Detailed Production Workflow

Phase 1: Scientific Cultivation

Controlled Environment:
Grown in pH 4.5-5.5 volcanic soil under 1,800+ annual sunshine hours
Drip irrigation system with real-time nutrient monitoring

Harvest Protocol:
Hand-picked at peak ripeness (7-10 days post-color change)
6-hour maximum field-to-cooling time

Phase 2: Precision Processing

Hydro Cooling
Rapidly reduce field heat to 4°C within 90 minutes using 2°C chilled water

Four-Stage Cleaning

Primary rinse: High-pressure air knife removal of debris

Secondary wash: Ozonated water (2.0ppm) sanitation

Tertiary bath: Food-grade citric acid solution (pH 3.5)

Final spray: Reverse osmosis water mist

Optical Sorting

Near-infrared spectroscopy detects sugar content

360° camera array identifies surface defects

Compressed air ejection removes substandard berries

IQF Freezing

Pre-chilling: Stepwise cooling from 10°C→0°C→-15°C

Core freezing: -45°C liquid nitrogen immersion for 110 seconds

Post-freeze treatment: Anti-caking agent application (optional)

Packaging

Nitrogen-flushed packaging with <1% oxygen residue

Triple-layer moisture barrier film
