Yongchuan Douchi Powder — Fermented Black Bean Seasoning (LSP-H11)

Yongchuan Douchi Powder — Fermented Black Bean Seasoning for Soup Base (LSP-H11)

Yongchuan douchi powder LSP-H11 is a spray-dried fermented black bean powder made from Yongchuan fermented black beans (douchi) — a traditional Chinese fermented ingredient with over 300 years of production history in Chongqing. The fermented black beans are blended with acid hydrolyzed vegetable protein seasoning liquid, maltodextrin, refined salt, and caramel color, then sterilized and spray-dried into a dark brown, free-flowing powder.

This Yongchuan douchi powder preserves the strong fermented umami character of traditional douchi in powder form. The measured amino nitrogen is 1.38 g/100g, substantially higher than standard soy sauce powders, which means more umami impact at lower inclusion rates. For food manufacturers, this Yongchuan douchi powder solves the practical problems of working with whole fermented beans: no soaking, no chopping, no paste handling, no refrigeration.

3-MCPD was not detected in the most recent batch. The product is manufactured under ISO 9001, HACCP, and Halal certification. For context on traditional fermented soybean products and their production, the douchi entry on Wikipedia provides background on fermentation methods and regional varieties.

Yongchuan Douchi Powder Specifications

Applications of Yongchuan Douchi Powder

Recommended dosage: 0.5-5% of total formulation, adjustable by application. This Yongchuan douchi powder disperses quickly in hot water and blends evenly into dry compound mixes.

Instant Noodle and Soup Base Seasoning

This Yongchuan douchi powder disperses quickly in hot water (above 80°C) and delivers an immediate fermented bean top note at 1-3% inclusion. The high amino nitrogen level (1.38 g/100g) means less MSG or yeast extract may be needed to reach your target umami profile. In soup base applications, this Yongchuan douchi powder builds the savory middle layer that makes instant broths taste complex rather than thin. Replacing 30% of the MSG contribution with this Yongchuan douchi powder maintained the same panel-rated umami intensity while adding fermented complexity.

Hot Pot Base and Catering Seasoning

Blend into dry hot pot bases and catering seasoning mixes at 1-3%. This Yongchuan douchi powder adds authentic douchi depth without the processing steps, texture issues, or refrigeration that whole fermented black beans require. In Sichuan-style hot pot base formulations, 2% Yongchuan douchi powder combined with chili and Sichuan pepper creates a layered savory profile with restaurant-level complexity.

Compound Seasoning and Flavor Systems

Use this Yongchuan douchi powder as a base note in compound seasoning formulations at 0.5-2%. It pairs with chili, Sichuan pepper, garlic, and star anise profiles, adding fermented complexity without dominating the blend. The total acid content (2.79 g/100g as lactic acid) provides a natural tang that complements tomato-based, vinegar-based, and chili-based sauce systems. For guidance on umami synergy in savory formulations, see the umami overview for background on glutamate and nucleotide interactions in fermented ingredients.

Kitchen and Foodservice Standardization

For restaurant chains and central kitchen operations, this Yongchuan douchi powder replaces whole fermented black beans in recipe standardization. Consistent batch-to-batch umami, no preparation steps, and no refrigeration needed. One gram delivers roughly the fermented umami impact of 3-4 grams of whole Yongchuan douchi in liquid-based applications.

Sauce and Condiment Manufacturing

Incorporate this Yongchuan douchi powder into dry sauce mixes, bouillon bases, and condiment powders. At 3-5%, it serves as the primary fermented character ingredient, reducing or eliminating the need for whole fermented black bean paste in the formulation.

What Makes Yongchuan Douchi Different

Yongchuan douchi from Chongqing is one of China’s most recognized fermented black bean products, distinguished by its glossy black appearance, strong savory aroma, and complex umami character developed through natural mold fermentation using Aspergillus oryzae. Unlike quick-fermented bean pastes, Yongchuan douchi undergoes extended fermentation — typically 4-6 months — that produces higher levels of free amino acids and peptides. This is why this Yongchuan douchi powder measures 1.38 g/100g amino nitrogen compared to the 0.6-1.0 g/100g range typical of standard fermented soy products. For food manufacturers, this means more flavor impact per gram and a fermented character that reads as “slow-cooked” and “artisanal” in the final product.

Frequently Asked Questions

What is the difference between this Yongchuan douchi powder and whole fermented black beans?

One gram of this Yongchuan douchi powder delivers roughly the fermented umami impact of 3-4 grams of whole Yongchuan douchi in liquid-based applications, without the texture, preparation, or storage requirements of whole beans. This Yongchuan douchi powder provides the fermented character in a dispersible, shelf-stable format that works in dry blend applications where whole fermented black beans cannot be used.

Is this Yongchuan douchi powder suitable for Halal production lines?

Yes. This Yongchuan douchi powder is manufactured under Halal certification. All raw materials are plant-based. There are no animal-derived ingredients, no alcohol in the process, and no cross-contamination risk from shared equipment.

What gives this Yongchuan douchi powder its dark brown color?

The dark brown color comes primarily from the natural fermentation of the Yongchuan fermented black beans, which develop deep melanoidin pigments during the 4-6 month aging process. A small amount of caramel color is added to standardize the color across production batches.

Can this Yongchuan douchi powder replace douchi paste in a recipe?

Yes. For dry blend applications, this Yongchuan douchi powder at 1-3% replaces the fermented character contribution of douchi paste with dry-handling convenience. For wet applications, it disperses directly into the liquid phase without pre-soaking or chopping whole fermented black beans.

What level of 3-MCPD does this Yongchuan douchi powder contain?

3-MCPD was not detected in the most recent production batch (detection limit 0.01 mg/kg). This Yongchuan douchi powder is suitable for export to markets with the strictest 3-MCPD limits.

Does this Yongchuan douchi powder contain any allergens?

Contains soybean-derived ingredients (fermented black soybeans and acid hydrolyzed vegetable protein from soy). Does not contain wheat, dairy, egg, fish, crustacean, tree nut, or peanut allergens.

What is the amino nitrogen level and why does it matter for this Yongchuan douchi powder?

Measures 1.38 g/100g amino nitrogen, substantially higher than standard soy sauce powders. Amino nitrogen reflects free amino acids and peptides — the molecules responsible for umami. This Yongchuan douchi powder delivers more flavor impact per gram, enabling lower usage rates of MSG or yeast extract.

What are the MOQ, lead time, and sample policy?

MOQ is 1 MT. A 1 kg evaluation sample is available. Standard lead time is 15-20 working days. Our trade team can provide current scheduling and accommodate rush orders.
