A high resolution LC-ESI-QTOF-MS, LC-MS/MS, and HPLC-DAD analysis were conducted to isolate, identify and quantify the chlorogenic acids in 17 sweet potato varieties cultivated in Korea. The impacts of extracting solvent mixture system on the quantity and composition chlorogenic acids of the extracts were studied. It was found that extracting solvent mixture system greatly affected the quantit ...

A study was conducted to determine the rheological properties of green and gold kiwifruit purees with total soluble solids of 16 to 17 °Brix at different temperatures (25, 35 and 45 °C). The rheological properties of the samples were determined using a rotational rheometer at a shear range of 32 to 4835 s-1. The green and gold kiwifruit purees were found to be Non-Newtonian fluids following th ...

Chemical composition of seeds of two minor oil crops, flax (Linum usitatissimum L.) and oil hemp (Cannabis sativa L.) cultivated in Finland were analyzed and compared to others. Oilseed flax cultivars were Abacus, Aries, Comtess, Heljä, Helmi, Laser, Sunrise, and Taurus, three fiber flax cultivars were Belinka, Martta and Snaigiai. Oil hemp cultivar was Finola, a Finnish cultivar with low cann ...

Rapid advancement of nanotechnology has caused serious concerns over the potential release and accumulation of engineered nanoparticles (ENPs) in the environment. Gold nanoparticles (AuNPs) in particular, has attracted significant attention due to their broad applications. However, most previous toxicity studies have been heavily focused on animal and human cell lines, with limited information ...

The aim of this study was to assess the anti-obesity effect of Lactobacillus acidophilus-fermented mixture of skim milk, red ginseng extract, and immature fruit of Rubus coreanus Miquel (called black raspberry) extract in a mouse model of diet-induced obesity. Male C57BL/6J mice were fed a normal diet (ND), high-fat diet (HFD), high-fat diet supplemented with fermented skim milk (HFD-FSM), or ...

The two biotechnologically important Ascomycetes, Pichia membranifaciens and Debaryomyces hansenii, were tested (in active and inactive form), in the present study for efficient bioreduction of trivalent aurum to gold nanoparticles. Strong surface plasmon resonance was observed, between 530 and 540 nm, from the gold nanoparticles recovered from the test Ascomycetes. The characterization of the ...

Mutation is the process leading to heritable changes in the genetic material of an organism and caused mainly by the external factors, including chemical and physical agents, or can also occur spontaneously due to errors in DNA replication, repair, and recombination. Agents contributing to the mutagenic burden in the environment could be from industrial sources, wide spectrum applications of b ...

The antimicrobial activity of nanoparticles of silver in an active packaging and the effect of its combination with moisture absorbers over various parameters of the quality of tuna snacks was investigated. As a results, aerobic mesophilic bacteria growth were delayed during the first eight days of study; enterobacteria do not grow in snack tuna samples packaged with nanoparticles of silver an ...
