Abstract:

The research work on the incorporation of Marrubium vulgare extract in the yogurt formulations and its effects on physicochemical and sensory properties were conducted. The obtained results revealed that the incorporation of Marrubium vulgare extract did not negatively influenced physicochemical parameters, with pH values varied from 4.37 ± 0.01 in natural Yogurt to 4.31 ± 0.01 in the 4% Marrubium yogurt, and titratable acidity varied significantly from 99.3 ± 0.5°D to 105.3 ± 1.2°D (p < 0.05). The water holding capacity (WHC) improved slightly, but significantly from 20.40 ± 0.03% to 20.67 ± 0.07% (p < 0.05). The results suggest a slight increase in titratable acidity, WHC, and viscosity (especially, at higher extract concentrations); however, further research is needed to refine this trend. Nutritionally, total solids, protein and fat content remained largely unchanged (p > 0.05), but led to a significant increase in ash content, from 0.63 ± 0.03% to 0.93 ± 0.03% (p < 0.05). Additionally, the total phenolic content was significantly increased from 5.25 ± 0.31 mg per 100 g to 7.30 ± 0.27 mg per 100 g (p < 0.05) and the antioxidant activity from 2.71 ± 0.19 mg per 100 g to 4.42 ± 0.24 mg per 100g (p < 0.05). The sensory evaluation revealed that Marrubium-enriched Yogurt received significantly higher ratings in flavor and overall acceptability (p < 0.05) compared to plain Yogurt. Texture ratings remained similar (p > 0.05). This study highlights the potential of Marrubium vulgare as a functional ingredient for Yogurt fortification, enhancing antioxidant properties, mineral content, and consumer acceptability.

Abstract:

Physicochemical changes could affect the quality of goat milk yoghurt. Yoghurt quality has been improved by incorporating a synbiotic derived from a prebiotic combined with probiotics. This study aimed to evaluate the effect of different concentrations of synbiotics (inulin of mangrove apple and Lactobacillus plantarum) in the physicochemical properties of goat’s milk yoghurt. This study used a Completely Randomized Design (CRD) with 5 treatments and 4 replications, with differences in the concentration of synbiotics as much as 0, 2, 4, 6, and 8%. The addition of synbiotics was significant (p < 0.05) in the sugar reduction, colour, and syneresis of yoghurt products. They did not significantly affect (p > 0.05) the firmness of yoghurt texture. This study provides support for the addition of synbiotics to improve physicochemical properties of goat’s milk yogurt.

Abstract:

According to the data and the results of clinical trials received in Nutrition Institute of ‘Russian Academy of Medical Sciences’, it was found that 80% of Russians suffer from lack of selenium. Saint-Petersburg University Innovation Company ‘Littoral’ has developed a biologically active food supplement ‘Selenium Alga plus’. The aim of this research was to investigate the possibility of using dietary supplement ‘Selenium Alga Plus’ in yoghurt manufacture. Almost all groups of the population consume such fermented milk drink as yogurt, so that it is considered that this method increasing selenium as the most effective. People suffering from diabetes may have lack of selenium in the organism, as well as healthy people. Since traditional yogurt contains 11% of sucrose, it is necessary to choose sweetening components with vegetable origin. Selecting sweetening components of vegetable origin we pursued the dual purpose. Firstly, we created a sweet product, which would be a source of organic selenium. Therefore the sucrose was replaced with the plant origin sweeteners such as syrup of Jerusalem artichoke and stevioside. Secondly, it was the development of technology and composition of functional food product, intended not only for mass consumption, but also for people suffer from diabetes. It becomes possible due to the absence of sucrose, the presence of selenium and Jerusalem artichoke, which are able to reduce the blood sugar level.
