Cereals and legumes are prone to perishability and have very short shelf-life if not given proper treatment. During different handling and marketing operations, there is a huge postharvest loss of agricultural produce. The qualitative and quantitative losses incurred in cereals and legumes commodities between harvest and consumption are huge. Qualitative losses such as loss inedibility, nutritional quality, calorific value, and consumer acceptability of fresh produce are much more difficult to assess than are quantitative losses. The major cause of postharvest loss (PHL) is the availability of poor infrastructure for postharvest technology (PHT) and processing of commodities. These losses can only be minimized by proper handling, marketing, and processing of the agricultural commodities; as well as the use of modern preservation technologies such as irradiation, radio frequency heating, etc. The sufficient knowledge of pre-and post-harvest preservation technologies and the provision of adequate and sufficient storage facilities for cereals and legumes handling and distribution would help to mitigate the incidence of postharvest deterioration and therefore improve the availability of cereals and legumes in the market and subsequent reduction in malnutrition for increased food security. Postharvest preservation technology of cereals and legumes is very fundamental in reducing postharvest losses and increasing food security.

Oilseeds have been cultivated from antiquity with increasing demand in agricultural industries world trade. Many economies such as Malaysia depend largely on oilseed crops which are grown primarily for the edible oil production; and for additional meal fraction arising from the seed. The meal is rich in protein and used for animal feed. Recent developments in research have posited oilseeds as a viable source for the production of biodiesel. In the tropics, most of the oilseeds are underutilized; and interest in its mass production and utilization are lacking. Some other seed such as neem seeds, pawpaw seeds, Jatropha curcas L. seeds, etc. have not been put to use in tropical countries leading to subsistence production and their applications in other areas. The oilseed crops could be used either for human, animal or for industrial purposes. There is need to increase the volume of production of these oils in tropical countries through improved quality farming techniques that would encourage breeding in other to meet up with increasing demands. Notably, there are many conventional methods that have been used to increase oilseeds yields. However, the adoption of each technology improvement should be sustainable, while other unknown oilseeds should be discovered for increased utilization.
