Product Description

Product Description

Our Soy Peptone is a premium, animal-free protein hydrolysate meticulously crafted from high-quality non-GMO soybeans, designed to deliver consistent, reliable nutrition for a wide range of biotechnological, microbiological, and industrial applications.

A leading plant-derived peptone — sustainable, safe, and aligned with the global shift toward clean-label products and eco-friendly bioprocessing practices.

Produced through advanced enzymatic hydrolysis (using papain or other food-grade enzymes) and rigorous purification processes, our Soy Peptone is a water-soluble powder characterized by a balanced profile of free amino acids, small peptides, essential growth factors, vitamins, and carbohydrates—all of which are critical for supporting robust microbial growth, cell proliferation, and metabolic activity. Unlike animal-derived peptones, our soy-based formula eliminates the risk of cross-contamination with animal pathogens (such as those associated with mad cow disease).

Our Soy Peptone is backed by comprehensive quality documentation, including Certificates of Analysis (CoA), Safety Data Sheets (SDS), and compliance with international standards. We are committed to providing a product that not only meets but exceeds customer expectations, offering technical support to help optimize its use in specific applications. Whether you are in biotechnology, microbiology, pharmaceuticals, food and beverages, or cosmetics, our Soy Peptone delivers the reliability, safety, and performance you need to drive innovation and efficiency in your processes.

Join the global shift toward sustainable, plant-based nutrient solutions with our premium Soy Peptone—your trusted partner for high-performance, compliant, and eco-friendly bioprocessing and industrial applications.

Frequently Asked Questions
Q What makes Soy Peptone different from animal-derived peptones?
Soy Peptone is a 100% plant-derived, animal-free protein hydrolysate produced from non-GMO soybeans. Unlike animal-derived peptones, it eliminates the risk of cross-contamination with animal pathogens such as those associated with mad cow disease (BSE/TSE), making it a safer and more sustainable choice for bioprocessing and pharmaceutical applications.
Q What grades of Soy Peptone are available?
Our Soy Peptone is available in three grades: Industrial Grade, Pharmaceutical Grade, and Reagent Grade. Each grade is tailored to meet specific application requirements, with the Reagent Grade offering stricter amino nitrogen levels (≥3.0%) and a tighter pH range (6.8–7.2).
Q Can the product specifications be customized?
Yes. While the physicochemical index listed represents our general specification, we offer product customization to meet specific customer requirements. We also support OEM packaging and custom packaging sizes upon request.
Q What quality documentation is provided with the product?
Each batch of our Soy Peptone is supported by comprehensive quality documentation including a Certificate of Analysis (CoA) and a Safety Data Sheet (SDS). The product is manufactured in compliance with applicable international quality standards.
Q In which industries is Soy Peptone commonly used?
Soy Peptone is widely used across multiple industries including biotechnology, microbiology, pharmaceuticals, food and beverages, and cosmetics. It serves as an effective nitrogen and nutrient source for microbial culture media, fermentation processes, and cell growth applications.
Q How should Soy Peptone be prepared before use?
Soy Peptone should be fully dissolved in water and then sterilized prior to use. Please follow your specific protocol or contact our technical support team for guidance on optimizing preparation for your particular application.
