不同提取工艺参数对苦杏仁水(蒸馏液)氢氰酸含量的影响研究及应用思考OA

Objective:To explore the effetcs of different extraction process parameters on the hydrocyanic acid content in bitter almond water(distillate)and provide a reference for Chinese materia medica production enterprises.Methods:Equal amounts of bitter almonds were respectively soaked for 24 hours under various experimental conditions(soaking temperature 25-85℃,crushing status,wrap-boiling,and increased soaking water volume),and then dis-tilled for extraction.The bitter almond water(distillate)was collected and the hydrocyanic acid content was detec-ted.The relationship between the experimental conditions and the content was analyzed and discussed.Results:Soa-king at 55℃for 24 hours,the content of hydrocyanic acid in the bitter almond water(distillate)was the highest(P<0.05).At the soaking temperature of 55℃,there was no significant difference(P≥0.05)in the hydrocyanic acid content of the bitter almond water(distillate)between crushed and unbroken bitter almonds.The 120-mesh non-woven fabric wrapped bitter al-monds for soaking and distillation extraction showed no significant difference(P≥0.05)in the content of hydrocyanic acid in the bitter almond water(distillate)compared with that without wrapping.When the soaking water volume was increased from 1.6 times the amount of medicinal materials to 4 times,there was no significant difference(P≥0.05)in the content of hydro-cyanic acid in the bitter almond water(distillate).Conclusion:The soaking temperature has a significant impact on the hydro-cyanic acid content of bitter almond water(distillate),and 55℃is the optimal soaking temperature.The breakage of bitter al-monds(whether they are broken or not),wrap-boiling condition(Wrapped in 120-mesh non-woven fabric),and the increase in soaking water(from 1.6 times the amount of medicinal materials to 4 times)have no effect on the hydrocyanic acid content of bitter almond water(distillate).The above research results can provide references for Chinese materia medica production en-terprises.
