If you are comparing curdlan gum prices in 2026, you may find quotations ranging from relatively inexpensive bulk food-grade material to laboratory-grade curdlan costing hundreds of dollars for only a few grams. Curdlan gum prices depend heavily on product specifications, gel strength, nitrogen level, curdlan content, order quantity, packaging, and delivery terms.
For B2B buyers, there is therefore no single price that applies to every curdlan product. A standard food-grade curdlan for general food processing can cost substantially less than a customized low-nitrogen, high-gel-strength grade designed for demanding applications.
As a bulk curdlan gum manufacturer and supplier in China, BSH Ingredients currently offers standard food-grade curdlan from approximately RMB 45/kg as a reference bulk price. This is not a fixed quotation for every specification. Buyers requiring higher gel strength, lower nitrogen levels, special quality parameters, custom packaging, or different order quantities should contact BSH Ingredients for an exact quotation.
What Is the Curdlan Gum Price in 2026?
The price of curdlan depends first on what kind of curdlan you are buying and in what quantity.
Research laboratories buying several grams, a food company purchasing 25 kg, and an ingredient distributor purchasing several metric tons are purchasing the same general ingredient category under completely different commercial conditions.
Laboratory and Small-Quantity Curdlan Prices
Laboratory-grade curdlan can be extremely expensive compared with industrial food-grade curdlan.
For example, Sigma-Aldrich currently lists Curdlan from Alcaligenes faecalis, ≥98% (TLC) at US$457 for a 5 g package. This is a laboratory/research product and should not be used as a benchmark for commercial food-grade curdlan purchased by the bag, pallet, or metric ton.
Online B2B marketplaces show a much lower range for industrial curdlan. For example, current Made-in-China listings advertise some food-grade curdlan products at approximately US$9-15/kg with a 100 kg minimum order. However, such advertised prices often do not provide enough information about gel strength, nitrogen level, curdlan assay, quality grade, taxes, packaging, or final shipping terms to make a direct technical comparison.
For serious commercial sourcing, buyers should therefore compare specification and price together, rather than simply choosing the lowest number shown online.
China Wholesale Curdlan Gum Price
For standard food-grade curdlan sold in China, recent factory quotations for basic specifications are commonly around RMB 55/kg or higher, depending on the supplier, specification, volume, and commercial conditions.
BSH Ingredients can currently offer a reference bulk curdlan gum price starting from approximately RMB 45/kg for standard product requirements.
However, this should be understood as a reference price rather than a universal BSH curdlan price.
The final quotation may be higher when a customer requires:
- Higher gel strength
- Lower total nitrogen
- Higher or customized curdlan content
- Tighter physicochemical limits
- Smaller purchase quantities
- Special packaging
- Private-label or OEM services
- Special export documentation
- Different Incoterms or delivery destinations
For this reason, buyers looking for the latest wholesale curdlan gum price per kg should provide their target specification and purchasing quantity when requesting a quotation.
What Specification Does the Reference Curdlan Price Apply To?
BSH Ingredients’ reference price is based on standard food-grade curdlan requirements corresponding to the Chinese QB/T 4322-2012 Curdlan Standard, while BSH can supply gel strength above the minimum level required by the standard.
Under QB/T 4322-2012, curdlan is divided into Grade I and Grade II.
The principal requirements include:
| Specification | Grade I | Grade II |
|---|---|---|
| Curdlan content, calculated as anhydrous glucose | ≥80% | ≥70% |
| Gel strength, 2% aqueous solution | ≥600 g/cm² | ≥400 g/cm² |
| Total nitrogen | ≤1.0% | ≤1.0% |
| Loss on drying | ≤10.0% | ≤10.0% |
| Ash | ≤6.0% | ≤6.0% |
| pH | 6.0-7.5 | 6.0-7.5 |
QB/T 4322-2012 also specifies requirements for sensory properties, microbiological limits, testing, packaging, transportation, and storage.
BSH Ingredients’ standard curdlan meets the relevant total nitrogen requirement of ≤1.0%, while gel strength can be supplied above the applicable QB/T minimum depending on the product specification.
Buyers requiring 650 g/cm², 800 g/cm², 1,000 g/cm² or other customized gel-strength levels, or particularly low nitrogen levels, should request a separate quotation because these specifications do not have the same production cost as standard curdlan.
What Factors Affect Curdlan Gum Prices?
Two curdlan products described simply as “food-grade curdlan gum” may have significantly different prices. The following factors have the greatest effect on the final curdlan price per kg.
