Influence of extraction and processing technology on content of bioactive compounds in foods of plant origin

Demand for natural product developments continues to grow, and the applications of natural ingredients in the processing industry, either as pure compounds or as standardized extracts, could be considered as value-added food ingredients. Therefore, the chioce of appropriater extraction procedure for biologically active compounds (BACs) isolation is the key step to obtain high quality extract. Due to great structural diversity and desired physical/chemical properties of the BACs, extraction from the plant matrices can be challenging task. Hence, it is of great importance to identify and optimize the most favorable extraction procedure in order to produce high-quality extracts and achieved high yields. Usually, conventional techniques applied for solvent extraction (CE) is the most commonly used standard extraction method for this purpose. However, innovative extraction techniques such as pressurized liquid extraction (PLE), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), high-pressure assisted extraction (HPAE), cold plasma-assisted extraction (CPAE) etc. are commonly used for the BACs extractions. In comparison to CE, aforementioned techniques have tendency to improve extraction yield, enhance the quality of extract, shorten extraction time followed by significant energy costs, and to reduce the solvent consumption. Recent findings demonstrate that each extraction procedure could promote the recovery of specific BACs subclasses with different efficiencies, therefore the use of more than one extraction procedure is required to determine the phytochemical profile of a plant. Due to all chemical or physical limitations of any extraction, the choice of the adequate procedure for each kind compounds must be considered and optimized in order to obtained extracts with higher yield and target profile of BACs.
