IDENTIFICATION OF ADULTERANT AND ALCOHOL ROUTE IN BIODIESEL USING MID-INFRARED ABSORPTION SPECTROSCOPY

Polymer Identification using Mid Infrared Spectroscopy

Synthetic polymers are very widely used today, with diverse applications in various industries such as food, automotive, and packaging. The quality of plastic products depends on the quality of the polymers or polymer blends used during manufacturing, so identity verification and quality testing of those materials during every stage of manufacturing is necessary to ensure that only high-quality...

Human Milk Analysis Using Mid-Infrared Spectroscopy.

BACKGROUND The composition of human milk is known to vary with length of gestation, stage of lactation, and other factors. Human milk contains all nutrients required for infant health but requires fortification to meet the needs of low-birth-weight infants. Without a known nutrient profile of the mother's milk or donor milk fed to a baby, the composition of the fortified product is only an esti...

Mid-infrared upconversion spectroscopy

assessing absorption coefficient of hemoglobin in the breast phantom using near-infrared spectroscopy

objectives in this study, the absorption coefficient of hemoglobin (hb) was used to distinguish between normal and abnormal breast tissue. materials and methods a near-infrared source (637 nm) was transmitted from major and minor vessels of a breast phantom containing 2×, 4× concentrations of oxy- and deoxy-hb. the absorption coefficients were determined from spectrometer (sm) and powermeter (p...

Rapid Testing for Adulteration of Yogurt Candy using Near-infrared Spectroscopy and Adulterant Screen

Melamine is an adulterant commonly found in milk, as it can increase the nitrogen content. Therefore, its apparent protein content, resulting in a better market price. Melamine adulteration can be fatal, as was highlighted in 2008 when six infants died due to melamine adulteration in milk powder and thousands were sickened in China. Consequently, there have been stricter regulations globally an...
