Evaluation of Water Quality of Caño Tiburones in the Vicinity of the Arecibo Waste Disposal Site.
Abstract
The water quality of the Caño Tiburones estuary located near the Arecibo Landfill was evaluated in this research due to concerns regarding the potential impact of the landfill on the local community, which uses the estuary for recreational activities such as fishing.
Detection and Quantification of Corn Starch and Wheat Flour as Adulterants in Milk Powder by Raman Spectroscopy coupled with Chemometric Routines.
Abstract
Adulterating foods such as milk powder is a common practice in countries with no rigid policy on food quality control. This study employs Raman spectroscopy and chemometric analysis to detect milk powder (MP) adulteration with corn starch (CS) and wheat flour (WF) from 0.00 to 30.00% w/w concentrations.
