Applications
Where buyers use papain in production. Papain breaks proteins into smaller peptides, so it is bought wherever controlled protein breakdown improves texture, clarity or processing. Tell us your application and we will quote the grade that fits it.
Commercial Meat Tenderizing
Breaks down collagen and myofibrillar proteins in tough beef, pork, and poultry cuts for improved tenderness and bite.

Frequently Asked Questions
Q1 What is Papain (EC 3.4.22.2) and what does it do?
Papain is a cysteine protease from green papaya latex that hydrolyzes proteins into smaller peptides and amino acids, enabling tenderness, clarity, digestibility, residue breakdown, and controlled proteolysis in multiple industries.
Q2 What are the recommended pH and temperature for Papain?
For best performance, use Papain within pH 5.0–8.0 and 60°C–70°C. Actual dosing and conditions should be confirmed in your application trials.
Q3 How should I choose an activity grade (6,000–30,000 USP units/mg)?
Higher USP activity typically allows faster protein breakdown at the same dosage. Select the grade that best matches your target reaction time, formulation constraints, and cost-per-performance.
Q4 Is this Papain suitable for food and supplement use?
Yes. Certifications include USP/FCC, Food Grade, ISO 9001, HALAL, and KOSHER. We can provide COA/TDS upon qualified inquiry.
Q5 How do I store Papain to maximize shelf life?
Store sealed in a cool, dry place. Keep away from moisture to help maintain activity. The shelf life is 24 months under proper storage conditions.
Q6 How do I request a wholesale quote?
Send the product or activity grade, the quantity per order or per month, the destination country (and port if shipping by sea) and your application to hello@mail.enzymecontact.com or through the quote form. Prices and lead times are quoted per order.
Q7 Do you supply distributors and resellers?
Yes. We quote for manufacturers, ingredient distributors and resellers. Tell us the markets you sell into and the pack sizes you need (1 kg, 5 kg or 25 kg), and ask for the documents your customers expect.
