[Detection of fish protein in food products by lateral flow immunoassay].

The major fish allergen is parvalbumin, a sarcoplasmic protein. In this study, a novel lateral flow immunoassay for the detection of fish protein in food products was developed using a polyclonal antibody raised against Pacific mackerel Scomber japonicus parvalbumin. The proposed lateral flow immunoassay showed high reactivity to various fish parvalbumins, but the reactivity to bullfrog parvalbumin was very low.

Evaluation of a novel rapid detection system for yeasts and molds.

A novel system, the NISSUI rapid detection system, has been developed to rapidly detect yeasts and molds in food. This system consists of a liquid medium containing resazurin as a redox indicator, a unique original micro-well dish containing 676 micro-wells, and a fluorescence-monitoring instrument with an incubator. To evaluate this system, orange juice, milk, and physiological saline solutions artificially inoculated with yeasts or molds were used as samples.
