Mahua (Madhuca longifolia) flowers are boon for the local tribes of India and have been successfully utilized traditionally for the value addition, and are very prone for microbial spoilage. Local folks utilized malpractices of drying which deteriorates the quality attributes of the mahua flowers and ultimately fails to fetch a good price in the market. Present investigation was led to consider the impact of different pre-treatments i.e., blanching time; and dip of potassium meta-bisulfite (KMS) and citric acid (CA) on the physico-chemical and phytochemical potential of dried mahua flowers using response surface methodology (RSM). Maximum physico-chemical and phytochemicals attributes were observed under optimum conditions i.e., a blanching of 4.1 min followed by dipping in solution having 1285 ppm KMS and 0.77% citric acid. Qualitative analysis through Fourier transform infrared spectroscopy (FTIR) supported the findings. Sugar and phytochemical profiling by high performance liquid chromatography (HPLC) proved the significant effect of each variable. No specific cluster formation was observed during cluster analysis of whole data indicating the significant and equal effect of all variable on the quality of dried mahua flowers. The optimized conditions will definitely help the local processors as well as the industrialist to maintain the quality attributes of the dried mahua.

预干燥处理对干燥麻花花理化和植物化学潜力的影响

Mahua (Madhuca longifolia) 花是印度当地部落的福音，传统上已成功用于增值，并且很容易受到微生物腐败的影响。当地人利用干燥的不当做法，降低了麻花的品质，最终未能在市场上卖个好价钱。目前的调查是为了考虑不同预处理的影响，即热烫时间；使用响应面法 (RSM) 研究偏亚硫酸氢钾 (KMS) 和柠檬酸 (CA) 对干麻花的理化和植物化学潜力的影响。在最佳条件下观察到最大的物理化学和植物化学特性，即热烫 4.1 分钟，然后浸入具有 1285 ppm KMS 和 0.77% 柠檬酸的溶液中。通过傅里叶变换红外光谱 (FTIR) 进行的定性分析支持了这些发现。通过高效液相色谱 (HPLC) 进行的糖和植物化学分析证明了每个变量的显着影响。在整个数据的聚类分析过程中没有观察到特定的聚类形成，表明所有变量对干麻花质量的影响显着且相等。优化的条件肯定有助于当地加工商和实业家保持干麻花的质量属性。在整个数据的聚类分析过程中没有观察到特定的聚类形成，表明所有变量对干麻花质量的影响显着且相等。优化的条件肯定有助于当地加工商和实业家保持干麻花的质量属性。在整个数据的聚类分析过程中没有观察到特定的聚类形成，表明所有变量对干麻花质量的影响显着且相等。优化的条件肯定有助于当地加工商和实业家保持干麻花的质量属性。
