Abstract

This study examines the impact of microwave processing on Kachnar (Bauhinia variegata) powder and its application in flatbreads. Microwave treatment reduced anti-nutrient levels of alkaloids, phytates, tannins, and saponins by 83–90 %, enhancing safety. Incorporation of microwaved kachnar powder (MwKP) into flatbreads at 2.5–10 % replacement levels improved nutritional profiles, with increases in ash (0.4–0.9 g/100 g), dietary fiber (2–3 g/100 g), protein (8–9 g/100 g), and minerals such as Fe (3–4 mg/100 g), Zn (3.2–3.9 mg/100 g), Na (3–10 mg/100 g), K (378–388 mg/100 g), Ca (30–45 mg/100 g), and Mg (125–145 mg/100 g). Antioxidant activity also increased significantly (p < 0.05) as measured by DPPH, ABTS, FRAP, and total phenolic and flavonoid contents. Sensory evaluation showed a decline in acceptability for MwKP levels ≥7.5 %, though 5 % supplementation was well-received. The findings suggest that microwave processing is an effective method for reducing anti-nutrient content in Kachnar while improving its nutritional and antioxidant properties, making it a viable ingredient for enhancing baked goods.

微波加工对卡赫纳尔粉和辅料扁面包的营养、抗营养、抗氧化和感官特性的影响

本研究探讨了微波处理对 Kachnar（变种洋紫荆）粉的影响及其在扁面包中的应用。微波处理使生物碱、植酸盐、单宁酸和皂苷等抗营养素含量降低了 83-90%，提高了安全性。在扁面包中加入 2.5%-10% 的微波卡赫纳粉（MwKP）可改善营养成分，增加灰分（0.4-0.9 克/100 克）、膳食纤维（0.5-0.6 克/100 克）和淀粉（0.5-0.6 克/100 克）。9 克/100 克）、膳食纤维（2-3 克/100 克）、蛋白质（8-9 克/100 克）和矿物质，如铁（3-4 毫克/100 克）、锌（3.2-3.9 毫克/100 克）、纳（3-10 毫克/100 克）、钾（378-388 毫克/100 克）、钙（30-45 毫克/100 克）和镁（125-145 毫克/100 克）。根据 DPPH、ABTS、FRAP 以及总酚和类黄酮含量的测定，抗氧化活性也明显提高（p < 0.05）。感官评估显示，当 MwKP 含量≥7.5%时，可接受性下降，但 5%的补充量则很受欢迎。研究结果表明，微波处理是一种有效的方法，可以降低卡其纳尔中的抗营养素含量，同时提高其营养和抗氧化特性，使其成为改善烘焙食品的一种可行配料。
