Enhancing Garlic Freshness in International Logistics: The Role of Temperature and Humidity Control

How Temperature and Humidity Control Ensures Fresh Garlic Quality in International Logistics

When exporting fresh garlic to global markets, maintaining quality from harvest to the final buyer is a complex challenge. Long-distance transportation often leads to issues such as sprouting, mold growth, and loss of aroma — all of which can damage brand reputation and reduce profit margins.

The Core Solution: Precision Climate Management

Modern cold chain logistics now rely on real-time temperature and humidity monitoring systems installed in refrigerated containers and trucks. According to industry standards, the optimal storage range for fresh garlic is between 0–4°C with relative humidity maintained at 75–85%. Deviations outside this window significantly increase spoilage risks:

• Temperatures above 4°C accelerate metabolic activity, leading to premature sprouting.
• Humidity below 75% causes dehydration and shriveling.
• Fluctuations over 10% RH promote fungal development — especially critical for long-haul shipments across different climates.

From Field to Fork: A Science-Backed Cold Chain Process

Successful export requires more than just cooling — it demands a full-system approach:

1. Post-harvest handling: Rapid pre-cooling within 2 hours post-harvest prevents heat buildup.
2. Packaging optimization: Use breathable polyethylene films that regulate moisture while preventing condensation inside crates.
3. Transportation integrity: Continuous data logging via IoT-enabled sensors ensures compliance throughout transit.

Our clients report up to 98% product integrity retention when these steps are followed consistently — far exceeding average industry performance (typically 75–85%).

Compliance = Credibility in Global Markets

For entry into EU, North America, or Gulf countries, adherence to certifications like GlobalG.A.P. and HACCP isn’t optional — it’s mandatory. These frameworks require documented proof of temperature control throughout the supply chain. We work closely with third-party auditors to ensure every shipment meets or exceeds these benchmarks.

In one case study, an exporter in Shandong Province reduced rejected consignments by 60% after implementing our integrated monitoring system — validated by an SGS report confirming consistent compliance with ISO 22000 standards.
