Craft beer has an ever-increasing importance in the current market and the type of product offered can determine the market response. Microwave extractors for the food sector can bring great innovation to the beer production sector. We interviewed Dr. Nicola Grande, a master brewer, about this.

Discover the 2 new microwave protocols developed by Milestone, that have as ultimate target FAME analysis enabling, during the preparation process, a sequential determination of total fat (Method A) and free fat (Method B).

Food products are routinely analyzed to determine their composition in saturated and unsaturated fatty acids to communicate their nutritional value, monitor their quality and origin, and confirm the absence of TFAs In cooperation with Gembloux Agro-Bio-Tech, University of Liège, Belgium, a new and accurate method was developed for preparing FAMEs from a wide variety of foodstuff using a single-step microwave-assisted extraction and derivatization coupled with GC×GC analysis to identify and quantify the individual fatty acid. Results was also compared with those from two different official FAMEs preparations: AOCS Official Method Ce 2b-11 and Cruz-Hernandez et al. J AOAC Int 87(2) 2004 545.

In this case study, you can read how ACEA (acronym for Municipal Energy and Environment Company) gained advantages in terms of time-saving, application capabilities, maintenance costs and productivity on any kind of matrix, when adopting Milestone’s microwave technology instead of conventional extraction techniques

Dioxins are toxic and persistent molecules covered by the Stockholm Convention and several governments require their analysis in environmental samples. Microwave assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Milestone’s ETHOS X equipped with SR-15 eT rotor and glass vial kit was used in this study to prove its efficacy in the extraction of dioxins from fly ash samples. Discover the study that represents a guideline for the extraction of dioxins and furans from standard reference materials using the official method EPA 3546.

ISO 16703:2004 specifies a method for the quantitative determination of the mineral oil (hydrocarbons) content in field-moist soil samples by gas chromatography. Many environmental laboratories use this method daily. Microwave-assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Milestone’s ETHOS X with fastEX-24 eT rotor was used in this study to prove its efficacy in the extraction of hydrocarbon from soil samples in comparison with the ISO method.

Commission Regulation (EU) 2021/1199 of 20 July 2021 introduce new restrictions as regards polycyclic-aromatic hydrocarbons (PAHs) in granules or mulches used as infill material in synthetic turf pitches or in loose form on playgrounds or in sport application

Milestone's ETHOS X microwave enhanced extraction system can reduced the extraction time to 15 minutes. It also delivers a product with higher purity compared to traditional extraction methods that are based on the use of organic solvents

Total fat determination in food and feed matrices is a routine analysis for several testing and food processor labs, as it is part of labelling process and QC testing. Nowadays, the process still relies on outdated and matrix-dependent methods which use obsolete and time-consuming technologies. In the ETHOS X hydrolysis and extraction are done in a single step and in less time, ensuring higher productivity and better workflow. The ETHOS X method for total fat determination is applicable to any matrix; enables to process 45 sample a day, ensure lower cost per sample, offers complete fat determination and it is safe and compact.
