MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202411093846 A) filed by Agnext Technologies Private Limited on November 29, 2024, for System And Method For Real-Time Detection Of Adulteration In Powdered Food Material Using Near- Infrared Spectroscopy.
Inventors include Subrat Kumar Panda; Biswajit Manna; Dorothy Kingsley; and Akash Bhardwaj.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present disclosure provides a system and method for real-time detection of adulteration in a powdered food material using an artificial intelligence and near- infrared spectroscopy. The system includes a spectroscopy unit for acquiring spectral data, an AI-powered processing unit for preprocessing, feature extraction, adulteration classification, and purity index computation, a reference spectral database, and a user interface for real-time display. The AI-powered processing unit compares sample spectra with authenticated reference fingerprints using similarity or distance metrics to determine purity and classify samples as pure or adulterated. The method includes capturing NIR spectra from the powdered material, preprocessing the spectra, performing dimensionality reduction, identifying adulterants through trained machine learning models, and generating a purity index. The purity index is further mapped to a dynamic quality-pricing evaluation module that assigns quality grades or price recommendations. The disclosure enables rapid, non-destructive, on-site assessment across the supply chain. FIG. 1
