Pomelo (Citrus grandis .Linn Osbeck) oils is becoming more and more popular for everyone because it has great benefits. However, the efficiency of essential oil extraction process depends on the method and is influenced by a number of factors. Microwave-assisted hydro-distillation and Response Surface Methodology are selected for extracting and optimizing the factors affect the yield of the pomelo oil. The pomelo oil has the optimum yield was 4.5% when extracted with a water and peels ratio of 3,119: 1 (ml/g) for time extraction of 117.336 (minutes) at a microwave power of 403.115 (W) with high reliability (R2 = 0.9831)

Garlic Essential Oil

Factors affecting microwave-assisted extraction of garlic essential oil from garlic were investigated experimentally. Suitable conditions for such extraction process were studied by single factor approach to improve the product yield. The product yield under the resultant suitable conditions can reach to 0.478% based on raw garlic cloves. The product yield for microwave-assisted extraction method is as 2.5 times as that for conventional solvent extraction approach.

Essential oil extraction of wild caraway and thyme was performed using a classical (HD) and microwave hydro-distillation (MWHD) and a laboratory supercritical fluid extraction (SFE) with a carbon dioxide as solvent. Our experiments demonstrated that the extraction yield of the essential oil performed in same conditions was influenced by the location of growth area; the maximum extraction yield of 10 ml 100 g-1 caraway was obtained from dried seeds collected from Csíkmadaras. This quantity far exceeded the yield of the Újtusnád samples. In the case of wild caraway (Carum carvi L.), the extraction method influenced thecomposition of the essential oil (carvone/limonene ratio), the highest limonene content being achieved by classical hydro-distillation. In the case of thyme, this effect was not detected, the thymol/carvacrol ratio was independent from the given extraction method. The obtained thyme essential oil possesses high antimicrobial activity demonstrated by agar diffusion test. The thyme extract provides a good protection against microorganisms collected on the surface of fresh vegetables following bacterial stains: Citrobacter portucalensis, Pseudomonas hunanensis, Pseudomonas baetica, Pseudomonas parafulva, Bacillus mojavensis and Enterobacter cloacae. Protective effect was also detected on the vegetable surface of by chitosan-based edible film coating during a 6-day-long storage period at a temperature of 4 °C. The caraway essential oil used as soft cheese seasoning with a direct, dilution-free method, proved to be unsuitable because the uneven distribution and confer a strong, unpleasant taste to the product in comparison with the ground wild caraway seed-dressed cheese.

Acantholippia deserticola (Rica-Rica) is a native shrub of the Chilean highlands used as a medicinal plant and food dressing. The objective of this study was to compare the physical, antioxidant and antimicrobial characteristics of its essential oil (EO), based on the process parameters and extraction methods using hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD), and assessing presence of fatty acids. The process performance as well as the colour parameters, refractive index, fatty acid profile, antioxidant activity and antimicrobial activity were evaluated. The best process conditions for HD were 90 min, 420 W and 150 g 1000 mL–1; for MAHD, these were 90 min, 700 W and 200 g 1000 mL–1, with yields of 0.45 and 0.49 mL 100 g-1 and antioxidant capacities of 2.38 and 3.92 µmol Trolox g-1 respectively. The collection season, extraction method and its parameters affected the yield and fatty acid profile, influencing EOs’ activity. In terms of mass of herbs, process time as well as energy efficiency and environmental impact, the extraction of MAHD was 8% more efficient. EOs extracted by both methods show a slight inhibitory effect on Streptococcus sp. and Bacillus cereus, and MAHD EO showed a highly inhibitory effect on Streptococcus Group A. The type of extraction method and the process parameters could be set to obtain suitable EOs according to its potential industrial application.
