“…This result is obviously because the protein content in white maize was not significantly different from PVA-biofortified maize. In contrast, Pillay et al found that PVA-biofortified maize had a higher protein concentration than white maize [60], whereas Oluba and Oredokun-Lache found that white maize had a significantly higher value than PVA-biofortified maize [62]. The reason for the differences seen in protein concentration could be attributed to genetic and/or environmental factors.…”

Biofortification of staple crops has a potential for addressing micronutrient deficiencies, such as vitamin A deficiency (VAD), which are prevalent in South Africa. The poor acceptability of provitamin A (PVA)-biofortified foods could be improved by combining them with other food items to produce modified traditional dishes. The nutritional composition of the dishes could also be improved by the modification. The study aimed to investigate the effect of replacing white maize and cream-fleshed sweet potato (CFSP)] with PVA-biofortified maize and orange-fleshed sweet potato (OFSP) on the nutritional composition of South African traditional dishes. The protein, fibre, total mineral (ash), lysine, and iron concentrations of the PVA maize phutu (traditional porridge) composite dishes (control), were not significantly different (P > 0.05) from those of white maize phutu composite dishes. However, the PVA concentration of PVA maize phutu composite dishes was higher than that of the white phutu composite dishes (P > 0.05). The OFSP had a significantly lower protein concentration, but a significantly higher (P > 0.05) fibre, ash, lysine, isoleucine, leucine, and PVA concentration, relative to the CFSP. The findings indicate that composite dishes in which white maize is replaced with PVA-biofortified maize, and switching over from CFSP to OFSP, would contribute to combating VAD in South Africa, and in other developing counties.

“…However, the molecule is the same, once supplied through a food matrix, the digestion and absorption rate in the gastrointestinal tract is lower [59]. This condition is extremely interesting and desirable for food products that can be consumed by people with chronic diseases such as obese and diabetics individuals [60][61][62][63].…”

Sweet Corn (<em>Zea mays L.</em>) is possibly the most important commercial cereal originating in the Americas. Mutant genes are responsible for sweetness. The purpose of this study was to evaluate the physicochemical and mineral composition of the “UENF SD 08” cultivar, super-sweet corn developed at Darcy Ribeiro Northern Rio de Janeiro State University (UENF) and registered in the National Cultivar Register of the Ministry of Agriculture, Livestock, and Supply and to compare its content to commercial super-sweet corn and field corn. Grain analyses were conducted at the Food Technology Laboratory, Phytotechnics Laboratory, and Animal Science Laboratory, UENF. The pH, total soluble solids, proximate composition, and mineral content were determined. In addition to the “UENF SD 08” cultivar, the “Tropical Plus®” cultivar, and the “UENF 506-11”, field corn cultivar were also studied. When comparing the mineral content, we observed there was not a great variability between the two super-sweet corn cultivars (“UENF SD 08” e “Tropical Plus®”). We highlight that both cultivars have higher soluble sugar concentration and less starch content for proximate composition. Therefore, having a cultivar adapted to the Northern Rio de Janeiro climatic conditions and knowing its nutritional characteristics is important for producers and individuals who will consume it, fresh or corn products.

“…In vitro studies have already demonstrated that phenolic substances have antimicrobial, antioxidant, antiviral, anti-inflammatory, and vasodilatory properties (Thirumurugan et al, 2018). For carotenoids, antioxidant properties, protection against oxidative damage to cellular components, prevention of cardiovascular diseases and cancer are described (Oluba & Oredokun-Lache, 2018). Therefore, the consumption of foods that are sources of these substances results in health benefits and contributes to an improved quality of life (Castejón-Veja et al, 2020).…”

The objective of this work was to determine the total carotenoids, total phenolics, and antioxidant activity of 'UENF SD 08' (super-sweet corn) and to compare them with those of 'UENF50611' (field corn). The total carotenoid content was determined according to Rodriguez-Amaya, the total phenolic content by the Folin-Ciocalteau method, and the antioxidant activity by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging method. For 'UENF SD 08', the average values were: 936.76±16.34 µg 100 g−1 for carotenoids, 346.0±3.80 mg 100 g−1 for phenolics, and 45.53±0.01% for antioxidant activity. For UENF50611, the average values were: 1,173.38±21.66 µg 100 g−1 for carotenoids, 563.33±7.97 mg 100 g−1 for phenolics, and 59.82±0.11% for antioxidant activity. UENF50611 showed a higher antioxidant activity observed due to its higher levels of carotenoids and phenolic compounds; however, the values observed for the 'UENF SD 08' super-sweet corn are within the ranges already described in the literature. 'UENF SD 08' contains a lower concentration of carotenoids and phenolic compounds than 'UENF50611', its nonmutant genetic background. However, the super-sweet corn 'UENF SD 08' has agronomic advantages, is considered a source of the evaluated secondary metabolites, and its consumption can contribute to a diet with a higher content of antioxidants.
