A value chain approach is needed for an efficient mycotoxin reduction in the food and feed chain, starting from measures to prevent contamination in the field, to control measures to avoid mycotoxin production during storage and over the process line, until final consumption. Grain cleaning is the most effective post-harvest mitigation strategy to reduce high levels of mycotoxins due to the efficient removal of mold-infected grains and grain fractions with high mycotoxin content. Several studies have been performed during the last years to investigate the reduction of deoxynivalenol in wheat and barley, ergot in rye, and total aflatoxins in peanuts and maize. Typical cleaning steps include (i) mechanical size separation and dust removal by aspiration, (ii) separation based on density differences, and finally (iii) optical sorting. Within grain milling, often a fourth cleaning step is included, (iv) separation of bran, and for wet processing as in malting, (v) washing can be introduced. Recently a completely new technology was developed for grain cleaning and monitoring based on the spectral properties of fluorescence. These well proven and recent innovations for mycotoxin reduction will be described further in the talk, taking a whole value chain approach.

Abstract
A value chain approach is needed for an efficient mycotoxin reduction in the food and feed chain, starting from measures to prevent contamination in the field, to control measures to avoid mycotoxin production during storage and over the process line, until final consumption. Grain cleaning is the most effective post-harvest mitigation strategy to reduce high levels of mycotoxins due to the efficient removal of mold-infected grains and grain fractions with high mycotoxin content. Several studies have been performed during the last years to investigate the reduction of deoxynivalenol in wheat and barley, ergot in rye, and total aflatoxins in peanuts and maize. Typical cleaning steps include (i) mechanical size separation and dust removal by aspiration, (ii) separation based on density differences, and finally (iii) optical sorting. Within grain milling, often a fourth cleaning step is included, (iv) separation of bran, and for wet processing as in malting, (v) washing can be introduced. Recently a completely new technology was developed for grain cleaning and monitoring based on the spectral properties of fluorescence. These well proven and recent innovations for mycotoxin reduction will be described further in the talk, taking a whole value chain approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
