Study on the Efficient Preparation Technology of Instant Freeze-Dried Powder of Anoectochilus roxburghii
Objective:To optimize the extraction process of Anoectochilus roxburghii,aiming at improving the dissolution rate of active components and preparing high-quality instant freeze-dried powder.Method:By adopting the water extraction technology with pulp breaking and wall-breaking,combined with the response surface optimization design method,the extraction conditions such as solid-liquid ratio,pulp breaking temperature,and pulp breaking time were systematically optimized.Finally,the instant freeze-dried powder of Anoectochilus roxburghii was prepared through processes such as concentration,purification,and freeze-drying.Result:The optimal extraction process parameters were as follows solid-liquid ratio of 1 to 34(g to mL),pulp breaking temperature of 100℃,pulp breaking time of 5 minutes,with two extractions.Under these conditions,the yields of soluble solids,crude polysaccharides,and freeze-dried powder in the prepared instant freeze-dried powder of Anoectochilus roxburghii were significantly improved.The product appeared as brownish-yellow fine powder,dissolved rapidly,and the solution was clear and transparent,exhibiting excellent quality characteristics.Conclusion:The optimized extraction process significantly increased the yields of soluble solids,crude polysaccharides,and freeze-dried powder in Anoectochilus roxburghii,providing a solid scientific basis for the diversified application and market promotion of Anoectochilus roxburghii in fields such as food and health products,and promoting the high-quality development of the Anoectochilus roxburghii industry.