1. Gel Strength
Gel strength is one of the most important factors affecting curdlan gum pricing.
Curdlan is valued for its ability to form thermally induced gels, and different food applications require different levels of gel performance.
The QB/T 4322-2012 minimum gel strength is:
- Grade I: ≥600 g/cm²
- Grade II: ≥400 g/cm²
Commercial customers may request substantially higher performance, including 650 g/cm², 800 g/cm² or even 1,000+ g/cm² depending on the application.
Higher-gel-strength curdlan normally commands a higher price because achieving consistent high gel performance requires tighter control over fermentation, purification, drying, particle characteristics, and batch consistency.
Therefore, buyers should never compare two curdlan quotations without checking the tested gel strength.
2. Total Nitrogen Level
Nitrogen content is another major factor affecting the price.
QB/T 4322-2012 specifies total nitrogen ≤1.0% for both Grade I and Grade II curdlan.
However, some customers require considerably lower values, such as:
- ≤0.5%
- ≤0.3%
- Custom low-nitrogen specifications
Lower-nitrogen curdlan generally requires more intensive purification and process control. Additional purification steps increase manufacturing cost while potentially reducing production yield.
As a result, low-nitrogen curdlan normally costs more than standard food-grade curdlan with otherwise similar specifications.
For buyers requesting both high gel strength and very low nitrogen, the price premium can be particularly significant.
3. Curdlan Content and Product Purity
Curdlan content is another specification that should be checked when comparing supplier prices.
Under QB/T 4322-2012, curdlan content is calculated as anhydrous glucose, with minimum requirements of:
- Grade I: ≥80%
- Grade II: ≥70%
Other quality parameters such as moisture, ash, residual impurities, microbiological limits, and overall batch consistency can also influence manufacturing costs.
A low-priced powder should therefore not automatically be considered equivalent to a more tightly controlled product simply because both are marketed as “curdlan gum.”
4. Purchase Quantity
Order quantity directly affects the bulk curdlan gum price per kg.
A 25 kg trial order cannot normally receive the same unit price as:
- 100 kg
- 500 kg
- 1 metric ton
- Multiple metric tons
- A 10+ metric ton annual purchasing agreement
Larger orders improve production planning, packaging efficiency, logistics efficiency, and inventory management. This generally allows the manufacturer to provide a more competitive unit price.
Buyers with stable annual demand should therefore provide their estimated yearly consumption when requesting a quotation.
5. Packaging, OEM and Private-Label Requirements
Standard bulk curdlan is commonly supplied for industrial food manufacturing, distribution, and further processing.
However, not every buyer wants standard bulk packaging.
BSH Ingredients can also support customers requiring customized solutions, including:
- Custom package sizes
- Custom labels
- Private-label packaging
- OEM services
- Ingredient repacking
- Customized commercial packaging
These services are particularly relevant for Amazon sellers, startup businesses, supplement brands, food brands, ingredient distributors, and companies developing private-label products.
Custom packaging and OEM requirements add additional materials, labor, design, labeling, and production processes, so the final price should be quoted separately from the standard bulk curdlan price.
6. Shipping Destination and Incoterms
When comparing international curdlan quotations, buyers should confirm whether the price is:
- EXW
- FOB
- CIF
- Another agreed delivery term
A factory price in China cannot be directly compared with a landed price delivered to a customer in the United States, Europe, Japan, South Korea, Southeast Asia, or another international market.
Ocean freight, air freight, palletization, export documentation, customs clearance, import duties, insurance, and local delivery can all affect the final landed curdlan gum cost per kg.
Curdlan Gum Price Trend from 2023 to 2026
The Chinese curdlan market has changed significantly during the past three years.
In 2023, supply was relatively tight, and prices remained at comparatively high levels.
During 2024, average prices increased moderately, with internal industry reference data showing an increase of approximately 4.5% for mainstream mid-range domestic curdlan. Rising purification costs and increasing demand for lower-nitrogen products contributed to the firmer market.
The largest change occurred in 2025.
Additional manufacturers entered the curdlan market and production capacity expanded. Competition intensified, particularly in lower-end and standard grades. Industry reference data indicates that average prices for mainstream mid-range products declined by approximately 31% compared with 2024.
The downward movement continued during the first eight months of 2026, although the market has increasingly moved toward a more stable level. Internal market data indicates another decline of approximately 18% compared with the 2025 average.
The important point for buyers is that the decline has not been equal across all specifications.
Basic and lower-end curdlan products have experienced greater price pressure, while high-gel-strength and low-nitrogen grades have maintained stronger pricing.
