PROCJENA NEAKTIVNOSTI PROTUHRANJIVIH ČIMBENIKA OSJETLJIVIH NA TOPLINU U PUNOMASNOJ SOJI

The regular quality control on the adequacy of heat treatment of fullfat soybeans requires the application of rapid chemical methods. In the present work the trypsin inhibitor activity test and the urease test were applied on fullfat soya samples that were cooked in a pressured steam (toasted) or extruded at different temperatures and speed rates. In the case of toasting both of the results of the laboratory examinations proved that the heating was adequate, while in the case of the extruded samples the two tests gave different results. In the case of certain temperature and time combinations the more rapid and less accurate urease test claimed that the heat treatment reached the aim, while the results of the trypsin inhibitor activity test showed that the level of the inhibitors was still high and the fullfat soya was underheated.Redovita kontrola kakvoće primjerenosti toplinskog tretiranja punomasne soje zahtijeva primjenu brzih kemijskih metoda. U ovom radu primijenjeni su test aktivnosti inhibitora tripsina i test ureaze na uzorcima punomasne soje kuhane u pari pod pritiskom (tostirane) ili ekstrudirane na različitim temperaturama i brzinama. U slučaju tostiranja oba rezultata laboratorijskih ispitivanja su dokazala da je grijanje bilo primjereno, dok su u slučaju ekstrudiranja uzoraka oba testa dala različite rezultate. U slučaju određene temperature i vremenske kombinacije brzi i manje točan test ureaze potvrdio je da je toplinsko tretiranje postiglo svrhu dok su rezultati testa aktivnosti inhibitora tripsina pokazali da je razina inhibitora još uvijek visoka, a punomasna soja nedovoljno zagrijana

Conceptos y métodos fundamentales en ecología del paisaje (landscape ecology). Una interpretación desde la geografía

La ecología del paisaje nace en estrecha vinculación con la geografía y vive un desarrollo espectacular a partir de la segunda mitad del siglo XX. En la actualidad, es una perspectiva científica transdisciplinaria, consolidada y reconocida, que intenta comprender y ayudar a resolver algunos de los principales retos ambientales contemporáneos en la conservación del patrimonio natural y cultural. En estas páginas, se repasa de forma sintética los conceptos y los métodos, eminentemente cuantitativos, utilizados por la ecología del paisaje para analizar la situación y la evolución de los paisajes.L'ecologia del paisatge neix en una vinculació ben estreta amb la geografia i viu un espectacular desenvolupament a partir de la segona meitat del segle XX. En l'actualitat, és una perspectiva científica transdisciplinària, consolidada i reconeguda, que intenta comprendre i ajudar a resoldre els principals reptes ambientals contemporanis pel que fa a la conservació del patrimoni natural i cultural. En aquestes pàgines, es repassa de forma sintètica els conceptes clau i els mètodes, eminentment quantitatius, emprats per l'ecologia del paisatge per analitzar la situació i l'evolució dels paisatges.L'écologie du paysage née en relation à la géographie et connait un développement notable à partir de la deuxième moitié du XXème. siècle. Actuellement, est une perspective scientifique transdisciplinaire, consolidée et reconnue qui veux comprendre et aider à résoudre quelques des défis enviromentales contemporaines de la conservation du patrimoine naturel et culturel. Dans ces pages se repassent de manière synthétique des concepts et des méthodes, éminemment quantitatives, qui sont utilisés par l'écologie du paysage à fin d'analyser l'état et l'évolution des paysages.Landscape ecology was born narrowly linked with geography and suffers a fast paced development during the second half of the 20th century. Currently, it is a transdisciplinary scientific perspective, consolidated and recognized, that aims to understand and to aid solving some of the main contemporary environmental challenges for the conservation of cultural and natural patrimony. In this paper, key concepts and methods, mostly quantitative, used in landscape ecology in order to analyze the situation and evolution of landscapes are reviewed in a synthetic manner
