Aims: To determine the effect of roasted soybean flour substitution on the chemical and sensory properties of maize flour snack (Aadun). Study Design: Multiple comparison test was performed on the data obtained using Duncan test Place and Duration of Study: Samples were prepared in Department of Food Science and Technology, Osun State Polytechnic, between August 2020 and November 2020. Methodology: Composite flours were developed from roasted maize and soybean to produce snacks (Aadun). Proximate, mineral, amino acid profile and sensory properties of the samples were determined using standard procedure. Results: The protein content of the sample ranged between 8.94–16.43% with sample with 40% soybeans having the highest value. The mineral content of the samples increased with increased addition of soybean. Total amino acid of the Aadun samples ranged between 64.81 and 83.42 g/100 g showing an increase as fortification with soybean flour increased. The sensory evaluation showed no significant differences (p>0.05) in the overall acceptability of all the snacks. Conclusion: The chemical properties of Aadun increased with addition of soybean flour. Addition of 10 % soybeans to the maize snack did not have significant effect on the taste, texture and overall acceptability.

The objective of this work was to produce biscuits from composite flour of wheat, coconut, and defatted fluted pumpkin seed and to evaluate the mineral bioavailability, amino acid profile and sensory properties of the composite biscuits. Wheat/coconut/defatted fluted pumpkin seed flours were blended in the ratio; 100/0/0, 80/10/10, 70/20/10, 60/30/10, 50/40/10, 40/50/10 and labelled as sample A, B, C, D, E and F respectively. Biscuits were baked with these composite flours using the creaming method. Lysine content ranged from 3.35-5.07g/100g, with sample F given significantly higher value followed by samples E (4.70g.100g) and D (4.33g/100g). All the essential amino acids increased significantly with increased substitution of coconut and fluted pumpkin seed flour, except phenyl-lanine and cysteine that decreased from 4.98 – 3.90 and 1.22 – 0.69g/100g respectively in sample A to E. Sample E gave higher total Ca, Fe, K and Zn of 26.89, 17.92, 86.02 and 2.82mg/100g respectively. Percentage bioavailability of Ca, Fe, Na, K and Zn were significantly higher in sample F with values of 59.67, 51.35, 58.22, 59.67 and 47.74% respectively. Sample E recorded the highest overall acceptability score of 6.38. This score was however not significantly different from scores obtained for samples A, B, C and D. Production of composite biscuits with 50/40/10% wheat/coconut/defatted fluted pumpkin seed flour is highly recommended.

Purpose The purpose of this study was to compare the physico-chemical properties and amino acid profile of three maize hybrid cultivars grown in Nigeria. Design/methodology/approach Two normal maize endosperm varieties, yellow SUWAN-ISR (YNM) and white ART/98/SW05-OB-WC (WNM), and one yellow QPM variety, TZE-POP-DT-STR-QPM (YQPM), were selected for the study. Physico-chemical properties, physical tests, proximate composition analysis, functional properties and characteristics and amino acid profile tests were carried out on the grains using standard methods. Findings Protein was significantly higher (p < 0.05) in YQPM (10.49 per cent) than in normal endosperm, YNM (8.83 per cent) and WNM (8.50 per cent). Amino acid profile of the grains revealed that total amino acid of YQPM (94.67 g/100 g of protein) and essential amino acid of YQPM (39.070) were the highest among the three, with highest significantly different value of tryptophan (0.388 g/100 g of protein) at p < 0.05. The cooking quality of YQPM was found to be better than the other two, with highest hydration capacity and increase in volume after cooking (90.8 ± 0.01 g/1000 grains and 147.53 ± 0.02 per cent). Originality/value YQPM will be highly beneficial in the tropics, where maize is grown as the major staple food to reduce hunger and malnutrition because of its amino acid balance and its better cooking quality.

Use Efficiency

In a cascade hydroponic system, the used nutrient solution drained from a primary crop is directed to a secondary crop, enhancing resource-use efficiency while minimizing waste. Nevertheless, the inevitably increased EC of the drainage solution requires salinity-tolerant crops. The present study explored the salinity-tolerance thresholds of basil to evaluate its potential use as a secondary crop in a cascade system. Two distinct but complemented approaches were used; the first experiment examined basil response to increased levels of salinity (5, 10 and 15 dS m−1, compared with 2 dS m−1 of control) to identify the limits, and the second experiment employed a cascade system with cucumber as a primary crop to monitor basil responses to the drainage solution of 3.2 dS m−1. Growth, ascorbate content, nutrient concentration, and total amino acid concentration and profile were determined in both experiments. Various aspects of basil growth and biochemical performance collectively indicated the 5 dS m−1 salinity level as the upper limit/threshold of tolerance to stress. Higher salinity levels considerably suppressed fresh weight production, though the total concentration of amino acids showed a sevenfold increase under 15 dS m−1 and 4.5-fold under 5 and 10 dS m−1 compared to the control. The performance of basil in the cascade system was subject to a compromise between a reduction of fresh produce and an increase of total amino acids and ascorbate content. This outcome indicated that basil performed well under the conditions and the system employed in the present study, and might be a good candidate for use as a secondary crop in cascade-hydroponics systems.

