Variations of Wheat Quality
Additives• Vitamins- enrichment
• Malted barley- amylase
• Fungal amylase
• Potassium bromide- oxidizer
• Benzoyl peroxide- bleach
• Azodicarbonamide- Bleach- acts as maturing agent
Analytical specifications
• Moisture- Max 14%
• Ash/Extraction rate/Mineral content
• Protein content- %
• Enzyme activity- Falling number>250-350
• Mixability- Farinograph
• Elasticity/Extensibility- Alveograph
QC of Wheat FlourTypical characteristics of wheat flour that fluctuate, and the test available to check the quality.
Flour Characteristics
• Protein (Amount, quality)
• Elasticity (P), extensibility (L), Strength (W) P/L =.6 (Alveograph)
• Mixing properties (Farinograph)
• Absorption capacity, Development time, Stability ( high protein vs. low) Mixing tolerance index ( high is weaker)
Spec sheet
• States type(s) of wheat
• Will contain Moisture, Protein and Ash %
• May have falling number
• Can request falling # and Farinograph analysis from miller
Spec Sheet
Flat Breads
• Can be leavened or unleavened
• Can be baked over open fire or in pan- no oven needed
• Baked at high temperature- 500
• Used as utensil
Types of Flatbreads
• Naan- Afghanistan/Middle East- made with yogurt
• Lavash- Armenia/Middle East- Flavored with honey- baked on sides of Tandoori oven
• Pita- Greek/Mediterranean- Pocket bread
• Tortilla- Mexican- Unleavened- Made from corn or wheat- Cooked on hot metal plate or rocks
Tandoori oven
Conchas
• Mexican sweet bread
• Crumb topping on top ( 20g/ 85g roll)
• Can be colored topping
• Topping is Scored
• Simulates shell shape
• Conchas- 85g rounds- 6 per person
• DDT= 80, Intensive mix
Today’s Production
• As per Production Schedule
