Pengaruh Asam Fumarat-Natrium Bikarbonat terhadap Kualitas Granul Effervescent Tej Hijau Secara Granulasi Kering (The Effect of Fumaric Acid-Sodium Bicarbonate on the Green Tea Effer vescent Granule's Quality Made by Dry Granulation)
Tea plant (Camellia sinensis L.) had been known to contains epigallocathecin gallate (EGCG) that can be used to maintain the healthy. In this research, the green tea was tried to be formulated in effervescent dosage form, with the focus on the effect among fumaric acid, sodium bicarbonate, and the interaction between fumaric acid and sodium bicarbonate on the green tea extract effervescent granule's physical properties, that made by dry granulation method. Physical properties of effervescent granule that been study were moisture content, flow rate, disintegration time, and pH of the solution. The result showed that sodium bicarbonate was dominant in determining pH, granule flow rate and moisture content of granule, whereas fumaric acid dominant in disintegration time of effervescent granule.
