Soaking Water Management Strategies for Enhanced Quality of Parboiled Rice

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Parboiling is a hydrothermal process that alters rice physicochemical and nutritional properties. The soaking step is crucial, influencing off‐flavor formation, mineral retention, and effluent quality. This study evaluated five soaking water (SW) management strategies combining different frequencies and volumes of SW ...

Micro‐QuEChERS Extraction for Broad‐Spectrum LC‐QQQ‐MS Quantification of Nitazene Analogs in Plasma: A Validated Method With Casework Application

open access: yesDrug Testing and Analysis, EarlyView.
Micro‐QuEChERS sample preparation coupled to LC‐QQQ‐MS enabled sensitive quantification of nitazene analogs in 100 μL of plasma. The validated method provided low detection limits and was successfully applied to an authentic intoxication case involving N‐pyrrolidino protonitazene, supporting clinical and forensic toxicology workflows.

Theory of Solid-Phase Microextraction [PDF]

open access: yesJournal of Chromatographic Science, 2000
The main objective of this contribution is to describe the fundamental concepts associated with solid-phase microextraction (SPME). Theory provides insight when developing SPME methods and identifies parameters for rigorous control and optimization. A mathematical model has been developed to understand the principal processes of SPME by applying basic ...
