Abstract

Purpose

The purpose of this paper is to provide information on how processing technique affects some of the nutrient in cashew nut. It aims to guide processors of the nut on the processing techniques that can retain or minimize losses of nutrients during processing.

Design/methodology/approach

Cashew nuts were obtained from commodity support service that procure cashew for export. Standard methods and techniques of processing (boiling, fermentation, germination, roasting) were employed. Standard Association of Official Analytical Chemist methods were used for analysis.

Findings

Cashew nut is low in deleterious elements and processing methods (boiling and fermentation) techniques reduced them. The energy values ranged from 25‐27.38 kJ/g. The nut contains micro‐ and macronutritive elements that can effectively supplement daily requirement of man especially potassium. Processing reduced some of the essential mineral elements. Cashew nut may be used to improve low protein diet.

Research limitations/implications

Processing was carried out using locally available materials. Fermentation was not controlled.

Practical implications

Cashew nut can be included in low protein diet, it can improve mineral intake and deleterious elements pose no threat to its consumption.

Originality/value

The paper provides information on processing effect on cashew nuts which had not been reported in literature, hence, provides data base information.

This study was aimed to develop and evaluate nutritional efficacy and bio-efficacy of food products from plantain, soycake, rice-bran and oat-bran flour.

Abstract

Purpose

This study was aimed to develop and evaluate nutritional efficacy and bio-efficacy of food products from plantain, soycake, rice-bran and oat-bran flour.

Design/methodology/approach

The flour samples were blended as follows: plantain 70% and soycake 30% (PS); plantain 65%, soycake 30% and rice bran 5% (PSR); plantain 65%, soycake 30% and oat bran 5% (PSO); and plantain 60%, soycake 30%, rice bran 5% and oat bran 5% (PSRO). Antioxidant and nutritional properties of the blended foods and controls (100% plantain and Cerolina) were determined.

Findings

Protein (16.2–19.4 g/100g) and biological values (98.5–99.3%) of the food samples were significantly (p = 0.03) higher than 100% plantain (5 g/100g, 31.6%) and Cerolina (17.9 g/100g, 98.3%). Pack cell volume (36.2–42%), serum protein (7.3–9.3 mg/dL), urea/creatinine (1.1–2.8) and aspartate-aminotransferase/alanine-aminotransferase ratio (0.9–1) of the foods were significantly (p = 0.03, 0.01, 0.02 and <0.01, respectively) higher than 100% plantain (28%, 1.6 mg/dL, 4.6 and 0.8) and Cerolina (46%, 4.9 mg/dL, 3 and 0.73). In vivo antioxidant activity of the food samples decreased from PSRO to PSO, PSR and PS, respectively and were higher than control samples. Nutritional performance of formulated foods in rats was similar to that of Cerolina, but higher than in 100% plantain. Cerolina and 100% plantain were rated higher in overall acceptability than formulated foods; however, PSO was most preferred followed by PSRO for the formulated foods.

Originality/value

The study established that PSRO was rated best in terms of nutrition, growth performance and antioxidant activities. Hence, this food may be suitable as functional food to prevent malnutrition and oxidative stress.

Abstract

Purpose

The study aims to investigate the potential of green immature soybean among Nigeria soybean varieties as human food.

Design/methodology/approach

Five Nigeria soybean varieties were harvested at 90 days old. The fresh green immature soybean seed were evaluated for chemical composition, physical and sensory characteristics. The physical characteristics looked into seed size (breadth and length), weight, seed colour, hull thickness and percentage of hydration. The chemical composition was compared to mature soybean seeds while the sensory attributes were compared to fresh green peas.

Findings

The raw mature soybean (RMS) was significantly higher and lower in chemical composition and anti‐nutritional factors respectively. The highest moisture content ranges from 62.8 per cent in TGX 1019‐2EB to 65.4 per cent in TGX 1485‐1D. The protein content (15.3 per cent) was highest in TGX1485‐1D and lowest value in TGX1448‐2E. The level of tannin was significantly higher in TGX1448‐2E and 923‐2E while trypsin inhibitor was significantly (p<0.05) higher in TGX1440‐1E and TGX1485‐1D. TGX1485‐1D had superior physical characteristics to other immature varieties with significant (p<0.05) higher value for breadth, length and height. The hull thickness of the seeds was within 0.01 to 0.05 and the percentage of hydration ranges within 5.5 to 6.8 per cent. All varieties had a green colour for the seed coat. Overall sensory acceptability of TGX TGX1440‐1E, 1485‐1D and 1019‐2EB compared favourably well with green peas used as control for sensory evaluation.

