A complete guide to food logistics covering cold chain, warehousing, refrigerated transport, last-mile delivery, technology, and supply chain management from farm to fork.
What is Food Logistics?
Food logistics refers to the integrated planning, execution, and control of the movement and storage of food products from farms and food processing units to wholesalers, retailers, and finally consumers, under controlled conditions that preserve quality, safety, and shelf life.
It includes:
- Post-harvest handling
- Cold chain management
- Warehousing and inventory control
- Temperature-controlled transportation
- Packaging and distribution
- Quality and safety compliance
In modern agri-food systems, food logistics is not just transportation—it is a biological, engineering, and supply-chain management system.
Why Food Logistics is Critical in the Food Supply Chain
According to FAO estimates on global post-harvest food losses, nearly one-third of all food produced for human consumption is lost annually, with the highest losses occurring in perishable fruits, vegetables, meat, and dairy due to inadequate cold chain and logistics infrastructure.
Fruits, vegetables, meat, dairy, seafood, and ready-to-eat foods are highly perishable. Without proper logistics:
- Respiration and enzymatic activity continue
- Microbial growth accelerates
- Moisture loss causes wilting and weight loss
- Temperature abuse leads to rapid spoilage
- Economic losses increase across the value chain
Globally, 25–35% of food is lost post-harvest, and in developing economies this can exceed 40%, mainly due to poor logistics and cold chain gaps.
Stages of Food Logistics (Farm to Fork)
- Harvesting & Collection
- Pre-Cooling & Primary Processing
- Packhouse Operations
- Cold Storage & Controlled Atmosphere Storage
- Refrigerated Transportation (Reefer Logistics)
- Distribution Centers & Dark Stores
- Retail / Quick Commerce Fulfilment
- Last-Mile Delivery to Consumers
The concept of cold chain definition and farm-to-fork temperature control emphasizes uninterrupted refrigeration and humidity management from harvest through processing, storage, transportation, and retail.
Each stage requires precise control of temperature, relative humidity, atmosphere, and handling practices.
What is Cold Chain Logistics?
Cold chain logistics is the temperature-controlled segment of food logistics that maintains products within their optimal thermal and humidity ranges from harvest to consumption.
Key components:
- Pre-cooling systems
- Cold storage (chillers, freezers, CA rooms)
- Reefer trucks and containers
- Insulated packaging
- Temperature and RH monitoring sensors
- Backup power and energy management
Scientific research on temperature-controlled supply chain systems shows that even short-term thermal abuse accelerates respiration, microbial growth, and enzymatic degradation in perishable foods.
Optimal Temperature and Relative Humidity for Major Foods
| Commodity | Temperature (°C) | Relative Humidity (%) | Storage Life |
|---|---|---|---|
| Apple | 0–1 | 90–95 | 2–6 months |
| Banana | 13–14 | 85–90 | 2–4 weeks |
| Tomato | 12–13 | 85–90 | 2–3 weeks |
| Grape | 0–1 | 90–95 | 1–3 months |
| Leafy Greens | 0–1 | 95–98 | 1–3 weeks |
| Meat (Chilled) | 0–2 | 85–90 | 1–3 weeks |
| Frozen Foods | −18 | 90–95 | 6–12 months |
Role of Warehousing in Food Logistics
Modern food warehouses are biological preservation facilities, not just storage buildings. FAO technical guidelines on controlled atmosphere storage principles confirm that oxygen, carbon dioxide, temperature, and relative humidity control can extend shelf life of fruits and vegetables by several months.
Functions:
- Temperature and humidity control
- Ripening chambers
- Controlled atmosphere storage
- Sorting, grading, and packaging
- Inventory rotation (FIFO / FEFO)
- Quality inspection and traceability
Green Warehousing
Sustainable food logistics now integrates:
- Rooftop solar PV systems
- Energy-efficient refrigeration
- Thermal insulation and PCM panels
- Rainwater harvesting
- EV charging infrastructure
Studies on solar-powered cold storage economics demonstrate that rooftop photovoltaic systems can reduce refrigeration energy costs by 40–70% while improving operational resilience.
A 100,000 sq.ft. solar-roof warehouse can:
- Power cold rooms and sorting lines
- Support EV last-mile fleets
- Reduce carbon footprint
- Lower operating costs significantly
Transportation of Perishable Foods
According to ASHRAE refrigeration standards on refrigerated transport requirements for perishable foods, precise control of air temperature, relative humidity, and air velocity is essential to prevent moisture loss and chilling injury.
Refrigerated Transport (Reefer Logistics)
Includes:
- Reefer trucks
- Reefer containers
- Insulated vans
- Multimodal cold chain (road, rail, sea, air)
Key requirements:
- Stable temperature
- High relative humidity (85–95%)
- Shock and vibration control
- Continuous monitoring and data logging
EV Two-Wheelers in Last-Mile Food Delivery
In quick commerce and hyperlocal logistics:
- EV two-wheelers dominate short routes
- Lower operating cost
- High delivery frequency
- Zero tailpipe emissions
- Integrated with dark stores and micro-fulfilment centers
Post-Harvest Losses and Logistics Gaps
The World Bank cold chain infrastructure gaps in developing countries report identifies lack of pre-cooling, insufficient cold storage capacity, and weak reefer connectivity as primary drivers of 30–40% horticultural losses.
Major causes:
- Lack of pre-cooling
- Poor cold storage distribution
- Inadequate reefer transport
- Road infrastructure bottlenecks
- Power supply instability
- Improper packaging
- Temperature and RH fluctuations
Losses translate into:
- Reduced farmer income
- Higher consumer prices
- Lower export competitiveness
- Food security risks
Technologies Used in Modern Food Logistics
Recent studies on IoT-based temperature and humidity monitoring in cold chains show that real-time sensor networks significantly reduce temperature excursions and spoilage risk.
- IoT Sensors – Real-time temperature and RH monitoring
- Blockchain – Traceability and food safety compliance
- Warehouse Automation – Conveyors, AS/RS, robotic picking
- AI Demand Forecasting – Inventory optimization
