正交试验优选石榴皮最佳炮制工艺研究OA

This study aimed to optimize the frying process of pomegranate peel with auxiliary materials to increase the content of its bioactive components,providing a scientific basis for standardizing the processing of pomegranate peel.Preliminary experiments were conducted to compare three common frying methods:plain frying,soil frying,and bran frying,using the contents of total gallic acid and ellagic acid as the main evaluation indicators.The results preliminarily identified bran frying as the optimal method for pomegranate peel.Subsequently,to further optimize the bran frying process,an orthogonal experimental design was adopted,with processing time(A)and wheat bran dosage(B)as the key variables,each set at three levels.The contents of total gallic acid and ellagic acid in the processed pomegranate peel were used as evaluation indices,and the process parameters were analyzed and optimized using a comprehensive scoring method.The results showed that both processing time and wheat bran dosage significantly influenced the content of target components in pomegranate peel.Based on range analysis and analysis of variance,the order of influence of each factor on the comprehensive score was determined as follows:processing time had a greater impact than wheat bran dosage.The optimal processing conditions were determined to be a processing time of three minutes and a wheat bran dosage of twenty percent.The optimized process is simple,stable,and feasible.It not only helps enhance the material basis for the efficacy of pomegranate peel,but also provides reliable data support and a theoretical foundation for promoting the standardization and normative production of its processing technology.This study holds positive implications for advancing the rational application of pomegranate peel in clinical practice and pharmaceutical preparations.