Originality/value

This study could help to identify the potential of some Nigerian soybean cultivars for production for use as a source of vegetable in the diet and also provided valuable information for further improvement of soybean for food uses.

Abstract

Purpose

The objectives of this study are to develop low cost weaning food for the economically disadvantaged nursing mothers and also to prevent protein energy malnutrition among the infants in Nigeria.

Design/methodology/approach

The blends (sweet potato and soybean flour) were prepared (homogenously) in the ratio of 90:10, 80:20, 70:30, 60:40 and 50:50 of sweet potato and soybean respectively. Triplicate samples of each blend were analyzed for moisture, fat, protein (N × 6.25), crude fiber and ash. Total lipid was estimated by petroleum ether extraction. Carbohydrate content was estimated by difference. Gross energy was determined. Water absorption capacity and bulk density were determined using standard procedures. The pasting characteristics of the flours were evaluated using a standard procedure. The sensory evaluation was carried out on the following parameters: taste, appearance, aroma, mouth (texture), colour and overall acceptability by a panel of ten members using a nine‐point hedonic scale.

Findings

The results of nutritional composition of the supplements showed protein 11.2–33.72 per cent, carbohydrates 42.91–76.51 per cent, fat 3.10–12.78 per cent, energy values 329.5–366.74 kcal/100 g and appreciable quantities of P, Zn, Fe, Mg, Ca, K and Na. The soy‐sweet potato flours had peak viscosity values between 180–365 BU. These values increased when cooled to 50°C, (420–760 BU). Results of this study showed that at 30 per cent soy flour supplementation, the meal could meet satisfactorily the recommended dietary allowances (RDA) for children of 1–3 years old, and that the developed soy‐sweet potato diets were nutritious, inexpensive and can easily be prepared from locally available raw food materials by using simple domestic processing techniques.

Originality/value

Evidence has shown that the cost of commercial weaning formula is very high and most of the low‐income family cannot afford to purchase this commercial weaning food and for such people an alternative low cost weaning formula is helpful.

Abstract

Purpose

The purpose of this paper is to develop and implement a general sensor model under normal and abnormal operational conditions including nine functional categories (FCs) to provide additional tools for the design, testing and evaluation of unmanned aerial systems within the West Virginia University unmanned air systems (UAS) simulation environment.

Design/methodology/approach

The characteristics under normal and abnormal operation of various types of sensors typically used for UAS control are classified within nine FCs. A general and comprehensive framework for sensor modeling is defined as a sequential alteration of the exact value of the measurand corresponding to each FC. Simple mathematical and logical algorithms are used in this process. Each FC is characterized by several parameters, which may be maintained constant or may vary during simulation. The user has maximum flexibility in selecting values for the parameters within and outside sensor design ranges. These values can be set to change at pre-defined moments, such that permanent and intermittent scenarios can be simulated. Sensor outputs are integrated with the autonomous flight simulation allowing for evaluation and analysis of control laws.

Findings

The developed sensor model can provide the desirable levels of realism necessary for assessing UAS behavior and dynamic response under sensor failure conditions, as well as evaluating the performance of autonomous flight control laws.

Research limitations/implications

Due to its generality and flexibility, the proposed sensor model allows detailed insight into the dynamic implications of sensor functionality on the performance of control algorithms. It may open new directions for investigating the synergistic interactions between sensors and control systems and lead to improvements in both areas.

Practical implications

The implementation of the proposed sensor model provides a valuable and flexible simulation tool that can support system design for safety purposes. Specifically, it can address directly the analysis and design of fault tolerant flight control laws for autonomous UASs. The proposed model can be easily customized to be used for different complex dynamic systems.

