Production Process
01
Raw Material Selection & Cleaning
High-quality apples are strictly selected and thoroughly cleaned to ensure raw material safety.
02
Crushing & Pressing in Anaerobic Environment
Apples are crushed and pressed under oxygen-limited conditions to minimize oxidative browning and preserve natural color and flavor.
03
Enzymatic Hydrolysis & Ultrafiltration
The juice undergoes enzymatic treatment and ultrafiltration to completely remove pectin, starch, and unstable proteins, resulting in clear and highly stable juice.
04
Low-Temperature Concentration
Using low-temperature vacuum evaporation or advanced membrane concentration (e.g., nanofiltration), water is removed efficiently at much lower temperatures than traditional boiling. This preserves thermosensitive nutrients (e.g., vitamin C) and volatile flavor compounds.
05
Sterilization & Aseptic Packaging
The concentrate is instant-sterilized and aseptically filled into large sterile bags or drums, ensuring extended shelf life and ease of storage and transportation.
