  • Title: Effect of some essential oils on rheological properties of wheat flour dough.
    Author: Ozcan MM.
    Journal: Int J Food Sci Nutr; 2009 Mar; 60(2):176-81. PubMed ID: 18608558.
    Abstract:
    The effects of summer savory (Satureja hortensis L.), majorana (Origanum vulgare L.), sage (Salvia triloba L), rosemary (Rosmarinus officinalis L.), pickling herb (Echinophora tenuifolia L.) and laurel (Laurus nobilis L.) essential oils on extensograph and farinograph characteristics of wheat flour doughs were determined. Also, some chemical properties (moisture content, ash content, wet gluten content, sedimentation value and falling number) were established. The results show that resistance to extension, maximum resistance, ratio number (minimum) and ratio number (maximum) values were increased by S. hortensis oil addition during the proving time. Extensibility values of S. hortensis, O. vulgare and S. triloba at 90 min of proving time were found lower that than those of other proving times (except S. triloba at 135 min). According to the extensograph results, rosemary, pickling herb and laurel oils allowed higher extensibility and energy, and lower resistance to extension and maximum resistance (Brabender Unit Line). The farinograph water absorption (500 farinograph units) varied from 63.6 to 64.7. The development time of dough with rosemary oil was the same as the control group. Stabilities of dough with savory sater, majorana and sage oil were found lower that those of both control and other oils. As a result, rosemary, pickling herb and laurel oils had an advantage on the extensograph and farinograph characteristics of wheat flour dough.
