Rice protein peptide is a small-molecule polypeptide extracted from non-GMO rice through enzymatic hydrolysis. It is also known as hydrolyzed rice protein, rice hydrolysate, or rice peptide. Similar to pea peptide, rice peptide has molecules that are much smaller than intact proteins, so it shares the characteristics of being water-soluble, easily absorbable, and hypoallergenic. This natural, plant-based ingredient is suitable for the diet of individuals with cow’s milk protein allergy, is often used as a dietary supplement to support muscle recovery and growth, and due to its good moisturizing properties, is also applied in skincare and hair care products.
Plant Protein Peptide
Rice protein peptide is rich in amino acids such as branched-chain amino acids (BCAAs), glutamine, and arginine. In addition, it is a vegetarian protein peptide that can serve as an alternative to animal protein in plant-based products.
Hypoallergenic
Rice peptide is naturally hypoallergenic and contains no common allergens such as soy, whey, or gluten, making it an ideal choice for protein supplementation in sensitive individuals.
Rapid Absorption
Rice protein peptide, produced through enzymatic hydrolysis, consists of small peptide fragments that are rapidly absorbed and utilized by the body, demonstrating significant advantages in improving nutrient absorption.
High Solubility
Unlike intact proteins, rice peptide is highly water-soluble, and its solubility remains stable across a wide range of pH, salt concentration, and temperature. Therefore, it can be added to clear beverages.
Thermal Stability
Rice peptide has a stable molecular structure and maintains good stability in both high and low temperature environments without gelling.

High-quality rice peptide requires a strict and clean production process. We use automated production equipment to ensure consistent quality and parameters of hydrolyzed rice protein within the same batch.
Hengxin adheres to a green and environmentally friendly philosophy. Its products contain no additives or preservatives; waste materials and wastewater generated during production are all treated in a unified manner.
With over 20 years of export experience in the protein peptide industry, we are dedicated to offering customers high‑quality, cost‑effective products and invite all customers to visit our facility in person.
Food-grade rice peptide (rice protein peptide) has a small molecular weight and offers extremely high digestibility and absorption, hypoallergenic properties, and thermal stability. It is widely used in the formulation of foods, functional nutritional products, and beverages.
Sports Nutrition: Rich in a variety of essential amino acids and high-activity peptides, it provides energy and relieves exercise fatigue. Examples include sports drinks, protein gels, and nutritional supplements.
Infant Formula Foods: Thanks to its easy digestibility, it is highly suitable for infants, the elderly, and other individuals with weak digestive function. It can be added to milk powder and nutritional powders.
Foods for Special Medical Purposes: Used in specialized nutritional formulas, it serves as an ideal alternative protein source for people with lactose intolerance or cow's milk protein allergy.
Meal Replacement and Weight Management: When added to baked goods and protein bars, it increases sustained satiety and protein intake, making it a suitable meal replacement for people managing their weight or reducing body fat.
Professionalism and Focus: Hengxin has focused on the protein peptide industry for over 20 years. It is a high-tech enterprise integrating R&D, production, and sales. Its products comply with ISO 9001, GMP, BRC, FSSC 22000, Halal, and Kosher standards.
Customer Service: We provide one‑stop service support ranging from sample testing and technical consultation to automated production. We offer virtual factory tours and issue authentic product test reports.
Quality Consistency: Hengxin uses modern production equipment to ensure consistent quality, specifications, and parameters for every batch. Customers highly recognize our quality and have established long‑term, stable cooperative relationships with us.
Global Business: We are familiar with the regulatory requirements and quality standards of export markets in more than 30 countries, providing compliance advice to our customers.
Rice protein peptide (also known as rice peptide or rice hydrolysate) is a mixture of small-molecule peptides extracted from rice through enzymatic hydrolysis. Because its molecular weight is much smaller than that of intact protein, it can be rapidly absorbed by the human body and serves as a supplement to provide energy and relieve fatigue.
Key characteristics:
Hypoallergenic: Free of common allergens such as gluten, soy, peanuts, and dairy products, making it a high-quality protein source for individuals with lactose intolerance or cow's milk protein allergy.
Rapid absorption: Composed of 2 to 20 amino acids, it does not require the breakdown steps of protein digestion and can be directly and quickly absorbed by the human intestine.
Thermal stability: Rice peptide is rich in hydrophobic amino acids, which tend to aggregate inside the peptide molecule to form a stable hydrophobic core, thereby resisting heat‑induced molecular unfolding and inactivation.
Rice protein peptide is a product obtained by breaking down large molecules of rice protein into small peptide fragments through enzymatic hydrolysis. Compared with rice protein powder, rice peptide has a lower molecular weight, better water solubility, a higher absorption rate, and is more widely used in functional foods.
When selecting a reliable rice protein peptide supplier, it is important to focus on their production qualifications, product specifications, quality certification systems, and supply stability. In addition, you can also email the administrators of relevant websites to obtain supplier information and qualification documents.
As an experienced manufacturer of gelatin and collagen peptides, Hengxin can provide a range of certificates related to our factory and products, and we offer flexible product supply solutions as well.
