Preparation and Quality Characteristics of Ophiopogon japonicus Polysaccharide Chewable Tablets
The main ingredient was the Ophiopogon japonicus tuber,from which Ophiopogon polysaccharides were prepared using a water extraction and alcohol precipitation method.Ophiopogon polysaccharide chewing tablets were prepared by direct powder compression.The chewing tablets were evaluated comprehensively based on sensory scores and texture,and the optimal formulation process for the Ophiopogon polysaccharide chewing tablets was optimized through single-factor experiments and orthogonal experiments.The effects of the addition amounts of Ophiopogon polysaccharide and erythritol,as well as the mass ratio of mannitol to microcrystalline cellulose,on the quality of the Ophiopogon polysaccharide chewing tablets were explored.The results showed that the optimal formulation for the Ophiopogon polysaccharide chewing tablets was an addition of 18％ (mass percentage,the same below)Ophiopogon polysaccharide,a mass ratio of 5∶5 for mannitol to microcrystalline cellulose,and 7.5％ erythritol.Under this formulation,the sensory score of the Ophiopogon polysaccharide chewing tablets was 94.5 points,the compactness was 94 228.74 g·s,the hardness was 14 301.55 g,the DPPH free radical scavenging rate was 42.28％ ,and the ABTS+free radical scavenging rate was 39.33％ .The prepared Ophiopogon polysaccharide chewing tablets had a bright color,a yellowish hue,uniform texture,smooth surface without cracks,Ophiopogon flavor,and certain antioxidant activity.
