Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

Journal of Raman Spectroscopy, Volume 57, Issue 9, Page 1565-1576, September 2026.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Smart detection of juice adulteration: An approach based on ion mobility spectrometry and machine learning

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7406-7415, September 2026.
Abstract BACKGROUND Fruit juice quality is regulated by European Union legislation; however, adulteration by adding cheaper alternatives, such as white grape juice, remains a prevalent issue. This practice constitutes economic fraud and poses health risks to consumers, including potential allergic reactions to the adulterant.

Chemometric‐Driven Spectral Fingerprinting for Non‐Destructive Quality Assessment of Mangoes

Phytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
Visible–NIR spectroscopy using a compact open‐source spectrophotometer successfully tracked mango ripening by capturing wavelength‐specific changes linked to acidity, sugars, pigments, and DA index, enabling accurate non‐destructive prediction of ripening stages during ambient storage.
