Optimized extraction and quality evaluation of Niger seed oil

Niger seeds with the scientific name of Guizotia abyssinica Cass and English name of Niger from Asteraceae family contain high‐quality oils with potential applications in nutraceutical and pharmaceutical fields.

Higher oil yields were obtained after continuous microwave cooking of flaked seeds with an increase in expeller oil recovery of 4.2% (mass of seed basis) and 9.2% (oil in seed basis) compared with an increase of 4.3% (mass of seed basis) after either MW. CRediT authorship contribution statement

Their Environmental and Economic Impacts

Several parameters need to be considered to improve oil extraction yield and quality, and one such example is screw rotation. When using a pilot expeller press designed for cold pressing, increasing rotation from 1.2 to 18 rpm increased press capacity from 2.2 kg seed/h to 29.4 seed/h, while decreasing canola oil yields from 91 to 84% [20].

Expeller pressing is the main process for the extraction of oil from canola seeds.

Mechanical Continuous Oil Expression from Oilseeds

The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw ...

When using a pilot expeller press designed for cold pressing, increasing rotation from 1.2 to 18 rpm increased press capacity from 2.2 kg seed/h to 29.4 seed/h, while decreasing canola oil yields from 91 to 84% . Additionally, the number of presses was shown to affect the oil yield and the quality of linseed oil.

Innovative technologies to enhance oil recovery

The use of a continuous microwave process for combined conditioning of whole seeds at 55 °C and subsequent cooking of flaked seeds at 100 °C resulted in a 4.0% increase in expeller oil yield ...

The aim of this study was to investigate factors influencing seed yield, postharvest handling, and the oil expression efficiency for nigerseed (Guizotia abbysinica Cass.). Based on field study on two varieties, two locations, three seed rates and three fertilizer rates the highest mean nigerseed yield was 1384.6 kg ha-1 at Adet location (rain fed)

Guizotia abyssinica

Niger seed yields about 30–35% of its weight in oil which is clear, slow-drying, and edible. Niger seed oil is a polyunsaturated semi-drying oil. It has a pale yellow or orange color with a nutty taste and sweet odor. The raw oil has a low acidity and can be used directly for cooking.

whole seeds at 55 C and subsequent cooking of flaked seeds at 100 C resulted in a 4.0% increase in expeller oil yield, compared with steam conditioning and cooking. The influence of dry basis (db %) moisture contents of 5%, 11.5%, and 16.5% on oil yield after steam or MW treat-ments of seeds and flaked seeds was also studied. The
