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.

Amino Acid Profiles

The Objectives of the Study: To evaluate the Antinutritional components, Amino acid profiles and the physic-chemical properties of Hura crepitan (Sand box) seed. Design of the Study: This study was structured to fit into using a combination of T-test and one way Analysis of Variance (ANOVA) to evaluate the data obtained from the laboratory analysis. Place and Duration of Study: This research work was done at the Department of Food Science and Technology Laboratory, Federal University of Technology, Owerri, Nigeria, between May 2019 and November 2019. Methods: The mature dry fruits of the Hura crepitan seeds were harvested from the plants on Federal University of Technology Owerri, Imo State campus. The Hura crepitan seeds were sorted in order to remove dirts and foreign other foreign contaminants. The cleaned seeds were divided into four portions and stored in separate glass containers for further processing. The first portion of the seeds were dried at 60°C in Gallen Kamp moisture extraction oven for 6 hours at and pulverised in a Monilex blended into flour, some seeds were boiled while some portions were roasted and processed into fine flour and subsequently subjected to analysis to evaluate the antinutritional contents, amino acid s as well as determining the physic-chemical properties of the samples. Results: The results obtained suggested that the anti-nutrients in the raw seed-flour were flavonoids with 17.50%, alkaloid (6.20%), tannin (5.24%), and cyanogenic glycoside (1.76%). Fermentation and moist cooking were found to be more effective in the reduction of the anti-nutrients in the Hura crepitan seeds. The amino acid profiles were evaluated, and twenty amino acids were identified in the seed flour. The three major ones implicated were arginine (3.25 g/100 g in cooked and 8.05 g/100 g in fermented), glutamic acid (6.05 g/100 g in cooked and 10.2 g/100 g in fermented) and valine (8.03 g/100 g in raw and 8.58 g/100 g in fermented). The limiting amino acid is methionine with a chemical score of 44.52%. the physicochemical properties of the sandbox seeds evaluated suggested that the free fatty acids values ranged from 3.60% to 6.03% and there were no significant differences (P>0.05) among the samples, the iodine value ranged from 104.94% to 126.90%, the peroxide value for the sample varies between 2.96% to 44.81%. Conclusion: This study suggested that the Hura crepitan seed contains appreciable amounts of essential amino acids as well as having good physicochemical properties while the use of moist heat and/or fermentation can reduce the antinutritional components to the bearest minimum. Hence, can be utilized some areas of food industries where protein (amino acids) are critically required.

The objective of this work was to produce local (Madiga) bread from the blend of wheat and fluted pumpkin seed flour and to evaluate the nutrient composition and sensory properties of enriched Madiga produced from these flour blends. Defatted fluted pumpkin seed flour was used to substitute wheat flour at the following; (Wheat to Fluted pumpkin seed flour ratio); 100:0 (control), 90:10, 80:20, 70:30, 60:40%, 50:50, and labelled as samples A, B, C, D, E, and F, respectively. The ash content ranged from 1.20 – 2.55%, with sample A given significantly lower ash content (1.20%) than those of the enriched Madiga. Significantly higher ash values of 2.55%, 2.44% and 2.39% were recorded in samples E, F and D, respectively. There was no significance in the fat content of samples A and B. Percentage protein ranged from 6.79% – 9.36%. The crude protein content of all the enriched Madiga samples were significantly higher than that of the control, Crude fiber content ranged from 0.91% – 1.82%, with sample C given significantly higher value of 1.82% followed by samples D and F. Control local Madiga gave significantly higher carbohydrate content of 74.31%. The energy value per kcal/100g for samples B, C, D, E and F were 258.62, 284.16, 296.07, 296.96 and 278.81, respectively. Samples B and C received significantly higher value of 4.70 and 4.05, respectively, keeping these samples in the ‘sweet’ to ‘very sweet’ range. Samples B and C received significantly higher overall acceptability and were scored 3.85 and 3.70, respectively. These values were however, not significantly difference from 3.33 and 2.93 as scored in samples D and E, respectively. Substitution of wheat flour with 10, 20 and 30% defatted fluted pumpkin seed flour was effective in producing enriched Madiga bread, thus recommended.

Objective: Amino Acid, phytochemical and Acute Toxicity levels (LD50) of date palm seeds were evaluated in the present study. Seeds of five varieties of date palm fruits at mature stage were manually isolated, soaked in water, oven dried and milled into flour. Five varieties of Deglet Nour, Lulu, Bomaan, Fardh and Barhe were used. Results: The seeds contained all the essential and non-essential amino acids. Leucine was in highest quantity of (10.10-12.02g/100g protein) while Glutamic acid had the highest amount of 18.62-21.04g/100g protein. Significant amount of oxalate (6.31-8.89 mg/100g), phytate (5.15-8.37mg/100g), Hydrogen Cyanide (3.26-5.34mg/100g), Tannin (3.40-6.31mg/100g), Saponin (2.29-4.36mg/100g) were found in all the five varieties. The LD50 tests outcome suggests that the samples were completely free from any form of toxicity since all treated experimental animals showed no sign of toxicity, rather looked physically healthy and emotionally stable all through the period, even at 5000mg/kg body weight of the samples. Conclusion: The seeds were found to be edible and safe. They can be used in formulating diets. Conventional processing methods will ensure the elimination of the anti-nutrients.The seed flour can therefore be used as composite with other flours and hence find application in food industries such as bakery industry.

