Our Mustard Seeds (Rai) are whole, dried seeds of Brassica juncea and Brassica nigra, the brown and black mustard varieties prized across Indian, Asian, and European cuisines for their high oil content and intense pungency. Sourced from Rajasthan, Gujarat, and neighbouring belts, the seeds are 1–2 mm in size, dark brown to almost black, and machine-cleaned/sortexed to export-grade purity for reliable performance in manufacturing. kapadiyaexpocompany +4 When briefly fried in hot oil or ground and hydrated, these seeds release sharp, spicy heat and a nutty, aromatic depth that forms the backbone of pickles, tadka for dals and curries, chutneys, whole-grain and Dijon mustards, marinades, and ready-to-cook spice mixes. Their naturally high oil content (around 30–40%) and protein levels make them valuable not only for condiments but also for mustard oil, table mustards, and value-added products serving both domestic and international markets. wikipedia +4
