The main
components of
flour and bread
additives
are enzymes.
![Page 6: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/6.jpg)
The ingredients for flour improving are
especially ultra concentrated enzymes
catalyze chemical reactions in the
case of flour/dough.
3. Stabilization And Improving The Quality Of Flour
With Enzymes
Ultra concentrated
enzymes
• Low dosages(ppm)
• Yield big desired effects
![Page 7: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1.

4. Enzymes Versus Flour Rheology
One quick and economical way to
determine the effects of enzymes is
using flour rheology test equipments
which are
Farinograph
Alveograph
Mixolab
Falling Number
![Page 9: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/9.jpg)
AMYLASE
Amylase have measurable effects on the Rheofermentometer with improved gas production and dough height.Amylase has an effect on Falling NumberIncreases L value on alveograph
XYLANASE Xylanases might have positive effects on Alveograph P/L ratio increasing L.
LIPASEPHOSPHOLIPASE
Lipase and phospholipase, normally would not have measurable rheological effects.
OXIDASEGlucose Oxidase improves the Farinograph stability and reduces the Farinograph degreeof softening.
PROTEASEProteases have a strong, measurable effect on the Alveograph; the addition of a protease strongly reduces W values leaving P/L ratio almost unchanged

7. MIRPAIN’S TAILOR MADE ENZYMATIC FLAT
BREAD SOLUTIONS
Most common problems of flat bread:
•Springing back or shrinkage of the dough
•Falling off the wall of the oven during baking
•Drying too quickly, not enough browning
•Poor dough stability
•Poor sheeting quality
•Breaking of the loaves during shelf-life
![Page 28: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/28.jpg)

8. When are enzymes used in pasta production?
Nowadays pasta is made from unconventional commodities in
many countries of the World due to the high price of durum
wheat.
Sufficient processing and balanced formulations are required to
eliminate unconventional commodities poor technological
properties.
![Page 30: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/30.jpg)
• Economically speaking, the use of soft wheat flour for
pasta production could be advantageous; however,
the poor sensory attributes and cooking quality of
such products have dictated that durum semolina be
used.
• Attempts to overcome the poor quality of non-
conventional pasta have primarily relied on the use of
additives.
• It has been reported that firmness, color intensity and
cooking quality have been improved with the
appropriate drying program and additives.
![Page 31: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/31.jpg)
Pasta Quality Parameters
• Stickiness
• Firmness
• Elasticity
• Brightness
• Cooking tolerance
• Biting quality
• Color
![Page 32: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1.

Texture Analysis for Pasta1.Flexibility
Probe: Spaghetti Flexure Rig
Spaghetti flexure rig determines the elasticity of the
spaghetti by measuring the breaking distance of the
samples.
![Page 33: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/33.jpg)
2. Stickiness
Probe: Spaghetti Stickiness Rig
This equipment measures the durability and
stickiness of the cooked pasta. The pasta
cooked under the same conditions according to
the method is kept in the texture analyzer using
a support block.
![Page 34: FUNCTIONS OF THE ENZYMES ON FLOUR QUALITY...Wheat flour quality + Additives. 1. Factors Effects on Flour Quality Individual genetic disposition of wheat cultivar Agricultural practices](https://reader031.vdocuments.us/reader031/viewer/2022013003/61086979fff77047163ffb93/html5/thumbnails/34.jpg)
• The pressure plate attached to the load
cell immobilizes the pasta.
• The probe applies an appropriate
compression force to the sample.
• It contacts the sample for a certain
period of time, and as the force required
to remove the probe from the surface of
the sample increases, the pasta is more
sticky.

3.Firmness
Probe: Pasta Firmness-Quality Rig / Light Knife Blade
Pasta Firmness-Quality Rig measures the firmness / hardness of the cooked pasta.

• The probe draws graphs and measures
according to the force applied when
cutting the cooked spaghetti on the flat
platform.
• The increasing in the firmness of the
pasta increases the cooking tolerance
and biting quality.
