“…In terms of industrial application, MAE is considered as feasible method, due to its lower costs, in comparison to supercritical carbon dioxide extraction. In fact, large‐scale extraction reactions (hyphenated with microwave coaxial antenna) can extract 10–100 kg of fresh plant material/batch (Kokolakis & Golfinopoulos, 2013). Nevertheless, the requirement of special equipment, occurrence of uncontrolled biochemical reactions at elevated temperature, and poor selectivity are considered as some drawbacks of MAE (Delazar et al ., 2012).…”

Summary Berberis species are known for their functional and nutraceutical properties. For example, different Berberis species have shown a wide range of pharmacological activities and they have been used in food industries as additives, preservatives and antioxidants. The functional property of any herb is influenced by many factors including the extraction process of its active components. Consequently, new extraction methodologies have been investigated to increase the efficiency of extracting bioactive compounds. In this review, we examine all the recent extraction techniques and advanced technologies that have been applied for the extraction of phytochemicals from different Berberis species. The five following techniques have been included for this purpose: ultrasound‐, microwave‐, pulsed electric field‐assisted, supercritical carbon dioxide and subcritical water extraction. These techniques have been used to extract phenolics, flavonoids, anthocyanins and berberine from different parts of various Berberis species which include B. vulgaris, B. jaeschkeana, B. aristata, B. integerrima, B. dasystachya and B. koreana. Microwave‐assisted extraction (MAE) has been well studied, optimised and evaluated. Yet, the present research considering other techniques are limited, and require further investigation and optimisation. In addition, the application of green solvents such as natural deep eutectic solvents could be considered in further developing MAE.

“…Regarding therapeutic products, microwaves are useful for freeze-thaw treatment of injectable drugs [20] or hold potential for vaccine production [21]. Microwave assisted extraction is a possibility for fragrance production [22], and became a popular method for extracting natural products and active ingredients from plants [23,24]. Another potential application of microwaves could be the preparation of safe drinking water [25].…”

Microwave Technologies: An Emerging Tool for Inactivation of Biohazardous Material in Developing Countries

Inappropriate treatment and disposal of waste containing biohazardous materials occurs especially in developing countries and can lead to adverse effects on public and occupational health and safety, as well as on the environment. For the treatment of biohazardous waste, microwave irradiation is an emerging tool. It is a misbelief that microwave devices cannot be used for inactivation of solid biohazardous waste; however, the inactivation process, and especially the moisture content, has to be strictly controlled, particularly if water is required to be added to the process. Appropriate control allows also inactivation of waste containing inhomogeneous compositions of material with low fluid/moisture content. Where appropriate, especially where control of transport of waste cannot be guaranteed, the waste should be inactivated directly at the place of generation, preferably with a closed waste collection system. In waste containing sufficient moisture, there are direct useful applications, for example the treatment of sewage sludge or human feces. A number of examples of microwave applications with impacts for developing countries are presented in this review. In respect to energy costs and environmental aspects, microwave devices have clear advantages in comparison to autoclaves.

“…But there are a few sophisticated microwave technologies with appropriate measurements not only described in the literature but also commercially available. While these technologies are currently only used for the treatment of biohazardous waste, it still needs to be evaluated whether they would also have advantages for processes involving the control of water content such as the drying of biotherapeutic products (Walters et al, 2014) or the isolation of oils from herbs, flowers, and spices (Kokolakis and Golfinopoulos, 2013.…”

“…For fragrance production, microwave-assisted techniques have been introduced as a viable alternative for the isolation of essential oils from herbs, flowers, and spices. They have shorter extraction times and provide a higher quality essential oil with better sensory and antioxidant properties (Kokolakis and Golfinopoulos, 2013). Microwave-assisted extraction also became one of the most popular and cost-effective extraction methods for natural products and of active ingredients from plants (Chan et al, 2011;Delazar et al, 2012).…”

Microwave as an emerging technology for the treatment of biohazardous waste: A mini-review

Microwave is an emerging technology to treat biohazardous waste, including material from healthcare facilities. A screen of the peerreviewed literature shows that only limited information may be found in this area of work and, furthermore, analysis of the references reveals that sometimes not all necessary aspects for the appropriate use of the technology are considered. Very often conventional microwave technology is applied for the inactivation of pathogens, which might make sense for certain applications but, on the other hand, may lead to the misbelief that microwave systems cannot be used for the inactivation of a solid "dry" waste. However, conventional microwave units have no means to control the inactivation process, and especially moisture content. But there are a few sophisticated microwave technologies with appropriate measurements allowing a validated inactivation of biohazardous materials. These technologies are an effective tool for inactivation and some of them are commercially available. It must also be considered that the waste should be preferably inactivated either directly at the place where it is generated or biohazardous waste should be transported only in closed systems. Moreover, microwave technology presents a possibility to save energy costs in comparison to the more widely used autoclaves. This mini-review will discuss important aspects for the use of microwave technology for the treatment of biohazardous waste.
