Valorization Of Carrot Processing Waste, Alexandra M. Duval

Master's Theses

Commercial carrot processors produce up to 175,000 tons of carrot waste annually. Carrot Mash (CM) is the term referring to the waste by-product of peeled baby carrot processing. Transportation of carrot processing waste is expensive due to its high- water content (approx. 83-95%). High in bioactive compounds (carotenoids) and dietary fibers, it is expected that its conversion into a value-added by-product is of interest to the carrot processing industry. Hemicellulose-rich plant materials have proven to be a source of oligosaccharides, which are known for their beneficial prebiotic activity. The objectives of this research were to: 1) determine the effect of …

Central Performance Testing: Purpose, Benefits, Impacts, And Trends, Terry A. Gipson

Professional Agricultural Workers Journal

Abstract The premise of the central performance test is that differences in performance of young animals raised in a common environment are largely attributed to genetics; however, this can be confounded by differences in pre-test environments. It is assumed top-ranking individual’s genetic advantage is a permanent change transferable to the next generation. The popularity of the central performance tests has waxed and waned over the past decades. A strengths-weaknesses-opportunities-threats analysis indicates factors influencing producer participation can include cost, time, geographical coverage, alignment with industry, association support, and relevancy. A second generation of central performance tests with innovative, targeted approaches is …
