Meat Technology and Packaging

Course content

The main objective of the course is to educate students in processes associated with slaughtering, fresh and meat product processing, storage and packaging. In addition, a sound background will be provided in what constitutes 'meat quality', both from the producers and consumers point of view and which factors affect to the final quality.

 

The course will provide knowledge of how the slaughter process affects end-product quality in order to be able to produce high-quality meat products in a continuously changing industry with changing consumer preferences.

 

The course emphasis is on aspects of factors in meat production chain that affect end-product quality, including meat technology elements such as slaughter and pre- and post-slaughter handling, as well as carcass chilling and classification. The course will also focus on aspects related to meat processing techniques, such as cooking or chilling of meat, and the use of additives and ingredients, as well as further utilization of meat by-products.

 

  • The course also includes general information about packaging of fresh meat, especially how different atmospheres (air, gas mixtures, vacuum, etc.) surrounding the meat can influence quality attributes, including protection of meat and meat products from undesirable impacts on quality. Material properties, intelligent packaging and active packaging will also be mentioned.

 

The course will provide students with an understanding of principal quality attributes of meat, including texture/tenderness, water-holding capacity and color, including how quality is defined and measured. Variations in fresh meat quality with substantial implications in subsequent industrial processing of meat will be examined. The course provides a background to understand the technological basis of how meat quality is understood and controlled to provide optimal high quality meat products.

 

The course will be of benefit for all food science students aiming at a detailed understanding of meat technology and processing, and this insight will be used in relation to innovation and development of novel meat based foods.
