Given the phytochem. properties of Dracocephalum kotschyi, this research considers the effects of adding its essential oil to cupcakes and investigation of the its oil oxidative stability. At first D. kotschyi’s essential oil (DKEO) is identified and measured by GC/MS. The results show that the most important components of DKEO are α-pinene (25.50%), geranial (14.01%), limonene (12.39%), and neral (11.07%). Chem. analyses on pH, acidity, peroxide value, p-Anisidine value, and total oxidation value (TOTOX) show that increasing the concentration of DKEO reduces the oxidation rate and increases the oxidative stability of the cupcake’s oil during storage. Sensory evaluation shows that DKEO used concentration does not have favorable effects on some organoleptic properties of cupcakes. Despite the pos. effects of DKEO on maintaining the oxidative stability of cupcake’s oil during baking and storage, lower concentrations of it are recommended, along with combinatory usages of this essential oil with other commonly used essential oils in the confectionery industry (such as cinnamon, ginger, and cardamom essential oils), whereby consumers can be gradually accustomed to new flavors. The present study introduces the Dracocephalum kotschyi as a rich source of antioxidants. In the present study, valuable data are presented to compare the application of natural antioxidants of D. kotschyi vs. a synthetic antioxidant like tert-butylhydroquinone (TBHQ) in a popular product. In addition, D. kotschyi is introduced as a natural antioxidant potential to the oil industry and oil-dependent food industries, which can not only reduce the nutritional risks of synthetic antioxidants, but also increase the marketability of oil-rich food products. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3Synthetic Route of C12H20O2).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
