Study of regularities of distributing powdered dietetic additives in coarse dispersed foodstuffs

Abstract

Abstract. An important intervention in the composition of food products is enrichment of food with micronutrients. In this regard, the authors investigated how the additive with the corresponding trace element will be distributed in the food product, and in this case, in minced meat, in order to meet the human needs for microelements.Micronutrient deficiencies have a significant impact on the nutritional status and health of the population in well developed and developing countries. These deficiencies cause a delay in the growth of children, various diseases, mortality, brain damage, reduced cognitive capacity and the ability of people of all ages. The global scale of micronutrient deficiencies in dietary intakes, in particular the lack of trace elements, has led to the development of powdered dietary supplements containing essential elements that enrich the coarse-type food products to increase their nutritional value. The dietary supplement should provide the daily requirement of trace elements in the human body; therefore, it should be added to the product in a normalized amount and evenly distributed in the product.Two nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) analysis were performed to determine the distribution of the additive in food products. The analysis was carried out in two stages respectively: study of molecules mobility by measuring the spin-spin relaxation time (Т2) and spin-lattice relaxation (Т1) on a pulsed NMR spectrometer; establishment of a connection between the exponent of the amplitude of the sample A 0 and its mass. Based on the data obtained, as a result of the measurement, a curve is constructed for the dependence of the amplitude of the echo signal from the value (time interval between the probing pulses). The spin label used in this work is one of the first variants of a paramagnetic probe-an easily accessible transition metal ion Mn 2+. According to the constructed graphs and tomograms from the results of the studies, it is possible to study the characteristics of this dietary supplement and the expediency of its use.Key words.

Серйозним втручанням до складу продуктів харчування вважається збагачення харчових продук-тів мікронутрієнтами. У зв'язку з цим досліджено, як добавка з відповідним мікроелементом буде розподілятися у продукті харчування, а в даному випадку у м'ясному фарші, для того, щоб задовольнити потреби людини у мікроеле-ментах. Проведено два аналізи методом ядерного магнітного резонансу та електронного парамагнітного резонансу для визначення розподілу добавки в продуктах харчування. Аналізи проводились відповідно у два етапи: дослідження ру-хливості молекул шляхом вимірювання часу спін-спінової релаксації (Т 2 ) та спін-градкової релаксації (Т 1 ) на імпульс-ному спектрометрі ЯМР; встановлення зв'язку між показником амплітуди зразка А 0 і його масою. На основі отрима-них в результаті вимірювання даних побудовано криву залежності амплітуд...

Investigations of the Functional and Technological Properties of Dough Semi-Products Enriched With Dietary Supplements

“…But provision of the homogeneity of distribution of introduced microelements in the volume of a food product remains an unsolved question. One of methods that allow to solve it is the use of dietary supplements based on chelate complexes, in food technologies [7]. This direction is new in food technologies and needs experimental studies.…”
