From 1998 to 2016 it was published in Japan (Shinshu University, Ina, editor Toshiko Matano; Kyoto University, Kyoto, editor Ohmi Ohnishi; Kobe Gakuin University, Kobe, editor Kiyokazu Ikeda).

Acrylamide, a toxic food contaminant, was first identified in 2002 following its detection in Swedish food products. Our findings demonstrate that extracts from both buckwheat species significantly reduced DNA strand breaks. Tartary buckwheat contains higher levels of rutin, quercetin, and polyphenols, and exhibits greater antioxidant activity compared to common buckwheat. Due to endogenous rutin-degrading glucosidase activity, part of the rutin was enzymatically converted into quercetin. Processing generally decreased antioxidant activity, with the exception of wheat bread, where a slight increase was observed, likely attributed to Maillard reaction products.<span class="Apple-converted-space">&nbsp;</span></p> <p>We confirmed that acrylamide induces genotoxic effects in HepG2 cells at all tested concentrations (0.3125, 0.625, 1.25, and 2.5 mM) after 24 hours of exposure, and that methanolic buckwheat extracts effectively reduced the formation of acrylamide-induced DNA damage. The extract from Tartary buckwheat demonstrated the highest antigenotoxic activity, surpassing even pure rutin or quercetin at higher concentrations. These results suggest that although thermal processing can generate potentially harmful compounds, such as acrylamide, food matrices may simultaneously contain bioactive components capable of counteracting or mitigating such adverse effects.</p> Maja Vogrinčič Bojana Žegura Copyright (c) 2025 2025-07-08 2025-07-08 42 2 41 47 10.3986/fag0048 https://ojs.sazu.si/fagopyrum/article/view/8076 <p>Selenium in the form of selenate (Se VI) was foliarly applied to buckwheat plants to evaluate its influence on the uptake and accumulation of other selected elements, including copper (Cu), zinc (Zn), sulfur (S), molybdenum (Mo), iron (Fe), manganese (Mn), and cadmium (Cd). Among these, Cu, Zn, Mo, Fe, and Mn are essential elements while cadmium, on the other hand, is a toxic pollutant absorbed by plants from contaminated soils. Foliar selenium (VI) application resulted in modest changes in the concentrations of Cd, Mo, Fe, Mn, and S in the leaves; Cu in the husks; and Mo and Mn in inflorescences. However, selenium had no significant effect on Zn accumulation. These results suggest that foliar application of selenium (VI) may both enhance and inhibit the uptake of specific elements, with effects varying by plant tissue.</p> Maja Vogrinčič Vekoslava Stibilj Copyright (c) 2025 2025-07-08 2025-07-08 42 2 49 52 10.3986/fag0049 https://ojs.sazu.si/fagopyrum/article/view/8077 <p>Buckwheat tourism in Korea in two places, Bongpyoung town, Pyoungchang county, Gangwon province and Wahul village, Jeju city, Jeju province, is introduced in terms of background, current activities, and expected effectiveness from green tourism point of view.</p> Cheol Ho Park Min Ook Park Copyright (c) 2025 2025-07-08 2025-07-08 42 2 53 58 10.3986/fag0050
