Title: | Adsorption isotherms of pear at several temperatures | Authors: | Mitrevski V. Lutovska M. Mijakovski V. Pavkov, Ivan Babić, Mladen Radojčin, Milivoj |
Issue Date: | 1-Jan-2015 | Journal: | Thermal Science | Abstract: | The moisture adsorption isotherms of pear were determined at 15 °C, 30 °C, and 45°C using the standard static gravimetric method over a range of water activity from 0.112 to 0.920. The experimental data were fitted with isotherm equations recommended in ASAE Standard D245.5. In order to find which equation gives the best results, large number of numerical experiments were performed. After that, several statistical criteria proposed in scientific literature for estimation and selection of the best sorption isotherm equations were used. For each equation and experimental data set, the average performance index was calculated and models were ranked afterwards. After that, some statistical rejection criteria were checked (D'Agostino-Pearson test of normality, single-sample run test and significance and precision of the model parameters). The performed statistical analysis shows that the Guggenheim-Anderson-de Boer equation has the highest value of average performance index, but higher correlation between pair of parameters leads to lower precision of estimated parameters. | URI: | https://open.uns.ac.rs/handle/123456789/5447 | ISSN: | 03549836 | DOI: | 10.2298/TSCI140519082M |
