Study Notes
Cereal Technology: Grains
- Grains, or cereals, are the edible seeds of grasses in the Poaceae family.
- Major global grains include wheat, corn (maize), oats, and rice.
- Less common grains include rye, barley, triticale, millet, and sorghum.
- Cereals are a significant part of the global food supply.
- They provide more energy than other crops, hence their classification as staple crops.
- Pseudocereals, like quinoa and buckwheat, are not true cereals but are used similarly.
Cereal Grain Composition
- Endosperm: The largest part, primarily carbohydrates (starch) and protein (including gluten).
- Germ: The embryo, rich in nutrients (vitamins, minerals, healthy fats, and protein).
- Bran: The protective outer layer, high in fiber and some vitamins and minerals.
- Aleurone Layer: Located between bran and endosperm, rich in protein and nutrients.
Wheat: A Detailed Look
- A major global staple, crucial for nutrition, economies, and cultures.
- Major source of carbohydrates for energy, dietary fiber, protein (especially gluten), vitamins (B vitamins), and minerals (iron, zinc, magnesium).
- Economically important for global trade and supports livelihoods.
Wheat Growth Cycle
- Germination: Seed absorbs water, radicle emerges.
- Seedling Growth: True leaves emerge, photosynthesis begins.
- Tillering: Additional shoots (tillers) grow, potentially producing grains.
- Stem Elongation (Jointing): Stem lengthens.
- Booting: The wheat head fully develops but is still enclosed.
- Heading and Flowering: The head emerges and the plant pollinates; wheat is self-pollinating.
- Grain Filling: Kernels grow and fill with starch, needing adequate water and nutrients.
- Maturation (Ripening): Grain hardens and turns color.
- Harvest: Grain is cut, separated from chaff, and cleaned.
Wheat Grain Components
- Bran: Tough outer layer, protecting inner parts; rich in fiber, iron, magnesium, and B vitamins.
- Endosperm: Largest component, majority starch and gluten, providing energy.
- Germ: Embryo capable of growing a new plant, containing many nutrients.
- Aleurone Layer: Between bran and endosperm; rich in protein and enzymes.
Einkorn Wheat: Ancient Variety
- One of the earliest cultivated wheats.
- Diploid (two sets of chromosomes).
- Has a single grain per spikelet.
- Considered more nutritious than modern wheat varieties, with higher protein, essential fatty acids, and specific vitamins and minerals.
Modern Wheat Types
- Classified by endosperm texture (hard or soft) and kernel color (red or white).
- Hard Red Winter (HRW), Hard Red Spring (HRS), Soft Red Winter (SRW), Hard White (HW), Soft White (SW), Durum Wheat.
- Durum is used for pasta.
- Attributes like endosperm texture and seed color affect baking and flour characteristics.
Wheat Milling
- Cleaning: Removing impurities.
- Conditioning (Tempering): Moistening to soften bran and mellow endosperm, aiding the milling process.
- Breaking and Grinding: Reducing grain size.
- Purification: Separating flour from bran and germ using sieves and air currents.
- Reduction: Further reduction of endosperm size (increasing fineness).
- Grading: Classification of flour based on particle size (e.g., semolina, flour).
- Implications of milling include nutritional value reduction in refined flour and impact on shelf life and texture.
Baking
- Baked products: Bread, cakes, pastries, cookies, crackers, pizzas, and others.
- Ingredients: Flour, water, yeast/chemical leavening, salt, and optional additions like sweeteners, fats, flavorings.
- Key roles of essential ingredients: Flour (structure), water (activates gluten), yeast/chemical leavening (fermentation, rising), salt (flavor, controls yeast).
- Gluten: Proteins (gliadin and glutenin) in wheat endosperm, providing dough elasticity and gas retention.
- Breadmaking methods include straight dough method, sponge-and-dough, no-time method, sourdough, continuous mixing, delayed salt method.
Leavening Agents
- Biological: Yeast – fermentation and creates carbon dioxide, giving a characteristic flavor.
- Chemical: Baking soda (needs acid), baking powder (acid + base), ammonium bicarbonate (older, can impart an ammonia odor if not cooked thoroughly).
- Physical: Steam (high moisture), air (beating).
Quality Control in Flour and Bread
- Flour: Testing physical properties (color, particle size), chemical properties (protein content, moisture, ash), functional properties (water absorption, gluten quality, enzyme activity), and microbiological aspects.
- Bread: Testing physical properties (volume, crumb grain, crust color), texture (firmness, chewiness), chemical properties (moisture, pH), and sensory aspects (flavor, odor, appearance).
- Tools for assessing flour quality: Farinograph, extensograph, alveograph.
