This research was designed to investigate the effect of period of fermentation on the microbial, mineral and proximate composition of fermented Parkia biglobosa seeds. The bacteriological, nutritional and sensory parameters were carried out on the raw, dehulled and fermented seeds. The result of the total bacterial counts showed that the raw seed had 3.67 log10cfu, there was a significant increase in the total bacteria count from 2.20 log10cfu/g in dehulled unfermented bean to 9.248 log10cfu/g at 96 h of fermentation. The bacteria isolated were Bacillus subtilis (32 isolates), Lactobacillus plantarum (9 isolates), and Leuconostoc spp (3 isolates). The pH increased significantly from 4.57 in the raw seeds to 8.40 at 96 h of fermentation. The titratable acidity decreased from 0.179N in the raw seeds until it got to 0.0313N at 96 h of fermentation. The proximate composition on dry mass basis showed that ‘iru’ fermented for 48 h had the highest protein content of 41.023%. The carbohydrate decreased from 42.153% in the raw seed to 20.733% at the end of fermentation. Four of the minerals; lead, cadmium, cobalt and nickel were detected in the raw seeds but were no longer available after dehulling. Phosphorus, sodium, calcium and potassium increased during the fermentation period. The sensory result showed that the intensity of growth on the surface of the fermenting bean increased. Moreover, the sensory score on the texture showed that the seed became softer as the fermentation progressed. The colour became darker and the ammonia odour became more pungent. The overall-liking showed a significant increase as the fermentation progressed where the panelist preferred the product fermented for 72 h. The result from this study revealed that the best time for fermentation of Parkia biglobosa seeds to produce good quality ‘iru’ was between 48 h and 72 h.","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121370276","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}

The fungal isolated were tested for its ability to cause the same disease condition in a healthy Citrus (C. limonum and C. aurantifolia).The extracts were concentrated at different range from 5-30 mg/ml. The study showed that the extracts of Aframomum melegueta were able to suppress fungi growth on Citrus aurantifolia and Citrus limonum. All the concentrations of the ethanolic extract of small A. melegueta were potent to all the organisms. The small seed ethanolic extracts were most effective on Rhizopus stolonifer while larege seed ethanolic extracts were most effective on Alternaria tenuis which recorded the highest zone of inhibition. I recommended that 5mg/ml concentration which has the highest zone of inhibition of the extract can be used as spray in controlling the postharvest deterioration of the citrus fruits. Therefore, they will serve as a good natural seed fungicide (protectant) against Citrus in storage.","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128008506","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}

Data were collected using well-structured questionnaire administered to 60 cassava processors. Data collected were analyzed using descriptive statistics, Profit function, independent sample t-test and Analysis of Variance (ANOVA). Results showed that majority of the processors were within the age group of 31–40 years with mean year of experience of 34 years. They were mostly women with an average of 8 persons per household. Traditional technologies mostly were employed by the cassava processors. The profitability analysis showed that cassava processing into garri (fried cassava granules), chips and fufu/akpu (cassava dough) are profitable, (t =23.55, 11.95, 12.37: P≤ 0.01). Moreover, the result of the ANOVA showed that there was a significant difference (F=44.48:P≤0.01) in the profit level of cassava processed into garri, chips and fufu/akpu. The result of the post-hoc of ANOVA shows that among the three cassava products studied, garri had the highest profit. The cassava processors encountered many set-backs like poor equipment, high cost of transportation, inadequate capital and poor road network even though processing is a viable and profitable venture. Modern processing technologies should be developed and disseminated to processors while adequate infrastructural facilities and credits should also be provided.","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124901015","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}

The specific objectives of the study were to identify the farmers’ adaptation methods, identify the determinants of choice of the adaptation methods, the limiting factors to farmers’ adaptation options in the study area. A total of 120 famers were selected using multistage random sampling technique. Data were collected using a structured questionnaire. The data were analyzed using descriptive statistics such as percentage responses and multi- nominal logit model and factor analysis. The adaptation strategies used by the goat farmers were use of use of nutrient-dense diets, drinking water, planting of tree as shade and location of house in the farm. Additionally, the effects of goat production to the environment were deforestation, land degradation, climate change, air pollution and rodent menace. In addition, goat Production technologies to curtail environmental pollution were precious feed management, litter management, use of hydrophilic products, use of rat poison and trap, adequate housing and proper manure disposal. The factors influencing farmers’ choice of adaptation methods were level of education, membership of cooperative, farming experience, poor access to extension services and access to credit. The determinant factors to the adoption of goat production related environmental technologies were level of education, extension visit, off farm income, farming experience and membership of organization.
