The study evaluated the quality of gluten–free biscuits made from maize and soybean flour blends, and compared them with 100% wheat flour biscuit. Flours were prepared from maize and soybean grains. The soybean flour was used to substitute 5, 10, 15, 20 and 30% of maize flour in order to obtain various flour blends. The chemical composition, functional and pasting properties of the flours and their blends were determined. The flour blends were used to prepare biscuits, which were analyzed for the chemical composition, physical and sensory properties. The results showed that the moisture, protein, fat, fiber, ash, and carbohydrate contents of the flours ranged from 10.58-11.37, 7.30-42.23, 1.82-10.15, 0.34-5.20, 0.85-4.00, 27.84-76.41%, respectively. The phosphorus, iron and magnesium contents varied from 1.24-166.96, 2.31-19.54, 0.01-157.56mg/100g, respectively. The bulk density, foaming capacity, water absorption and oil absorption capacity of the flours and the blends ranged from 0.66-0.68g/cm3, 3.22-29.25%, 85.00-210.00g/g and 80.0-145g/g, respectively. The peak viscosity, trough viscosity, breakdown viscosity, final viscosity, setback viscosity, peak time and pasting temperature decreased with an increase in the level of soybean flour incorporation and ranged from 113.05-127.98, 83.95.97.05, 23.99-41.95, 224.02-409.98, 136.01-325.03, 6.12-7.05, and 55.4-95.0 RVU, respectively. The moisture, protein, fat, fiber, ash, and carbohydrate of the biscuits increased from 4.10-9.19, 34.94-40.38, 27.24-31.39, 6.88-7.93, 0.53-3.79, and 16.99-23.44%, respectively. The phosphorus, iron, and magnesium contents of the biscuits ranged from 47.01-65.91, 3.37-7.08, 0.0018-0.0047mg/100g, respectively. The sensory scores for the biscuit samples decreased with the level of soybean flour. However, the biscuits containing 10% soybean flour was not significantly (p>0.05) different from the 100% wheat flour biscuits in all the sensory attributes evaluated. Therefore, comparable biscuits with 100% wheat biscuit could be produced from the blend of 90 % maize flour and 10% soybean flour.

To consume or not to consume farmed fish diagnosed with nutritional disorders within an aquaculture culture system is a question that resonates with fisheries and aquaculture experts worldwide. Proper fish health management in aquaculture should be a critical area of concern for all fish farmers. It has become a fundamental requirement for achieving sustainable aquaculture production. However, many fish farmers, particularly in developing countries lack knowledge about nutritional fish diseases and how to effectively manage them on the farm. Like human health, farmed fish’s health in aquaculture systems should be a daily priority for fish farmers. Nutritional fish diseases are often overlooked by the majority of fish farmers, even at the commercial level. Most Fish farmers may not realize that nutritional disease prevention can be achieved through the use of well-formulated fish feeds that meet all the nutritional requirements for fish growth. Additionally, maintaining good water quality and implementing best management practices are essential to ensure that the fish stock remains healthy in the culture system. Since different fish species have varying nutritional dietary requirements, it is important to formulate the right nutritional diet based on the specific fish species being cultured. Fish feeds should contain the necessary nutrients to ensure opportunistic disease resistance. Furthermore, fish farmers should be familiar with early diagnosis techniques for nutritional fish disease disorders. This ensures that the harvested fish reaching the market does not raise concerns about the quality and safety of farmed fish products. Failure to diagnose nutritional disorders associated with poor feeds and diets can create doubts in the rapidly growing aquaculture industry. Therefore, this review aims to explore the nutritional requirements of farmed fish species, the impact of nutritional deficiencies on human and public health, the causes of nutritional disorders, and viable therapies for managing these diseases in farmed fish. The data for this review article were collected from various secondary sources, including internationally reputable peer-reviewed articles, conference proceedings reports, internet searches, and more. The findings highlight the importance of providing aquaculture farmers with essential information on fish nutrition-related disease control, as nutritional diseases have been found to be detrimental to fish health and public health. Moreover, many farmed fish affected by nutritional disorders have entered the global fish market, raising questions about their impact on human health. Therefore, it is crucial for fish farmers to prioritize early diagnosis of nutritional fish diseases to ensure the safety of farmed fish in the market and maintain consumer confidence in farmed fish globally. The study recommends further research into the potentially lethal effects of different nutritional fish diseases, particularly when consumed in

