“…These results indicated that conjugated and bound phenolics were strongly related throughout the entire developmental stages and grain filling. In cereals, the majority of phenolics are concentrated in the bound form (Ndolo & Beta, 2014; Sosulski et al., 1982; Van Hung, 2016; Mariana Horvat et al., 2020; Zavala‐López et al., 2018); however, there is not much information regarding the distribution of different phenolic fractions, especially during early stages of kernel development. To our best knowledge, this is the first report of changes in conjugated phenolics during maize kernel development and their relation to bound phenolics.…”

A comprehensive study was performed to investigate the kernel phenolics content and profile of a broad range of maize inbreds varying in disease resistance to gibberella ear rot. Three phenolic fractions (soluble free, soluble conjugated, and insoluble bound) at different kernel developmental stages in two growing seasons were analyzed. The phenolics content and profile revealed a genotype dependency. The highest amount and diversity of phenolics were at day 11 after self‐pollination in both growing seasons. This was confirmed by a distinctive PCA biplot clustering of phenolics at day 11 compared to other harvesting days for all fractions. A strong negative correlation was found between the conjugated and bound phenolics in both growing seasons (in 2016, r = 0.93, p < 0.0001; and in 2018, r = 0.94, p < 0.0001). In both growing seasons, the main phenolic compounds in the free, conjugated, and bound fractions were chlorogenic acid, caffeic acid, and t‐ferulic acid, respectively. Comprehensive results were presented for how the phenolics evolved over the period of kernel development and how their content changed. The PCA‐biplot analysis revealed different patterns of clustering for phenolic associations in different fractions as well as in different growing seasons, reflecting the evolution process of individual phenolics during kernel filling period. Overall, genotypes with higher disease resistance possessed higher phenolics in the bound and conjugated fractions at blister stage. This study provides a useful resource of maize inbred phenolics profiles that could be applied in future breeding efforts.

“…Laboratory tests have been performed to assess the bioaccessibility of thiamine, niacin and phenolic acids obtained from various aleurone fractions of durum wheat cultivars. The results have shown that the bioaccessibility of basic phenolic compounds and the studied vitamins is higher in the inner part of the aleurone layer than in its outer part or in unfractionated bran (Zaupa et al, 2014). The data of the research carried out in vitro, in vivo and on humans have demonstrated that phenolic compounds possess powerful antioxidant properties (Shi et al, 2014).…”

Substances inhibiting or preventing oxidative damage in the target molecule are called antioxidants. It has been shown that antioxidants are substances that contribute to the prevention of a number of serious human diseases, and antioxidant activity is one of the important parameters for the quality of food products and ingredients. Phenolic compounds are of greatest importance for this review. It is now established that whole grain cereals contain a large number of bound polyphenols. It is known that cereals have high nutritional value, contain unsaturated fatty acids, basic mineral elements, proteins and β-glucans, and are also characterized by the presence of various chemical substances with antioxidant properties. In recent years, work has begun in some Western countries to study the content of antioxidants in various grains. In Russia, only a small amount of work has been devoted to the study of these important chemical compounds in grain crops. It should be noted that, although these species are considered to be one of the main components of human nutrition, research in the field of determining their antioxidant activity has not been sufficiently carried out. In order to attract the attention of plant growers, plant breeders, plant physiologists, geneticists and biotechnologists, we offer a review of current literature.

“…Notable researchers Ojediran et al (2020);and Kanengoni et al (2004) have shown that cassava peel and maize cob can be used to replace maize up to 50%. The optimal amount of dried cassava peel meal and dried maize cob meal to substitute for maize in pig diets is not well documented (Zavala-López et al, 2018). Evaluating the effect of cassava peel-maize cob meal (CP-MC) mixture will also help to maximize the potential in the environment, help to formulate the least ratio feed, and help to increase the production of animal protein.…”

A 90-day trial was carried out to evaluate the performance and carcass characteristics of grower pigs fed enzyme-supplemented dried cassava peel-maize cob composite meal (CP-MC). A total of 36 crossbreed male grower pigs (Large white) of about 16 weeks old with an initial body weight of 20.31 ± 0.61 kg-1 were randomly allotted into four groups of nine animals per treatment. Each treatment was further divided into three replicates consisting of three pigs in a completely randomized design. Pigs in treatment 1 were fed 0% CP-MC while CP-MC was used to replace maize at 40% (T2), 50% (T3), and 60% (T4). Diet was adequate in all nutrients, and clean water and feed were offered ad libitum. Results on growth performance showed that average daily weight gain was higher in T4 (0.34 kg) and T3 (0.33 kg), intermediate in T2 (0.26 kg), and lower in T1 (0.23 kg) (p < 0.05). Similarly, the best feed conversion ratio was found among pigs in T4 followed by T3, T2, and T1 (p < 0.05). Conversely, average daily feed intake was not influenced by the treatments (p > 0.05). Dressing percentages varied from 61.60-71.94% were significantly (p < 0.05) different among the treatments. Weights of the head, belly, limbs, back fat thickness, kidney liver, lungs, and spleen were significantly (p < 0.05) different among the treatments. In conclusion, the replacement of maize with CP-MC at 60% improved the weight of pigs without compromising the performance of animals.