Orange Fleshed Sweet Potato

Breakfast strips were produced from different blends of orange-fleshed sweet potato (Ipomea batatas), plantain (Musa paradisiaca) and soybean (Glycine max) flours with substitution ratios of 100:0:0, 90:10:0, 90:0:10, 80:10:10, 70:15:15, 60:20:20 and 50:25:25 and labelled as samples A, B, C, D, E, F and G, respectively. The blends were evaluated for functional properties, total carotene, vitamins (B2 and B6) and sensory properties of the breakfast strips with a commercial breakfast food (Flakes) as control (sample H) . For the functional properties, the water absorption capacity decreased while the oil absorption increased with an increase in substitution levels of the soybean flour. The bulk density, solubility, swelling power and swelling volume were higher in sample A. The least gelation capacity maintained a constant rate of 4% across the blends. The moisture content of the strips ranged from 7.25-9.40%. The Ash contents were below 3% for all the blends. The protein contents increased with an increase in substitution with soybean flour while sample A - breakfast strips from 100% orange-fleshed sweet potato flour showed the highest value for fats (5.62%). The fibre content ranged from 0.69 to 5.14% and carbohydrate content reduced with an increased substitution with soybean flour (72.25-78.70%). The energy value ranged from 351.90-384.80 Kcal/100 g which was within the limit recommended for breakfast foods. Total carotene content increased with increased substitution with orange-fleshed sweet potato (15.18-33.56 mg/kg) which is significantly higher than the control at 0.75 mg/kg. The result of the sensory evaluation showed that the overall acceptability of the samples produced compared favourably with the control. Sample A and B showed a vitamin B2 of 4.70 and 4.00 mg/kg, respectively. However, the values decreased with increase in the addition of soybean while vitamin B6 increased with increase in soybean.

This study was conducted to determine vitamin A, B, C, b-carotene and amino acid profile in 18 genotypes and four grass pea (Lathyrus sativus L.) varieties which have low b-ODAP. Present results indicated that retinol, b-carotene, thiamine, riboflavin, niacin, pantothene, pyridoxine, folic acid and ascorbic acid ranged from 25.6 to 44.1 µg/kg; 240.8 to 410.1 µg/kg, 3.74 to 5.44; 1.86 to 2.76; 12.37 to 20.25; 14.43 to 22.41; 4.92 to 6.62; 4.04 to 6.77 and 33.4 to 58.2 mg/kg, respectively in seeds. In addition to, the amino acid profile of the genotypes differed significantly and total amino acid amounts were found to be 19.69 to 23.48 g/100 g seeds. A large and significant variation was observed among these genotypes with low b-ODAP content in respect to the quality of the nutrient content. This variability will be useful to breeders for utilization in grass pea improvement.

First Time

The majority of biochemical studies in corals has been focused on the lipidic composition and little attention has been given to the amino acid profile of these invertebrates. The objectives of this work were to investigate, for the first time, the temporal variations in the total amino acid (AA) composition of an octocoral, namely the sea penVeretillum cynomorium, and to evaluate possible interspecific differences in AA profile between this octocoral and hexacorals. The quantitatively most important AAs inV. cynomoriumcolonies were: glutamic acid, varying from 3.92 to 5.94% dry weight (dw) and representing around 14–15% of total AA content; aspartic acid (3.34–4.99% dw; 11–12%); and glycine (2.87–4.57% dw; 9–12%). On the other hand, the minor AAs were methionine (0.41–0.73% dw; 1–2%) and histidine (0.54–0.76% dw; 2%). Almost all AAs showed the same significant seasonal variations, with the highest values in February, second highest in October and the lowest in June. Some AAs, namely lysine, phenylalanine and methionine did not follow this trend and showed the major peak in October. Most of the AA variations seemed to be linked to changes in food availability and/or gametogenesis. Principal component analysis clearly separated the octocoral from the group of hexacorals, mainly due to the higher percentages of arginine, tyrosine and glycine inV. cynomorium, and valine, serine, histidine, isoleucine and alanine in hexacorallia species. We speculate that this differentiation possibly derived from physiological differences related to phylogeny, and was not affected by reproductive or environmental seasonality.
