“…However, these values were lower than values recorded for PF Benin (8.39 ± 0.32 c ) which were statistically similar to PP Benin (8.24 ± 0.15 c ), PP Elele (8.24 ± 0.60 c ), ASPI Oluku (8.34 ± 0.01 c ) and CHI Usen (8.32 ± 0.21 c ). The low moisture content of the wastes suggest that microbial growth will be slow 25 thereby reducing spoilage time for the waste compared to the plantain flesh.…”

Background: Global food insecurity is worsening as a result of the speedily expanding human population and this is taking a huge toll on the availability of feed for livestock. Alternative food sources are urgently required as livestock feeds to reduce the stern food competition between man and livestock. Agricultural waste may be able to provide cost-effective sources of nutrients. Aim: The study determines the proximate properties of agricultural waste for their possible use as raw material for animal feed. Material and methods: Consequently, 10 samples of agricultural waste were collected from locations in Edo state where the plants are cultivated in commercial quantities. Proximate analysis was performed on the samples using standard protocols to evaluate their nutritive potentials for utilization as feedstuffs for livestock feeds. The proximate properties of the agricultural waste were compared with plantain flesh (PF Auchi and PF Benin). Results: Significant variations exist among the samples (p < 0.05) with respect to their fat, protein, nitrogen free extract (NFE) and dietary fiber content. The following samples had highest proximate values; corn cob (moisture content at 17.38%), PP Usen (ash content at 7.58%), PP Benin (fat content at 7.20%), CHI Usen (fiber content at 12.70%), PP Auchi (protein content at 19.83%) and PF Benin (Nitrogen Free Extract (NFE) at 73.43%). Plantain peels had the closest proximate properties to plantain flesh. Conclusion: The results from the analysis show that the proximate properties of the wastes compare favorably with plantain flesh and will be suitable for livestock feeds production. The production of livestock feed from agricultural waste would also serve as an effective and attractive method to manage the waste. Keywords: livestock, agricultural waste, nutrient, feeds.

“…The parameters studied are moisture content, density, fracture modulus, and internal adhesion strength. Moisture content and density testing according to British Standard number 373 1957 [10]. Internal adhesion and fracture modulus tests were performed according to ASTM D-905-49 standards of 1981 [6][11] [12].…”

“…The average value of the list profile moisture content was 15.90 -18.85%, the lowest value was produced by the list profile with the type of plaster adhesive of 15.90% and the amount of adhesive 780 g of 18.79% (Table 1). It is suspected that the initial water content of coconut fiber is quite high reaching 19%, besides that it is also influenced by the ability of the material to absorb water so that it is easily affected by environmental factors [9][16] [17].Tukey's test results showed that the type of plaster adhesive produced a lower moisture profile and was significantly different from other types of adhesives, while the amount of adhesive did not differ markedly in all treatments (Figure 1) [10] [18].…”

List profile is a mineral board product that is increasingly in demand by the wider public. One of the advantages of list profiles is that they are cheap, quick to obtain, resistant to attacks by wood-destroying organisms, and can be obtained in the form of attractive ornaments. From an economic perspective, list profile with rofing filler is more expensive. Coconut fiber can be used as a type of filler that has the same strength at a low price. This research aims to determine the type and level of gypsum adhesive, white cement, and their mixtures on the properties of the coconut fiber list profile. The research design used a completely randomized design with Tukey’s follow-up test. The factors used were the type of adhesive (gypsum, white cement, and a mixture of gypsum with white cement), and the amount of adhesive (600 g, 690 g, and 780 g). The parameters observed were water content, density, thickness expansion, and fracture toughness. The research results showed that the type of adhesive had a significant effect on water content and thickness development, the amount of adhesive had a significant effect on density and the adhesive type had a significant effect on water content, while the amount of adhesive had a significant effect on density and thickness development. The average value of water content is 15.90 - 18.85 %, density 0.67 - 0.92 g/cm3, thickness expansion 0.37 - 2.54 % and strength at fracture 3.88 - 35.90 kg/cm2.

“…In the narrow sense, food safety can be defined as the opposite of food risk, i.e., as the probability of not contracting a disease as a consequence of consuming certain food. Safety value for consumers is divided into three sources of health risk: microbiological (presence of pathogen microorganism) [33][34][35], chemical (naturally occurring in plants, nutrients, contaminants present in the environment as residues of harmful substances, additives allowed in food but exceeding certain concentration limit, residues of pesticides, herbicides, traces of chemicals migrating from packaging, residues of drugs, antibiotics and medicines, residues of detergents and disinfection agents, etc.) and physical (as appearance of external and internal materials of various origin, e.g., splinter, file dust, stones, straw).…”

Temperature fluctuation and abuse in the food cold chain (FCC) is becoming an increasingly crucial factor in the process of food production and for the logistic business, especially in COVID-19 pandemic. The quality of perishable food products depends largely on accurate transport and maintenance temperature. The evidence for temperature-related food waste and loss is extensive. The research problem is thus: how to decrease and control food losses caused by temperature abuse in the FCC and restrictions due to the COVID-19 pandemic. The primary objective is to propose a framework for real-time temperature measurement protocols supported by passive RFID, IoT and Statistical Process Control (SPC) charts. This method allows not only the signaling of temperature abuse alerts but, in addition to hitherto methods, investigation and mitigation of the causes of process instability of individual FCC links in the future. The secondary objective is to delineate the necessary data sources and ways of their collection and utilization in order to decrease food losses and waste via process stabilization of temperature in transport and storage. As contribution to current literature and practice, we offer an in-depth analysis of threats in the FCC in food transport and storage infrastructure and a solution supplemented by SPC charts and tested in controlled experiments that is practicable from economic and technical standpoints.
