Abstract: The present invention provides a method for measuring the body fat percent and fat accretion during pregnancy, which preferably utilizes a Fourier transform near infrared spectroscopy (FT-NIR) fat determination method. The FT-NIR results can be used to measure and monitor body fat percent, and used to measure the mother's fat accretion rate. A method to monitor weight gain in a pregnant subject is provided wherein the body fat percentage of the subject is maintained at a constant level during gestation, and the subject's fat accretion rate is monitored so as to follow the fat accretion rate provided by using pre-defined fat accretion determination formulae. By measurement of the body fat percent and fat accretion rates, the weight gain of a subject can be monitored and/or controlled during pregnancy.

Abstract: A new rapid Fourier transform near infrared (FT-NIR) spectroscopic method is described to screen for the authenticity of edible oils, and in particular, extra virgin olive oils (EVOO). To screen these oils, the samples to be tested are pre-classified into one of a series of classification groups using a suitable classification criteria, such as fatty acid (FA) content. As a result, the oils are classified into Groups having similar properties. FT-NIR partial least squares (PLS1) calibration models are prepared for each group, based on FT-NIR analysis of authentic oils, and oils spiked with a specific type and amount of an adulterant. Using these different PLS1 calibration models, a more rapid method for analyzing commercial extra virgin olive oils for adulteration is provided.

Abstract: A new rapid Fourier transform near infrared (FT-NIR) spectroscopic method is described to screen for the authenticity of extra virgin olive oils (EVOO) and to determine the kind and amount of an adulterant in EVOO. To screen EVOO, a partial least squares (PLS1) calibration model was developed to estimate a newly created FT-NIR Index based on the carbonyl overtone absorptions in the FT-NIR spectra of EVOO and other mixtures attributed to volatile (5200 cm?1) and non-volatile (5180 cm?1) components. Spectra were also used to predict the fatty acid (FA) composition of EVOO or samples spiked with an adulterant using previously developed PLS1 calibration models and modified for this purpose. To identify the type and determine the quantity of an adulterant, gravimetric mixtures were prepared by spiking an EVOO with different concentrations of each adulterant. Based on FT-NIR spectra, four PLS1 calibration models were developed for four specific groups of adulterants each with a characteristic FA composition.

Abstract: A method of in-vivo fat measurement of humans or animals by scanning the ear of the subject using a fibre optic probe delivering a light beam of Near infrared wavelengths provided by a NIR source. Passing the beam through an interferometer to encode data from the whole spectral range simultaneously. Detecting reflected light by a detector and applying Fourier Transform techniques to determine the intensity of the light in at least one narrow wave band selected for its correspondence to a form of fat. Recording the NIR response and determining the fat content of the body by either comparison to known reference samples or by use of an empirical formula.

Abstract: A method for the rapid analysis of the fatty acid components present in a fat and/or oil-containing material is provided wherein the levels and types of fatty acids present in a sample are determined using Fourier Transform Near Infrared (FT-NIR) spectroscopy. The FT-NIR technique is developed by preparing a calibration matrix based on FT-NIR and Gas Chromatography (GC) analysis of known standards, and subsequently using the calibration matrix to analyze the FT-NIR spectral data obtained from a sample to be tested.
