High-Moisture Protein Fibration of Pulse Ingredients
Pulses Grown in Canada
Pulse Ingredients
• Whole and split seeds
• Whole and split flours
– Functionality varies based on milling method
• Pre-treatments
– Tempering, roasting, sprouting, hydrothermal
processing
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Ingredients
• Pea hull fibre
– >80% total dietary fibre (mostly insoluble)
• Cell wall fibre
– Blend of fibre and starch
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Ingredients
• Concentrates
– Starch concentrates: typically 78-85% starch
– Protein concentrates: typically 45-65% protein
• Isolates
– Starch isolates: >95% starch
– Protein isolates: > 80% protein
High-Moisture Protein Fibration of Pulse Ingredients
Why High-Moisture Protein
• Vegetarian/Vegan/Flexitarian
– Looking for more variety
• More product launches in meat alternatives
– Fresh, refrigerated and frozen
High-Moisture Protein Fibration of Pulse Ingredients
Why High-Moisture Protein
• More research and more products

Formats
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Protein Experiment 1
High-Moisture Protein Fibration of Pulse Ingredients
• Formulation:
• Test proteins included:
– Soy protein concentrate (74% protein)
– 5 Pea protein isolates (>80% protein)
– 1 Chickpea protein isolate (>80% protein)
Ingredient %
Wheat gluten 48
Test protein 42
Starch 3
Fiber 3
Sugar 4
Pulse Protein Experiment 1
• Certain pea protein isolates perform better than others
• Operate extruder at lower temperatures when extruding pea protein isolates than the soy protein concentrate (5-10°C lower)
• Total moisture of extruding mass was 1-2% lower than the standard formulation containing soy protein concentrate
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Protein Experiment 1
• Able to achieve a variety of textures with pea
protein isolates
• Chickpea protein isolate did not perform well in
this trial

Pulse Protein Experiment 2
• Formulation:
• Test proteins included:
– Soy protein concentrate (74% protein)
– 5 Pea protein isolates (>80% protein)
High-Moisture Protein Fibration of Pulse Ingredients
Ingredient %
Test protein 90
Starch 3
Fiber 3
Sugar 4
Pulse Protein Experiment 2
• Range of textures able to produce is limited
• Operate extruder at lower temperatures when extruding pea protein isolates than the soy protein concentrate (10-15°C lower)
• Total moisture of extruding mass was 1-2% lower than the standard formulation containing soy protein concentrate – 4-5% lower moisture than the formulations from
Experiment 1 containing gluten
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Starch/Fiber Experiments
• Starch in formulation can be:
– Dry fractionated starch concentrates: pea, faba bean
or lentil
• Fibre in the formulation can be:
– Fibre from the seed coat of pea
High-Moisture Protein Fibration of Pulse Ingredients
Pulse Concentrates Experiment
• Products of dry fractionation
– Pea, faba bean and lentil
• Contain too much starch
• Final extrudate is too gummy
• Highest inclusion rate is 20%
– Lower for pea protein concentrate due to flavour
High-Moisture Protein Fibration of Pulse Ingredients
Other notes
• Hydrolyzed proteins help with flavour
• Gums help with water retention
– Protein-gum blend is matched and inclusion rate of
gum varies

Kill-Step Validation Study
• Objective:
– Determine if the combination of temperature,
pressure and shear could reduce pathogens by 5 log
in high-moisture extrusion
• Preliminary Trials
– No pathogens found in flour
– All trials reduced standard plate count from 100,000
cfu/g to at maximum 20 cfu/g (most were none
detected)
