Blockchain Traceability for Tomatoes: From Farm to Fork

Abstract

This solution overview presents FoodTraze’s blockchain-based traceability system for tomatoes. It highlights the importance of ensuring freshness, reducing post-harvest losses, and maintaining safety and transparency across the supply chain—so consumers can trust the tomatoes they buy and eat.

Introduction

Tomatoes are one of the most consumed vegetables worldwide, yet challenges such as pesticide misuse, quality degradation, and post-harvest contamination often affect consumer trust and farmer incomes. FoodTraze solves this by implementing blockchain-powered traceability that records and secures every step—from tomato cultivation to retail shelves. This system ensures accountability, supports safe food handling, and helps consumers make informed choices.

Implementation

Critical Tracking Events (CTEs):

Cultivation: Farmers record details such as seed variety, sowing date, irrigation, pesticide usage, and harvesting practices.

Post-Harvest Handling: Sorting, grading, and quality testing (ripeness, pesticide residue levels) are documented.

Packaging & Storage: Packaging dates, batch codes, and storage conditions (temperature, humidity) are captured.

Distribution: Transportation conditions, handling practices, and delivery routes are tracked to maintain freshness.

Key Data Elements (KDEs):

Farm & Supplier Information: Data on growers, certifications (organic, GAP, sustainability).

Quality Metrics: Ripeness index, pesticide residue results, freshness indicators.

Batch Information: Harvest dates, grading results, and packaging identifiers.

Logistics Records: Temperature logs, transit duration, and distribution details.

Consumer Access:

Consumers can scan a QR code on packaging or at retail counters to access verified data on tomato origin, farming practices, handling, and quality checks. This transparency builds trust and promotes responsible consumption.

Conclusion

With FoodTraze, the tomato supply chain becomes transparent, efficient, and trustworthy. Farmers gain visibility for their sustainable practices, retailers can ensure product quality, and consumers enjoy safe, fresh, and traceable tomatoes—strengthening the entire farm-to-fork journey.
