Abstract
Changes in meat sensory quality during storage are difficult to assess accurately and objectively. Advanced analytical technologies for sensory assessment could help predict sensory changes. In this study, vacuum-packed (VP) minced beef was incubated at four different temperatures until the end of its quality shelf-life, before conducting instrumental taste analysis with an Insent electronic tongue and analysis of volatile compounds with headspace SPME GC–MS. It was found that storage time and storage temperature variables explained variation in odour, sourness and umami (adjusted R-squared values of 61 %, 58 % and 63 % respectively), with a relationship identified between sourness and umami tastes and the abundance of volatile compounds (2-butanone, methyl butyrate, methyl valerate and ethyl acetate), and trained panel scores of the odour of beef. The results highlighted that instrumental taste measurements could be used as a potential predictor of sensory shelf-life in vacuum packed beef.
期刊介绍:
The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
