Abstract

Nowadays, the popularity of snack foods is increasing due to the fast-paced lifestyle of society. Thanks to the prevailing trends related to a healthy lifestyle and organic food, the need to create new products is increasing, but also more and more attention is being paid to high nutritional value. The aim of the study has been to evaluate the energy, nutritional, and health-promoting value of freeze-dried vegetable-based products with hydrocolloids as structure forming additives. The research included mathematical estimation of the energy and nutrients content, as well as selected health-promoting components, such as vitamins and micro- and macro-nutrients. The calculation was based on tabular data of the nutritional values each components of the products. In addition, the quality of the bars has been assessed by means of the daily requirement and the nutritional quality index. The bars have proven to be characterized by high energy and nutritional and health-promoting value. The Index Nutritional Quality (INQ) indicator has shown that the tested products are incorrectly adjusted in terms of the content of nutrients in relation to the energy supplied. The broccoli bar has turned out to be the best option because it has the highest content of protein, fat, and all the relevant vitamins and minerals. Obtained results verified that tested snacks were not enough to cover daily intake of specific nutrients, but introducing such products to balanced diet may have beneficial influence on human health and well-being.
