Among plant-protein ingredients, pulse flour and pulse protein concentrates are widely regarded as among the most cost-effective. Pulses are commodity-scale crops with established Canadian production, which keeps raw-material pricing competitive. For ingredient buyers prioritizing both sustainability and cost, pulse flour — particularly lentil, chickpea, and fava bean flour — is a practical starting point. SSI mills four pulse flours in Saskatchewan and supplies them in 1 MT totes and 25-kg bags, shipped by container or intermodal.
