Direct supply from state-of-the-art production facilities under strict ISO and IP-Non-GMO certifications.
The global functional plant protein sector is undergoing a profound paradigm shift driven by technological integration and the scientific optimization of plant-derived raw materials. Central to this transition is hydrolyzed soy protein powder, a highly functional ingredient manufactured through controlled enzymatic hydrolysis. By parsing soy protein isolates or concentrates into shorter chain oligopeptides and free amino acids, manufacturers unlock critical properties including structural stability, solubility across a wide range of pH levels, high water binding capacity, and superior emulsification.
Our raw soybean materials are sourced from controlled Non-GMO IP (Identity Preserved) planting bases, ensuring chemical consistency, zero genetic modification contamination, and a minimal environmental footprint. Industrially, the product serves as a vital component in meat processing, vegan analog creation, nutritional beverage formulation, performance supplements, cosmetics, and fermentation industries. Leveraging advanced processing systems from global leaders such as DACHUANYUAN spray drying towers, our group delivers superior product standardization characterized by uniform particle size, fast dispersion profile, and clean organoleptic properties.
"As global food manufacturers demand clean-label, plant-based emulsifiers with stable thermal tolerances, our enzymatic processing technologies isolate target proteins to optimize molecular weights. This yields hydrolyzed soy protein with superior nitrogen solubility indexes (NSI) and unmatched flavor neutrality."
How Shandong Kawah Oils & Guanxian Xinrui Industrial achieve consistent functional properties.
The manufacturing process of hydrolyzed soy protein powder begins with defatted Non-GMO soybean flakes. Through structural extraction steps, soluble carbohydrates and non-protein constituents are isolated and separated, leaving a high-purity soy protein isolate (ISP). Our advanced factory implements enzymatic hydrolysis utilizing precise protease combinations (exopeptidases and endopeptidases) under strictly controlled pH and temperature regimes. This allows us to target specific peptide bonds to control the final Degree of Hydrolysis (DH).
By modulating the DH value, we engineer different product lines. Low DH hydrolyzed soy proteins maintain higher molecular weight chains which are optimal for forming highly stable gel matrices in meat emulsion systems. Conversely, high DH hydrolyzed soy proteins exhibit superior solubility, clear dispersion, and complete thermal stability even in highly acidic conditions, making them ideal for plant-based sports beverages, protein fortifications, and clinical nutritional formulas. Once hydrolyzed, the liquid mixture is clarified using industrial tri-canter separators, concentrated, and processed through high-efficiency DACHUANYUAN spray dryers. This locks in the structural integrity of the peptides, preventing oxidation and preserving nutritional value.

A diversified industrial group processing agricultural materials with high efficiency and low waste.
Founded in May 2003, Xinrui Group spans over 1,000 mu. The group integrates industrial operations including green cogeneration, municipal urban heating, and gaseous fuel supply. Under this structure, we operate two main agricultural processing subsidiaries: Guanxian Xinrui Industrial Co., Ltd. (which processes 500,000 tons of wheat flour annually into vital wheat gluten, wheat starch A, wheat starch B, and ethanol) and Shandong Kawah Oils Co., Ltd. (which processes 180,000 tons of Non-GMO soybeans annually into food-grade soybean meal, isolated soy protein, and dietary fibers).
By using wheat starch B and pentosan to produce industrial ethanol and premium animal feed, we have formed a comprehensive, waste-free, circular economy loop. Our specialized trading arm, Guanxian Ruichang Trading Co., Ltd., exports these plant-based isolates, fibers, and starches directly to customers overseas, representing over 70% of the group's total production capacity. The scale of our operations, advanced equipment configurations, and rigorous quality systems place our group at the forefront of the global bio-refinery sector.
How our hydrolyzed protein powder meets formulation demands across diverse markets.
Hydrolyzed soy protein has unique properties that make it useful in many industries. For example, in the meat processing industry, it is used to formulate emulsions because it binds water and fat efficiently. This helps reduce weight loss during cooking and improves texture. The protein's chemical properties allow it to hold fat and water within the matrix during thermal processing, which is key for applications like sausages and meatballs.
For beverages, the protein powder is processed to have a high nitrogen solubility index (NSI) and low viscosity. This makes it suitable for ready-to-drink (RTD) protein shakes, powdered sports drinks, and dairy-alternative products. It remains stable at low pH levels and does not precipitate, ensuring a smooth texture and long shelf life. Additionally, its high amino acid profile makes it a useful nitrogen source for fermentation and cosmetic products, where it helps with skin conditioning and moisture retention.
