Annotation:
Search, evaluation and application of natural antioxidants and other bioactive phytochemicals has become one of the most popular topics among food, agricultural and nutritional scientists due to the increasing evidence of health effects of numerous plant origin natural compounds. In recent years search for effective extraction and fractionation methods, which would allow to employ whole plant material without generating any waste (such complex processes are called biorefining or in some cases agrorefining), became one of the most important gals. In this study various schemes of biorefining using high pressure extraction methods was investigated and obtained results may be used for the up-scaling the production of functional ingredients from selected plants to industrial level.
