Chromatographic determination of vitamin content in a bar with dried tomatoes

Abstract

There exists a problem of unbalanced nutrition in the modern world. Consumption of vegetables and fruits is mainly seasonal and they are not consumed by everyone in the daily diet in sufficient quantities to meet the daily requirement for nutrients. Snack products, including various bars, are becoming increasingly popular among the population of our country. Often there is an insufficient amount of vitamins and other micronutrients with such products that are so necessary to ensure the health of the human body. Insufficiency of these nutrients causes various diseases, the condition of the skin, hair, nails, and even mood worsens.The goal of the research was to determine the amount of vitamins in a bar made from sunflower seeds with the addition of plant materials – crushed dried tomato fruits.The objects of the study were a candy bar with the addition of rusk crumbs, containing 15% of dried tomatoes by weight of the finished product and a control sample – kozinak.Tests were carried out on a Dionex Ultimate 3000 chromatograph using reverse phase chromatography on a Luna C18 column. This device is used to measure the content of a wide range of components in samples of substances and materials, solutions, food products and other objects of analysis.It has been found that with the addition of a herbal additive and cracker crumbs to the recipe, the quanitative composition of vitamins A and E in the finished product increased compared to the control sample.The results of the research can be used in the development of new food recipes.
