Food and Machinery

In this study, color, cooking loss, water holding capacity, water-loss rate, pH value, amino acid and fatty acid composition of raw meat were investigated during storage （0, 1, 2, 4, 8 weeks） at -18 ℃. The results indicated that water-loss rate and cooking loss of meat increased as the storage time increased, and water holding capacity of meat decreased with the increasing storage time （P<0.05）. The contents of lysine, alanine and cysteine increased with the increasing storage time. The amounts of saturated fatty acids increased obviously, while polyunsaturated fatty acids contents decreased with the increasing storage time. Therefore, although frozen storage is an ideal method for meat storage. However, the nutritive value of raw meat will change, leading to the decline of meat quality.

Digital Urban Agriculture As Disparate Development: The Future Of Food In Three U.S. Cities Through The Lens Of Stakeholder Perceptions, Networks, And Resource Flows, Michael Carolan

William & Mary Environmental Law and Policy Review

Urban agriculture takes many forms. Often, the term elicits images of raised beds, hoop houses, and, in those instances where topsoil is both present and non-contaminated, in-ground gardens—what I call traditional urban agriculture (“TUA”). But that imagery is changing, especially in some parts of the country where vacant space is scarce and land prices dear. In those instances, cities are seeing growth in digital urban agriculture (“DUA”). DUA, as defined here, refers to farming within urban and peri-urban areas that incorporates elements of automation, software, and/or silicon-based hardware into their operations. While this definition is not meant to draw a …
