For years, high-pressure processing has been viewed as useful for pasteurizing food while maintaining the quality of fresh food. However, even at moderate pressure, this process is not without effects on food, especially on meat products. These effects are especially important because pressure greater than 400 MPa is generally necessary to achieve efficient microbial inactivation. In this review, recent advances in the understanding of the impacts of high pressure on the overall quality of raw and processed meat are discussed. Many factors, including meat product formulation and processing parameters, can influence the efficiency of high pressure in pasteurizing meat products. It appears that new strategies are applied either (i) to improve the microbial inactivation that results from high pressure while minimizing the adverse effects of high pressure on meat quality or (ii) to take advantage of changes in meat attributes under high pressure. Most of the time, multiple preservation factors or techniques are combined to produce safe, stable, and high-quality food products. Among the new applications of high-pressure techniques for meat and meat-derivative products are their use in combination with temperature manipulation to texturize and pasteurize new meat products simultaneously.
Currently, there is major consumer concern about dietary salt intake worldwide. However, even with the development of contemporary preservation practices, sodium chloride is still essential in processed meat products. Despite a long history of use, salt is now seriously controversial in food due to health concerns that are mostly related to high blood pressure and cardiovascular risks. Changes in meat processing methods have reduced those potential risks, but different perceptions continue to shape how consumers and society view dietary salt. The current consumer demand for additive‐free food, such as the clean‐label movement, has renewed consumer willingness for naturalness in food products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
