DOUGH

dough

is a viscoelastic system formed by

combining flour, water, and other

ingredients. Its behavior depends on

gluten development, fermentation, and

mixing techniques, which directly affect

texture, nutritional quality, and

digestibility of baked products

heterogeneous mixtures

Dough systems are ___ where proteins (gluten), starch,

fat, and water interact dynamically during

processing.

kneading

Scientific Basis

● Gluten forms from gliadin + glutenin

proteins

● Kneading aligns proteins into a

viscoelastic network

● This network allows: gas retention, dough

elasticity and extensibility

10-30 mins

duration of hand kneading

8-12 mins

duration of mechanical kneading

under-kneading

Dense, low volume,

wear structure

over-kneading

Tough, overly elastic

dough

Dry, hard bread

Excess flour during

kneading

fermentation

The biochemical

process where yeast converts sugars into

CO2 and ethanol.

Indicators of Good Quality

• High loaf volume

● Fine, uniform crumb

● Golden-brown crust

● Soft but elastic texture

Determinants

● Flour quality (protein content)

● Gluten strength

● Fermentation efficiency

● Proper baking conditions

dense loaf

Poor kneading or weak gluten - Low volume

overproofing

excess fermentation - collapsed structure

underproofing

insufficient fermentation - tight crumb

pale crust

low sugar or temperature - poor color

tough crust

overbaking - hard texture

rolled biscuits

drop biscuits

scones

kinds of biscuits (quick breads)

● Short crust (pies, tarts)

● Flaky pastry

● Puff pastry (laminated)

● Choux pastry

pastry types

choux pastry

Cooked, egg-rich dough; creates

hollow, airy shells (éclairs,

profiteroles)

puff pastry

Laminated dough; butter folded into

dough hundreds of times; light, flaky

layers (croissants, turnovers)

Biscuit Method

Fat is cut into flour before liquid is added

● Produces flaky texture

Muffin Method

Mix dry + wet separately, then combine

briefly

● Prevents gluten overdevelopment

Creaming Method

Fat + sugar creamed first

yeast breads

B vitamins (from yeast),

carbohydrates for energy

whole grains dough

high fiber, micronutrients

pastries

high in fat and energy densi