This is because customized high-performance curdlan requires more demanding fermentation and purification processes and has more limited effective production capacity.
For procurement managers, this means that a general statement such as “curdlan prices are falling” does not necessarily mean that an 800+ g/cm², low-nitrogen specification will decline by the same percentage as a basic food-grade product.
Why the Cheapest Curdlan Gum Is Not Always the Lowest-Cost Choice
When purchasing curdlan, comparing quotations only by price per kilogram can lead to the wrong sourcing decision.
Consider two quotations:
Supplier A: lower price/kg
Supplier B: slightly higher price/kg
Without the specifications, this comparison tells the buyer very little.
A proper curdlan quotation comparison should include:
Price + curdlan content + gel strength + nitrogen level + moisture + ash + microbiological limits + order quantity + packaging + Incoterm
A curdlan product with higher and more consistent gel strength may also allow a food manufacturer to achieve the required texture or gel performance more efficiently in the final formulation.
Consistency between batches is equally important for industrial users. A slightly lower raw material price can quickly become expensive if changing gel performance causes formulation adjustments, production instability, product rejects, or inconsistent finished-product texture.
For B2B sourcing, cost-in-use and specification consistency are therefore often more meaningful than the lowest quoted price per kilogram.

Curdlan Gum Price FAQs
What is the curdlan gum price per kg in 2026?
BSH Ingredients currently offers standard food-grade curdlan from approximately RMB 45/kg as a reference bulk price. The final curdlan gum price per kg depends on gel strength, nitrogen level, curdlan content, quantity, packaging, and delivery terms. High-gel-strength or low-nitrogen customized grades can cost considerably more than standard material.
Why do curdlan gum prices vary so much between suppliers?
Curdlan products sold under the same general name can have different gel strength, nitrogen content, assay, purity, manufacturing quality, packaging, and commercial terms. Some online prices may also be promotional or indicative rather than firm transaction prices. Always request a specification sheet and quotation based on the same quantity and Incoterm before comparing suppliers.
Does higher gel strength increase the curdlan gum price?
Generally, yes. Higher gel strength requires tighter manufacturing and process control. QB/T 4322-2012 specifies minimum gel strengths of 600 g/cm² for Grade I and 400 g/cm² for Grade II, while commercial buyers may require 650, 800, 1,000 g/cm² or higher. Customized high-gel-strength curdlan is normally more expensive than standard material.
Does a lower nitrogen level make curdlan more expensive?
Generally, yes. QB/T 4322-2012 specifies total nitrogen of no more than 1.0%. Customers requiring ≤0.5%, ≤0.3%, or another low-nitrogen specification normally pay a premium because deeper purification and tighter production control are required.
What is the wholesale curdlan gum price for a 1-ton order?
There is no universal 1-ton price because specification matters significantly. A 1-ton standard food-grade order and a 1-ton high-gel-strength, ultra-low-nitrogen order should not be expected to have the same price. Send BSH Ingredients your gel strength, nitrogen level, quantity, packaging, and destination to receive an accurate quotation.
Is laboratory curdlan more expensive than bulk food-grade curdlan?
Yes, by a very large margin. Laboratory curdlan is typically sold in gram-sized packages for research use and includes laboratory-grade specifications, specialized packaging, distribution, and technical services. It should not be compared directly with food-grade curdlan purchased in 25 kg bags or metric-ton quantities.
What is the difference between retail and wholesale curdlan gum prices?
Small packages generally have a much higher price per kilogram because packaging, handling, distribution, inventory, and sales costs are spread across a very small quantity. Factory-direct wholesale orders reduce many of these costs, particularly for pallet and metric-ton purchases.
Can BSH Ingredients provide custom curdlan specifications?
Yes. Buyers can request specifications based on application requirements, including different gel-strength and nitrogen targets. Because customized specifications affect production cost, BSH Ingredients evaluates the technical requirements and purchasing volume before providing the final price.
Does BSH Ingredients offer OEM and private-label curdlan?
Yes. In addition to bulk curdlan supply, BSH Ingredients can support custom packaging, OEM and private-label requirements for qualified projects. These services can be useful for ingredient brands, food companies, Amazon sellers, startups, distributors, and other companies that require packaging beyond standard industrial bulk supply.
How can I get the most accurate curdlan gum quotation?
Provide the supplier with as much purchasing information as possible. At minimum, specify quantity, target gel strength, maximum nitrogen level, required grade or curdlan content, packaging, destination, and preferred Incoterm. This allows BSH Ingredients to quote the appropriate product rather than providing an inaccurate generic price.
