A method of determining a constituent related sample property of a multi-constituent sample comprising: subjecting the sample to a perturbation selected to induce a time dependent change in measurement data associated with a constituent related to the sample property to be determined; recording a time-series of measurement data following subjecting the sample to the perturbation; and determining the sample property from the application to the recorded time-series of measurement data of a calibration correlating the sample property with time-series of measurement data, said calibration being empirically derived from chemometric time-series modelling of time-series measurement data recorded for each of a plurality of reference samples following subjecting each reference sample to the perturbation, each reference sample having a different known values of the sample property.

A portable electronic alcohol-testing device is provided that uses vaporization and sensitive pressure guages to approximate the alcohol content of a solution. The device may be used, for example, to determine the relative alcohol content of a mixed beverage.

In one embodiment, authentication of a beverage is performed by forming an airtight seal with a bottle that contains the beverage, the bottle being sealed with a closure, applying a vacuum to the bottle to draw a sample from the closure that includes traces of the beverage, collecting the sample over time as the vacuum is applied to the closure, and performing testing on the collected sample.

The invention consists of a method for determining Total Dietary Fiber (TDF) and its sub-fractions, Insoluble Dietary Fiber (IDF) and Soluble Dietary Fiber (SDF) in food and feed samples which utilizes flexible reaction/filtration containers that can be divided into one or more sections for capturing the IDF and SDF fractions separately or for capturing TDF in its entirety. Each container is fashioned as a bag that can be temporarily sealed in multiple locations to create multiple sections and is made of non-porous and porous material. Use of these containers eliminates the need for problematic transfers of mixtures from beaker to filter, and vastly improves the filtration process.

Described are systems and methods for the simple and rapid measurement of an analyte, such as sulphur dioxide, in liquid samples, including beverages such as wine or beer. The systems and methods utilize voltammetry with a particulate carbon or copper electrode, and may be conducted outside of a laboratory in ten to sixty seconds using a small portable instrument or mobile device using, for example, 2nd harmonic Fourier Transform (FT) AC voltammetry.

A bottle with sensors for probing and optimizing bottling line performance is disclosed. According to one embodiment a bottle, comprises an outer layer and a reservoir tube inside the outer layer that connects a reservoir inside the outer layer to a neck of the bottle. The bottle has a battery inside the outer layer and one or more sensors powered by the battery.

A first series of images of a first fluid is received. A first set of fluid characteristics of the first fluid is determined from the first series of images. A second series of images of a second fluid is received. A second set of fluid characteristics of the second fluid is determined from the second series of images. A match is determined to be found between the first set of fluid characteristics and the second set of fluid characteristics. The second fluid is identified based upon determining that the first set of fluid characteristics matches the second set of fluid characteristics.

A product quality analysis and control system is provided. The product quality analysis and control system includes a processing system that is configured to receive data of objective qualities of a product from multiple data gathering modules. Each of the multiple data gathering modules is respectively positioned at corresponding nodes of a supply chain and is configured to receive from sensors data of objective qualities of a product when the product is at each of the corresponding nodes. The processing system includes a model repository and a data evaluation module. The data evaluation module is configured to select, from the model repository, a model associated with a type of the product and to use the model to analyze the data to identify changes in the objective qualities along the supply chain.

The present invention relates to a method for identifying and/or authenticating a sample, comprising adding at least one chemical compound to the sample, determining a level of the at least one compound after addition to the sample; comparing the level of the at least one compound to a reference level and identifying the sample based on the comparison with the reference sample and the effect of the sample on the level of the at least one compound. The invention further relates to the use of the at least one compound in the method for identifying and/or authenticating a sample. Further, the invention relates to the use of a kit comprising the at least one compound in the inventive method. In addition, the invention relates to a composition comprising the at least one compound. Further, the invention relates to a kit comprising the compositions provided herein, e.g. for calibrating the methods provided herein and/or the instruments employed in the methods provided herein.
