  • A new sake fermented using a mixture of Aspergillus sp., Rhizopus sp. and yeast (Saccharomyces cerevisiae) containing allbanggae was developed in this study. The effects of the allbanggae contents ($0{\sim}50%$) in the sake on the qualitative and sensory properties and flavor components were investigated. The fermentation with allbanggae, especially in sake containing 10% allbanggae, showed the highest level of alcohol ($15.3{\sim}16.4%$), whereas the amount of alcohol decreased with increasing allbanggae contents. Amino acidity in sake containing 10% and 20% allbanggae indicated the highest levels ($0.90{\sim}1.20%$). In addition, it was observed that the sake containing 10% allbanggae showed the smallest level of reducing sugars, which were increased with increasing allbanggae ratio. Furthermore, various organic acids in the sake were detected such as citric, succinic, malic and acetic acids, among which the acetic acid showed the highest amount ($160.3{\pm}8.0{\sim}253.3{\pm}20.3mg/100mL$). The major amino acids detected in the sakes were alanine, proline, histidine, phenylalanine, lysine and glutamic acid. The sake containing 20% allbanggae indicated the highest amino acids amount among the allbanggae ratios. Based on these results, it was concluded that the sake containing 20% allbanggae could be successfully commercialized.

  • In this study, we prepared naproxen (NP) imprinted biodegradable polymer based multi-layer biomaterials using allbanggae starch (ABS), polyvinyl alcohol (PVA), and alginic acid (SA), and investigated their physicochemical properties and the controlled drug release effects. In addition, the prepared multi-layer biomaterials were characterized by FE-SEM and FT-IR. In order to confirm the controlled drug release effect for the transdermal drug delivery system (TDDS), the NP release properties of NP imprinted multi-layer biomaterials were investigated using various pH buffer solutions and artificial skin at 36.5 ℃. The results of NP release in various pH buffer solutions indicated that the NP release at high pH was about 1.3 times faster than that at low pH. In addition, NP release in multi-layer biomaterials was about 4.0 times slower than that in single-layer biomaterials. It was confirmed that the NP release rate in triple-layer biomaterials was 4.0 times slower than that in single-layer biomaterials while using artificial skin. Also, it could be found that NP in double-layer biomaterials and triple-layer biomaterials was released sustainably for 12 h. The NP release mechanism in pH buffer solutions followed the Fickian diffusion mechanism, but followed the non-Fickian diffusion mechanism with artificial skin.
