Evoluzione del profilo chimico e microbiologico di un cumulo di sansa stoccato all’aperto

Pomace produced by a 3-phases “watersaving” olive mill was stored outdoors as usually happens in Italy. The pomace pile resulted was 6,00 m length, 1,60 m width, 0,90 m height. The pile was left exposed to atmospheric events for almost ten months, while we took samples of pomace at 30 cm depth from the top of the pile during the whole period of outdoor storage. We carried out chemical and microbiological analysis from each pomace sample, to determinate the content of the following parameters: oil content, water content, total phenols content, lactic bacteria, enterobacteria, yeasts and mold content. The results obtained seems to show some kind of trend related to climatic variations and time of outdoor storage but, due to the small amount of samples, the nature and origin of pomace used, the lack of research using same conditions, does not verify the thesis supposed. Anyway, the results obtained strongly suggests further and wider investigations
