Abstract

Abstract Effect of enzymatic pretreatment before hydrodistillation process on yield and composition of Rosmarinus officinalis essential oil was studied. Results obtained by using two selected commercial enzymes applied in food and beverage industry were compared. Control process with non-enzymatic pretreatment in analogous conditions was also performed for proper interpretation of results. Application of gas chromatography with mass selective detector (GC-MS) enabled analysis and comparison of essential oils composition. Moreover, total phenolic content (TPC) was determined spectrophotometrically in post-processing hydrolates, which are also valuable products e.g. for cosmetic applications. Modifications of isolation process by pretreatment with selected enzymes resulted in significant increase in essential oil yields in comparison to conventional hydrodistillation and control process with non-enzymatic pretreatment in analogous conditions. No substantial changes in the composition of obtained essential oils were observed. In post-processing hydrolates higher values of total phenolic content (TPC) were found both after enzymatic and non-enzymatic pretreatment.

酶法预处理对迷迭香精油产率及化学成分的影响

摘要研究了加氢蒸馏前酶解预处理对迷迭香精油收率和成分的影响。对食品饮料工业中所选用的两种酶进行了比较。在类似的条件下进行了非酶预处理的控制过程，以正确解释结果。气相色谱-质谱联用技术(GC-MS)的应用使精油成分分析和比较成为可能。此外，分光光度法测定了后处理水合物中的总酚含量(TPC)，这也是化妆品应用等有价值的产品。与传统的加氢蒸馏和在类似条件下采用非酶预处理的控制工艺相比，采用选定的酶预处理对分离工艺进行修改，可显著提高精油得率。所获得的精油的组成没有实质性的变化。在后处理水解产物中，经酶处理和非酶处理的总酚含量(TPC)均较高。
