π½οΈ Extended Food-270 Dataset
This dataset is an extended version of the original Food-101 dataset, designed to improve the diversity and representativeness of food image classification models.
It combines the well-known Food-101 dataset with additional custom food images collected and curated by Berker Γveyik to expand the number of classes and enhance the datasetβs real-world applicability.
π Overview
- Base Dataset: Food-101
- Extended Version: Food-270
- Total Classes: 270 (101 original + 169 custom classes)
- Total Images: ~ 229.245
- Split: 80% training / 20% testing
- License: CC BY-NC 4.0
π§ Motivation
The original Food-101 dataset is a landmark benchmark for food recognition tasks, yet it primarily focuses on Western cuisine.
To enhance cultural and dietary diversity, this dataset extends Food-101 by adding 169 new food categories, including homemade, regional, and custom dishes.
These additional categories were carefully curated to:
- Improve the diversity and generalization capabilities of food classification models.
- Provide broader representation for non-Western and culturally specific foods.
- Enable research in nutrition tracking, food recognition, and calorie estimation applications.
This dataset is particularly suitable for:
- Food classification and computer vision research.
- Nutrition estimation and smart diet-tracking systems.
- AI-driven food recognition mobile applications.

- Train Folder: Contains 80% of the total images for training.
- Test Folder: Contains 20% of the total images for model evaluation.
- Each subfolder represents one distinct food class.
βοΈ Dataset Creation Process
Data Collection
- The base 101 food classes were sourced directly from the Food-101 dataset.
- 169 new classes were manually collected from diverse online sources and personal photography.
Data Cleaning and Curation
- Duplicate and low-quality images were removed.
- Labels were verified and organized consistently across classes.
- Class distributions were balanced as much as possible.
Train/Test Split
- The dataset was divided with an 80/20 ratio, ensuring that each class maintains the same proportion of samples in both sets.
π License and Usage
This dataset is distributed under the Creative Commons Attribution-NonCommercial 4.0 International License (CC BY-NC 4.0).
This means:
- β You may use, share, and adapt this dataset for non-commercial purposes.
- β You may not use this dataset for commercial purposes or redistribution for profit.
Why CC BY-NC 4.0?
The chosen license reflects the datasetβs educational and research-oriented purpose:
- To respect the original Food-101 creators and their open contribution.
- To encourage academic use and non-commercial AI development.
- To prevent misuse or unauthorized commercial exploitation.
