摘要
Summer savory (Satureja hortensis L.), Lamiaceae family, was used in folk medicine and food industry, and the resulting essential oil was used to flavor various food products, as well as a biologically active substance in cosmetics. The aim of the present work was the determination of the physicochemical parameters surfase tension and density of summer savory essential oil, obtained by steam distillation under industrial conditions, at four different temperatures 10, 20, 30 and 40°C. The temperature dependence of the two physicochemical parameters shows that the values for density were in the range of 0.921 g/cm3 at 10°C to 0.898 g/cm3 at 40°C, and for surface tension from 31.68 mN/m at 10°C to 27.51 mN/m at 40°C, respectively. The antioxidant activity was also determined on the summer savory essential oil by four methods DPPH (0.50 mM TE/mL), FRAP (1.23 mM TE/mL), ABTS (0.54 mM TE/mL), and CUPRAC (2.91 mM TE/mL). The investigation of these parameters and properties were a prerequisite for further studies on the application of summer savory essential oil in various food products.

Lamiaceae家族的Summer Savory（Sateryja Hortensis L.）用于民间医学和食品工业，由此产生的精油用于调味各种食品，以及化妆品中的生物活性物质。本工作的目的是确定物理化学参数表面表面张力和夏季美味精油的密度，在工业条件下，在四个不同温度下，在10、20、30、30和40°C下通过蒸汽蒸馏获得。两个物理化学参数的温度依赖性表明，在40°C下，密度的值在10°C至0.898 g/cm3的范围内，在10°C时的表面张力范围为0.898 g/cm3在40°C下分别为27.51 mn/m。还通过四种方法（0.50毫米TE/mL），FRAP（1.23 mm TE/ml），ABT（0.54 mm TE/ml）和Cuprac（2.91毫米TE/ML）在夏季美味精油上确定抗氧化活性）。对这些参数和特性的研究是进一步研究夏季咸味精油在各种食品中应用的先决条件。
