“…To enhance the productivity of the agricultural and food sector, applications of the nanomaterials and nanotechnology has been adopted [23] , [147] , [26] , [148] . Several kinds of research have adapted nanomaterials in the area of soil bioremediation, biochar enhancement for soil enrichment, crop protection, fertilizer application, renewable energy system application in agriculture, bio-sensors, disease control, and coating of crop processing system against corrosion to achieve high processing efficiency and crop detoxification [14] , [15] , [16] , [17] , [18] , [19] , [152] . Synthesis mechanism for materials makes use of atomic, fungi, molecular, processing of particulates in vacuum or fluid medium with the fungi method the most widely used due to high cost of adopting other methods [2] , [20] , [21] .…”

In this treatise, we examined the activities of researchers of Nigeria descent in the frontier areas of nanoscience and nanotechnology, with a focus on green nanotechnology. The exploration of literature published by scholars were reviewed and compartmentalized on the basis of applications of the nanomaterials. It can be concluded that the level of activities in this area is expanding owing to the emergence of more published works since the beginning of 2010. However, in comparison with research outputs from other developing African countries such as South Africa and Egypt, activities in green nanotechnology are still at low ebb in Nigeria. Issues that are contributory to the slow pace were identified and appropriate solutions in terms of improved funding of education, enactment of national policy on nanotechnology, curriculum development, international cooperation as well as human resource development among others were discussed.

“…Fresh yams are susceptible to be contaminated by pathogenic and spoilage microorganisms and are not easily stored due to their high water activity and nutrient content. It has been reported that the yam root rot disease caused by Fusarium moniliforme (F. moniliforme) are the major postharvest challenges in the availability of yam root tubers (Eze et al, 2016;Ezeonu et al, 2018;Ogundana & Dennis, 1981;Okigbo & Ikediugwu, 2000). Besides as the spoilage fungi of yam tubers, F. moniliforme can also produce mycotoxin of Fumonisin B 1 (FB 1 ) to contaminate the yam tubers.…”

Cold atmospheric plasma (CAP) as an emerging non-thermal technology holds great potential in food sterilization and biopolymer modification. This study investigated the antifungal effects of CAP against spoilage fungi in Chinese yam flour and its effects on the physicochemical and nutritional properties of Chinese yam flour. The results show that CAP treatment for 5–20 min achieved a microbial reduction of Fusarium moniliforme ranging from 0.56 to 2.40 log10 CFU/g at day 0 and 1.50 to 3.73 log10 CFU/g at day 9. The inactivation efficiency was increased with the CAP treatment time and storage time. For the physicochemical properties, CAP caused surface corrosion and formed aggregations on the surface of flour granules, as well as enhanced the absorption of carboxyl or carbonyl peak at 1730 cm− 1. The swelling power, starch solubility, and pasting viscosity of Chinese yam flour was increased after CAP treatment, while the endothermic enthalpy was decreased possibly due to the disruption of amorphous and crystalline structure of starch granules. A distinct color change was observed in CAP-treated Chinese yam flour, which became more bright and less yellow. The results of nutritional properties demonstrate that CAP caused a redistribution of dietary fiber components from insoluble to soluble fractions and changed the amino acids composition in Chinese yam flour. The SDS-PAGE analysis confirmed that CAP treatment could degrade or depolymerize the macromolecular proteins into small molecular subunits. Thus, CAP can be a promising technology to modify the physicochemical and nutritional properties of Chinese yam flour and ensure its microbial safety.
