Breakthrough in Food Quality Assessment
Researchers have developed a smartphone-based artificial intelligence system that reportedly predicts the ripeness and internal quality of avocados with high accuracy, according to a new study published in Current Research in Food Science. The technology addresses what sources indicate is a significant global food waste problem, particularly for avocados, which are among the most wasted fruits worldwide due to overripeness.
Research Methodology and Accuracy Rates
The research team from Oregon State University and Florida State University trained AI models using more than 1,400 iPhone images of Hass avocados, the report states. The system achieved nearly 92% accuracy in predicting firmness, a key indicator of ripeness, and over 84% accuracy in determining internal quality (fresh versus rotten).
“To overcome limitations of previous approaches, we used deep learning methods that automatically capture a broader range of information, including shape, texture, and spatial patterns to enhance the accuracy and robustness of avocado quality predictions,” said In-Hwan Lee, a doctoral student involved in the project, according to the published research available through Elsevier’s publishing platform.
Addressing Global Food Waste Challenge
The research addresses what analysts suggest is a major global challenge: food waste. Approximately 30% of the world’s food production is wasted, with fruits like avocados being particularly vulnerable due to their delicate ripening process. The technology development aligns with the U.S. Department of Agriculture and Environmental Protection Agency’s national goal to reduce food waste by 50% by 2030.
“Avocados are among the most wasted fruits globally due to overripeness,” said Luyao Ma, an assistant professor at Oregon State University, according to the study. “Our goal was to create a tool that helps consumers and retailers make smarter decisions about when to use or sell avocados.”
Potential Applications and Future Development
The researchers believe the technology has multiple potential applications:
- Consumer use: Sources indicate consumers could eventually use the technology at home to determine the optimal time to eat an avocado
- Retail optimization: Retailers could use the system to determine which avocados should be sold first based on ripeness
- Supply chain management: Processing facilities could better sort and grade fruit, shipping riper batches to nearby retailers
- Broader applications: The technology reportedly has potential to assess ripeness and quality of other types of food
Context and Industry Developments
This food technology innovation emerges alongside other significant industry developments, including BlackRock’s reported partnership with NVIDIA and Microsoft in technology investments, Indonesia’s economic growth targets, and various regulatory developments affecting technology sectors according to recent reports.
The research team notes that accuracy rates could improve as more images are added to the model. “Avocados are just the beginning,” Ma stated in the research publication. “This technology could be applied much more broadly, helping consumers, retailers, and distributors make smarter decisions and reduce waste.”
As food waste reduction becomes increasingly prioritized globally, researchers suggest such technological innovations could play a significant role in creating more efficient food systems and reducing environmental impact.