Cowpea leaves are lost annually due to infestation and spoilage when being transported to clients and the losses at the local markets are brought on by inadequate postharvest handling procedures and market glut, particularly during peak seasons. High moisture content from the cowpea leaves at harvest stage may contribute to increased spoilage hence lowering quantity and quality. The choice of appropriate harvesting stage and drying method can help to reduce this problem. The aim of this study was to determine the best harvesting stage and efficient drying method that would maintain high leaf nutrient composition. Cowpeas variety M66 was used for the research and the treatments included three harvesting stages (21, 35 and 49 days after sowing [DAS]), three drying methods (open sun, solar dryer and oven. Data was collected on iron, calcium, crude fibre, beta carotene, protein and moisture content. The data was subjected for variance using Statistical Analysis System 9.2 edition and significantly different means separated using least significant difference at 5%. The results indicated significant (p<0.05) differences in moisture, calcium, proteins, beta carotene and crude fibre content in both trials. Harvest stage and drying method did not significantly (p<0.05) influence the iron content. Oven and solar drying methods showed better nutrient and mineral retention in the three harvesting stages when compared to the open sun drying method.

This paper describes the principles and practices of effective food safety risk communication developed under the “Asia-Pacific Economic Cooperation Food Safety Risk Communication Framework and Associated Guidelines”. The framework recommends that effective food safety risk communication needs to be centered on the clear goal of protecting consumer health by ensuring transparency and timeliness, and communication on food safety matters should be conducted in a two-way process. It emphasizes the need to provide the public with credible information based on science and evidence and highlights that food safety is a shared responsibility among all stakeholders, including industry, government agencies, media organizations and consumers. It further highlights that food safety risk communication needs to be conducted in a consistent, systematic, inclusive, consultative, and preventative manner. The framework also indicates that effective food safety risk communication needs to pay attention to the backgrounds, experiences, and needs of concerned audiences. It stresses the importance of continuous improvement of the communication system to ensure food safety risk communication to be effective. Focusing on effective communications in response to food safety incidents, emergency or crisis situations, as well as everyday food safety communications, these principles and practical guidelines will help food safety regulators, food industry, food safety educators and other stakeholders improve their communications with target audiences.

Introduction: The nutritional status and adequacy of nutrients in the food consumed by commercial drivers have significant implications for their overall health, well-being, and job performance. Aims: The study assessed the nutritional status and nutrient adequacy of food consumed by commercial drivers in Abeokuta South Local Government area, Ogun State. Study Design: A descriptive cross-sectional design was used to carry out this study. Place and Duration of Study: The study was carried out in the Major Parks of Abeokuta South Local Government from November 2019 to February 2020. Methodology: The data was obtained from randomly selected three hundred (300) commercial drivers in the major parks (Asero, Ijaiye, Kuti, and Sapon) of Abeokuta South Local Government. A structured-interviewer-administered questionnaire was used to obtain data on the respondent’s demographics and socioeconomic characteristics, anthropometrics characteristics were assessed using a standardized method by trained anthropometrists, and the dietary intake of the respondents was obtained using a validated 24-hour recall questionnaire. Data were analyzed and presented using descriptive and inferential statistics. Results: All (100%) of the respondents were males with a mean age of 38.7±0.49 years. The mean height and weight of the respondents were found to be 1.68±0.86 m and 68.50±8.47 kg respectively. More than half (59.7%) of the respondents had a normal BMI, 34.3% and 0.3% were overweight and obese respectively and only a few (5.7%) were underweight. The nutrient adequacy results revealed inadequacies of Vitamin C (83.3%), Vitamin B1 (66.7%), Vitamin B6 (79.3%), Calcium (89.3%), Zinc (53.3%), and Magnesium (70.7%). Conclusion: It is concluded that overweight, obesity, and micronutrients inadequacy is prevalent among commercial drivers. Malnutrition and micronutrient inadequacy among commercial drivers should be recognized as a public health problem and strategies to improve their status and nutrient intake should be implemented.

This study investigated the propensity to pay for modern apparatus processing locust beans in Ekiti State, Nigeria. Utilizing primary data and a multistage sampling strategy, 240 processors were chosen for the study. The collected data were analyzed utilizing descriptive statistics and an inferential statistical instrument, such as Logit and ordinary least square regression analysis. About 72 percent of processors were married and had an average of eight years of experience processing locust legumes. The majority of respondents belonged to a cooperative group (66.7%) and had no access to credit (100%). The average monthly income from processing was N18,000. The majority of respondents (65%) were unwilling to pay for the service of centralized, advanced or contemporary processing equipment. According to the results of the Logit regression analysis, the variables that significantly influence willingness to pay for the service of centralized modern locust bean processing equipment were household income and processing experience (1%), level of education and age (5%), and household size (10%). The Ordinary Least Square (OLS) analysis reveals that household size and education level were significant at the 1% level, while age and marital status were significant at the 5% level and processing experience was significant at the 1% level. The study suggests that processors ready to pay should form a formidable cooperative to secure grants or loans to establish a centralized, contemporary locust processing cottage. The government should educate processors on modern food processing and safety at all levels.

