Effect of preservation techniques on the phytochemical profile, antioxidant activity, and glucose adsorption capacity of oyster mushrooms (Pleurotus ostreatus)
No full textThe growing demand for foods with enhanced shelf life and nutritional value has driven the rapid expansion
of processed food products, often outpacing natural alternatives. This study explores the effects of oven-drying, salt-drying, and freeze-drying on Pleurotus ostreatus (Oyster mushrooms) cultivated on oil palm frond
substrates. Key parameters analysed include moisture content (MC) and protein content (PC), total phenolic
content (TPC), antioxidant activity, glucose adsorption capacity (GAC), and elemental composition. CHNS
analysis confirmed the presence of carbon, hydrogen, nitrogen, and sulphur in all substrates, while MC varied
slightly (82�88.54 %) with substrate composition. Protein analysis revealed that freeze-dried samples had
the highest PC, while SDS-PAGE profiling showed protein bands (35�75 kDa) in all samples except salttreated ones, which were denatured. Over 60 days, oven-dried substrates maintained relatively high PC
(»4�5 mg/ml), whereas freeze-dried samples exhibited a significant decline. Salt-treated and oven-dried
samples extracted with phosphate buffer consistently showed low PC. GAC increased with molar concentration, with oven-dried samples exhibiting the highest efficiency. Regarding antioxidant properties, salttreated samples demonstrated increased free-radical scavenging activity after storage, while oven-dried and
freeze-dried samples showed a decline. TPC decreased over time in all treatments, but oven-dried samples
gradually increased, particularly in substrate III (87.5 %). These findings suggest that preservation methods
effectively extend shelf life while maintaining bioactive compounds that may influence glucose absorption
and the potential anti-diabetic properties of P. ostreatus. Further research should explore sensory attributes,
toxicological safety, and in vivo molecular mechanism

No full textA Probit Regression Analysis of Sustainable Disaster Preparedness in Erosion-Prone Areas of Abia State, Nigeria
No full textThe study assessed the determinants of disaster
preparedness in erosion-prone communities of Abia State, Nigeria, by employing the probit regression analysis. A sample size of seventytwo (72) respondents was selected using the two-stage sampling technique. Using the probit regression analysis, the relationship between the farmers’ perception of erosion causes and disaster preparedness was analyzed. A perception score was created and categorized into binary preparedness (1 = Prepared, 0 = Not Prepared) based on the mean (3). The independent variables included
in the model were human activities, climate change, soil nature, and religion. The marginal effect was not included in this study. The results showed that farmers’ perception of gully erosion causes, particularly climate change, soil nature and religion, were statistically significant at a 1% level of significance, while human activity was found significant at a 5% level of significance, and they are negatively associated with disaster preparedness. Therefore,
policymakers and development professionals should bridge these knowledge gaps by promoting science-driven understanding through education, extension services and effective communication methods. Also, local beliefs through a participatory approach should be incorporated without perpetuating a culture of inaction.

No full textDeterminants of Environmental Behaviour Among Small and Medium Enterprises in Lagos, Nigeria
No full textThis study examined the environmental behaviour of
small and medium-sized enterprises in Lagos, Nigeria, to ascertain
their disposition and factors that shape Small and Medium
Enterprises (SMEs) behaviour toward their immediate environment.
Given that SMEs in Nigeria are poorly regulated, most enterprises
have failed to adhere to international best practices in their
operations. Thus, this study assessed the determinants of SMEs'
environmental behaviour within Lagos State, chosen for its status as
Nigeria’s commercial nerve centre and its concentration of over
11,500 SMEs. A combination of quota, purposive, and convenience
sampling techniques was employed to select the sample of SMEs that
participated in the study. Questionnaires were administered to 700
SMEs, however, only 521 were properly completed and returned by
SMEs. Data were analyzed using multiple regression techniques.
The coefficients of determination (R2) indicated that 48.4%, 27.9%,
63.6%, and 40.5% variations in environmental behaviour among
micro, small, medium SMEs and for all enterprises combined are
explained by the independent variables. Results revealed a
significant relationship between SMEs’ years of existence and their
environmental behaviour. Across all SME categories, habit has an
inverse relationship with environmental behaviour; conversely,
belief, personal responsibility, individual, and Institutional factors
all have a positive relationship with environmental behaviour. The
study concludes that a decrease in anti-environmental habits among
SMEs will enhance pro-environmental behavior, contributing to
more sustainable business practices, and recommends improvement
in the habits and environmental behaviour of medium enterprises in
Lagos
