Extending the Lifetime of Frying Oil through Optimization of Fryer Cleaning.

With increases in consumer demand for fried foods in Japan over the last several decades, the consumption of frying oil has also steadily increased. Fryers used in restaurants to cook large quantities of food are typically cleaned using neutral kitchen detergents at the end of the day after removing the oil from the tank. However, significant amounts of debris can remain in the fryer after cleaning, possibly accelerating oil deterioration and thus reducing the quality of the fried foods.

Efficacy of Bright Greenish-Yellow Fluorescence Sorting on Mycotoxin-Contaminated Nutmeg Selection and Characterization of Fungal Flora Related to Mycotoxin Production.

Spices have been known to be highly contaminated commodities with mycotoxins. The Codex Alimentarius reports that nutmeg is particularly contaminated with aflatoxins (AFs) and ochratoxin A (OTA). To eliminate contaminated commodities, visual sorting and bright greenish-yellow fluorescence (BGYF) sorting are used as low-cost technologies in production engineering.

Electrophysiological Effect of Citreoviridin on Human InducedPluripotent Stem Cell-derived Cardiomyocytes.

Citreoviridin (CTV) is a mycotoxin produced by various fungi, including Penicillium citreonigrum. One of the toxicities reportedly associated with CTV is neurotoxicity. CTV is also suspected to be associated with acute cardiac beriberi (also known as "Shoshin-kakke") and Keshan disease, which can have adverse effects on the heart, so the in vivo and in vitro toxicity of CTV on the heart or cardiomyocytes in experimental animal models have been reported.

The Patrol Yeast: A new biosensor armed with antibody-receptor chimera detecting a range of toxic substances associated with food poisoning.

Baker's yeast is an attractive host with established safety and stability characteristics. Many yeast-based biosensors have been developed, but transmembrane signal transduction has not been used to detect membrane-impermeable substances using antigen-antibody interactions. Therefore, we created Patrol Yeast, a novel yeast-based immunosensor of various targets, particularly toxic substances in food.

[Analysis of Ciguatoxins in Variola louti Captured off the Ogasawara (Bonin) Islands].

Ciguatera poisoning (CP) is one of the most abundant seafood poisonings in the world. CP frequently occurred in the tropical and subtropical Indo-Pacific Ocean and the Caribbean Sea. In Japan, CP cases have been reported annually, from the subtropical regions, including Okinawa Prefecture and Amami Islands, Kagoshima Prefecture.
