Nitip disini dulu, hehe
A study on formulation of chewable lozenges containing extract of ginger plants (Zingiber officinale Rosc.) that has previously been introduced by mycorrhizal fungi arbuskula has been conducted. The purpose of this study is to investigate the influence of concentration ratios of gelatin and glycerin as the base on the physical properties of chewable lozenges and on the preference responses or acceptance of respondents. Chewable lozenges were made of three formulas by varying the concentration ratio of gelatin and glycerin, they were Formula I (15%:75%), Formula II (20%:70%), and Formula III (25%:65%). The physical properties of lozenges were evaluated, included the color of the product, brightness, surface texture, physical appereance, consistency, and dissolving time. Results showed that the combination of gelatin and glycerin affected the physical properties of the lozenges. The increase in concentration of gelatin and the decrease in concentration of glycerin resulted in a decrease in brightness, the roughness of surface texture, the increase in consistency, and the increase in dissolving time (Sig. 0,05). Results of consumer preference test performed on 20 respondents showed that Formula II was the most acceptable.
