Blockchain Traceability for Onions: From Farm to Market

Abstract

This solution overview introduces FoodTraze’s blockchain-based traceability solution for onions. It emphasizes the importance of maintaining freshness, preventing spoilage, and ensuring quality and origin verification throughout the supply chain. With transparent data sharing, stakeholders can monitor the entire journey of onions from cultivation to consumption.

Introduction

Onions are one of the most widely used vegetables in global kitchens. However, fluctuations in quality, improper storage, and lack of visibility in the supply chain can lead to wastage and price volatility. FoodTraze tackles these challenges by implementing blockchain-based traceability, allowing every transaction and process—from planting to delivery—to be securely recorded and verified. This ensures accountability among farmers, traders, and retailers, and helps consumers gain confidence in the quality and source of their onions.

Implementation

Critical Tracking Events (CTEs):

Cultivation: Farmers record seed variety, soil type, irrigation, pesticide usage, and harvesting date to maintain production transparency.
Sorting & Grading: Data on size, color, and quality grading are captured to standardize the product and ensure consistent quality.
Storage & Packaging: Information on storage temperature, humidity, batch codes, and packaging details is logged to prevent spoilage.
Distribution: Transport data, including temperature, route, and handling, is monitored to maintain freshness during transit.
Key Data Elements (KDEs):
Farm Information: Farmer details, certifications, and field locations for traceable origin data.
Quality Parameters: Moisture levels, size grading, and disease inspection results.
Batch & Storage Records: Harvest dates, lot numbers, and warehouse details.
Logistics Tracking: Delivery route, transport conditions, and distributor details.

Consumer Access:

By scanning a QR code on packaging or point-of-sale labels, consumers can view detailed information about the onion’s source, farming practices, storage, and transportation conditions. This transparency strengthens brand credibility and consumer trust.

Conclusion

With FoodTraze, onion traceability becomes seamless, transparent, and reliable. Farmers gain recognition for quality produce, distributors ensure proper handling, and consumers receive verified information about their food’s journey. Every onion—from field to kitchen—is accounted for, ensuring freshness, safety, and traceability powered by blockchain.
