Fermentation Process

Perilla leaves, a seemingly simple natural ingredient, have become the heart of Lá Mây’s household cleaning products thanks to a scientific and sustainable fermentation process. This is the journey from nature to technology, transforming lush green leaves into an effective, eco-friendly cleaning agent in every product.

To turn these humble leaves into a powerful cleaning component, we have developed a meticulous and advanced fermentation process. Each step is carefully executed to preserve the precious nutrients from nature while maximizing cleaning efficiency. This journey begins with selecting the freshest, highest-quality materials and sets the stage for a fully enclosed production cycle that surpasses conventional technologies in quality and sustainability.

PERILLA LEAF FERMENTATION PROCESS

The Essence of Nature - The Innovation of Science

1. Harvesting and Selecting Perilla Leaves

The journey begins in clean farming areas, where perilla leaves are cultivated without harmful chemicals or pesticides. Each leaf is meticulously selected to ensure freshness and retain its natural nutrient content. Harvesting is carried out at the optimal stage of leaf development, when natural compounds such as polyphenols and flavonoids are at their peak.

2. Cleaning and Preparing Ingredients

After harvesting, perilla leaves are carefully washed with water to remove dirt and impurities. This process ensures the leaves are clean while preserving all their natural nutrients. The leaves are then finely chopped and lightly processed to prepare for the fermentation stage.

3. Establishing a High-Tech Fermentation Environment

Once the perilla leaves are thoroughly cleaned, they are transferred into a closed fermentation system utilizing advanced technology to comprehensively control environmental factors. This is a critical stage that determines the quality of the fermented solution and its effectiveness in household cleaning products.

The fermentation environment is precisely controlled

The fermentation tanks are made from specialized stainless steel, ensuring they are corrosion-resistant and non-reactive with natural ingredients. The system is programmed to monitor and regulate temperature, humidity, and oxygen concentration throughout the fermentation process, maintaining optimal conditions for beneficial microorganisms. The temperature is consistently maintained between 30–37°C, the ideal range for lactic bacteria and enzymes to function at their best.

Eliminating the Risk of Cross-Contamination

To ensure purity and prevent harmful bacteria or impurities from entering, the entire system operates under sterile conditions. All materials and equipment that come into contact with the perilla leaves are meticulously sterilized using high-pressure steam before use. Furthermore, the pumps and lids of the fermentation tanks are designed to be completely sealed, allowing only necessary gases to pass through sterile filters.

Utilizing Smart Sensors and Monitoring Systems

The fermentation tanks are made from specialized stainless steel, ensuring they are resistant to corrosion and non-reactive with natural ingredients. The system is programmed to monitor and control temperature, humidity, and oxygen levels throughout the fermentation process, maintaining optimal conditions for the activity of beneficial microorganisms.

The temperature is kept within the range of 30–37°C, the ideal range for lactic bacteria and enzymes to perform at their peak efficiency.

Activating Beneficial Microorganisms with Gentle Microwave Technology

A unique innovation in Lá Mây’s process is the use of gentle microwave technology to activate beneficial microorganisms before fermentation. This technology accelerates the growth of lactic bacteria and optimizes enzyme production without compromising the natural nutrients in perilla leaves.

Clean Air Circulation and Storage System

To ensure fermentation quality, the system is equipped with clean air circulation technology to maintain stable oxygen levels within the tanks. CO2 produced during the fermentation process is expelled through specialized filter valves, preventing pressure build-up that could disrupt the metabolic process.

Thanks to the application of modern technology and a closed-loop process, Lá Mây ensures that every stage of the fermentation process achieves optimal efficiency, preserving the purity and cleaning potential of perilla leaves. The result is a fermented ingredient that is not only exceptionally effective but also absolutely safe, meeting the highest standards for household cleaning products.

4. Natural Fermentation Process

During this stage, microorganisms work vigorously to break down large compounds in perilla leaves into smaller molecules such as enzymes, organic acids, and natural surfactants. These substances provide effective cleaning power, odor elimination, antibacterial properties, and stain removal without the need for harsh chemicals.

5. Control and Optimization

The fermentation process is a delicate balancing act. If it proceeds too quickly, microorganisms may not fully convert all nutrients. If too slow, the raw materials might lose their freshness. Lá Mây has conducted thorough research to determine the optimal fermentation time, ensuring the nutrients achieve maximum effectiveness while retaining their natural properties.

6. Fermentation Filtration in the Final Product

The recovery and separation of fermentation residues are critical steps to ensure the final solution is stable and does not continue fermenting during storage and use. Lá Mây employs advanced technology to eliminate or neutralize all environments conducive to microbial activity in the product. Additionally, all residual live microorganisms are completely removed, maintaining the product's quality and safety over time.

Ultrafiltration Technology

Low-Temperature Pasteurization

After the fermentation process is complete, the solution is passed through an ultra-fine filtration system. This technology utilizes membranes with extremely small pore sizes (ranging from 0.01 to 0.1 micrometers) to remove microorganisms, including live bacteria and yeast. The membrane not only captures microbial cells but also eliminates impurities and tiny residues from the perilla leaves, ensuring the resulting solution is pure and uniform.

UV Sterilization Technology

To enhance safety, the solution, after filtration and pasteurization, may undergo UV treatment. This technology uses ultraviolet light wavelengths to destroy the DNA of any remaining bacteria or microorganisms, ensuring the product is completely fermentation-free after packaging.

After filtration, the solution is sterilized using a low-temperature pasteurization method, heating it to 60–70°C for a short period. This process effectively eliminates all live microorganisms without deactivating the enzymes and natural nutrients in the fermented solution. By precisely controlling the temperature, we ensure that the solution retains its optimal cleaning and antibacterial properties.

Packaging in a Sterile Environment

After treatment, the solution is immediately transferred to a closed packaging process in a sterile environment to prevent recontamination. All packaging materials and equipment that come into contact with the product are pre-sterilized using steam or UV light. As a result, the final packaged product remains stable, free from live microorganisms, and does not continue the fermentation process.

7. Strict Quality Control

Each batch of products containing fermented ingredients undergoes thorough testing to ensure consistent quality. These tests include evaluating cleaning efficiency, antibacterial properties, and safety for users’ health and the environment.

The perilla leaf fermentation process at Lá Mây is not only a perfect combination of science and nature but also a testament to our commitment to quality and environmental responsibility. Every product is the result of a closed-loop process, from pristine green leaves to pure fermented solutions, delivering superior cleaning performance and absolute safety. With Lá Mây, every step of cleaning goes beyond caring for your home—it contributes to protecting a sustainable green environment for the future.
