Dati pubblicati inerenti il tema <strong>di</strong> ricerca:1. Anese, M., Sovrano, S. 2006. Acrilammide negli alimenti: proprietà, meccanismi <strong>di</strong>formazione, meto<strong>di</strong> <strong>di</strong> analisi e strategie volte a minimizzarne lo sviluppo. IndustrieAlimentari, 45 (459), 625-636.La pubblicazione nel 2002 dei risultati <strong>di</strong> un'indagine, condotta dall'Università <strong>di</strong> Stoccolma, relativa alle elevateconcentrazioni <strong>di</strong> acrilammide, riscontrate in uno svariato numero <strong>di</strong> derivati amidacei, ha generato vastapreoccupazione a causa del fatto che questo composto è stato classificato dalla Agenzia Internazionale per la<strong>Ricerca</strong> sul Cancro come "probabile sostanza carcinogenica per l'uomo". Conseguentemente, sono state avviatein tutto il mondo numerose ricerche, finanziate da organismi nazionali e internazionali, sui meccanismi e i rischilegati alla presenza <strong>di</strong> questo composto negli alimenti trattati termicamente. Nonostante i molti progressi <strong>di</strong>questi ultimi anni sulla conoscenza dei meccanismi <strong>di</strong> formazione dell’acrilammide negli alimenti, si è tuttaviaancora molto lontani da una chiara ed esaustiva comprensione del ruolo delle <strong>di</strong>verse variabili compositive e <strong>di</strong>processo sulla formazione <strong>di</strong> questa molecola. In questo lavoro sono stati esaminati, sulla base delle informazionioggi <strong>di</strong>sponibili, proprietà, meto<strong>di</strong> <strong>di</strong> analisi, meccanismi e cinetiche <strong>di</strong> formazione dell’acrilammide neglialimenti, e descritti i principali interventi tecnologici volti a ridurne la formazione.2. Anese, M., Sovrano, S., Bortolomeazzi, R. 2008. Effect of ra<strong>di</strong>ofrequency heating on acrylamideformation in bakery products. European Food Research & Technology, 226 (5), 1197-1023.This work was addressed to study the influence of ra<strong>di</strong>ofrequency (RF) heating on acrylamide (AA) formation inbakery products. To this purpose, leavened cakes and short dough biscuits were baked to a final moisture of3.5% and 3.0% respectively, by means of conventional convection heating or <strong>di</strong>fferent combinations of conventionaland RF heating. Results showed that, with respect to the baking process entirely carried out in an aircirculatingoven, the RF-assisted baking process, i.e. the application of RF heating in the last stages of the bakingprocess, resulted to be a promising strategy to keep low the AA levels in the bakery products. In particular, thebest results were obtained for products which were moved from the hot-air baking to the RF heating when theirresidual moisture was still fairly high (around 10%). Results also suggested that, when very low values of residualmoisture are required, this technological intervention is more suitable to thin bakery products, such as biscuits,than to thick products, such as leavened cakes, because of excessive browning in the internal portion as aconsequence of the RF heating.3. Anese, M., Bortolomeazzi, R., Manzocco, L., Manzano, M., Giusto, C., Nicoli, M.C. 2009.Effect of chemical and biological <strong>di</strong>pping on acrylamide formation and sensory properties indeep-fried potatoes. Food Research International, 42, 142-147.The objective of this work was to study the effect of chemical and biological pre-treatments on acrylamide formationin deep-fried potatoes. Prior to deep-frying, potatoes cubes were subjected to lactic acid fermentation inthe presence or in the absence of glycine, as well as to immersion in an aqueous solution of the amino acid alone.The effects of each pre-treatment on deep-fried potatoes were compared by evaluating acrylamide formation,browning development as well as sensory attributes and preference. Results showed that deep-fried potatoes subjectedto the glycine and fermentation pre-treatments had 35 and 50% less acrylamide content than the water<strong>di</strong>ppedones. Lactic acid fermentation in the presence of glycine resulted the most effective in decreasingacrylamide formation up to 70%. Such a pre-treatment <strong>di</strong>d not affect the sensory perceived browning, flavour,sourness and crispness of the deep-fried potatoes. Moreover, accor<strong>di</strong>ng to the results of a pair comparison preferencetest, no significant <strong>di</strong>fferences in preference were found among the samples.4.
