Assessment of the quality of cream-white candy with the addition of fruit and berry paste during storage

One of the trends in modern nutrition is targeting people who care about their health. Confectionery made from sugar is in stable demand among people of different age groups, and research into their enrichment with vital nutrients is promising. One of the ways to implement such a task is the use of fruit and berry processing products, in particular in the form of pastes, during the production of candies. The purpose of the research was to evaluate the quality of cream-whipped candies with the addition of apple, quince and blackcurrant paste (40: 50: 10) during storage. It was established that the process of hydrolysis of the lipid component of candies with paste occurs at a higher rate compared to the control. This is due to their higher acidity and moisture. However, the fats of candies with the addition of fruit and berry paste are less prone to the formation of peroxides, which is explained by the presence in their composition of a significant number of polyphenolic compounds with pronounced antioxidant properties (anthocyanins and catechins), which are absent in the control sample. In particular, on the 60th day of storage, the value of the peroxide value for the sample with the additive was 27.9 % less than that of the control product. It has been established that candies with paste lose moisture more slowly due to the higher content of non-starch polysaccharides. Thus, on the 60th day, the moisture content of the control decreased by 11.33 %, and the product with paste decreased by 8.72 %. Smaller moisture losses ensure greater stability of their rheological characteristics during storage. It was noted that the strength and density of such candies increase more slowly than in the sample without the additive. The results of the research indicate the compliance of cream-whipped candies with fruit and berry paste to the normative storage terms in terms of oxidative stability of the lipid complex, physico-chemical and sensory indicator

Improving the Marmalade TECHNOLOGY by Adding A Multicomponent Fruit-and-berry Paste

The necessity to optimize the nutritional value of marmalade by using physiologically functional ingredients containing vitamins, dietary fiber, minerals, and other useful substances in its composition has been substantiated. Specifically, using the multicomponent fruit-and-berry paste from apples, quince, black currant has been proposed, which is obtained by an improved technique. The technique is characterized by the rapid dehydration (30...45 s, at 50 °C) of the blended paste in a rotor plant to 28...30 % of dry matter. When studying the dependences of the effective viscosity of paste compositions on the shear rate, it was found that the paste that demonstrated the best indicators contained apple in the amount of 40 %; quince ‒ 50 %; black currant ‒ 10 %. It has been experimentally proven that the rational amount of fruit-and-berry paste is 30 % with a decrease in agar by 30 %. This makes it possible to obtain the jelly-fruit marmalade on agar with a mass fraction of moisture of 18 %, a total acidity of 10 degrees, and a mass fraction of reducing substances not more than 28 %. The products have a sweet-sour taste, with a pleasant aftertaste and the smell of black currant, rich purple color, jelly-like form, and non-tight consistency. The strength of the new samples of marmalade with a decrease in the amount of agar is 18.9 kPa, similar to that of control. The improved technology makes it possible to expand the range of "healthy products", which is achieved by the partial replacement of raw materials with a fruit-and-berry paste, which contains a significant number of physiologically functional components. This allows for an increase in the nutritional value of marmalade, as well as a decrease in the formulation amount of agar, which is expensive, by 30 %. In addition, gentle concentration modes improve the process of paste makin

Sustainable Functional Food Processing

Functional nutrition is deeply connected with healthy lifestyle and sustainable food production, due to its positive health benefits and the use of economically underexplored and natural raw materials. Expectedly, it appeals to large number of interested consumers while becoming lucrative segment of the food industry with a fast-growing market fueled by new sociodemographic trends. Accordingly, functional juices and beverages made of indigenous fruits are interesting niche for various food market stakeholders. Here, biologically active compounds (BACs) and probiotics that have positive health effects in functional foods (juices) are mostly thermolabile. This is especially important for industry that still employs classical heat treatments (e.g., pasteurization), while being concerned with degradation of food quality in the final products. To prevent this, focus is on designing economic and ecological technologies that are able to preserve nutritional and sensory quality while maintaining microbiological stability in products. Such approaches are based on low-energy consumption and low-impact processing, e.g. “hurdle technology” that combines advanced and conventional methods (e.g., high-power ultrasound, pulse electric field). Food design is another important focus point for consumers’ sensory appeal and economic success of foods. Hence, technologies as 3D food printing can be particularly useful for manufacturing. Based on the above, presented topics are relevant to sustainable functional food production, functional fruit juices, BACs, “hurdle technology,” advanced food processing, 3D food printing, and authentic fruits

Anti-angiogenic and toxicity effects of Derris trifoliata extract in zebrafish embryo

Introduction: Derris trifoliata has been traditionally used as folk for the treatment of , rheumatic joints, diarrhoea, and dysmenorrhea, and rotenoids isolated from the plant have shown to exhibit anti-cancer properties. This study aimed to assess the toxicity effects and antiangiogenic activity of extract of Derris trifoliata on zebrafish embryo model. Materials and Methods: Zebrafihs embryos were treated with aqueous extract of Derris Trifoliata to evaluate its effects on angiogenesis and zebrafish-toxicity. Angiogenic response was analyzed using whole-mount alkaline phosphatase (AP) vessel staining on 72 hours post fertilization (hpf) zebrafish embryos. Results: 1.0 mg/ml concentration was toxic to zebrafish embryos and embryos exposed to concentrations at 0.5 mg/ml and below showed some malformations. Derris trifoliata aqueous extract also showed some anti-angiogenic activity in vivo in the zebrafish embryo model wereby at high concentration inhibited vessel formation in zebrafish embryo. Conclusions: The anti-angiogenic response of extract of Derris trifoliata in zebrafish in vivo model suggest its therapeutic potential as anti-cancer agent
