Choosing the Right Microwave Extraction System
Microwave-assisted extraction (MAE) accelerates the recovery of target compounds from solid samples through controlled microwave heating. Compared with conventional solvent extraction methods, it can significantly reduce extraction times and solvent consumption while improving sample preparation efficiency and reproducibility.
Milestone ETHOS X solutions cover laboratory analysis and solvent-free extraction of natural products, from compact labstations to higher-capacity processing systems.

- Extraction of Terpenes: Solvent-free recovery of volatile terpenes from botanical materials.
- Hop Extraction for Breweries: True Hopping technology for efficient hop aroma extraction and utilisation.
How Does Solvent-Free Microwave Extraction Work?
Solvent-free microwave extraction (SFME) uses microwave energy to heat the moisture naturally present in botanical materials, releasing essential oils and other volatile compounds without adding organic solvents or water. The compounds are recovered through a controlled condensation process.
For laboratory applications, Milestone also offers microwave hydrodiffusion and gravity (MHG) configurations to extract flavours and other natural compounds, including pigments and flavonoids. The ETHOS X line extends solvent-free extraction to larger-scale natural-product processing.

Efficiëntere extractie van oplosmiddelen
The process of sample preparation represents a critical yet often overlooked aspect of chromatographic analytical procedures. It is here that errors are most likely to occur. Surprisingly, many laboratories still rely on the antiquated Soxhlet method, a technique dating back to 1879.
In contrast, Microwave-Assisted Extraction (MAE) employs sealed vessels to elevate the extraction solvent temperature beyond its atmospheric boiling point. This strategic approach offers several advantages. Firstly, the heightened temperature significantly enhances the solubility of the target analyte, while concurrently reducing solvent viscosity. As a result, MAE achieves two pivotal goals: more efficient sample preparation and reduced extraction durations.
Furthermore, the microwave-assisted extraction method stands out for its selectivity, speed, and the superior precision and accuracy it imparts to analytical results when compared to alternative approaches.
Microwave-assisted solvent extraction finds application in a wide range of scenarios, including the removal of organic pollutants from environmental matrices, determination of fat content in food samples, elimination of contaminants from food products, and the extraction of additives from plastics.

Extracten van hoge kwaliteit met een groen extractieproces
Om de beperkingen van conventionele extractietechnieken aan te pakken, heeft Milestone de ETHOS X-lijn ontwikkeld voor de extractie van natuurlijke producten zoals terpenen uit cannabis en hop, en essentiële oliën uit een groot aantal plantaardige producten. De ETHOS X-reeks maakt gebruik van het unieke microgolf selectieve verwarmingsmechanisme. De interne verhitting van water in het monster distilleert de cellen en leidt tot het openbarsten van de klieren en oliehoudende reservoirs. Door dit proces komen de terpenen vrij, die vervolgens verdampt worden met het water van het botanische product.
Toepassing: Echt hoppen
Om de efficiëntie van de extractie van hopsmaken bij het conventionele dry-hopping proces te verbeteren, heeft Milestone een nieuwe hoppingtechniek toegepast, True Hopping genaamd, die gebruik maakt van de beproefde SFME-aanpak (solvent-free microwave extraction).
Dit proces slaagt erin tot 95% van de hopterpenen terug te winnen en stelt brouwers in staat zeer hoppige smaakprofielen te creëren terwijl ze tot 40% minder hoppellets gebruiken.
