Whey Protein Powder Analysis by Mid-Infrared Spectroscopy

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...

DETERMINATION OF BOTANICAL ORIGIN OF HONEY BY MID INFRARED SPECTROSCOPY (Mid-FTIR), COLORIMETRY AND CHEMOMETRIC ANALYSIS

The aim the investigation reported is to determine the potential of determining the botanical origin of honey by a combination of middle infrared spectroscopy, colorimetry and chemometric analysis. Forty-three samples from three types of honey (acacia, linden, and honeydew) are subjected to Fourier transform mid-infrared (Mid-FTIR) spectroscopy. Transmittance spectra with wave numbers from 600 ...

Rapid Characterization of Tanshinone Extract Powder by Near Infrared Spectroscopy

Chemical and physical quality attributes of herbal extract powders play an important role in the research and development of Chinese medicine preparations. The active pharmaceutical ingredients have a direct impact on the herbal extract's efficacy, while the physical properties of raw material affect the pharmaceutical manufacturing process and the final products' quality. In this study, tanshi...

Probing ice clouds by mid-infrared extinction spectroscopy

Series of infrared extinction spectra of ice crystals were recorded in the 6000–800 cm −1 wavenumber regime during expansion cooling experiments in the large aerosol and cloud chamber AIDA of Forschungszentrum Karlsruhe. Either supercooled sulphuric acid solution droplets or dry mineral dust particles were added as seed aerosols to 5 initiate ice formation after having established ice supersatu...
