From generation to generation, edible palm oil has been a staple of the human diet and improved both nutrition health. The goal current research was determine whether it possible tamper with by adding natural potash (lake salt) red dye made from leaf sheath sorghum bicolor. In order create tainted known concentrations adulterant ratios, ranging 0.01-0.1% 0.1-1.0%, respectively, were produced in...
Significant effort has been targeted at reducing the risk of pathogens in U.S. beef products since the mid-1990s. These efforts were focused on Escherichia coli O157:H7 after it was declared an adulterant in ground beef or its components. Post-harvest interventions applied to hides and carcasses by beef processors resulted in significant progress. Effective pre-harvest approaches proved hard to...
A simple, rapid colorimetric method using label-free Ag NPs (silver nanoparticles) as probe for detection of melamine in raw milk was developed in this study. The assay relies on the fact that melamine can induce aggregation of Ag NPs, and thereby results in their yellow-to-red color change. The concentration of melamine in raw milk can be determined by monitoring with the naked eyes or a UVeVi...
BACKGROUND Cultivated ginseng is often introduced as a substitute and adulterant of Russian wild ginseng due to its lower cost or misidentification caused by similarity in appearance with wild ginseng. The aim of this study is to develop a simple and reliable method to differentiate Russian wild ginseng from cultivated ginseng. METHODS The mitochondrial NADH dehydrogenase subunit 7 (nad7) int...
Honey is one of the important traditional medicines since ancient times. In this paper, a case study was carried out using Near Infrared (NIR) spectroscopy techniques with Chemometrics to detect the Jaggery adulterants in the honey. This component used to prepare adulterant solution of different proportionate by manually and mixed with four types of different honey samples. Totally 160 spectra ...
Levamisole is an antihelminthic agent widely used as an adulterant of illicit cocaine recently implicated as a cause of antineutrophil cytoplasmic antibody (ANCA)-associated microscopic polyangiitis in cocaine abusers. An isolated case of membranous nephropathy (MN) associated with levamisole exposure has also been reported. We report the first case, to our knowledge, of a patient with both mic...
Dried parts of different plant species often look alike, especially in powdered form, making them very difficult to identify. Ruta graveolens, sold as a dried medicinal herb, can be adulterated with Euphorbia dracunculoides. The genomic DNA was isolated from the leaf powder (100 mg each) using the modified CTAB method. Internal transcribed spacer sequences of nuclear ribosomal DNA (nrDNA-I...
