Abstract

Acid value (AV), polar compound content (PC), carbonyl value (CV) and Gardner color of oil used for deep-frying in kitchens at a supermarket, lunch chain store, restaurant, eating house, and hospital were analyzed. All AVs obtained but one (3.38) were within the limit set by the Food Sanitation Act of Japan (AV ≤ 3, peroxide value ≤ 30). However, some oil samples had a PC over 25%, which is beyond the limit legislated by some European countries. When the relation between the Gardner color and the AV, PC, or CV of the oil was investigated, well correlated logarithmic regression curves were obtained from the oil of all kitchens except the hospital kitchen. However, the use of lard-containing canola oil without oil replenishment in the eating house increased color values rapidly. All of the values obtained from pure vegetable oil used almost daily were plotted on a graph. It was found that kitchen-by-kitchen differences in fryer, vegetable oil, frying temperature, heating time, and amounts and kinds of foods fried did not influence the relation between Gardner color value versus AV, PC or CV. In conclusion, frying vegetable oil used in large-scale kitchens without official inspection can be better controlled with Gardner color det...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
