76 MILLER / FEBRUARY 2019 "Wireless sensors for monitoring O ₂ and/or CO ₂ concentrations, relative humidity and temperature have been developed to enable the technical personnel record the data. Such development facilitates the analysis of the MA/CA treated enclosures without the presence of the technical personnel on site. Since the exposure time of MA/CA treatments last many days and the treated structures may be located at distant sites then the location of the operator, such development offers an excellent tool that can be incorporated to the package of the MA/CA treatments." High quality flour can be obtained only from high quality wheat. Protection of the beneficial qualities of wheat during storage depends on many factors. Among the detrimental factors that reduce the quality of wheat are insects and mic- roflora. Wheat kernels can be stored for extended periods of time, provided there is no insect infes- tation and their water activity can be kept low enough to prevent microbial growth. However, in aerated storages quantitative and qualitative losses still occur. Qualitative losses, for example, may consist of changes in physical appearance, in color change, loss of flavor, in nutritional degra- dation due to oxidation and increase in free fatty acids, the presence of insects or their fragments, or contamination by mold or the presence of my- cotoxins. If the moisture content is maintained sufficiently low, insects and quality loss remain the main concern for the quality preservation of wheat (Navarro and Donahaye, 2005). Although in modified or controlled atmospheres (MA/CA), the major emphasis is placed on the control of in- Modified and Controlled Atmospheres for the protection of wheat quality Shlomo Navarro Hagit Navarro Green Storage Ltd. snavarro@013.net Green Storage Ltd.
