FoodSafe Scanner

FoodSafe Scanner is a Flask-based web application that allows users to scan food product barcodes and receive detailed information about the product, including a list of ingredients and their potential health risks. It uses the Open Food Facts API to fetch product data and compares ingredients against a predefined list of risky ingredients.

Features

• Scan Barcode: Scan a product's barcode to retrieve basic information about the product.
• Analyze Ingredients: Analyze the ingredients of the product against a predefined list of risky ingredients and receive detailed health risk information.
• Risk Assessment: The application identifies ingredients that could pose health risks (e.g., carcinogens, allergens, and other harmful substances).

Prerequisites

• Python 3.x
• pip (Python package manager)

Installation

1. Clone the repository:

   git clone https://github.com/MicheleGiammarini/FoodSafe-Scanner.git
   cd FoodSafe-Scanner

2. Create a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

3. Install the required dependencies:

   pip install -r requirements.txt

4. Run the Flask application:

   python main.py

   The server will start and listen on http://0.0.0.0:5000.
