“…A statistically significant difference ( p < 0.01) between the samples with different concentrations of added blueberry pomace was demonstrated for the parameters L*, a* and b*, as was a statistically significant difference in the parameter ΔE ( Figure 4 ), which describes the degree of difference between individual samples and the control without the addition of blueberry pomace. However, the lower stability of anthocyanins is a potential disadvantage of using blueberry pomace in edible coatings [ 54 ].…”

Studies dealing with the development of edible/biodegradable packaging have been gaining popularity since these commodities are marked as being ecofriendly, especially when byproducts are incorporated. Consequently, this study aimed at the development of chitosan-based coatings with plant byproducts. Their sensory properties, colour attributes, occurrence of cracks in microstructure and biodegradability were analysed. Coatings containing grape and blueberry pomace had statistically significantly (p < 0.05) higher levels of colour intensity. Coating samples were characterised by lower aroma intensity (3.46–4.77), relatively smooth surface (2.40–5.86), and low stickiness (2.11–3.14). In the overall hedonic evaluation, the samples containing parsley pomace in all concentrations and a sample containing 5% grape pomace achieved a statistically significantly (p < 0.05) better evaluation (5.76–5.93). The lowest values of the parameter ΔE2000 were recorded for the sample containing 5% parsley pomace (3.5); the highest was for the sample with 20% blueberry pomace (39.3). An analysis of the coating surface microstructure showed the presence of surface cracks at an 80 K magnification but the protective function of the edible coating was not disrupted by the added plant pomace. The produced samples can be considered to have a high biodegradability rate. The results of our experimentally produced coatings indicate their possible application on a commercial scale.

“…picardii and established that the main compounds were chlorogenic and quinic acids, dicaffeoylquinic acid isomers and flavonoid gnaphaliin A. According to Karača et al [ 65 ], the most abundant phenolic compounds present in the water extract prepared from commercially available H. italicum flowers, were caffeic acid, chlorogenic acid, and its derivatives. Kramberger et al [ 66 ] found that caffeoylquinic acids and pyrones were the most prevalent compounds in H. italicum ssp.…”

Helichrysum italicum is a Mediterranean plant with various pharmacological activities. Despite extensive reports on the bioactivity of the plant, its clinically studied applications have not yet been reviewed. The aim of our study was to gather information on the internal use of H. italicum and its bioactive constituents to determine its efficacy and safety for human use. We reviewed research articles that have not been previously presented in this context and analyzed relevant clinical studies with H. italicum. Cochranelibrary.com revealed six eligible clinical trials with H. italicum that examined indications for pain management, cough, and mental exhaustion. Although the efficacy of H. italicum has been demonstrated both in in vitro tests and in humans, it is difficult to attribute results from clinical trials to H. italicum alone, as it has usually not been tested as the sole component. On the other hand, clinical trials provide positive information on the safety profile since no adverse effects have been reported. We conclude that H. italicum is safe to use internally, while new clinical studies with H. italicum as a single component are needed to prove its efficacy. Based on the recent trend in H. italicum research, further studies are to be expected.

“…The results presented in the paper (Karača et al, 2019) became interesting. They show the possibility of the food films formation based on the combined "alginate-pectin" hydrogel with the Helichrysum italicum extract as a source of polyphenols in the matrix, which can reduce microbial contamination on the surface of food products, that are placed in such films.…”

Analysis of innovative technologies of hydrogels from uronate polysaccharides and biodegradable films on their basis

The article is devoted to the analysis of the state and dynamics of scientific developments in the field of creating products for life and health, based on hydrogels from uronate polysaccharides (HUP). The article is reflected the results of the global scientific research monitoring and their changes in the field of technologies for the creation and use of HUP. The results of a retrospective analysis of existing technologies based on poorly studied in the field of food technologies uronic acids, as glucuronic, idouronic, hyaluronic were presented. The study showed, that nowadays the industry of products with their content is acquiring market traits, although it has insufficient scientific substantiation. Development segments with widely used uronate polysaccharides – pectins and alginates – according to the types of hydrogels (swollen hydrogel, cross-linked hydrogel, xerogel) were developed. The article presents examples and identified the required properties of substances intended for immobilization or encapsulation in the hydrogel matrix of uronate polysaccharides. The basic principles of uronate polysaccharides crosslinking chains in the hydrogel phase are determined. Possible methods of biologically active substances (BAS) retention in the matrix of uronate polysaccharides to reduce the risk of premature oxidation, destruction, decomposition, decomposition, evaporation were described. The search for information allowed us to identify key technological areas for the development of scientific research on the creation and use of HUP to improve people's lives and health. The archives of the world's leading publications in the field of food chemistry, biotechnology, food engineering, chemistry of new materials, food polymers and hydrocolloids were analyzed. The authors used in their work the resources of the Science Direct search system, which made it possible to determine the most promising and modern lines of development of HUP technologies and products based on them. The analysis of technologies has shown that existing innovative technologies are formed on “basic” technologies for producing solutions of high-molecular compounds under various conditions. Active modernization is carried out in the direction of creating products with immobilized biologically active substances, as well as in attempts to compose a composition with other polysaccharides and/or peptide components. The article notes that existing technologies allow developing other technologies with the help of which it is possible to expand the field of HUP application.
