Products Description
Harness the natural power of one of the world's most versatile proteolytic enzymes. Our Papain Enzyme Powder is a high-potency, purified extract sourced from the latex of the Carica papaya fruit. As a trusted B2B supplier to the global nutraceutical, food processing, and pharmaceutical industries, we provide a reliable, consistent, and effective enzymatic solution for your most demanding formulations.
Papain is a cysteine protease renowned for its robust ability to hydrolyze proteins, breaking them down into smaller peptides and amino acids. This plant-based, vegan-friendly enzyme offers a superior and sustainable alternative to animal-derived or synthetic processing aids. We are committed to delivering a product that meets the highest standards of purity and activity, batch after batch.
Product Source & Botany
The quality of an enzyme begins at its source. We ensure traceability and purity from the orchard to your facility.
* Botanical Source: Carica papaya L. (Caricaceae family)
* Part Used: The enzyme is extracted from the latex obtained by making shallow incisions on the skin of unripe, green papayas. The fruit is at its peak enzymatic activity during this stage of maturity.
* Cultivation & Sourcing: Our papaya is sourced from select plantations that adhere to stringent agricultural practices. We prioritize partners who employ sustainable farming methods, ensuring the raw material is free from contaminants and of consistently high quality.

Production Process: Precision and Purity
Our advanced manufacturing process is designed to maximize enzymatic yield and stability while guaranteeing purity.
* Sustainable Tapping: Latex is collected from unripe papayas using a controlled, non-destructive scoring technique that preserves the tree's health.
* Immediate Stabilization: The raw latex is immediately filtered and stabilized to prevent microbial growth and enzymatic denaturation.
* Ultra-Filtration & Purification: A multi-stage cold filtration and purification process removes plant solids, impurities, and inactive proteins.
* Controlled Spray-Drying: The purified liquid extract is converted into a fine powder using low-temperature spray-drying, a critical step to preserve the enzyme's delicate three-dimensional structure and activity.
* Standardization & Blending: The powder is meticulously blended with a food-grade carrier to achieve the specified, consistent activity level required by our clients.
* Rigorous QC & Packaging: The final product undergoes a battery of tests, including microbiological and enzymatic activity assays, before being packaged in moisture-resistant, food-grade containers.
Our manufacturing facilities are ISO 22000, FSSC 22000, and HACCP certified, ensuring international standards of quality and food safety are met at every stage.
Key Product Features
* Exceptionally High Proteolytic Activity: Consistently high USP potency (1.5M - 2M U/mg) for superior performance in demanding applications.
* 100% Plant-Based & Vegan: An ideal, sustainable choice for clean-label and vegan product lines.
* Non-GMO & All-Natural: Sourced from non-genetically modified papaya, with no synthetic additives or preservatives.

Frequently Asked Questions (FAQ)
Q1: Is Papain suitable for vegetarian and vegan products?
A: Yes, absolutely. It is 100% plant-based, derived solely from the papaya fruit, making it perfectly suited for vegan and vegetarian formulations.
Q2: How does Papain differ from Bromelain or Ficin?
A: While all three are plant-based cysteine proteases, they originate from different sources (Papaya, Pineapple, and Fig, respectively) and have slightly different protein cleavage specificities and optimal activity profiles. Papain is known for its broad substrate specificity and high stability, often making it a preferred choice for general-purpose protein hydrolysis.
Q3: What is the typical lead time for bulk orders?
A: For standard grades, we can ship within 7-10 working days. Lead times for very large or custom-formulated orders will be confirmed upon inquiry.
Q4: Can you produce custom enzyme blends containing Papain?
A: Yes. As a core manufacturer, we specialize in creating custom enzyme blends (e.g., Papain with Bromelain, Amylase, or Lipase) to meet your unique application requirements.
Q5: What is the shelf life, and how should I store it?
A: The standard shelf life is 24 months from the production date when stored in its original, sealed packaging under recommended cool, dry conditions.
Q6: Do you offer samples for product development and testing?
A: Yes, we provide product samples to qualified B2B clients. Please get in touch with our technical sales team with your company information and intended use.
