Streszczenie:

Sodium nitrate is an essential food additive widely used in cured meats. The increased unfavorable perceptions about chemicals in foods and their repercussions on health have positioned the nitrite as undesirable compound in meat products. Natural and organic ingredients have taken an important place within the consumer preferences. Here, obtaining nitrite from natural source was achieved using nitrate-reducing bacteria Staphylococcus carnosus and S. xylosus. The strains pre-incubation into the celery-based medium allowed the stimulation of nitrate reductase activity. The increased values of s

Nitrates and nitrites have been traditionally used as curing agents in the production of cured meat products. Beneficial effects of the addition of nitrates and nitrites to meat products are the improvement of quality characteristics as well as the microbiological safety. The nitrates and nitrites are mainly responsible for the development of the distinct flavor, the stability of the red color, as well as the protection against lipid oxidation in cured meat products. The nitrites show important bacteriostatic and bacteriocidal activity against several spoilage bacteria as well as foodborne pat

The consumption of animal products, including meat and meat products, has increased globally with increased household income. Spoilage by microbes, autolytic enzymes, and lipid oxidation can cause the deterioration of meat and meat products, which has a considerable economic and environmental impact. Meat curing, which includes the addition of salt, nitrite, and sometimes nitrate to fresh meat cuts, enables a preservative effect by removing moisture and reducing the water activity of the meat.

Capacitance dilatometry was used to measure the relative thermal expansivity, ΔL/L0, of single crystals of sodium nitrate (NaNO3) as a function of temperature. From these measurements, the phase transition at Tf = 550 K shows characteristics of a discontinuous transition. A theory based on the competition between long-range interactions and the entropy gained by rotating NO3 groups at high temperatures predicts a discontinuous transition at T = Tf with ΔL/L0 ∼ (Tf T)ζ with ζ = 1.

This study assessed the spatial variation in physico-chemical properties of sediment along Epie creek, Niger Delta, Nigeria. Samples of the sediment were collected in triplicates from 5 different location along Epie creek using sediment grab. The samples were processed and analyzed using standard analytical methodology. Results revealed that the characteristics  of the creek ranged from 6.67 – 6.77 (pH), 435.17 – 1189.50 µhmoscm<sup>-1 </sup>(conductivity), 0.39 – 1.05mg/kg (nitrite), 2.87<sup> </sup>– 7.59 mg/kg (nitrate), 1.06 – 3.81 mg

Zr-based metallic glasses (MGs) are promising materials for mold manufacturing due to their unique mechanical and chemical properties. However, the high hardness of metallic glasses and their tendency to crystallize at high temperatures make it challenging to fabricate precise and smooth microscale structures on metallic glasses. This limitation hampers the development of metallic glasses as molds. Jet electrochemical machining (jet-ECM) is a non-contact subtractive manufacturing technology that utilizes a high-speed electrolyte to partially remove material from workpieces, making it highly su
