Ultrasonic-Assisted Extraction Process of Polysaccharide from Morinda Fruit
Dry powder of Morinda fruit was selected as the raw material to determine the gross extraction of polysaccharide by optimize ultrasonic-assisted extraction process of polysaccharide from Morinda fruit.To determine the extraction rate of polysaccharide in Morinda fruit,main technological parameters like ultrasonic treating time,treating temperature,treating power and solid-liquid ratio,were investigated by a single factor method coupled with L9(34) orthogonal array design.The results showed that the optimal conditions of extracting polysaccharide from Morinda fruit was a two-step extract with Morinda fruit powder size of 60,solid-to-liquid ratio of 1:25,ultrasonic power 300 W,extracting 45 min at a temperature of 70 ℃.The verification test was carried out based on an orthogonal experiment,it was proved that this extracting technology was efficient,the result provided theoretical parameters for the practical production of the extraction of Morinda fruit polysaccharide.
