Abstract: Cassia tora L. is legume anniual plant of species in which the seeds grow to develop into pods. It is also known as sickle pod, tora, coffee pod, tovara, chakvad, thakara in Malayalam foetid cassia. Tarwad is a dicot legume in the family and subfamily Caesalpinioideae. It grows wild in most of the tropics and is considered as a weed. Its native range is probably South Asia. Its most common english name is sickle senna or sickle wild sensitive-plant. Tarwad with high nutritive value is available abundantly in India. It is an “Underutilized Vegetable”, plant resistant to pests, diseases and thrives well in minimally nutritive soils. It is an annual foetid herb, 30-90 cm high. Leaves are green in colour, pinnate, up to 6-8 cm long, leaflets are in 3 pairs, distinctly petioled, opposite, conical at one end, ovate, oblong and base oblique. Flowers are pale yellow in color usually in nearly sessile pairs in the axils of the leaves with five petals, upper one are very crowded. Pods are substrate or 4 angled, very slender, 6-12 inch long, incompletely septet, membranous with numerous brown oblong, rhombohedral seeds. The engineering properties of tarwad (cassia tora L.) seeds were observed. The average shape, length, width, thickness, GMD, kernel weight, bulk density, tapped density, true density, angle of repose and coefficient of friction of tarwad seed was found to be irregular and rectangular, 4.37 mm, 2.16 mm, 2.08 mm, 2.69 mm, 29.24 g, 0.87 g/ml, 0.89 g/ml, 1.3 g/ml, plywood (16.4± 0.16) degree and plywood (130.2± 1.98), respectively. The engineering properties of tarwad (cassia tora L.) seed powder were observed. The average colour, angle of repose, bulk density, tapped density, carr’s index, hausners ratio and average particle size of tarwad seed powder was found to be yellowish, 35.02 degree, 0.608 g/ml, 0.690 g/ml, 11.71 per cent, 1.12 and 0.33 mm. The chemical properties of tarwad seed powder were observed. The average moisture content, ash content, crude fat, crude protein, crude fibre, carbohydrate, non-protein nitrogen, true protein and free amino acids of tarwad seed powder was found to be 5.55 per cent, 3.57 per cent, 1.06 per cent, 15.72 per cent, 4.07 per cent, 69.46 per cent, 0.25 per cent, 12.37 per cent and 0.99 per, cent respectively. The minerals content of tarwad seed powder was observed. The average of Ca, Mg, Fe, Cu, and Zn of tarwad seed powder was found to be observed that the mineral content of tarwad seed powder was found to be 70.522 mg/l, 11.122 mg/l, 0.4596mg/l, 0.003 mg/l and 0.8483 gm/l respectively. The water holding capacity in tarwad seed powder was found to be non-significantly superior in S2 Size. The water holding capacity of tarwad seeds powder was observed highest in case of S2 Size 80.02 per cent. Products prepared from tarwad seed powder i.e Pakoda and sweet shira showed better results for 4% concentration of tarwad seed powder as campier to 8% and 12% concentration of tarwad seed powder.
