What is it about?

Food quality preservation and waste reduction depend on effective storage management in refrigerators. The application of RESnet method, a deep learning technique, for refrigerator storage optimization through classification of Fruits and Vegetables (FVs) to suggest the best storage conditions according to their classification. A novel dataset was created consisting of 3450 images of five types of FVs (Cucumber, Grapefruit, Strawberry, Tomato, and Turnip), where each type contains two subcategories (fresh and damaged). The RESnet model is trained on a dataset containing many FVs which are generally stored in refrigerators. Preprocessing of the FVs images, training of the RESnet model using a deep convolutional neural network architecture, and assessment of its performance in terms of classification accuracy are the components of the methodology. By means of comprehensive experimentation and verification, achieved by our research a quite high 99% accuracy rate in classification of FVs for refrigerator storage. The results prove that RESnet is efficient in precisely identifying and classifying FVs which helps users to sort their fridge in a proper way. Consumers can achieve the effects of optimizing storage conditions, extending shelf life, and reducing food spoilage through this technology. This study is not limited to household applications but also has implication for commercial setting such as grocery stores, restaurants and food distribution centers. Automation of FVs classification with RESnet architecture will simplify the inventory management activities, reduce the wastage and improve the overall performance of the operations. In a nutshell, RESnet integration for the optimization of refrigerators is a very encouraging approach that will aid in improving the storage efficiency as well as reduce food wastage. Further research directions could focus on scale, a real-time implementation and integration with smart refrigerator technologies for higher practicality and impact of this approach.

Why is it important?

The paper "Refrigerator Optimization: Leveraging RESnet Method for Enhanced Storage Efficiency" presents an AI-driven approach to reducing food waste by optimizing refrigerator storage using deep learning. By employing the ResNet model, the study achieves 99% accuracy in classifying fruits and vegetables into fresh and damaged categories, aiding in better organization and storage management. The research introduces a novel dataset of 3,450 images with diverse backgrounds, enhancing model robustness. Its findings have practical implications not only for household refrigerators but also for grocery stores, restaurants, and food distribution centers, improving inventory management and reducing spoilage. Additionally, the study lays the groundwork for future integration with smart IoT-enabled refrigeration systems, offering a promising direction for AI-powered food preservation and sustainability.

Perspectives

The findings of "Refrigerator Optimization: Leveraging RESnet Method for Enhanced Storage Efficiency" open several promising research and application directions. Future studies could explore real-time implementation by integrating the ResNet-based classification system with IoT-enabled smart refrigerators, allowing automated monitoring and predictive food management. Additionally, expanding the dataset with more food categories and environmental conditions (e.g., humidity, temperature variations) could enhance model generalization. Another avenue is energy-efficient AI models, where lightweight deep learning architectures can be optimized for deployment in edge devices. Commercial applications in supply chain management, supermarkets, and food distribution centers could further benefit from this technology, improving food quality tracking and reducing waste. Moreover, interdisciplinary research combining AI, food science, and sustainability policies could foster smarter food storage ecosystems, contributing to global efforts in food security and resource conservation.
