Yield and quality of forage mainly depend on the floristic composition, ie the share of higher quality grasses and legumes, soil fertility, amount and distribution of precipitation and light. Natural meadows and pastures are the most important resource in the forage production in the hilly and mountainous area of Republic of Serbia. Despite the large areas, the forage production on natural grasslands is relatively low. Limited application of a small number of agrotechnical measures is the main reason for low and unstable yields and poor forage quality. Only by appropriate fertilization of meadows and pastures with mineral and organic fertilizers, their rational exploitation, it is possible to achieve an increase in hay yield by several times and improvement in forage quality, simultaneously.
The demand for organic food is rising since consumers want food from reliable, highest quality sources originating from the environment, undisturbed by cultivation and processing. It is necessary to determine to what extent there is a scientific basis for the claims that organic food is of high quality. In this study, beetroot from an organic production system originating from 6 certified organic food producers from different geographic locations was examined. The organic beetroot samples were processed by pasteurization at 700 C and 900 C into beet juice or by drying at 550 C. The following samples were tested and compared: fresh beetroot, pasteurized beet juice and dried beetroot slices. The concentration of vitamin C, level of total phenol compounds (TPC) and antioxidative activity (TAA) in beetroot were influenced by the geographic origin and the applied processing method. The highest degradation for all analysed parameters was found in the samples treated by drying or pasteurisation at 90ºC. The lowest losses of studied phytochemical components were observed during juice pasteurisation at 700C. The correlation coefficient between TPC and TAA was high and significant (r2 = 0.966).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
