High-performance liquid chromatography and gas chromatography to set the analysis method of stearoyl lactylate, a food emulsifier.

Stearoyl lactylates (SLs, E481/E482) and their sodium and calcium salts are emulsifiers commonly used as food additives. This study was performed to set the analytical method of SLs in Korea using high-performance liquid chromatography (HPLC) and gas chromatography (GC). A new HPLC method using C18 column with water and methanol as the eluents, and a new GC method using DB-1 column with He as the carrier gas, were developed and were compared with previously reported analytical methods.

A Decrease of Incidence Cases of Fumonisins in South Korean Feedstuff between 2011 and 2016.

Several plant pathogen species produce fumonisins (FUMs); which can end up in food and feed and; when ingested; can exhibit harmful effects on humans and livestock. Mycotoxin intoxication by fumonisin B₁ (FB₁) and fumonisin B₂ (FB₂) can cause porcine pulmonary edema; leukoencephalomalacia in equines; esophageal cancer and birth defects by natural contamination. Herein; the occurrence of FB₁ and FB₂ in feedstuff (compound feed and feed ingredients) was investigated between 2011 and 2016 in South Korea.
