An Engineering Model for Pulse Protein Wet Extraction and Isolation

Description: There is a growing consumer demand for natural, plant proteins and in particular, pulses are becoming a premier protein source for formulation into foods and beverages. Consequently, there is a significant need for the development of efficient commercial scale manufacturing processes for high purity pulse protein isolates, starch and fibre ingredients. The processing involves wet (i.e. aqueous) extraction, purification and drying to produce the powdered ingredients. The economics of processing are significantly dependent on the selection of processing techniques, equipment, and final product quality attributes. An effective process protocol with high yield, high purity and efficiency is paramount for a successful commercial processing line. Both ultrafiltration and isoelectric precipitation processes may be used for purification of protein isolates however the economic feasibility may differ with the pulse, process flow and equipment selection. In order to design an efficient process protocol for a protein isolate, process modeling was applied to predict mass, energy, water and yield of the various ingredient co-products. Each process was simulated using SuperPro Designer modeling software. This analysis also included Capital Expenses (CAPEX) and Operating Expenses (OPEX) estimates, feed and product costs, Hazard and Operability Study (HAZOP) and Hazard Analysis Critical Control Points (HACCP).
