Buckwheat is a major traditional crop of hilly regions, capable of growing in adverse climatic conditions. During the survey, it was reported that prolonged consumption of buckwheat leads to digestive problems and numbness. The present study was conducted to study the effect of γ-irradiations on buckwheat to make them suitable for daily consumption.
Buckwheat seeds were irradiated by 100, 200, 300, 400, 500, 600, 700, and 800 Gy doses of γ-radiations, to access the phytoconstituent variability using standard methods.
Significant ( < 0.05) increase in total phenol, total flavonoid, total antioxidant activity, rutin, β-carotene, iron, calcium up to 6.23, 16.48, 18.62, 19.06, 8.08, 47.66, 32.74% in common buckwheat and 9.58, 16.66, 39.16, 9.19, 9.00, 53.99, 36.75% in tartary buckwheat was found by increasing doses of γ-radiations up to 800 Gy. Significant decrease was found in phytate, tannin, and oxalate content up to 18.92, 17.95, 15.32% in common buckwheat and 24.73, 19.72, 24.07% in tartary buckwheat.
It can be concluded that 800 Gy dose of γ-radiation, maximally increased the nutritional value by significant ( < 0.05) increase in nutrients and their bioavailability. This makes buckwheat more amenable for daily consumption to fulfill RDA, by Himalayan population depending on traditional foods without any digestive problem. Furthermore, significant increase in rutin by γ-radiations will be useful to fulfill the demand of cosmetic and pharmaceutical industries. But minimization of reduction loss for some nutrients by γ-radiations is the thrust area for future research.
荞麦是山区的一种主要传统作物，能够在不利的气候条件下生长。在调查中，有报告称长期食用荞麦会导致消化问题和麻木。本研究旨在研究γ射线辐照对荞麦的影响，使其适合日常食用。
用100、200、300、400、500、600、700和800 Gy剂量的γ射线辐照荞麦种子，采用标准方法评估其植物成分变异性。
随着γ射线剂量增加至800 Gy，普通荞麦中总酚、总黄酮、总抗氧化活性、芦丁、β-胡萝卜素、铁、钙含量显著（P<0.05）增加，增幅分别达6.23%、16.48%、18.62%、19.06%、8.08%、47.66%、32.74%；苦荞中上述成分增幅分别为9.58%、16.66%、39.16%、9.19%、9.00%、53.99%、36.75%。普通荞麦中植酸、单宁和草酸盐含量显著降低，降幅分别达18.92%、17.95%、15.32%；苦荞中上述成分降幅分别为24.73%、19.72%、24.07%。
可以得出结论，800 Gy剂量的γ射线辐照通过显著（P<0.05）增加营养成分及其生物利用度，最大程度地提高了营养价值。这使得依赖传统食物的喜马拉雅地区人群食用荞麦时更易满足每日膳食推荐摄入量，且不会有任何消化问题。此外，γ射线辐照使芦丁显著增加，将有助于满足化妆品和制药行业的需求。但γ射线辐照导致某些营养成分减少损失的最小化是未来研究的重点领域。
