Quality Testing - Solvent Retention Capacity

Elaine SopiwnykHead, Analytical Services

• Principle of the test:• Weight of solvent held by a flour after centrifugation and expressed as a percentage of flour weight (14% moisture basis)

• Typically performed on soft wheat flour• Predicts cookie baking performance

Solvent Retention Capacity (SRC)

Flour component Water absorption(relative to native starch)

Gluten 1.7 x

Pentosans 10 x

StarchNative, undamagedDamaged

1 x2 x

Flour Components & Water Absorption

These components not only affect water absorption but have structural implications

• Solvents: • Lactic acid, 5%: glutenin characteristics• Sodium carbonate, 5%: damaged starch• Sucrose, 50%: pentosans• Water: all quality parameters

• SRC results establish a flour’s quality profile

Solvent Retention Capacity (SRC)

SRC - Calculation

• % SRC = gel weight86

flour weight 100 – flour mc

SRC Results – Optimum Performance

AACC 56-11.02

Conformance of bakery production is improved when results are stable.

• Whole meal testing• Advantage: milling not required• Disadvantage: slight loss of accuracy but still useful for screening

• Small scale testing• Advantage: screening of early generations• Disadvantage: slight loss of accuracy but still useful for screening

**P < 0.05NS – not significant

• Relatively quick test that can be used for monitoring samples for cookie quality.

• Can be conducted using ground wheat.• Not all solvents need to be evaluated.
