Wet/PDG starch is a type of starch which has been modified such that it can dissolve or dispense in cold water without being heated to create pastes and gels. It has cold solubility, thickening, binding, film forming properties that render it a useful ingredient in food, pharmaceutical, paper, textile, adhesives, cosmetic, as well as the construction industry.
To entrepreneurs, the development of PDG starch comes as a prospective opportunity to add value to the current processing capacity and ready usable native starch (corn, tapioca, potato, cassava) to achieve a potential end use in several markets. This will result in a sustained global demand of PDG starch that provides producers with capacity to operate at least in some of viable end markets and hence cuts/lessens dependence on one market to provide capacity to sustainably operate in the market. The forces behind increasing demand and value of PDG starch remain related to convenience in food consumption or prepared food consumption, continuing demand and reliability in melted or modified starch as a pharmaceutical excipient, and consistency related with use in industry, when a required adhesion or binding is needed e.g. paper, adhesives.
Asia Pacific region is experiencing an expansion of the need to meet growing demand of food processing and industrial consumption and is rating as an example of the demand compared to the mature markets of Europe or North America which tend to be larger, stable and hence more mature. These circumstances offer both giving chances of marketable surplus of PDG or industry grade or greater specialty or increased value grade of PDG- or modified starch materials.
Important Applications and Target Customers.
PDG starch is mostly employed in the practice when an instant viscosity or cold solubility is required.
- Food producers who are in need of instant soups, sauces and bakery stabilizers.
- The manufacturers of nutraceuticals concentrated on the application of PGS in tablet binding or disintegration.
- Manufacturers of paper, textile and adhesives industries requiring a sizing, coating or bonding agent.
Launch sales process on one or two specific focus areas, on which you will be able to offer sample performance and technical support.

Positioning and Grades of products.
Start with narrow range of product grades to control process complexity to shorten time to market:
- Reduce product grade variety to simplify process to reduce time to market:
- Pharma grade PGS is used in those applications where there is established purity and it is required to be attributed to a batch.
- PGS in industrial grade is meant to be used on paper, textiles and adhesives.
When pilot and customer verification has been achieved, come up with specialty variations (such as freeze-thaw stable or high-clarity grades).
Production process – short description.
Its manufacturing principle is simple, to make a slurry of starch, gelatinize, dry the cooked material into flakes, and mill it into a cold-soluble powder. Widely used industrial processes include drum drying, roller drying and extrusion cooking. Key process steps:
Raw material checks
Test moisture, granule quality, microbial load, and no foreign matter in native starch feedstock. Work out supplier requirements and insist on certificates of analysis.
Preparation and cooking of slurry.
Formulate an isolated starch-water slurry and gel under special heat and shear circumstances suitable to the source of starch and capability sought.
Drying and pregelatinization.
Drum/roller dryers/ extrusion may be used to convert the cooked slurry into dry flakes, and it is then dried. The drying process influences the morphology, solubility kinetics and bulk density of the particle – matters of interest to the end users.
Milling and classification
Dry flakes to desired particle size and filter oversized material in order to maintain rehydrating properties.
Elective mixing and practical adjustment.
Additives Add approved additives or mix grades to adjust viscosity, clarity, freeze-thaw stability or storage characteristics to match your target market, but only additives allowed in your target market.
Packaging and storage
Apply moisture barrier packaging with distinct labels of batches. In the case of regulated customers, ensure that there is traceable storage and handling processes.
Layout (high level) Equipment.
Much-needed equipment consists of slurry tanks with heating and agitation, drying system (drum/roller dryer or extruder plus dryer), mills and classifiers, dust extraction, and packing lines. Draw a flow from raw starch to finished product in one direction to minimize the risk of contamination and to have efficient operations. Provide proper dust management and safety measures.
Quality management and conformity.
Critically test parameters like moisture, solubility, viscosity, particle size, ash content and microbiological safety. Keep certificates of analysis and batch traceability; particularly among the food and pharmaceutical customers. Investment in QC and documentation at an early stage results in less friction in the market-entry and generates confidence of buyers.
Environmental, safety and operating notes.
The primary energy consumer is a drying type, so drying should take into account heat recovery or energy-saving drying. Proper treatment of process water and slurries. Control the risks of dust and explosions through extraction and grounding and proper PPE. Hygiene, safety and process control training to train staff.
Go-to-market strategy and market positioning.
Produce application data and give sample packs to potential customers. Select a positioning strategy in the market:
- Contend with regular supply of commodities at stable specifications and prices.
- Niche, segmenting, of higher-margin segments (pharma-grade, clean-label, or specialty functional grades) with documentation and formulation support.
Collaborating with ingredient suppliers, co-packers or OEMs can speed up market penetration.

Risks and mitigations
- Feedstock variability: secure contracts, define strict supplier specs, and perform incoming checks.
- Process sensitivity: pilot your chosen drying method to confirm functionality before scaling.
- Dust and safety hazards: install extraction systems, explosion mitigation, and follow regulations.
- Regulatory challenges: prepare compliance dossiers early for food and pharma customers.

Scaling and innovation opportunities
After validating a pilot, scale by introducing tailored functional grades, pursuing clean-label physical modification routes, sourcing premium or traceable starches, and improving energy efficiency through heat recovery or extrusion-based continuous processing.
Practical startup checklist
- Determine target customer segments and product grades.
- Secure native starch supply and define incoming specifications.
- Pilot the drying method (drum, roller, or extrusion) and validate functionality in real formulations.
- Establish basic QC testing and traceability systems.
- Prepare packaging, storage solutions, and regulatory documentation for your target markets.
