“…High HCN is capable of inhibiting cytochrome C oxidase, which can lead to cytotoxic hypoxia [38]. The high level of HCN may be due to the fact that during starch isolation, heat treatment was not involved, as antinutrients are heat labile and deactivated during processing protocols requiring heat treatment [39]. Tannins was higher in C. bicolor (254.97±0.42 mg/100 g) than D. dumentorum (144.71±0.06 mg/100 g).…”

“…It ranged from 0.24±0.06 mg/100 g to 4.66±0.05 mg/100 g, with D. dumentorum having the higher level. Higher values have been reported for tubers, legumes and cereals [12,[35][36][37], while phytate level of 0.05±0.00 mg/100 g has been reported for Dioscorea cayenensis [39]. Phytates are known to bind mineral nutrients in the digestive tract leading to mineral deficiency in the body [43].…”

Starch samples from the wild species of cocoyam (Caladium bicolor (Aiton) Vent.) and three leaf yam (Dioscorea dumentorum (Kunth) Pax.) found abundantly in the south and eastern regions of Nigeria, were characterized for their physicochemical, functional and antinutrient properties. C. bicolor had higher amylose (17.68%), carbohydrate (83.57%) and ash (2.85%) than D. dumentorum. Moisture, crude lipid, protein and fibre ranged between 7.56 to 10.29%, 0.12 to 0.15%, 0.11 to 0.13%, and 2.85 to 3.39%, respectively. The starches exhibited promising functional properties with D. dumentorum having higher dispersibility (64.85%), solubility (73.99%) and oil absorption capacity (2.15 g/g). Onset (To), midpoint (Tm), and conclusion (Tc) gelatinization temperatures ranged between 63 to 79 °C. Peak, breakdown and setback viscosity were higher in D. dumentorum than C. bicolor. Moisture sorption behavior indicated increased hygroscopy with exposure time. The starches had high antinutrient levels, with D. dumentorum having higher levels of HCN and oxalates. In addition, infrared (IR) spectra of both starches were similar. Taken together, these properties suggest the suitability of these starches for non-food applications due to their high antinutrient contents.

“…It is widely accepted that simple and inexpensive processing techniques are effective methods of achieving desirable changes in the composition of plant materials [75]. It has been observed that processing significantly improved macronutrients and energy content with significant reduction in anti-nutrient concentration of products making them suitable for consumption [76]. Bora [70] and Fereidoon [71] reported that processing method like fermentation and thermal treatment are very effective in inactivating some anti-nutrients; due to their particular protein nature, protease inhibitors may be easily denatured by heat processing thereby effectively inactivating them, which is associated with growth inhibition and pancreatic hypertrophy.…”

Mineral contents and amino acid and fatty acid profiles of Xylopia aethiopica fruits from Enugu State, Nigeria were evaluated in this study. The amino acid and fatty acid profiles, phytochemical, proximate, mineral, anti-nutrient and vitamin contents of X. aethiopica fruits were determined using standard methods. The proximate, vitamins, phytochemical, anti-nutrient of both the crude and methanol extract were determined while the mineral and amino acid profile were determined in the crude fruit powder while fatty acid profile was determined in the oil extract of the fruits. Results show that the predominant amino acids present include proline, alanine, norleucine, isoleucine, glycine, threonine, cysteine, methionine, and tryptophan. Also, the most abundant fatty acids include arachidonic acid, dihomoÏ’-linolenic acid, palmitic acid, caproic acid, linoleic acid, palmitoleic acid, stearic acid and myristic acid. The mineral contents of X. aethiopica fruits detected in high amount were calcium, iron, potassium and magnesium. Sodium, zinc and manganese were detected in lower amounts. However, lead, silicon, nickel and chromium were not detected. The result of the proximate analysis shows moisture, total protein, crude ash, total fat, crude fibre, and carbohydrate contents. Anthraquinone was not detected in both crude and methanol extract of the fruit. The concentration of flavonoids, steroids, anthocyanin and terpenoids were significantly (p < 0.05) higher in crude sample when compared with methanol extract. The levels of carotenoid and glycosides were significantly (p < 0.05) higher in the methanol extract when compared with crude sample. Vitamins B1, B3, B6, B9, B12, C and E levels were significantly (p < 0.05) higher in crude extract when compared with methanol extract. However, vitamin A content was significantly (p < 0.05) higher in methanol extract when compared with crude extract. Results obtained showed that X. aethiopica fruits are rich in nutrients and that methanol extraction decreased the anti-nutrient contents of the fruits thereby increasing the bioavailability of the nutritive factors. However, the quantities of some of the nutritive factors were reduced after extraction

The data presented in this article are related to research article titled “Effects of processing methods on nutrient and antinutrient composition of yellow yam (Dioscorea cayenensis) products” (Adepoju et al., 2016) [1]. This article documented information on nutrient and antinutrient composition as well as nutrient retention of Dioscorea cayenensis products. Fresh Dioscorea cayenensis tubers obtained from Bodija market were prepared into raw sample and local delicacies and analysed for proximate, mineral, vitamin and antinutrient composition using AOAC methods [2]. Data obtained were analysed using ANOVA, and level of significance set at p<0.05. Processing significantly improved macronutrients and energy content of yam products, and led to significant reduction in values of all antinutrient content of the products (p<0.05).
