1 · What it gives

Food biopolymers are the B2B ingredient spine of texture, structure and shelf-life across the food industry: modified starches from reactive extrusion, plant-protein isolates from wet fractionation, and hydrocolloids (pectin, gellan, xanthan, carrageenan, alginate) from microbial fermentation or seaweed extraction. A pea-protein isolate line recovers over 85% of the input protein via disc-centrifuge clarification and spray drying; modified starch lines run reactive extrusion that chemically cross-links amylopectin in a single continuous pass; and fermentation-derived xanthan reaches 250 m3 bioreactors with viscosity- controlled broth harvesting.

Key directions of food biopolymers:

  1. Modified starches (Modified Starches): reactive extrusion cross-linking and stabilising amylopectin for freeze-thaw and acid tolerance.
  2. Plant-protein isolates (Plant Proteins): pea (NUTRALYS), soy and pulse isolates at over 85% protein via wet fractionation.
  3. Hydrocolloids / polysaccharides (Hydrocolloids): pectin, gellan, xanthan, carrageenan and alginate for gelling, thickening and encapsulation.
  4. Functional protein systems (Protein Systems): high-moisture extrusion (HMEC) texturing plant proteins into fibrous meat analogues.

3 · How to implement 6 steps

  1. 1
    Crop milling
    Peas (or maize for starch) are cleaned, dehulled and dry-milled to a flour of controlled particle size, with protein and starch streams segregated for downstream fractionation.
  2. 2
    Wet fractionation
    The flour is suspended in water and separated in multi-stage disc centrifuges: the dense starch stream is drawn off for reactive extrusion, while the lighter protein stream is clarified and concentrated to over 85% purity on the protein line.
  3. 3
    Spray dry / precipitatePurification & downstreamField application & services
    The protein stream is spray-dried under controlled inlet temperature to preserve functional solubility; in parallel, any microbial polysaccharide stream is precipitated in isopropanol and vacuum-dried for hydrocolloid powder.

7 · Tech stack & innovations

The stack is built on thermal-mechanical starch modification, wet protein fractionation and microbial polysaccharide fermentation.

  1. Reactive extrusion (Reactive Extrusion):
    • twin-screw extruder plasticises native starch while cross-linking agents (STMP) and stabilisers are dosed in continuously.
    • single-pass output is a freeze-thaw-stable, acid-tolerant modified starch with tailored texture profile.
  2. Wet fractionation (Wet Fractionation):
    • pea flour is separated by disc centrifuge into protein, starch and fibre streams; protein is spray-dried to over 85% isolate.
    • SAP PLM controls the recipe; multi-stage spray dryers protect the protein’s functional solubility.
  3. Isopropanol precipitation (IPA Precipitation):
    • microbial xanthan/gellan broth is precipitated in isopropanol, vacuum-dried and milled to food-grade powder.
    • Emerson DeltaV automation controls the precipitation; Kosher/Halal certification covers the food chain.