Originality/value

In this paper, information on sensor functionality is fused and organized to develop a general and comprehensive framework for sensor modeling at normal and abnormal operational conditions. The implementation of the proposed approach enhances significantly the capability of the UAS simulation environment to address important issues related to the design of control laws with high performance and desirable robustness for safety purposes.

The purpose of this study is to assess the protein (biological) quality of pecan and pine nuts supplemented diets in male Wistar albino rats.

Abstract

Purpose

The purpose of this study is to assess the protein (biological) quality of pecan and pine nuts supplemented diets in male Wistar albino rats.

Design/methodology/approach

A randomized and controlled study (45 d) was conducted in male Wistar albino rats (n = 60) comprising six groups, namely, control (Cc), control with 1% cholesterol (CC1), Pecan group (Pe), Pecan group supplemented with 1% cholesterol (Pi1), Pine group supplemented with 1% cholesterol (Pi1). Protein quality of supplemented diet/s was assessed in terms of various biological indices.

Findings

Pe and Pi groups exhibited normal growth when compared with Cc. Despite showing higher feed and protein intake, Pe and Pi groups exhibited significantly (P = 0.023) lower weight gain than Cc. There was no significant difference between the protein efficiency ratio (3.8 ± 0.2 and 3.7 ± 0.2), apparent protein digestibility (81.5 ± 2.2 and 80.5 ± 2%), true protein digestibility (90.6 ± 1.1 and 88.5 ± 3.5%) and biological value (BV) (75.6 ± 0.9 and 72.6 ± 0.9%) of Pe and Pi groups, respectively. Pe group presented considerably higher net protein utilization (68.5 ± 1.4 vs 64.4 ± 0.8%) and protein retention efficiency (34.8 ± 1.1 vs 31.2 ± 1.3%) than Pi group. Overall, pecan-based diet displayed superior biological quality over pine nut. Antinutrients present in the nuts did not show any major negative effect on the growth, digestibility and bioavailability of the nutrients in rats. BV ranging from 72.6% to 75.6% suggested a satisfactory quality of experimental nut-based diets.

Research limitations/implications

Further investigation of pecan and pine nuts consumption to examine the potential benefits and associated mechanisms of action is warranted which would aid in a better understanding and to establish nutritional recommendations.

Originality/value

Overall, the exploitation of pecan and pine nut flours for the development of value-added food products is favorable from a nutritional point of view.

The paper assesses the role of natural resource rents in Nigeria's economy through the channel of institutional quality.

Abstract

Purpose

The paper assesses the role of natural resource rents in Nigeria's economy through the channel of institutional quality.

Design/methodology/approach

The analysis is done with the use of autoregressive-distributed lag (ARDL) bounds testing approach to cointegration, vector error correction model (VECM), Granger causality test and cointegrating regression over the period 1996–2019.

Findings

Findings support the notion that overreliance on natural resources could exacerbate the growing number of dysfunctional economic outcomes in the country. The study confirms that a mix of weak governance quality and natural resource rents could have a negligible effect on economic growth and possible retardation impact on the economy in the long run as well as in the short run. The evidence further reveals that there is unidirectional causality running from the interaction term to growth, suggesting that growth trajectory could be jointly determined by natural resource rents and the quality of institutions.

Originality/value

The divergent arguments associated with the mechanisms of resource curse in each of the resource-rich countries offer ample support for the contention that economic outcomes in resource-abundant states may not be a product of resource windfalls per se, but rather the quality of governance or ownership structure. Hence, the ultimate aim of the analysis is to further understanding on the link between resource rents and growth in Nigeria via governance channel.

The article examines the possible long-run and short-run impact of regulatory quality on stock market performance in Nigeria for 1996–2019 period.

Abstract

Purpose

The article examines the possible long-run and short-run impact of regulatory quality on stock market performance in Nigeria for 1996–2019 period.

Design/methodology/approach

The study adopts autoregressive distributed lag (ARDL) bounds test and cointegrating regression techniques.

Findings

Findings reveal that regulatory quality positively and significantly influences the performance of stock market, which strengthens the view that market-enhancing governance can engender an improvement in stock market performance. The study further demonstrates that quality of the regulatory environment is a critical component of market operations, since the improvement of the operation of stock market performance depends on appropriate policy measures, which could be the outcome of improved governance.

