<p>Noninvasive process for estimating the ratio between fat content and water content of a substance, preferably animal tissues and to deduce the fat mass and the lean mass, comprises simultaneously measuring three infrared lines radiated and injected into the substance or tested tissues, by comparing the direct absorption (transmission) or indirect (reflection-diffusion). Noninvasive process for estimating the ratio between fat content and water content of a substance, preferably animal tissues and to deduce the fat mass and the lean mass, comprises simultaneously measuring three infrared lines radiated and injected into the substance or tested tissues, by comparing the direct absorption (transmission) or indirect (reflection-diffusion), where the: first line is related to lipid and located at 930 nm +- 15 nm; second line is related to water and located at 970 +- 40 nm; third line is the standard line located outside of absorption peak of analyzed elements e.g. 850 nm for animal flesh; and +- represents the spectral window in which a line can be selected.</p> |
