  • METHOD FOR PREDICTING A PROPERTY VALUE OF INTEREST OF A MATERIAL
    Publication number: 20230194415
    Abstract: The present invention relates to a computer-implemented method for predicting a property value of interest in a sample investigated by infrared spectroscopy. The method aims at generating a calibration function. To this end, a set of calibration samples is selected, whereby outliers are identified and removed from the set of calibration samples. Outliers are determined using principal component analysis and singular value decomposition. The threshold value separating outliers from the remaining samples is calculated on the basis of a predetermined formulae. The threshold value may also be increased stepwise in order to dynamically set the threshold value, which is preferable for spectroscopic devices not operated under laboratory conditions.

  • Oil comprising at least one polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA)
    Patent number: 11666062
    Abstract: The present invention relates to an oil comprising at least one polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA). It is found that LC-PUFA-containing oil are susceptible to gelling by formation of microscopic crystals during storage ultimately resulting in unfavorable quality and handling properties. This problem has been particularly observed with a microbial oil comprising at least about 25% by weight LC-PUFA and a moisture content of 0.2 to 5% by weight. Surprisingly, it has been found that a LC-PUFA-containing oil as described above is effectively stable and does not show gelling properties under conventional storage conditions, if the oil composition as such contains less than about 8% preferably less than about 5% by weight of free fatty acid in the residual moisture of the oil.