Almond Oil

Almonds harvesting, along with precleaning, hulling, shelling, and sorting, generate recoverable co-products such as double, malformed, or damaged almonds. The common way that generates more benefit is the extraction of almond oil for food and cosmetic uses. The aim of this study is to compare composition and nutritional value of almond meals of the main varieties from eastern Morocco, Marcona (M), Fournat de Breznaud (FNB), FerragnesandFerraduel (FF) and Beldi a local ecotype (B), during three consecutive crop years (2016-2018). Significant differences were observed, which mainly concern the residual oil in almond cakes and especially their fibres, sugars, and proteins. Differences depend on the quality of the raw material and the effects of the crop year on the variety. Besides, from a nutritional point of view, analysed almond meals still contain significant amounts of residual oil and the major constituents of almond seeds (sugars, fibres, and proteins). The amino acid profile presents eight essential amino acids (Cysteine, Methionine, Isoleucine, Leucine, Phenylalanine, Tyrosine, and Lysine Valine) and the Protein Digestibility Corrected Amino Acid Score (PDCAAS) ranges between 24.78% for (M) and 62.17% for (FF). We conclude the analysed almond meals present interesting nutritional values as a specific ingredient for gluten-free culinary preparations and light foodstuffs.

Fluted pumpkin (Telfairia occidentalis) seed is a perennial plant that belongs to the family of Cucurbitaceae. Several nutritional values of the seeds have been reported. In this present study, thirty rats (average weight= 133 g ± 1.25 g) were randomly allocated to 5 groups of 6 rats each and placed on a conventional diet supplemented with groundnut meal (control), unprocessed fluted pumpkin seed flour (UF_Diet), boiled fluted pumpkin seed flour (BF_Diet), germinated fluted pumpkin seed flour (GF_Diet), and soaked fluted pumpkin feed flour (SF_Diet) for 28 days after which animals were sacrificed and blood samples collected for biochemical and haematological analysis. Results revealed that processing improved the protein content of the seed flours. The aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) range from 210.70±2.14 to 517.5±5.39 U/L, 60.6±0.30 to 386.3±3.53 U/L, and 221.7±1.21 to 328.4±3.31 U/L respectively. Processing significantly decreased (p< 0.05) the creatinine content of rats fed supplemented fluted pumpkin seed flours when compare with the control and unprocessed groups. The hematological parameters were also significantly (p<0.05) improved by the dietary treatments. The result of this study revealed that germination, soaking, and boiling were effective processing methods for improving the nutritive values of fluted pumpkin seed meals

The perturbation in plasma free amino acid metabolome has been observed previously in diabetes mellitus, and is associated with insulin resistance as well as the onset of cardiovascular disease in this population. In this study, we investigated, for the first time, changes in the amino acid profile in a group of people with and without type 2 diabetes (T2D) with normal BMI, from Jordan, who were only managed on metformin. Twenty one amino acids were evaluated in plasma samples from 124 people with T2D and 67 healthy controls, matched for age, gender and BMI, using amino acids analyser. Total amino acids, essential amino acids, non-essential amino acids and semi-essential amino acids were similar in T2D compared to healthy controls. Plasma concentrations of four essential amino acids were increased in the presence of T2D (Leucine, p &lt; 0.01, Lysine, p &lt; 0.001, Phenylalanine, p &lt; 0.01, Tryptophan, p &lt; 0.05). On the other hand, in relation to non-essential amino acids, Alanine and Serine were reduced in T2D (p &lt; 0.01, p &lt; 0.001, respectively), whereas Aspartate and Glutamate were increased in T2D compared to healthy controls (p &lt; 0.001, p &lt; 0.01, respectively). A semi-essential amino acid, Cystine, was also increased in T2D compared to healthy controls (p &lt; 0.01). Citrulline, a metabolic indicator amino acid, demonstrated lower plasma concentration in T2D compared to healthy controls (p &lt; 0.01). These amino acids were also correlated with fasting blood glucose and HbA1c (p &lt; 0.05). Glutamate, glycine and arginine were correlated with the duration of metformin treatment (p &lt; 0.05). No amino acid was correlated with lipid profiles. Disturbances in the metabolism of these amino acids are closely implicated in the pathogenesis of T2D and associated cardiovascular disease. Therefore, these perturbed amino acids could be explored as therapeutic targets to improve T2D management and prevent associated cardiovascular complications.

The objective of this work was to evaluate the Amino Acid profile/score and In-vitro protein digestibility of composite biscuits produced from blends of Wheat flour (WHF), African breadfruit flour (ABF)and Moringa seed flour(MSF) at the following ratios (Sample A: WHF 100%: ABF 0; MSF 0, B= WHF 77.5%:ABF 20%: MSF 2.5%, C=WHF 75%: ABF 20%: MSF 5.0%, D= WHF 72.5%: ABF 20%: MSF 7.5%. E = WHF 70%: ABF 20%: MSF 10%, F = WHF 90%: ABF 0: MSF 10%, G = WHF 80%: ABF 20%: MSF 0). The most predominant Amino Acid in ABF was glutamic (12.27 g/100 g) followed by Aspartic and lysine, with values of 8.96 g/100 g and 6.55 g/100 g, respectively. Glutamic Acid content of the biscuits ranged from 10.96 g/100 g – 12.96 g/100 g, with sample B giving significantly higher value. Substitution with MSF resulted in decreasing glutamic acid content levels in the formulated biscuits, while lysine, phenylalanine and Isoleucine improved with the addition of 10% Moringa seed flour. Amino acid Scores of the biscuits using Hen egg as standard showed that whole egg had a higher amino acid score except glycine (1.04 – 1.25). Percentage In-vitro protein digestibility ranged from 10.64% - 47.33%, showing that addition of moringa seed flour and African breadfruit flour improved digestibility values from 10.64% to 47.33% for sample E with the control sample (wheat flour biscuit) being significantly lower. Substitution with ABF and MSF improved protein digestibility of the produced biscuits. Also, the Amino acid scores of the formulated biscuits were higher than the FAO recommended daily dietary requirements for Amino acids.
