TSP Production: ExPress® Soy vs. Hi-Pro (Solvent) Meal

A common question that arises when a company analyzes making texturized soy protein (TSP) is whether to make it from expeller or Hi-Pro (Solvent meal).


Below is a breakdown of the main comparisons between the production of ExPress® vs Hi-Pro for making TSP:


TSP ExPress®

TSP Hi-Pro
Capacity 500-750 lbs/hr 300-350 lbs/hr
Absorption Rate 3.2 to 4 times its weight in water 2.8 to 3.2 times its weight in water
Additives Not Needed (around 50 PDI) Normally Needed (low PDI, around 25)
Extruder Options MS3000 Medium Shear Model (meat extender and chicken imitation pieces)

2000 High Shear Model (meat extender)

Only 2000 high shear model (meat extender)
Market Limitations None Some markets less willing to purchase TSP made with hexane and additives
Ease of Use Option of MS3000 is a more automated process 2000 with solvent meal may require extra cutter head on extruder barrel (if PDI is too low)
Boiler (gas connection) Needed (Used for preconditioner) Can use a mixer which does not require steam
Products Preconditioner is located on top of the extruder, reducing footprint Only meat extender (no shapes)
Footprint Preconditioner is located on top of the extruder, reducing footprint Mixer generally located in its own area, requiring more space
Control Panel Touch Screen Analog
TSP Color Light to medium color Tends to be lighter in color


The ExPress® extrusion line with medium shear extrusion as it has the added benefits:

  • Control of the whole quality chain process (from bean to TSP, controlling your meal)
  • Insta-Pro extruders offer almost double the production capacity when using ExPress® instead of Hi-Pro as an ingredient
  • Absorption rate much higher between 3.2 to 4 instead of 2.8 to 3.2
  • Gives the option to use the MS3000 medium shear to make both type of TSP: extender & replacement.
