B2B Food formulation requirements have shifted from simple thickening agent additions to complex macromolecular structuring. Isolated Soy Protein (ISP) serves as a cornerstone in this transformation.
Within modern soup manufacturing, achieving the perfect velvety mouthfeel—traditionally provided by dairy fats or slow-rendered bones—without adding unnecessary cholesterol, fat, or off-flavors is a major technical challenge. This is where high-gel, emulsion-type ISP (such as our 9007B-A and 9007B-C) plays an essential structural role.
When ISP is introduced into aqueous thick soup systems, its globular proteins unfold during heating, exposing hydrophobic sites that bind with dispersed lipid droplets. Simultaneously, hydrophilic amino acid chains align with water molecules, establishing a tight, viscoelastic protein-water-fat matrix. This prevents phase separation during sterilization processes like retorting or high-temperature UHT treatments.
Using ISP in commercial soups goes beyond simple viscosity control. Our high-emulsion grades act as functional stabilizers that improve opacity, simulate creamy mouthfeel, and maintain structural integrity across varying temperature stages (freeze-thaw stability, warm buffet line holds, and microwave cooking).
Key market forces shaping the international plant-protein B2B sector, driven by consumer demand and supply chain developments.
Global retail networks are actively replacing chemically modified starches and emulsifying salts (like phosphates) with clean-label plant proteins. ISP serves as a clean alternative that offers thickening, stabilization, and protein fortification all under a single, consumer-friendly label.
With convenience foods on the rise, dry soup mixes require proteins that disperse instantly in hot water without clumping. Dispersion-type ISPs like our 9030 or 9032 are engineered to hydrate quickly and smoothly without needing high-shear blending.
Regulatory bodies continue to push for reduced sodium and fat in packaged foods. High-performance ISP helps food scientists offset the loss of texture and mouthfeel that occurs when fat and salt are reduced in ready-to-eat cream soups.
How Xinrui Group leverages fully integrated, closed-loop refining technologies to maintain global cost leadership and quality standards.
Established in May 2003, Xinrui Group spans a total area of more than 1,000 mu, achieving an annual output value of 2.8 billion Yuan. We operate dynamic, vertically integrated agricultural processing clusters. This includes our subsidiary, Shandong Kawah Oils Co., Ltd. (est. 2014, registered capital of 120 million Yuan), which processes 180,000 tons of domestic Non-GMO soybeans annually.
Our facility houses the largest single-line spray drying tower in China, imported from DACHUANYUAN. This system processes high-grade soy flakes into premium Isolated Soy Protein (ISP) at a scale exceeding industry norms. This automated technology helps ensure precise control over protein denaturation, particle size, and functional consistency across every batch.
For our wheat chain, Guanxian Xinrui Industrial Co., Ltd. (est. 2007, registered capital of 100 million Yuan) processes 500,000 tons of wheat flour annually. Our advanced tri-canter separation system operates in a completely closed, hygienic circuit. This setup allows us to refine wheat into vital wheat gluten and starch, utilizing starch B and pentosan for eco-friendly ethanol and animal feed production.
From European food processors to Asian catering brands, bulk buyers rely on our functional proteins to solve distinct operational challenges.
For universities, hospitals, and corporate cafeterias, soups must remain hot in steam tables for hours. Standard starches often break down and lose viscosity under prolonged heat. Using a tailored ISP-wheat starch matrix keeps soup bases thick and emulsified without skinning or separating.
Food brands require dry ingredients with long shelf lives, low moisture, and consistent hydration. Our Non-GMO soy dietary fiber (SDF) and dispersion protein 9030 dispersion types disperse smoothly in warm water, creating a rich texture instantly.
Formulating vegan alternatives to traditional creamed soups requires replicating the creaminess of dairy. Our emulsion-type ISP forms stable fat-water networks with vegetable oils, creating a dairy-free cream base with the right opacity and viscosity.

Providing direct-from-factory logistics, reliable quality control, and vertical integration to global markets.
Founded in 2011 with 6 million Yuan in registered capital, Guanxian Ruichang Trading Co., Ltd. serves as the dedicated export window for Xinrui Group. We export isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol directly to international buyers.
Exporting over 70% of our group’s production capacity, we offer a direct line to our manufacturing facilities. This vertical integration allows us to coordinate production schedules, raw material sourcing, and logistics efficiently, providing consistent pricing and reliable supply lines.
We work closely with clients to supply custom-spec plant proteins and starches, serving major food production hubs across Europe, the Americas, Southeast Asia, and the Middle East.
Partner with our application laboratory to develop customized viscosity and protein fortification profiles matching your target formulas.
Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) was set up in 2007 with 100 million Yuan in registered funds. We utilize modern separation and extraction technologies to adjust parameters like water-binding capacity, oil-emulsification index, and slurry viscosity to meet your product requirements.
Essential technical, logistical, and compliance details for global sourcing teams.
We are an integrated group company named Xinrui Group. Our subsidiary, Shandong Kawah Oils Co., Ltd., handles isolated soy protein production with an annual capacity of 50,000 tons. Guanxian Xinrui Industrial Co., Ltd. processes vital wheat gluten with a capacity of 30,000 tons per year. Our export division, Guanxian Ruichang Trading Co., Ltd., manages international logistics and sales directly from our factories.
We hold HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, IP-NON GMO, and SGS certifications. We can also arrange additional third-party testing and documentation depending on local import requirements.
For thick soups, dry mixes, and instant beverage systems, we recommend dispersion types like 9030 or 9032 because they hydrate quickly without clumping. For meat emulsions and canned soups that undergo high-heat retorting, we recommend high-gel, emulsion-type proteins like 9007B-A or 9007B-C, which maintain a stable fat-and-water emulsion under high thermal shear.
We maintain a strict Identity Preservation (IP) program. This starts with our dedicated domestic planting bases and runs through processing, storage, and shipping. Every batch undergoes PCR testing to verify genetic purity before export.
