Process Optimization and Moulding of Polygonatum sibiricum and Rubus chingii Paste
In order to promote the development and application of Chinese medicinal herbs with the same source of food and medicine in the nutritional food industry,the active ingredients and nutrients of Chinese medicinal herbs are applied to food preparation in the form of common food products,combined with modern food science and technology.Two Chinese medicinal herbs,nine-formulated Polygonatum sibiricum and Rubus chingii,were used as raw materials,and the extraction process was optimized through one-way and Box-Benhnken central combination experimental design,and the moulding process of this Chinese herbal paste was determined through sensory evaluation.The optimization results showed that the optimal conditions for the extraction of nine-formulated P.sibiricum were:material-liquid ratio 1∶14,extraction temperature 92 ℃,extraction time 1.5 h.The polysaccharide content of the extract obtained under these conditions was(4.376±0.307)％,and the rate of the paste obtained was(40.610±0.318)％.The optimal conditions for the extraction of R.chingii were:material-liquid ratio 1∶12,extraction temperature 97 ℃,extraction time 3.5 h.The content of ellagic acid in the extract was(47.07±3.23)µg/mL,and the content of Kaempferol 3-O-Rutinoside was(8.97±0.04)μg/mL,and the rate of the paste was(15.98±0.49)％.The optimal conditions for the moulding of paste were 6∶1 for the mass ratio of nine-formulated P.sibiricum and R.chingii,and the moisture content was 28％-30％through the organoleptic evaluation.
