A rapid, low-cost, portable and reliable method for on-site detection of deoxynivalenol (DON), a representative mycotoxin predominantly occurring in grains, would be helpful to control mycotoxin contamination. Herein, a paper-based microfluidic chip capable of measuring deoxynivalenol (DON-Chip) in foods, feeds and feed ingredients was developed. As discussed herein, the DON-Chip incorporated a colorimetric competitive immunoassay into a paper microfluidic device and used gold nanoparticles as a signal indicator. Furthermore, a novel ratiometric analysis method was used to improve signal resolvability at low concentrations of DON. Detection of DON in aqueous extracts from solid foods, feeds or feed ingredients was successfully validated with a detection range from 0.01-20 ppm (using dilution factors from 10-10.sup.4). Compared with conventional methods, the novel DON-Chip greatly reduces the cost and time of mycotoxin detection in the food and feed industry.

A jaw movement analysis system includes circuitry that is configured to acquire chewing information including time-series information that represents a jaw movement of a user chewing a bite of food, and to determine an attribute of the food having been chewed by the user based on the chewing information acquired and based on an analysis model. The analysis model is generated by machine learning based on training data including first information that includes time-series information indicating a past jaw movement during a chewing of a bite of food, and second information that indicates an attribute of the food chewed during the past jaw movement associated with the first information.

The invention relates to a method for extracting mycotoxins from grain and other food products or from feed and its subsequent quantification. Fields of application are the food industry, the animal feed industry or biotechnology. The objective of the present invention is to develop an extraction method with which it is possible to uniformly extract mycotoxins with different dissolving properties. It was found that with the aid of aqueous, buffered naphthyl and/or phenyl compounds or their heterocyclical analogues, both hydrophobic and hydrophilic mycotoxins can be extracted. The method according to the invention is characterized in that the buffered solutions of naphthyl and/or phenyl compounds and/or their heterocyclical analogues, which carry at least one sulphonic acid or at least one carbonate acid group, are brought into contact with the grain or other food products or animal feed, the aqueous solution is then separated and the content of the extracted mycotoxins in the aqueous solution is determined.

Methods and apparatus, including computer program products, for food product testing in a production system. An automatic determination is made in response to entering a product sampling value for a food product into an electronic test record, wherein the food product is associated with a batch identifier, as to whether the product sampling value fits within a specified range of product sampling values. The food product is classified based on the determination into a completed, pending, or quarantine class. Information about the classification of the food product is provided to a user and the user is prompted to take an action with respect to the food product. The provided information and the prompted action are customized based on a role of the user.

The present disclosure relates to biosensors (10) having a receptor layer (5) and a mediator layer (6), the receptor layer including ethylene receptor molecules. The present disclosure also relates to sensor units (20) comprising one or more biosensors (10) and a controller (11). In some embodiments, one or more sensor units (20) may be in wireless communication with a receiver module or a network gateway.

Material waste screening is provided. A sensor obtains data related to an object. A processor classifies the object based on the data to identify a recycle category for the object, open a recycle bin for the identified recycle category, instruct the operator to deposit the object in the opened recycle bin, determine a level of compliance of the object, and create at least one new instruction to increase the level of compliance.
