Advantages Extruded Snacks Extrusion of whole yellow pea flours is more controlled than for the split yellow pea flours. Additional fibre of whole yellow pea flours acts as a nucleation agent and controls air cell size of extrudates. Challenges Direct expanded products made with whole yellow pea flour are darker in colour and have a greater bulk density than split yellow pea flour. Coating with complementary flavours Small reference amount, difficult to make protein claim Solutions Bending with other ingredients to improve nutrition, taste and texture
Pasta Pulse flour milling to produce low medium and high protein content flour Blended with durum semolina 30:70
Pasta
Pasta Esey Assefaw Head Asian Products and Pasta Department Canadian International Grains Institute eassefaw@cigi.ca
Advantages Pasta Increase protein content, quality and nutrient density No change in cooking time Challenges Dough crumb sticky, effects extrusion Darkening of pasta with HTST drying Drying cycle effects pasta cooked firmness Soluble proteins leached in cooking water Solutions 2% reduction in water addition for yellow pea semolina Use LTLT drying profile to minimize colour changes Use fine semolina pulse ingredient and the LTLT drying profile for best appearance and cooked pasta firmness
Noodles
Sandwich sheeting for whole wheat noodles (Cigi Asian Products Department) Processing method to improve end product quality standard processing method - 2 dough sheets are formed at first pass then 2 dough sheets are laminated to form 1 dough sheet on second pass sandwich sheeting processing method - 3 dough sheets are formed at first sheet forming pass then 3 dough sheets are laminated to form 1 dough sheet. Esey Assefaw Head Asian Products and Pasta Department Canadian International Grains Institute eassefaw@cigi.ca
Hoppers (where the noodle crumbs go to) Three rolls in the first pass (sheet formation) Rolls in the second pass (sheet lamination/compounding)

Gluten-Free Pan Bread
Gluten-Free Pan Bread
Gluten-free Pan Bread Improved nutritional profile of the bread eligible for a dietary fibre nutrient content claim. The addition of pulse flours resulted in breads with a firmer texture and smaller cell diameters compared to the control bread Among the three pulse types, the bread containing fava bean flour produced a bread with milder flavor
Whole Wheat Pan Bread Quality Whole-wheat breads formulated with 15% whole yellow pea flours. Pea flours were milled using four methods ( L to R: Pin Mill Fine, Stone Mill, Hammer Mill, Roller Mill)

Gluten-free Crackers Pulse flours and pea fibre crackers were more firm and generally thicker compared to the control cracker Yellow pea/pre-cooked navy bean best maintained its texture and produced the thinnest cracker Crackers made with the yellow pea/red lentil flour produced a cracker with the most desirable flavour Pulse flour improved nutritional profile of glutenfree cracker Source of fibre claim
