Heat Treatment: Precision Fumigation with Benefits

Heat Treatment: Precision Fumigation with Benefits

Vasilis Sotiroudas, Food Scientist, Heat Treatment specialist Thessaloniki, Greece info@agrospecom.gr   End of an era Use of Methyl Bromide (MeBr) has been banned in most developed countries since 2007. From January 1st 2015, it is not available anywhere as a fumigant for flour mills and other industries. Several fumigation alternatives have been tried around the world with heat treatment being one of them. But how good are these compared to good old MeBr? Can such alternatives be used for precise fumigation, i.e. a tightly controlled and monitored fumigation process? Methyl Bromide has been a good fumigant, but not excellent since the main disadvantage of gas fumigants is that they need airtight buildings. And in the real world, very few buildings are made airtight or can become airtight with proper sealing work. The majority of buildings will never hold the gas, especially on a windy day or when there are significant temperature differences between day and night.     The Heat Advantage Heat treatment has been practiced worldwide for a few years and is by now deemed a very effective replacement of MeBr for structural fumigation. Insects die at temperatures above 50oC because the proteins in their bodies coagulate, their salt equilibrium becomes damaged and they dry out. All insect stages are affected and no resistance to heat has been observed in the lab or in the field. Electricity, gas, petrol and steam can be used to generate heat for insect extermination. In our work, we have found out that each type of heater has its plusses and minuses. Electrical heaters (Photo 1) are easy to use, easy to handle...

Statistical Process Control

Statistical Process Control

The December 2013 issue of the “Trofima and Pota” magazine, hosted the article “Statistical Process Control” by Mr. Stephanos Kirkagaslis. SPC was developed by Motorola in 1981 and was been extensively used in the automotive industry (e.g. Toyοta) aiming to the minimization of scrap and rework. The article overviews the basic principles behind the SPC concept focusing on an example of net weight. However, SPC can be applied on a vast range of parameters within a food industry, e.g. humidity, viscosity, micro parameters etc, contributing towards food safety and production cost reduction.   Related Files...
