“…Militias et al have done comparative studies on the chemical composition of EOs from plant extracts of conifers and was revealed with major modification. MAE has given 50% better yield of EOs and rate of flow with less time of extraction as compared to HD . Similarly, by using sonication waves in UAE, the kinetics was described in different ways.…”

In recent years, essential oils have received a growing interest because of the positive health effects of their novel characteristics such as antibacterial, antifungal, and antioxidant activities. For the extraction of plant-derived essential oils, there is the need of advanced analytical techniques and innovative methodologies. An exhaustive study of hydrodistillation, supercritical fluid extraction, ultrasound- and microwave-assisted extraction, solid-phase microextraction, pressurized liquid extraction, pressurized hot water extraction, liquid-liquid extraction, liquid-phase microextraction, matrix solid-phase dispersion, and gas chromatography (one- and two-dimensional) hyphenated with mass spectrometry for the extraction through various plant species and analysis of essential oils has been provided in this review. Essential oils are composed of mainly terpenes and terpenoids with low-molecular-weight aromatic and aliphatic constituents that are particularly important for public health.

“…Although less well described in the literature, an alternative approach for utilizing microwave heating of plant based materials has been to treat the materials with microwave energy prior to conventional extraction processes (Miletic, et al 2009). Microwave preconditioning of sugar cane prior to juice diffusion studies led to significant decreases in colour and significant increases in juice yield, Brix %, purity and Pol % (Brodie, et al 2011).…”

There is great potential for using radio frequency and microwave technologies to solve problems associated with agricultural production. Studies have been undertaken to use radio frequency and microwave energy: to improve crop handling, storage and preservation; to provide pest and weed control for agricultural production; for food preservation and quarantine purposes; for land survey; for automatic data acquisition and communication; and for preconditioning of products for better quality and more energy efficient processing. This chapter is concerned with radio frequency and microwave applications in the agricultural industries for purposes other than human food processing. Many of these applications will be more fully explored in subsequent chapters. 3.1 Heating Applications 3.1.1 Crop Drying Many studies have investigated the application of radio frequency and microwave energy to speed up crop and wood drying (Manickavasagan, et al. 2006, Setiady, et al. 2009). Microwave drying provides an alternative to traditional drying methods. Polar molecules are affected by radio frequency and microwave radiation; therefore polar molecule, such as free water, in a given matrix can be directly heated (Beary 1988). Bound water molecules are more difficult to volatilize because the fixed bond inhibits rotation (Beary 1988). Microwave drying is a rapid drying technique that can be applied to specific foods, particularly high value products such as fruits and vegetables (Zhang, et al. 2006). Increasing concerns over product quality and production costs have motivated industry to adopt radio frequency and microwave drying technologies. The advantages of these systems include: shorter drying time, improved product quality, and flexibility in producing a wide variety of dried products (Zhang, et al. 2006); however current applications are limited to small categories of fruits and vegetables due to high start-up costs and relatively complicated technology as compared to conventional convection drying (Zhang, et al. 2006). 3.1.2 Quarantine Dried timber, nuts and fruits are commonly treated by chemical fumigation to control field and storage pests before being shipped to domestic and international markets.
