Special Issue Information

Dear Colleagues,

The demand for more convenient and varied meat products, faster production rates, improved quality and longer shelf lives has grown exponentially. This, together with the severity of traditional meat processing technologies, are driving forces for improving and developing new meat preservation technologies. Therefore, there have been many technological developments in unit operations such as pasteurization, sterilization, cooking and drying, and currently, the new technological approaches for meat preservation are seriously likely to replace traditional, well-established preservation processes. Most of these technologies are localized and clean and therefore appear to be more environmentally friendly than traditional ones. Novel processing technologies will attract more attention from meat processors once they can provide better-quality meat products with more added value, along with a reduced environmental footprint and processing costs.

Both SNAC and NaNO2 demonstrated pH-responsive antibacterial activity, with SNAC showing greater efficacy than NaNO2 (p [...] Read more.
This study investigated the antibacterial effects of S-nitroso-N-acetylcysteine (SNAC) and sodium nitrite (NaNO2) against Escherichia coli and their application in beef sausages. Both SNAC and NaNO2 demonstrated pH-responsive antibacterial activity, with SNAC showing greater efficacy than NaNO2 (p < 0.05) at the same pH (3, 5, and 7). The reactive oxygen species (ROS) and reactive nitrogen species (RNS) induced in E. coli by SNAC were significantly higher than those induced by NaNO2 (p < 0.05), and both ROS and RNS values increased as the pH decreased. In addition, a lower pH led to more pores on the E. coli cell surface and increased membrane permeability, resulting in a more pronounced inhibitory effect. When applied to a beef sausage, SNAC-treated sausages had significantly lower total colony counts and carbonyl content compared to NaNO2-treated ones (p < 0.05). Consequently, SNAC shows great potential as a replacement for NaNO2 in meat products. Full article
