快速气相电子鼻-气味分析仪 Heracles NEO

The company proposes a wide range of traditional gelatins coming from pork, bovine or fish skins intended for pharmaceutical, food or technical applications. The group applies a strict policy in terms of traceability and products quality, in particular to guarantee that their gelatins have no unpleasant odor. As part of a partnership with OSEO, a French state company aimed at encouraging industrial innovation, Weishardt equipped with a HERACLES electronic nose (Alpha MOS, France).

We analysed a pink wine aged for one year with different shutters to determine which ones best preserved the aroma of wine over time. The analysis was performed both by our sensory panel and by Alpha MOS lab using their HERACLES Electronic Nose. Screw caps proved to best preserve the aroma profile of wines over time. On the contrary, synthetic shutters entailed a significant change in wine aromas, molded ones being less efficient than extruded ones for aroma preservation. The wines are oxidized. With synthetic and technical cork shutters, it appeared that compounds providing fruity notes, such as ethyl octanoate (pineapple note) experienced a significant decrease which contributed to the overall loss of aroma.

In ISOEN 2017 (17th International Symposium on Olfaction and Electronic Noses) held in Canada, we made 2 presentations: “Sensory Characterization of Oils Extracted from Lacto-Fermented Olives Using an Electronic Nose” and “Assessing Production of Medicinal Liqueur Using an Electronic Nose.” For the first topic, we received the Alpha MOS industrial award. Furthermore, utilizing the fact that HERACLES II is a very fast and high sensitive GC, we made a success in identifying the scent marker peculiar to the olive fruit disease and detecting 1% of the disease contamination (paper submitted). It is also possible to detect volatile toxic substances by heating of vegetable oil (paper submitted).

Conventional methods for product authentication are time-consuming, that’s why NAQS has implemented a testing method based on HERACLES Electronic Nose, which allows a fast and accurate identification of Kimchi origin. The recognition model set up with this instrument can successfully predict the origin of the tested samples with 99% accuracy and thus reliably recognise counterfeited products.

Over the past 3 years, the organization has undergone a transition from limited awareness of sensory attributes to broad quality awareness. By investing in an electronic nose (e-nose) in 2014, the company made a huge leap which distinguishes them from their competitors on the market with regard to quality.

Some months ago, before purchasing the instrument, we visited the manufacturer, Alpha MOS, in their headquarters in France. We brought some samples of olive oil, which is a product that suffers a high risk of adulteration. We could see that HERACLES could not only distinguish genuine from adulterated oils but also recognize the region of origin such as Tuscany, Puglia or Liguria.

With our sensory panel we check the finished closures/liners, and with the HERACLES E-Nose we check the raw granulate before it gets processed, to check for constant quality. We use the E-Nose for checking incoming goods (liner material, sealing discs for Long Cap closures, etc.), and for development and qualification of new materials (liner materials, lacquers (lacquered sheets), etc.) With HERACLES E-Nose we definitely achieved a higher quality level and thus have the opportunity to distinguish ourselves from competitors."