Aim: Malnutrition remains a public health problem in children aged under five years in Burkina Faso. Research to find indigenous vegetables with high content of minerals can contribute to fight against children malnutrition. The aim of this study was to assess minerals composition of Solanum aethiopicum L. and Amaranthus hybridus L. leaves grown in Burkina Faso. Methodes: The leaves have been collected in three markets of Ouagadougou. For the two plants, the dry leaves have been analysed for the following minerals content: Potassium (K), Calcium (Ca), Magnesium (Mg), Sodium (Na), Phosphor (P), Iron (Fe) and Zinc (Zn). The analyses have been done using the atomic absorption spectrophotometer and flame photometer methodes. Results: The results showed high mean concentration in K, Ca and Mg in the leaves of the two plants. For Solanum aethiopicum leaves, the concentration in K, Ca and Mg was respectively 3064; 1048 and 666 mg/100 g. The trace elements content were also high: Fe (12 mg/100 g) and Zn (20 mg/100 g). For Amaranthus hybridus leaves, the concentration in K, Ca and Mg was respectively 3573; 606 and 475 mg/100 g. The leaves of Solanum aethiopicum had the highest content of following minerals: Ca, Mg, Na, P, Fe and Zn compared to Amaranthus hybridus leaves. Conclusion: This study showed that both plants are good sources of important minerals. They are essential to be included in the diet of children to promote growth and contribute to fight against malnutrition.

For the two plants, the dry leaves have been analysed for the following minerals content: Potassium (K), Calcium (Ca), Magnesium (Mg), Sodium (Na), Phosphor (P), Iron (Fe) and Zinc (Zn). The analyses have been done using the atomic absorption spectrophotometer and flame photometer methodes. \u0000Results: The results showed high mean concentration in K, Ca and Mg in the leaves of the two plants. For Solanum aethiopicum leaves, the concentration in K, Ca and Mg was respectively 3064; 1048 and 666 mg/100 g. The trace elements content were also high: Fe (12 mg/100 g) and Zn (20 mg/100 g). For Amaranthus hybridus leaves, the concentration in K, Ca and Mg was respectively 3573; 606 and 475 mg/100 g. The leaves of Solanum aethiopicum had the highest content of following minerals: Ca, Mg, Na, P, Fe and Zn compared to Amaranthus hybridus leaves. \u0000Conclusion: This study showed that both plants are good sources of important minerals. They are essential to be included in the diet of children to promote growth and contribute to fight against malnutrition.","PeriodicalId":11922,"journal":{"name":"European Journal of Nutrition & Food Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78244889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Aims: Ready-to-eat [RTE] animal products like ponmo are preferred by consumers due to its palatability and quality. However, foodborne pathogens particularly Staphylococcus aureus are sources of concern due to cross-contamination of raw and cooked cowhide. This study aimed to investigate the incidence of enterotoxigenic S. aureus in ready-to-eat locally processed cowhide. Methodology: Sixty (60) RTE cowhide samples were collected from different locations in Lagos, Nigeria and analyzed using conventional microbiological and molecular techniques for the detection of toxigenic S. aureus contamination. Suspected S. aureus isolates were confirmed by the presence of thermostable endonuclease [nuc] gene in their genome. Results: Result showed that 25 (41.67%) and 20 (33.50%) samples harbored coagulase-positive S. aureus and 20 other bacterial species different from S. aureus, respectively while 15 (24.83%) of the tested ponmo samples yielded no bacterial growth. Thirteen of the 15 randomly selected from the 25 suspected isolates were confirmed as S. aureus by the presence of thermostable endonuclease [nuc] gene in their genome. Enterotoxigenic genes were confirmed in all the 13 PCR detected S. aureus. Enterotoxin B gene is most prevalent in ponmo. Multiplex PCR detection of S. aureus enterotoxins [SE] genes revealed the molecular detection of different isolates carrying staphylococcal enterotoxin types A and B, mixed strain carrying both staphylococcal enterotoxins type A and type D. Antibiotic susceptibility of 20 S. aureus isolates revealed varying degrees of susceptibility patterns against the antimicrobial agents. Generally, gentamicin 70% (14/20), azithromycin 75% (15/20), co-trimoxazole 85% (17/20), levofloxacin 95% (19/20) were the most effective antibiotics to S. aureus. A low, ≥50% susceptibility was recorded to chloramphenicol 55% (11/20) and nitrofurantoin 65% (13/20). A higher resistance to streptomycin (90%; 18/20) and ceftazidime (95%; 19/20) was identified, with resistance to ceftazidime being the highest (95%; 19/20). Conclusion: It can be concluded that RTE ponmo vended in the study sites is of low hygienic quality and may be of health risk to consumers. High level hygiene practice and good manufacturing practices are required during the production, distribution and marketing of ponmo to curb the potential health consequences of eating ponmo.

