Microbiological quality analysis of organically grown oilseed products

In recent years, seed bread has become one of the favourite breads for consumers, due to its better taste, nutritional value, and positive health effects. This paper illustrates the process of the microbiological quality analysis of organically grown oilseeds, from which many different products can be obtained by cold pressing, including seeds and their semi- products that can be added to the bread. Since these products are not thermally treated in any way, their microbiological safety is questionable. Therefore, the goal of this paper was to implement microbiological control of those products and to compare the obtained parameters with the norms prescribed by the Food Hygiene and Food Microbiological Laws (NN 81/2013). The conducted microbiological methods conform to the requirements prescribed by Croatian norms which are based on the ISO-9001 quality standards. A total of 40 samples, including 6 samples of cold pressed oils, 9 organic butters, 6 organic protein flours, 8 kinds of seeds and nuts, and 11 mixtures of oilseeds and edible nuts for bread and crackers, were collected and analysed on a number of aerobic mesophyllic bacteria, bacteria of the Enterobacteriaceaefamily, moulds and yeasts. The samples were also screened for the presence of pathogenic Salmonella and Listeria monocytogenesspecies, and sulphite-reducing clostridia, dependent on the norms prescribed by the Law. It was shown that the measured values did not exceed the prescribed normative values in all samples.
