The present invention is an innovative technology that utilizes natural raw materials such as germinated
black rice, black beans,
aronia, and blueberries to extract anthocyanins, which are functional physiologically active substances, with higher efficiency and superior quality compared to existing methods. Specifically, it is a method that maximizes the extraction efficiency of
anthocyanin components by maximizing the contact frequency and surface area between the
raw material and the extraction
solvent through fluid
bed technology or a stirring
system under low-temperature conditions (approximately 25β). The core technology of the present invention lies in maximizing the
anthocyanin content by optimizing the management conditions of the
raw material during the
germination process, and precisely controlling low-temperature
erosion to minimize
thermal damage or loss of activity of
anthocyanin components caused by high temperatures during the extraction process. Furthermore, the present invention efficiently extracts anthocyanins of high purity and yield by applying process devices such as a
fluidized bed or a stirring
system to significantly increase the contact frequency and contact surface area between the
raw material and the
solvent. In particular, the present invention aims to significantly improve long-term storage stability and
bioavailability by applying additional
filtration and
nanoparticle-based stabilization technology after extraction at low temperature to increase the uniformity of microparticles in the extract, and by effectively protecting anthocyanin components from external environmental factors through liposomes,
solid lipid nanoparticles (SLN), or
polymer encapsulation technology. In addition, the main purpose of the method of the present invention is to minimize the degradation and alteration of anthocyanin components to enhance their quality and economic value as functional materials, thereby increasing their
usability so that they can be widely applied in various industrial fields such as food,
cosmetics, and pharmaceuticals.
