Proposed is a quality analysis nanosensor using a metastructure, including: a metasurface structure resonating with a specific frequency of incident electromagnetic waves; a fixed binding body formed on a surface of the metasurface structure or inside the metasurface structure on a hotspot area; a movable binding body coupled to the fixed binding body by an attractive force; and a receptor or nanoparticles linked to the movable binding body. According to the nanosensor, there are provided a detection structure and method based on metamaterials and nanoparticles, thereby enabling efficient detection with only few nanoparticles by raising detection sensitivity to a high level.

The invention relates to a device for crumbling root crops into substantially equal sized pieces and homogenizing the flow of crumbled pieces for analysis. The device can have a crumbling device with a main frame and at least one crumbling shaft rotatably supported in the main frame. The crumbling shaft can have a plurality of curved hooks for interlaced movement with recesses in at least one non-rotating cutting rake and at least one cleaning rake. A transport device can move the stream of crumbled root crops from the crumbling device where the stream can be leveled with a leveling rake and compressed into a substantially flat and uniform flow with a roller. The roller can have one or more scrapers positioned to clean the roller surface of residual root crop product and distribute the cleaned material in locations away from the stream to be analyzed to avoid contamination.

Example virtual tasting systems and methods are described. In one implementation, a virtual tasting system identifies multiple food products, multiple tasters, and multiple questions. The virtual tasting system then identifies a full set of quadruplets of the form: first food product, second food product, taster, question. A subset of quadruplets from the full set of quadruplets are then identified. The virtual tasting system then measures a value associated with each quadruplet from the subset of quadruplets. The virtual tasting system then outputs estimated values associated with every triplet in a full set of triplets of the form: food product, taster, question.

A system enables a consumer to place an order for a food item by entering characteristics and not necessary by its commercial name. The system prompts the consumer to enter the information about the desired food item and selects food items from a food database according to the characteristics entered. The selected food items are presented to the consumer for confirmation and the confirmed food item is sent to a selected restaurant for fulfillment.
