Liquid Papain 80,000 U

What is papain good for?

Beer and beverage clarification: prevents haze caused by proteins.

Meat tenderizing: softens meat by breaking down protein.

Food processing: produces protein hydrolysates, improves dough and cheese texture.

Cosmetics: used in exfoliating and skin-smoothing products.

Industrial use: applied in leather dehairing and textile finishing.

1.Beer clarification:

Papain acts as a natural protease in beer clarification, breaking down soluble proteins and polypeptides that cause turbidity. It improves beer's clarity and stability, ensuring a bright appearance without affecting flavor, with dosage adjusted based on raw material properties and brewing conditions.

2.Vinegar clarification:

In vinegar clarification, Papain hydrolyzes haze-forming proteins and colloidal substances from raw materials like grains or fruits. It enhances vinegar's transparency and shelf life, maintaining its original taste and nutritional value while simplifying the filtration process in industrial production.

3.Sediment removal:

For sediment removal in liquid products (e.g., beverages, condiments), Papain decomposes insoluble protein aggregates and suspended particles. It prevents sediment formation during storage, optimizes product quality and consumer experience, and works efficiently under mild processing conditions.

1.Thermal Stability: Papain is stable at temperatures below 70 °C. Its enzymatic activity reaches optimal levels within the range of 40–60 °C, allowing efficient protein hydrolysis under typical processing conditions.

2.pH Stability: Papain remains effective over a broad pH range of 3.0–9.5. The enzyme exhibits optimal activity in a near-neutral environment, with a preferred pH of 6.0–7.0, making it suitable for various food and beverage applications.

3.Natural Source: Papain is a natural enzyme preparation obtained from the unripe fruit pulp of papaya through biotechnological extraction.

Q1：What fruit has the most papain?
A1:1.Unripe papaya: Contains the highest concentration of active papain in both the pulp and the latex (the milky sap).

2.Papaya latex: The latex collected from cuts in the green fruit is especially rich in papain and is commonly used for industrial extraction.

3.Ripe papaya: Contains much less active papain because the enzyme decreases as the fruit ripens.

Q2: How does papain clarify beer?
A2: Papain clarifies beer by hydrolyzing haze-forming proteins, which would otherwise bind with polyphenols and cause turbidity, especially at low temperatures. By breaking these proteins into smaller peptides and amino acids, papain prevents cloudiness, accelerates filtration, and helps maintain foam stability without affecting the beer's taste. It is typically added during brewing or after fermentation in controlled amounts to achieve optimal clarity.

Q3: Which is better, papain or bromelain?
A3: Papain and bromelain are both proteolytic enzymes, but their suitability depends on the application. Papain is preferred for beverage and beer clarification due to mild taste and effective protein hydrolysis, while bromelain is often used for meat tenderizing and nutraceuticals because it works well on animal proteins and tolerates higher temperatures.
