|Key words||Insect, cereals, weevil, disinfestation|
How does it work?
|Primary objective||The aim is to prevent or suppress harmful insects in bio-cereals by non-chemical methods.|
|Working principle|| Bio- or organic cereals products are specific in comparison with conventionally precessed cereals because of their higher sensibility and vulnerability to various insects’. No chemical applications are allowed. There are some attempts to find a solution for coping with the fact that harmful insects can be present at each developmental stage and can destroy the bio-grain.
Generally there are four different approaches under research and testing.
Methods combining the effect of CO2 and ethyl formate were researched and good results were achieved. Nevertheless because of the” BIO” label, this method cannot be used.
|Additional effects||Slight change in quality characteristics such as α-amylase activity, diastatic power, soluble protein, viscosity i.e., depending on the scale of used principles, parameters, conditions.|
|Important process parameters||Time, temperature, concentration, pressure, frequency i.e.|
|Important product parameters||moisture content|
What can it be used for?
|Products||Cereals, barley, rice i.e.|
|Operations||Disinsection before product/grain storage.|
|Solutions for short comings||These above mentioned technologies can be used as a replacement for conventional chemical methods.|
What can it NOT be used for?
|Products|| Not known yet.
Currently running test confirmed that vacuum storage of grain does not influence the germination.
|Operations||Not known yet.|
|Other limitations||Capital and energy intensity should be observed depending on the specific method applied.|
|Risks or hazards||When proper conditions not applied: grain destruction or degradation.|
|Maturity||at laboratory scale|
|Modularity /Implementation||It can be inserted into an existing production line|
|Consumer aspects||Not specified yet. Consumers expect their cereals free of insects. When they want to buy bio-cereals they expect that no chemical methods have been used.|
|Legal aspects||Regulation no. 178/2002.|
|Environmental aspects||Environmentally friendly.|
