Food Grade Protease – High Activity & High Stability Solid Enzyme Preparation for Enzymatic Dehairing

Food Grade Protease is a high-efficiency enzymatic depilatory preparation developed for food processing applications. It is specially designed for dehairing processes and provides fast, controlled, and environmentally responsible hair removal under mild reaction conditions.

This product belongs to the category of food-grade solid enzyme additives. It appears as a milky white to light yellow powder and is formulated with protease and edible salt to ensure stable performance, easy handling, and consistent industrial application.

The enzyme preparation is primarily used in food processing (dehairing applications). Compared with traditional sulfide-based chemical dehairing methods, enzymatic treatment significantly reduces environmental pollution, minimizes wastewater burden, and helps maintain better substrate quality.

Преимущества продукта

Limitations of Sulfide Dehairing:
In conventional processing, sodium sulfide is commonly used to break disulfide bonds in keratin to achieve dehairing. However, this process generates large amounts of wastewater pollution and may negatively affect product quality.

Advantages of Enzymatic Dehairing:
This protease preparation selectively opens disulfide bonds in keratin and gently hydrolyzes elastic fiber structures. The process is milder, reduces environmental impact, and preserves substrate integrity. Increasing dosage and extending processing time enhance dehairing performance, while excessive dosage or elevated temperature may cause surface damage.

Метод применения

1. Soak raw materials until fully rehydrated and washed. Place into a rotating drum and add water at a ratio of raw material to water of 1:1.
2. Add 0.5% enzyme preparation (based on raw material weight) and mix evenly. Adjust pH to approximately 7.0 and maintain temperature around 35°C.
3. Start rotation and observe the dehairing process for approximately 4 hours, until hair removal is complete.

Raw material diversity, source variations, and local production environments may influence dehairing results. It is strongly recommended to conduct small-scale trials before proceeding to large-scale production. This helps avoid potential losses caused by differences in raw materials or processing conditions. Especially for lower-quality leather, it is even more important to precisely control the processing steps and treatment time.

Механизм действия

This protease preparation acts on keratin structures by selectively breaking disulfide bonds and gently degrading structural proteins responsible for hair attachment. The enzymatic reaction weakens the hair root structure, allowing efficient removal without aggressive chemical attack. The process operates effectively within a broad pH range of 6.0–12.0 and a temperature range of 20°C–60°C, with optimal performance observed at 30°C–40°C and pH 6.0–8.0.

Application Field

Widely used in food processing industries requiring enzymatic dehairing treatment and other related processing fields.
