Abstract
Food products, such as meat, from grassland production systems have ‘added value’ for both food producers and consumers because of the perceived nutritional value of such products and the environmental acceptability of the production system itself. To differentiate these products from competing products produced without, or with minimal, grass inputs, robust authentication methods are required. This review reports on the application of stable isotope, α-tocopherol stereoisomer and metabolite analyses to authenticate grass-fed beef. The potential for metabolically inert animal tissues to provide an archival record of changes to diet and of urine to yield information, non-invasively, about grass-fed beef production systems is discussed.
