RESEARCH OF THE SAFETY INDICATORS OF BERRY SAUCES WITH SEAWEED’S RAW MATERIALS

Abstract

The current thing now is the matter regarding enrichment of food products with organic iodine, which is caused by iodine deficiency in the food ration of most of the country's population and by the country-wide radionuclide pollution, which leads to a hundredfold increase of risks of the thyroid body radiation. In this regard, there were developed the technologies of the berry sauces with the addition of the seaweed’s raw materials, as the iodine-concentrating component. The technologies of blueberry-cranberry sauces with guelder-rose juice, cornel-bilberry sauce with guelder-rose juice and blueberry-buckthorn sauce with guelder-rose juice were developed. This work is dedicated to a research of safety indicators of the developed sauces. There were used the hydrated seaweeds of Laminaria, of Fucus, of Undaria pinnatifida as iodinated additives. The following microbiological indicators were determined: the quality of mesophilic aerobic and optionally anaerobic microorganisms (МAOАnM), mold, yeast and lactic acid bacteria, and the presence of the coliform bacteria (CB) bacteria. The study results showed, that there are no microorganisms in the finished products, which may result the damage of the product after pasteurization. It was identified, that the own organic acids of the prepared sauces will be sufficient to ensure the microbiological clearness and the use of the additional preserving agents does not make sense. Toxicological indicators, namely the mass fractions of lead, cadmium, arsenic and mercury, have been studied. It has been established that the content of toxic elements in test samples is hundreds of times less than permissible. The toxicological indicators were studied, namely, the mass fractions of lead, cadmium, arsenic and mercury. It was identified, that the content of toxic elements in test samples is hundreds of times less than permissible. Thus, it is proved that the sauces made according to the developed technology, comply with the requirements of the regulatory documents according to the safety indicators. Moreover, it is proved, that that the addition of the seaweed’s raw materials does not worsen these indicators. To confirm the obtained data, the sample with the highest seaweed content was examined by an independent laboratory accredited according to DSTU ISO/IEC 17025 with the issuance of the appropriate test report.
