A Review of Technologies for Freshness Detection of Meat and Meat Products

Meat and meat products are prone to deterioration during storage and transportation, resulting in the formation of substances harmful to human health, so monitoring their freshness is particularly critical to ensure the quality and safety of meat products. Traditional methods used to evaluate meat freshness mainly include sensory, physicochemical and microbial analyses. With the continuous development of food quality detection technology, a variety of novel technologies for meat freshness detection have emerged, such as sensory bionic technology and spectroscopy. This paper reviews the technologies for freshness detection of meat and meat products, and discusses their advantages and disadvantages. Furthermore, it provides an outlook on future research and developments. This review provides a reliable theoretical basis for future research and development.