Aim: Cookies from rice, banana and cashew-nut flour blends were prepared as alternative to gluten-free baby-led food for children. Place and Duration of Study: The study was carried out in the Chemistry Laboratory, Department of Science Laboratory Technology, University of Medical Sciences, Ondo, Nigeria and Food Processing Laboratory, Department of Food Technology, Auchi Polytechnic, Auchi, Nigeria between August, 2022 and January, 2023. Methodology: Baby-led weaning cookies were formulated from flour blends as 100% raw rice (RRC), 50% rice and 50% wheat (RWC) and 40% rice, 20% cashew and 40% unripe banana (RCB) and their physical properties, sensory attributes, proximate properties, mineral compositions, vitamin profiles and anti-nutrients were determined and compared with 100% commercial cookie (CMC) with the view to substituting wheat flour with suitable flour blends with enhanced nutritional quality. Results: The peak diameter (10.40±0.20 mm), thickness (6.37±0.06 mm) and weight (17.65±0.04 g) were obtained in RCB. Spread ratio was highest (2.66±0.11) and lowest (1.42±0.01) in CMC and RWC respectively while spread factor decreased from 100% in CMC to 77.19% (RRC), 53.46% (RWC) and 62.47% (RWC). The grittiness, texture, aroma, taste and general acceptability of RCB were significantly similar to those of CMC (P < 0.05). Na, K, Mg and Zn contents increased in RCB. Proximate compositions (%) of the cookies formulated varied significantly from CMC. Peak crude protein (14.49±0.59), crude fibre (4.03±0.02) and fat (32.22±0.00) in RCB, ash (3.28±0.02) and carbohydrate by difference (58.15±0.13) in CMC and moisture (18.19±0.11) in RRC. The peak values of fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (B1, B2, B3, B6, B9, B12, C) were most abundant in RCB. The proportions (mg/g) of phytate, oxalate, tannins and phenols in the cookies formulated were comparatively lower than the lethal dose, implying that the cookies would be safe for consumption. Conclusion: RCB cookie had excellent nutritional quality, which, as a novel baby-led weaning cookie, could serve as a suitable alternative to commercial cookies.

Aim: To study the production of Nutrient – Dense Composite Flour from the blends of whole wheat flour, soybean flour (full fat) and oyster meat powder. Study Design: The study was design using the D-optimal combination design of Response Surface Methodology (RSM). Place and Duration of Study: The study was carried out at Department of Food, Nutrition and Home Science, University of Port Harcourt (Processing of raw materials) and the Department of Food Technology, Federal Institute of industrial research Oshodi, Lagos (Analysis of raw materials) between October 2021 and August 2022. Methodology: The raw materials were each processed to have wholesome flours, and then they were combined according to the matrix generated, which had ranges of 70 – 100%, 0 – 22%, and 0 – 8% for whole wheat flour (WWF), soybean flour (SBF) and oyster meat powder (OMP) respectively. Results: The design was used to assess the significance (5% probability) of the moisture, fat, and protein content, which ranged from 8.09 to 11.37%, 1.80 to 8.52% and 9.70 to 19.07% respectively; the water absorption (72.00 - 79.10BU), dough stability (9.3 - 17.5BU) and mixing tolerance index (25 - 50BU); and lightness and yellowness, which ranged from 65.48 - 83.2 and 13.77 - 23.58 respectively, of the flour blends. Protein content, water absorption dough stability, and mixing tolerance index were prioritized while moisture content, fat content, and yellowness were minimized for the numerical optimization of the responses. This study highlights the possibilities of utilizing non-conventional raw materials in the production of composite flour with balance nutritional and baking qualities. Conclusion: The best flour combination was 72.51% whole wheat flour, 19.63% soybean flour, and 7.86% oyster meat powder.
