Abstract
Porosity variations have an impact on the disintegration behavior of tablets whereas the influence on the disintegration characteristics of natural plant product (NPP) tablets has not been extensively studied. Revealing the pore structure of NPP tablets provides a new and important clue to elucidate the phenomenal behavior and underlying mechanisms of tablet disintegration. In this study, the effect of porosity variation on disintegration of NPP tablets was evaluated for the first time. The disintegration performance of NPP tablets was evaluated using tablet attributes, disintegration kinetics, and the wicking process. Mercury intrusion porosimetry (MIP) and X-ray computed microtomography (XμCT) were used to characterize the microstructure of the tablets. Curcuma Longa Linn. extractions were compacted into tablets with different solid fractions. Tablet qualities changed significantly with increasing porosity. An increase in the wicking rate with porosity changed by visualizing the wicking process. The disintegration kinetics of tablets showed a sensitive variation after an increase in porosity. The pore structure of tablets including parameters such as pore size distribution, tortuosity, and connectivity were identified as direct drivers of wicking and disintegration. The current study provides new insights into the disintegration mechanism of dissolved NPP tablets by exploring the evolution of the pore microstructure.
期刊介绍：
The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide.
The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them.
Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
