Soybean sprouts, a nutritional food product, can contribute to food security because they can be grown within a week and do not require sophisticated technology. The yield and quality of soybean sprouts are influenced by various factors, including seed priming and growing conditions. The objective of this study was to investigate the effects of seed soaking in different concentrations of illite, a clay mineral, on the yield and quality of soybean sprouts. Soybean seeds soaked in five concentrations (0.5%, 1%, 3%, 5%, and 10%, w/v) of illite or tap water for 8 h were named IP-0.5, IP-1, IP3, IP-5, IP-10, and control, respectively. The highest sprout yield was found in IP-3, followed by IP-1, and IP-5, which had 11.1%, 8.8%, and 7.4% increments, respectively, compared to the control. The content of vitamin C, mineral element, isoflavone, total polyphenol, and total flavonoid was higher in many of the illite-treated soybean sprouts than in the control. The overall results indicated that pre-soaking soybean seeds in lower concentrations (0.5−3%, w/v) of illite could be helpful to enhance the yield and nutritional value of soybean sprouts in an easy and inexpensive way.

“…Furthermore, zinc may also interfere with other cellular mechanisms such as signaling and gene regulation [32]. Zinc's wide range of anti-infectious abilities has subsequently led to the use of this mineral in various applications that requires contamination and infection control [33,34]. Our study sought to test whether zinc addition can provide a solution to the microbial contaminations that are frequently emerging in the dairy industry.…”

Dairy products are a sector heavily impacted by food loss, often due to bacterial contaminations. A major source of contamination is associated with the formation of biofilms by bacterial species adopted to proliferate in milk production environment and onto the surfaces of milk processing equipment. Bacterial cells within the biofilm are characterized by increased resistance to unfavorable environmental conditions and antimicrobial agents. Members of the Bacillus genus are the most commonly found spoilage microorganisms in the dairy environment. It appears that physiological behavior of these species is somehow depended on the availability of bivalent cations in the environment. One of the important cations that may affect the bacterial physiology as well as survivability are Zn2+ ions. Thus, the aim of this study was to examine the antimicrobial effect of Zn2+ ions, intending to elucidate the potential of a zinc-based antibacterial treatment suitable for the dairy industry. The antimicrobial effect of different doses of ZnCl2 was assessed microscopically. In addition, expression of biofilm related genes was evaluated using RT-PCR. Analysis of survival rates following heat treatment was conducted in order to exemplify a possible applicative use of Zn2+ ions. Addition of zinc efficiently inhibited biofilm formation by B. subtilis and further disrupted the biofilm bundles. Expression of matrix related genes was found to be notably downregulated. Microscopic evaluation showed that cell elongation was withheld when cells were grown in the presence of zinc. Finally, B. cereus and B. subtilis cells were more susceptible to heat treatment after being exposed to Zn2+ ions. It is believed that an anti-biofilm activity, expressed in downregulation of genes involved in construction of the extracellular matrix, would account for the higher sensitivity of bacteria during heat pasteurization. Consequently, we suggest that Zn2+ ions can be of used as an effective antimicrobial treatment in various applications in the dairy industry, targeting both biofilms and vegetative bacterial cells.

The technology of controlled germination as a result of radio stimulation of wheat grains of the soft spring variety L-503 allowed to establish optimal stimulating doses ranging from 9 Gy to 13 Gy of radiation. As a result of the study, it was found that the use of optimal radiation doses provides high germination energy after 3 days as a result of a decrease in the permeability of membranes for water as a medium for germination, with a germination rate of 95.7-97.0% of wheat grains and fully corresponding to the germination ability after 5 days with a germination rate of 96.6-97%, germinated grains wheat is distinguished by strong seedlings up to 1.9 mm long. When used for germination of wheat grains, 7 days after their treatment with radiation, the prolonged effect of small doses of a stimulating nature is provided in comparison with non-irradiated samples and, providing high germination of wheat, differ in lower quantitative indicators: by 0.5-0.7% for grains treated with doses of 1-4 Gy, by 0.9-1.2% and by 1.0-1.7% for grains treated with doses of 5-8 Gy and 9-13 Gy, respectively. The germination of grains treated with doses from 14 Gy to 20 Gy decreased by 2.4-3.2%. On the 5th day after germination of wheat grains treated with small doses of radiation, a more intense increase in the amino acid score of amino acids (ACS) is observed compared to untreated samples during the same germination period. The AKS of amino acids in experimental wheat samples treated with radiation dose of 9-13 Gy increased from 0.64% for isoleucine to 8.25% for lysine. Limiting amino acids -lysine and threonine -have been established. The best indicators of biological value are those treated with optimal radiation doses of wheat grains during germination for up to five days. The study of microbial contamination (microorganisms, fungal microbiota) of the grain surface shows a supportive antimicrobial effect. To regulate the mechanism of enzymatic activity of proteases in wheat grain after treatment with small doses of radiation, which affect the energy and germination ability of wheat grains, it is necessary to consistently continue research.
