information when decanting ingredients into bins; transfer the necessary identification according to the bakery's procedure.
Flour and Dry-Store Defect Checks
Typical warning signs include damaged sacks, insect activity, condensation, caking, unusual odour, colour change, foreign material, or a mismatch between delivery label and purchase specification. Sensory inspection can identify obvious defects, but it does not replace laboratory testing or microbiological controls where these are required.
Flour is a raw agricultural material and should not be treated as a ready-to-eat product. Avoid tasting raw dough or raw flour mixtures, maintain clean ingredient handling, and follow validated baking and hygiene procedures.
Allergen and Cross-Contact Management
Bakery raw materials commonly contain major food allergens. In European Union settings, the regulated list includes cereals containing gluten, eggs, milk, peanuts, soybeans, nuts, sesame, and other allergens relevant to particular bakery ingredients. Sulphur dioxide and sulphites can also be relevant, for example in some dried fruit, when regulatory thresholds are met. Other jurisdictions use different lists and rules, so always follow the legislation and company procedure that apply to your workplace.
Allergen control is not achieved by a label alone. It requires approved specifications, supplier-change control, identified storage locations, protected containers, dedicated or controlled utensils, planned production sequence, validated cleaning where necessary, rework control, label verification, and staff communication.
A useful principle is: identify the allergen at goods-in, control it through storage and production, and verify the correct declaration at dispatch.
Troubleshooting Raw-Material Effects
When a batch fails, avoid changing several variables at once. Compare the defect with retained records and ask what changed in raw material, formula, process, equipment, or environment.
| Production observation | Possible raw-material contribution | Professional check |
|---|---|---|
| Dough is unexpectedly stiff | Flour absorption increased or a high-water-binding ingredient changed | Compare flour lot, absorption data, hydration, bran or seed additions, and scaling records |
| Dough spreads during proofing | Flour strength, enzyme activity, salt level, or water balance may be unsuitable | Check specification, Falling Number where relevant, salt scaling, dough temperature, and formula |
| Fermentation is slow | Yeast activity, salt, sugar concentration, or dough temperature may be limiting | Check yeast storage and age, formula concentration, water temperature, and proof conditions |
| Sweet dough ferments poorly | Osmotic pressure may inhibit standard yeast | Check sugar percentage and whether osmotolerant yeast is specified |
| Rye crumb becomes gummy | Starch and enzyme balance, acidity, hydration, or bake may be inappropriate | Check rye flour specification, sourdough maturity, pH or acidity target, water, and bake profile |
| Cake has coarse tunnels | Leavener dosage or distribution may be excessive or uneven | Verify scale accuracy, premix distribution, batter mixing, and oven conditions |
| Croissant fat breaks into pieces | Roll-in fat may be too cold or insufficiently plastic | Check fat temperature, dough temperature, lamination schedule, and supplier working range |
| Seeded bread becomes dry | Seeds may be absorbing dough water | Compare seed moisture, soak procedure, soak water, and total hydration |
The table is a diagnostic starting point, not proof of cause. Confirm a hypothesis by checking records and, where practical, running a controlled trial.
Sustainability and Purchasing
Sustainable raw-material purchasing requires more than choosing the closest supplier. A bakery can consider agricultural practices, verified certification, transport, packaging, storage losses, yield, ingredient functionality, food waste, supplier reliability, and product quality together.
A cheaper flour that causes greater dough loss, rejects, or inconsistent volume may have a higher real production cost. Likewise, purchasing very large packs may reduce packaging per kilogram but increase waste if stock exceeds shelf life. Professional purchasing therefore connects technical specification, total cost, quality consistency, and resource efficiency.
