Product Overview

National Patent Rice Bran Protein Extraction Technology

The Huatai Rice Bran Protein Plant employs our nationally patented technology (ZL200920089515.8) to extract high-quality, hypoallergenic protein from rice bran — a widely available but underutilized by-product of rice milling. Rice bran contains 12-16% protein with excellent nutritional properties, yet its rapid lipase-driven rancidity has historically limited protein extraction. Our integrated process solves this challenge through in-situ stabilization followed by enzymatic hydrolysis and membrane separation, achieving protein purity ≥80% and extraction yields ≥60%. The resulting rice bran protein is hypoallergenic and highly digestible, making it ideal for infant formula, sports nutrition and medical applications. Available in capacities from 10 to 100 TPD of rice bran.

Rice Bran Stabilization

Fresh rice bran contains active lipase enzymes that rapidly degrade oil to free fatty acids — FFA can increase from 5% to 50% within days. Our stabilization system uses controlled heat treatment to inactivate lipase, preserving both the oil and protein quality for subsequent extraction.

Enzymatic Hydrolysis of Protein

Stabilized rice bran undergoes controlled enzymatic hydrolysis using food-grade proteases. The enzymes break down the protein matrix, releasing soluble protein fractions while maintaining the amino acid profile. Temperature, pH and enzyme dosage are precisely controlled for optimal yield.

Membrane Separation & Concentration

The hydrolyzed slurry passes through ultrafiltration membranes that separate protein from carbohydrates, fiber and other non-protein components. The concentrated protein retentate achieves ≥80% purity on a dry basis, while the permeate contains soluble sugars and small peptides.

Spray Drying

The concentrated protein solution is spray-dried into fine powder using a centrifugal atomizer. Inlet and outlet temperatures are optimized to preserve protein functionality and solubility while achieving the target moisture content below 6%.

Protein Powder Packaging

The dried rice bran protein powder is cooled, sieved and packaged in moisture-proof bags. The finished product is a light-colored, fine powder with ≥80% protein content, neutral flavor and excellent solubility for use in food and nutritional applications.

National Patent Technology

Our rice bran protein extraction process is protected by Chinese national patent ZL200920089515.8, covering the integrated process of stabilization, enzymatic hydrolysis and membrane separation. This proprietary technology achieves protein purity above 80% with extraction yields exceeding 60%.

≥80% Protein Purity

The membrane separation stage precisely isolates the protein fraction, achieving purity levels of 80% and above on a dry basis. This high-purity protein is suitable for demanding applications including infant formula, medical nutrition and sports supplements where protein quality is critical.

Integrated Stabilization

Our process includes integrated rice bran stabilization as the first step, inactivating lipase enzymes that would otherwise rapidly degrade the bran's oil and protein. This ensures consistent raw material quality regardless of storage time between milling and processing — a critical advantage for commercial-scale operations.

Nutritional Supplements

Rice bran protein's complete amino acid profile and high digestibility make it ideal for protein supplements, meal replacement shakes and weight management products where hypoallergenic properties are valued.

Sports Nutrition

The excellent amino acid profile and rapid absorption of rice bran protein support muscle recovery and growth. Its hypoallergenic nature makes it suitable for athletes with dairy or soy sensitivities.

Functional Foods

Rice bran protein adds nutritional value and functional properties to bakery products, beverages and health foods. Its neutral flavor and good solubility make it easy to incorporate into existing formulations.

Cosmetics

Rice bran protein is used in premium skincare and hair care products for its moisturizing, film-forming and antioxidant properties. It provides a natural, plant-based protein source for clean beauty formulations.

Why is rice bran stabilization necessary?

Rice bran contains active lipase enzymes that rapidly degrade oil to free fatty acids (FFA can increase from 5% to 50% within days). Stabilization by heat treatment inactivates lipase, preserving the oil and protein quality. Without stabilization, the increasing FFA levels degrade both the oil value and the protein's nutritional quality, making extraction impractical.

What is the patent technology?

Patent ZL200920089515.8 covers our integrated process combining rice bran stabilization, enzymatic hydrolysis and membrane separation to extract high-quality protein from rice bran with purity above 80%. This patent-protected technology ensures consistent protein quality and yield, and is exclusively available from Huatai Oil Machinery.

What is rice bran protein used for?

Rice bran protein is hypoallergenic and easily digestible, making it ideal for infant formula, sports nutrition, medical nutrition products and functional food ingredients. Its excellent amino acid profile, neutral flavor and high solubility distinguish it from other plant proteins, commanding premium prices in the specialty protein market.
