Soy Protein Hydrolysate (SPH) represents the pinnacle of modern dietary protein technology. Unlike standard Isolated Soy Protein (ISP) or concentrates, SPH is produced via highly controlled enzymatic hydrolysis of food-grade, Non-GMO soy source material. This biochemical process breaks intact protein peptide chains down into lower molecular weight peptides and free amino acids, mirroring the natural digestive processes of the human gastrointestinal tract.
By pre-digesting these molecular bonds, we yield a highly soluble, rapidly absorbable protein powder featuring an excellent Nitrogen Solubility Index (NSI) across a wide range of pH levels. These low-molecular-weight peptides act as bioactive compounds, demonstrating rapid assimilation profiles that make them ideal for specialized nutrition industries globally.
For procurement professionals and product formulators, choosing a high-quality SPH involves analyzing parameters such as the **Degree of Hydrolysis (DH)**, the exact **molecular weight distribution profile (often targeted below 2000-5000 Daltons)**, and the sensory balance. Raw material purity is guaranteed through strict Non-GMO supply chain controls, beginning directly from our contracted agricultural bases.
As supply chains face increasing disruptions, enterprise buyers require manufacturers that own complete raw material integration and exhibit robust circular economic resilience.
Global food, supplement, and pharmaceutical brands encounter severe risks regarding raw material contamination, genetically modified contamination, and supply fluctuations. As an industry pioneer, **Xinrui Group** overcomes these bottlenecks by establishing vertical integration across the entire agricultural deep-processing value chain. Our non-GMO soybean and wheat cultivation bases feed directly into our massive processing complexes, ensuring trace-to-source clarity and pricing stability.
Through our dedicated trading entity, **Guanxian Ruichang Trading Co., Ltd.** (founded in 2011 with 6 million yuan registered capital), we facilitate factory-direct exports to international ports. Over 70% of our group’s production capacity is exported directly, providing competitive cost advantages by removing unnecessary middle-tier logistics margins. Our infrastructure handles large-volume container contracts with precision documentation tailored to diverse global customs environments.
Sustainability is no longer an option but a core requirement for enterprise ESG compliance. Founded in May 2003, **Xinrui Group** spans an area of more than 1,000 mu with an annual output value of 2.8 billion Yuan. We operate cogeneration systems, municipal heating, gas supply, and deep wheat and soybean processing lines.
Our wheat circular economy is highly advanced: processing 500,000 tons of wheat flour annually, we deploy German-imported tri-canter separation technology to manufacture vital wheat gluten and high-purity wheat starch. Starch byproducts and pentosans are instantly funneled into high-grade ethyl alcohol and animal feed production. This closed-loop configuration minimizes industrial waste, guarantees lower carbon footprint metrics, and yields maximum cost efficiencies transferred directly to our global purchasers.
How we transform raw non-GMO soy flakes into highly soluble, allergen-reduced bioactive peptides.
We source premium Domestic Non-GMO soybeans, extracting low-temperature food-grade soy meal under strict IP protection protocols.
Utilizing high-purity food-grade endopeptidases and exopeptidases to cleave specific peptide linkages without generating bitter compounds.
Advanced ultrafiltration systems isolate fractions based on target molecular weights, removing unhydrolyzed proteins and allergens.
High-capacity DACHUANYUAN spray drying towers process the liquid peptides into micro-granulated, dust-free, and instantly soluble powder.
Soy Protein Hydrolysate powder acts as a functional cornerstone across diverse industrial formulations.
Due to the pre-digested nature of low molecular weight peptides, SPH is easily tolerated by patients with impaired gastrointestinal function. It provides a hypoallergenic, rapid nitrogen source for medical recovery formulas and hypoallergenic infant nutrition.
Perfect for pre-workout, post-workout, and RTD protein beverages. SPH features a high concentration of Branched-Chain Amino Acids (BCAAs). Its high solubility prevents grittiness and sediment formation, delivering rapid muscle replenishment.
SPH serves as an organic nitrogen source in microbiological growth media. It accelerates microbial proliferation, enzyme expression, and secondary metabolite yields in biopharmaceutical and fermentation setups.
Established in 2014 with a registered capital of 120 million Yuan, **Shandong Kawah Oils Co., Ltd.** is a leading agricultural industrialization enterprise in Shandong Province. Our plant integrates planting, scientific R&D, deep soybean fractionation, and export capabilities. We process over 180,000 tons of domestic non-GMO soybeans annually.
Our extraction lines extract non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and soy dietary fibers sequentially. The core of our facility is the spray drying tower manufactured by **DACHUANYUAN**, representing the largest single production line capacity in China. Our advanced engineering allows us to control the protein dispersion index, bulk density, and particulate structure to deliver superior powder characteristics demanded by international partners.
We align our manufacturing standards with worldwide import requirements, verified through third-party audits.
*Our products are also certified under IP-NON GMO standards, guaranteeing clean-label claims for global health markets.

Isolated Soy Protein contains intact soy globulin proteins (mostly glycinin 11S and beta-conglycinin 7S) with a molecular weight ranging from 150k to over 300k Daltons. SPH is subjected to controlled enzymatic digestion, breaking these large macromolecules into highly absorbable oligopeptides and short-chain di/tri-peptides, typically under 5,000 Daltons. This shifts the solubility dynamics, digestion kinetics, and allergen profiles of the final product.
We are a diversified industrial group named Xinrui Group, integrating raw material cultivation, processing, and direct export. Our subsidiary, Shandong Kawah Oils Co., Ltd., processes 180,000 tons of soybeans annually and serves as our dedicated isolated soy protein and hydrolysate manufacturer. Our wheat-processing division, Guanxian Xinrui Industrial Co., Ltd., processes 500,000 tons of wheat flour annually to manufacture vital wheat gluten and starches. Direct export transactions are managed via Guanxian Ruichang Trading Co., Ltd.
We maintain a strict Identity Preservation (IP) program. All soybeans are sourced from domestic Non-GMO zones under contracted farming arrangements. Raw materials are audited upon arrival at our processing centers and verified via PCR testing at third-party laboratories. Every batch is traceable back to its planting source, allowing us to maintain IP-NON GMO certification.
Our facilities are fully certified under HACCP, ISO9001, ISO22000, BRC (British Retail Consortium), HALAL, KOSHER, IP-NON GMO, and audited by SGS. We can support additional compliance document requests depending on the target country’s food safety regulations.
Because our wheat processing generates starch byproducts that feed into our municipal cogeneration, ethanol production, and animal feed plants, we recover maximum commercial utility from every ton of raw material. This optimization mitigates volatility in our overhead expenses, enabling us to provide long-term stable pricing contracts for our global B2B clients, even during periods of crop price volatility.
With factory lines exporting over 70% of our capacity, we offer flexible shipping options, including FOB, CFR, CIF, and DDU. Typical lead times range between 2 to 4 weeks from order confirmation, depending on specific customized particle distributions, moisture specifications, or packaging configurations (such as 20kg bags or bulk super sacks).
