Fresh Eucommia leaves are rich in precious ingredients such as chlorogenic acid, flavonoids, and aucubin, but these active substances are easily affected by the external environment. In order to ensure the stability of the active ingredients during processing, fresh leaf pretreatment becomes the most critical link in Eucommia production. The four-step pretreatment method, which has been verified by years of practice, can retain the active ingredients of Eucommia leaves to the maximum extent and ensure product quality.
The active ingredients in fresh Eucommia leaves are very sensitive to conditions such as oxygen, temperature, humidity and light. If handled improperly, these precious ingredients can easily degrade and become ineffective, directly affecting the efficacy of the final product. Therefore, how to maintain the activity of fresh leaves is the primary issue in Eucommia processing.
1. Scientific picking and transportation
Choose to pick in the early morning or evening, when the leaves have moderate moisture content and low temperature. They must be transported to the factory within 2 hours after picking, and 5-10℃ cold chain transportation is used throughout the process
2. Fine sorting
Use an intelligent sorting system to remove old leaves, diseased leaves and immature leaves, ensuring that every fresh leaf entering the processing link meets the standards
3. Low-temperature cleaning
Use 10-15℃ cold water for cleaning to effectively remove surface impurities and avoid high temperature from destroying active ingredients
4. Precision drying
Use 40-50℃ layered hot air drying technology to quickly remove moisture and ensure uniform drying
More complete ingredient retention: The retention rate of active ingredients such as chlorogenic acid and flavonoids is significantly improved. Low temperature treatment effectively prevents oxidative decomposition
Better product quality: maintain natural color and fresh taste, reduce bitter substances, and better palatability
Safer and more secure: significantly reduce pesticide residues and microbial contamination, inhibit bacterial and mold growth
Higher production efficiency: mechanized operation shortens processing time and reduces traditional drying losses
Strict quality control: full process quality monitoring ensures stable quality, blockchain technology is used to achieve full traceability, and environmentally friendly processes meet the requirements of sustainable development
This pretreatment process is the core technology to ensure the quality of Eucommia products. Through the scientific four-step treatment method, not only the active ingredients of Eucommia leaves are fully retained, but also a solid foundation is laid for subsequent processing. With the continuous improvement of the process, the Eucommia industry will surely bring more high-quality choices to the health product market.
