Effect of extracting time and temperature on yeild of gelatin from different fish offal
PublicationCelem pracy było określenie optymalnych warunków otrzymywania żelatyny z różnych rodzajów odpadów powstających podczas obróki wstępnej lub przetwarzania surowców rybnych. Wydajność ekstrakcji żelatyny w 45°C z surowych skór łososia i kręgosłupów wynosiła 71-75% oraz 86% ze skór łososia wędzonego. W przypadku skór z marynowanego i solonego śledzia przemianie do żelatyny ulegało w tych warunkach około 100% kolagenu. Optymalny czas...

Application of Multivariate Adaptive Regression Splines (MARSplines) for Predicting Hansen Solubility Parameters Based on 1D and 2D Molecular Descriptors Computed from SMILES String
PublicationA new method of Hansen solubility parameters (HSPs) prediction was developed by combining the multivariate adaptive regression splines (MARSplines) methodology with a simple multivariable regression involving 1D and 2D PaDEL molecular descriptors. In order to adopt the MARSplines approach to QSPR/QSAR problems, several optimization procedures were proposed and tested. The effectiveness of the obtained models was checked via standard...
