Frequently Asked Questions
Q
What are the key processes involved in blueberry juice concentrate production?
The production process includes raw material processing, crushing, juice extraction, clarification, concentration, sterilization, and filling. Among these, enzymatic hydrolysis, ultrafiltration, and low-temperature concentration are the most critical steps to ensure product quality and nutritional integrity.
Q
What material is used for the equipment that contacts the product?
All equipment parts that come into direct contact with materials are manufactured from food grade SUS304 stainless steel (austenitic chromium nickel stainless steel). This material is corrosion-resistant, easy to clean, and fully complies with international food safety standards.
Q
What makes this blueberry juice concentrate stand out from conventional products?
The concentrate is rich in anthocyanins and antioxidants that support eye protection and brain health. The use of ambient temperature concentration technology preserves thermosensitive components, while the overall process delivers low energy consumption, stable quality, and an extended shelf life.
Q
In which industries or products can blueberry juice concentrate be applied?
Blueberry juice concentrate is widely used in fruit juice beverages and health products. It serves as a natural flavoring agent and nutritional enhancer, making it suitable for functional drinks, dietary supplements, and various food processing applications.
Q
How are common quality issues such as turbidity, browning, and sedimentation addressed?
Advanced processing solutions are employed, including ultrafiltration clarification, nanofiltration concentration, sterile large tank storage, and dynamic membrane technology. These methods effectively prevent turbidity, browning, and sedimentation, ensuring a consistently high-quality final product.
Q
What are the key technical parameters of the production system?
The system delivers a juice yield of 60%–75%, a Brix value of 65°Bx ± 1°Bx, and a pH range of 2.6–3.6. The production capacity is highly scalable, ranging from 10 to 2,500 tons per day, making it suitable for both small-scale and large-scale industrial operations.

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.
