# Food biopolymers (starches, polysaccharides, plant proteins) B2B food-grade biopolymers — modified starches, plant-protein isolates and hydrocolloids — produced by reactive extrusion, wet fractionation and isopropanol precipitation for texture, structure and clean-label formulation across the food industry. Source: https://en.bioecon.ru/technology/food-biopolymers-starches-polysaccharides/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: FDA Food Contact Substance & EFSA Novel Food (EC) 2015/2283 | OECD: Food systems | Regulator: FDA (USA), EFSA (EU), NMPA (China)] 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. ### Sectoral value chain ``` [starch crop / pea / microbe] ──> [fractionation] ──> [extrusion / precipitation] ──> [spray dry] │ (>85% protein / cross-linked starch) │ ▼ [B2B food SKU] <─── [texture profile] <─────┘ ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Raw Biomass** | starch crops, peas, soy, microbes, seaweed | **In:** crop, inoculum. **Out:** milled flour. | | **Fractionation** | wet pea/soy separation, starch refining | **In:** flour, water. **Out:** protein/starch streams. | | **Extrusion / Fermentation** | reactive extrusion or microbial xanthan | **In:** starch / broth. **Out:** modified starch / gum. | | **Precipitation + Dry** | IPA polysaccharide precipitation, spray dry | **In:** broth, IPA. **Out:** hydrocolloid powder. | | **Texture Profiling** | haptometric and rheology QC | **In:** powders. **Out:** functional ingredient. | | **B2B Food SKU** | clean-label, E-number, Kosher/Halal packaging | **In:** ingredient, packaging. **Out:** food-maker SKU. | Cross-cutting technologies of the sector: -

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. --- ## Value chains and production pipelines ### Industrial pipeline of a pea-protein isolate + modified starch lot (FDA / EFSA / FSSC 22000) ``` ┌───────────────────────────┐ ┌───────────────────────────┐ │ 1.
