  • Processing of soybean meal into concentrates and testing for Genetically Modified Organism (GMO)
    Vindiš, Peter ...
    The purpose of the paper is to show how the soybean meal is processed into thefeed concentrate and how the GMO content is tested when the soybean meal isaccepted in the feed concentrate factory. ... Design/methodology/approach: Afteracceptance of the soybean meal the analysis for the protein and moisture contend is made by the use of Inframatic. The average monthly sample is sent to an external laboratory for testing for GMO content. According to the regulations the GMO content must not exceed 0,9% and is determined by the PCR (polymeraze chain reaction) method. The soybean meal is processed into the feed concentrate by the use of hammer mill, feed mixer and pellet mill. Ten analyses for GMO content have been performed by establishing the influence of the origin on the GMO content; the average percentage of GMO in the soybean meal was 0.3%. Findings: In two cases the results of analyses of the soybean meal were negative, which means that the soybean meal did not contain any GMO;in eight cases the test was positive, but none of them exceeded the sill of 0.9%. Irrespective of the supplier or origin the average percentage of the GMO in soybean meal is approximately identical, i.e., 0.3%. Only the soybean meal, arriving from Brazil, has a smaller percentage of the GMO, i.e., 0.22%. It means that not the supplier, but only the origin has an influence on the percentage of the GMO in soybean meal. Research limitations/implications: The research has been performed on soybean meal, arriving from Brazil and Hungary,where ten analyses for GMO content have been performed. Practical implications: On the average, the soybean meal coming from Hungary contains more GMO, i.e., 0,3%, than the soybean meal coming from Brazil, which contains0.22%. Originality/value: The research showed that most soybean meal were genetically modified, but in no case the limit prescribed by the regulations, i.e., 0.9%, was exceeded.