Practical implications

It is suggested that, while improving the institutional environment is a challenge to regulators, there is need for strong and effective regulatory mechanism to enhance the development of stock market in the country.

Originality/value

Based on the two competing hypotheses and limited attention, previous studies accorded the role of regulatory quality in the performance of stock market in the context of Nigeria. This study assessed the gap in the literature by taking the task of validating the impact of regulatory quality on stock market development.

Abstract

Purpose

The main goal of the study is to explore the long run relationship between public debt and domestic investment in West Africa. Essentially, a study of this nature is to proffer major inroads into addressing low investment levels plaguing the region and securing critical fiscal policy measures.

Design/methodology/approach

The study examines the long-run relationship between public debt and domestic investment in 13 West African countries between 1986 and 2018 with the use of Panel Dynamic Least Squares (DOLS) and Panel Fully Modified Least Squares (FMOLS), and causality test based on Toda and Yamamoto.

Findings

Public debt (% of GDP) and external debt stocks have an insignificant effect on domestic investment in the long run, suggesting the negligible effect of public debt on the level of investments in the region. Further evidence shows that domestic investment Granger causes public debt indicators, implying that there is unidirectional causality. This suggests that any investment-generation policy could engender a rise in public borrowing, although such public loans might not be effective when there is pervasive mismanagement of public funds, as public debts need to be well managed for ensuring improved investment.

Research limitations/implications

The study suggests that maintaining a strong and effective debt-investment nexus requires fiscal consolidation efforts across countries, as such could lead to enhanced institutional capacity and sustainable investment-generation policy.

Originality/value

Since panel regression techniques used by the previous studies (Fixed and Random effects) could be susceptible to possible statistical errors due to endogeneity issue and might not be well suited for explaining long-run effect or capturing the part of investment sustainability, their conclusions could be misleading and remain untenable in West Africa' s context. Hence, the study adopts techniques (DOLS and FMOLS) which could account for endogeneity issue and provide better elucidations for long-term effects.

Abstract

Purpose

Several factors may play critical roles in alterations to product quality during storage of hog plum juice. This study aims to evaluate variations to physicochemical, antioxidant, anti-nutritional properties and microbial stability of hog plum juice during storage.

Design/methodology/approach

Juice was produced from hog plum fruits and stored for eight weeks at refrigerated and ambient conditions. Physicochemical, antioxidant properties, antinutritional factors and microbial properties of juices were determined using standard procedures

Findings

Degradation of ascorbic acid was higher in juices stored at ambient conditions (64.4%) compared to those stored by refrigeration (44.4%). Trends were similar for total phenolic, total flavonoid and total carotenoid contents. Total phenolic, total carotenoid and lycopene contents of fresh juice were 3.9 mg GAE/mL, 4.0 mg/mL and 1.3 mg/mL, which were not significantly different (at p = 0.08, 0.07 and 0.08, respectively) from the values at two weeks of storage at refrigerated conditions (3.9 mg GAE/mL, 3.9 mg/mL and 1.3 mg/mL). A sharp decrease of more than 40% (p = 0.02) in lycopene was recorded after four weeks, irrespective of storage temperature. Pasteurized hog plum juice showed no microbial growth until after four weeks of refrigerated storage when 1 CFU/mL each of bacterial and fungal growth were recorded. The juices, however, showed higher susceptibility to fungal growth as storage period increased.

Research limitations/implications

Other variables not considered in this study such as nature of packaging materials may have significantly contributed to the observed data set. Further studies may, therefore, widen the scope of discussion to evaluate the associated relationship of these variables. Hog plum juice retained a considerable amount of bioactive components during refrigerated storage, which makes it a viable nutraceutical drink with industrial potentials and possible positive health implications for consumers.

Practical implications

This study provides new information that support the possible classification and use of hog plum juice as a safe functional beverage for human consumption.

Originality/value

Although the effect of storage temperature was significant in most of the properties studied, storage duration seems to have a greater influence on the stability of quality parameters during the storage of hog plum juice.
