Jialecheng Foods, founded in 1989 in Taishan City, Guangdong Province, is one of China’s leading producers of winter melon paste and sweet pastry fillings. With decades of experience, the company has refined its production system to combine traditional cooking craftsmanship with modern industrial control — ensuring that every batch of filling maintains the same taste, texture, and safety standards.

Consistency is the key to success for bakery manufacturers who rely on uniform quality across thousands of pastries. Below is a detailed look at how Jialecheng Foods achieves that through its integrated production process, ingredient control, and technology-driven quality management.

1. Farm-to-Factory Raw Material Control

Jialecheng operates its own winter melon cultivation bases under a “company + farmer” cooperation model. This system gives the company full traceability and control over its raw materials.

Quality assurance begins at the farm:

• Strict seed selection: Only high-yield, low-fiber melon varieties are cultivated.

• Standardized planting techniques: Farmers follow guidelines for soil, irrigation, and fertilizer use.

• Harvest at optimal maturity: Melons are picked at the right sugar and water ratio for best paste yield.

• On-site inspection: Every batch of melon is checked for appearance, texture, and freshness before processing.

This vertical integration ensures that only the freshest, uniform melons enter the production line — the first step in consistent filling quality.

2. Standardized Ingredient Formulation

Winter melon alone cannot guarantee consistency; precise ingredient ratios are equally important. Jialecheng follows fixed formulations based on years of R&D testing.

Typical composition control:

• Winter melon: 55–60%

• Sugar: 30–35%

• Maltose or glucose syrup: 5–10%

• Vegetable oil or shortening: 3–5%

All ingredients are weighed using digital load-cell scales to eliminate human error. Each recipe is stored in the company’s production management system (PMS), ensuring that operators follow exact specifications for sweetness, viscosity, and color.

3. Controlled Cooking and Concentration Process

The cooking stage is where texture and gloss are defined — and Jialecheng uses automated vacuum cooking systems to guarantee uniform results.

Key technologies used:

• Steam-jacketed vacuum cookers: Maintain consistent temperature (95–105°C) while preventing caramel burn.

• Agitation control: Automatic paddles stir at fixed speed to avoid overcooking or uneven caramelization.

• Digital sensors: Continuously monitor moisture evaporation and viscosity.

• Batch recording: Each production run is logged with time, temperature, and sugar concentration data.

This ensures every batch reaches the same moisture content (18–22%) and Brix level, resulting in uniform density and sheen.

4. In-Line Quality Testing

Throughout production, Jialecheng performs in-line and post-batch quality inspections to maintain precision.

Tests include:

• Moisture content (by infrared analyzer)

• Viscosity and texture (using rotational rheometer)

• Color uniformity (via colorimeter)

• Microbiological checks (for hygiene and safety)

Each test result is stored in the company’s digital traceability database, linked to batch numbers for complete product tracking.

5. Hygiene and Safety Systems

Jialecheng maintains ISO9001, HACCP, and food safety certification, which require rigorous monitoring at every stage:

• Stainless steel production lines to avoid contamination.

• Filtered water systems for washing and cooking.

• Closed-loop piping to prevent air or particle exposure.

• Regular disinfection and environmental checks in processing zones.

Workers follow Good Manufacturing Practice (GMP) protocols — including clothing sanitization, temperature checks, and hand hygiene — to ensure clean and safe production.

6. Automated Packaging and Vacuum Sealing

After cooking and cooling, the paste is transferred through sealed pipelines to automatic weighing and vacuum packaging machines.

• Each pack is sealed under low-oxygen conditions to preserve color and freshness.

• Metal detectors and optical scanners inspect all packages before boxing.

• The sealed paste maintains its texture and aroma for 6–12 months under proper storage.

7. Continuous R&D and Product Customization

To maintain consistency across markets, Jialecheng’s R&D team regularly adjusts product parameters based on customer requirements:

• Sugar and moisture levels tailored for tropical or cold climates.

• Flavor customization (coconut, sesame, pineapple, mango).

• Low-sugar or fiber-enriched versions for health-oriented bakery lines.

Every new formula undergoes pilot-scale testing and stability trials before mass production, ensuring reliable performance for OEM and ODM clients.

8. Quality Traceability and After-Sales Support

Each production batch carries a unique traceability code that links:

• Raw material origin

• Production date and operator

• Testing records

• Shipment details

This system allows customers to verify quality data instantly and provides full accountability in case of inquiries. Jialecheng’s technical team also offers baking guidance and formulation adjustment to help clients maintain consistent results in their own pastry production lines.
