“…Niger seeds (NS) are consumed by humans as an edible crop as they are rich source of protein, essential fatty acids (FAs), tocopherols, phospholipids, steroids, β‐carotenoids, and dietary fiber (Odedra et al., 2023). The bioactive compounds found in niger seed oil (NSO) have demonstrated a spectrum of activities like antioxidant, anti‐inflammatory, antimicrobial, antifungal, anticancer, and anti‐inflammatory effects (Solomon & Nkambule, 2022). Notably, the NS contains 40% oil with high proportion of linoleic acid (75%–80%) that functions as a fundamental constituent in plasma membranes and a precursor to crucial metabolic regulators.…”

Infrared heating (IRH) at 140, 160, and 180°C for varying durations (5, 10, and 15 min) was employed for improving the niger (Guizotia abyssinica) seed oil (NSO) quality for diverse food applications. The study explored changes in phenolic profile, oxidative stability index (OSI), tocopherols, phytosterols, fatty acid profiles, and physicochemical attributes of NSO. Upon IRH at 180°C for 10 min, the oil yield, total phenolic, and flavonoid contents increased from 33.09% to 40.56%, 6.67 to 173.62 mg GAE/kg, and 24.76 to 120.64 mg QE/kg, respectively. The viscosity, chlorophylls, carotenoids, radical scavenging activity, OSI, caffeic, protocatechuic, vanillic, and syringic acids were highest upon IRH at 180°C for 15 min. The tocopherols and phytosterols initially augmented while decremented upon raising IRH conditions. The infrared spectra indicated no adverse impact of IRH on NSO quality. The appropriate IRH conditions can be considered for improving NSO quality and making it valuable for various edible products.

Carbohydrates, lipids (mostly fats and oils), proteins, vitamins, minerals, and water are the six main classes of nutrients found in foods. After carbohydrates, oils are important source of major calories required in the human diet. Oils act as a vehicle for some of the important vitamins and possess a range of nutrients and bio-active compounds. These edible oil-yielding plants can be categorized into non-woody (herbaceous) and woody (non-herbaceous) oil-bearing plants. This chapter mainly focuses on important herbaceous edible oilseed (crop)plants such as pea(ground)nut (Arachis hypogaea L.), Indian mustard (Brassica juncea L. Czern. and Coss.), rapeseed (Brassica campestris L.) (syn. B. rapa), soybean (Glycine max L.), flaxseed (Linum usitatissimum L.), sunflower (Helianthus annuus L.), sesame (Sesamum indicum L.), safflower (Carthamus tinctorius L.), and niger (Guizotia abyssinica L.). It aims to (a) overview the key insights into the origin, botany and benefits of the mentioned herbaceous edible oilseed (crop)plants; (b) highlight the major constraints for their growth and productivity (quantitative-qualitative); (c) enlighten important mitigation-approaches for minimizing the constraints-accrued impacts; (d) briefly overview the major aims and achievements of important breeding programmes focused on these oilseed-bearing (crops)plants; and also to (e) briefly present important aspects least explored on the subject.
