Strawberry Pulp Juice Processing Technology: From Raw Fruit to High-Quality Beverage Production

 

With the growing demand for natural, flavorful, and texture-rich fruit beverages, strawberry pulp juice has become one of the fastest-growing categories in the global fruit processing industry. Compared with clarified juice, strawberry juice with pulp delivers a richer mouthfeel, enhanced sensory experience, and higher perceived natural value, making it highly attractive in both retail and foodservice sectors.

According to market data, the global strawberry juice market reached approximately RMB 20.19 billion in 2024, and is projected to grow to RMB 30.86 billion by 2031. In China alone, the strawberry juice beverage market hit RMB 18.56 billion in 2025, with a strong year-on-year growth rate of 14.3%, significantly outperforming the broader beverage industry.

For manufacturers and brand owners, mastering the processing technology of strawberry pulp juice is key to achieving product differentiation and consistent quality.

 

 

 

A standard formulation for strawberry pulp juice includes:

• Strawberry puree / juice: ≥50%
• White sugar: ~6%
• High-intensity sweetener (e.g., protein sugar FT-50): 0.1%
• Agar: 0.1%
• Carboxymethyl cellulose (CMC): 0.2%

This formulation ensures a balanced sweetness, viscosity, and stability, while maintaining the natural flavor of strawberries.

 

 

 

To achieve industrial-scale production, the following equipment is typically required:

• Pulping and seed separation machine
• Colloid mill
• High-pressure homogenizer
• Vacuum degassing system
• UHT sterilization unit
• Aseptic filling machine

Each step plays a critical role in ensuring product consistency, microbial safety, and shelf stability.

 

 

 

The standard production process is as follows:

Raw Material → Washing → Stem Removal → Pulping → Colloid Milling → Formulation → Degassing → Homogenization → Sterilization → Filling → Cooling → Inspection → Final Product

 

 

 

(1) Pulping and Seed Removal

A cooled extraction method is recommended. Using a pulping and separation machine with a 0.5–0.8 mm mesh, strawberry seeds are removed efficiently. During pulping, 10–15% water is added to improve pulp separation and processing efficiency.

(2) Colloid Milling

The seed-free pulp is processed through a colloid mill to achieve fine particle size reduction, improving mouthfeel and suspension stability.

(3) Formulation

Sugar is dissolved in water and heated to form syrup. Stabilizers, sweeteners, and acidulants are pre-dissolved and added sequentially. Proper mixing ensures uniform distribution and consistent taste.

(4) Degassing and Homogenization

Vacuum degassing is performed at 90.6–93.3 kPa, removing dissolved oxygen and preventing oxidation.

Two-stage homogenization is applied:

• First stage: 16.4 MPa
• Second stage: 11.8 MPa
• Temperature: ~60°C

This step is critical for achieving stable suspension and smooth texture.

(5) Sterilization and Filling

Ultra-high temperature (UHT) sterilization is conducted at 121°C for 5–10 seconds, followed by aseptic filling. This ensures product safety while preserving flavor and nutrients.

 

 

 

Sensory Properties

• Color: Bright red, uniform
• Taste: Sweet and sour, no off-flavor
• Aroma: Natural strawberry fragrance
• Texture: Uniformly turbid, smooth, no large particles

Physicochemical Indicators

• Soluble solids: 10–12%
• Organic acid: ~0.4%
• Fruit juice content: ≥50%

 

 

 

Strawberry pulp juice represents a clear trend toward premium, texture-enhanced beverages. For B2B buyers and beverage brands, opportunities lie in:

• Developing clean-label formulations
• Using natural fruit powders or extracts to enhance flavor and color
• Improving processing efficiency and yield
• Creating differentiated products such as functional or fortified fruit beverages

As consumer preference continues shifting toward natural, minimally processed, and sensory-rich drinks, mastering pulp juice processing technology will be essential for staying competitive in the global market.
