Abstract Quantitative characterization of nucleic acids is becoming a frequently used method in routine analysis of biological samples, one use being the detection of genetically modified organisms (GMOs). Measurement uncertainty is an important factor to be considered in these analyses, especially where precise thresholds are set in regulations. Intermediate precision, defined as a measure between repeatability and reproducibility, is a parameter describing the real situation in laboratories dealing with quantitative aspects of molecular biology methods. In this paper, we describe the top-down approach to calculating measurement uncertainty, using intermediate precision, in routine GMO testing of food and feed samples. We illustrate its practicability in defining compliance of results with regulations. The method described is also applicable to other molecular methods for a variety of laboratory diagnostics where quantitative characterization of nucleic acids is needed.

Winter Squash

Winter squash cv 'Cehualca' (Cucurbita moschata Duchense) is a seasonal crop that has been used as food and animal feed. The objective of the present study was to characterize physical, chemical and physicochemical properties of the winter squash cv 'Cehualca'. Morphological, chemical and physicochemical analyses were performed, including fiber, carotenoids, phenolic and mineral contents in the winter squash. The morphological analysis showed that the squash 'Cehualca' did not have a homogeneous morphology. Data about their physical and physicochemical characteristics showed large variability. Also, high content of carotenoids and dietary fiber was observed in squash. The oil and total phenolic content was low in comparison with other fruits. The mineral content exceeded the values recommended to meet the nutritional needs of consumers, except for sodium (both in pulp and shell), potassium and magnesium in the shell.

Summary The chemical characterization of the pulp, peel and seeds of cocona (Solanum sessiliflorum Dunal) was determined. In artisanal fruit processing, 26.3% of peel and 9.7% of seeds were obtained. The seeds showed a high potential for the development of value-added products because of their dry matter contents (23.46%) as follows: carbohydrate (69.37% dry basis (d.b.)), nitrogen (3.18 g/100 g of seed d.b.), K (0.023 g/100 g of seed d.b.), Fe (0.0185 g/100 g of seed d.b.) and dietary fiber (21.27 g/100 g of seed d.b.). The carbohydrate, dietary fibre and mineral contents of the pulp, peel and seeds also highlighted the agroindustrial potential of the fruit in that these constituents could be used to develop functional foods, food additives, preparations for functional diets and dietary supplements.

Aim: To ascertain scientifically by proximate analysis, the nutrient composition and mineral contents of the American cockroach Periplaneta americana. Study Design: Completely randomized sample design (CRD) was engaged in the study with 15 parameters replicated five (5) times, totaling seventy five experimental samples. The whole experiments were repeated in three trials. Place and Duration of Study: Postgraduate laboratory, Faculty of Science, Niger Delta University Wilberforce Island, Bayelsa State, Nigeria between September 2019 and February 2020. Methodology: The nutrient composition and mineral profile of the cockroaches were ascertained using randomly selected cockroach sample while adopting standard procedures of AOAC, (1990, 2005).Statistical analysis and significant difference tested at alpha level p≤ 0.05 was done using Turkey HSD test for difference between mean while results were presented in tables. The software used was SPSS version 20. Results: The results for proximate analysis of nutrients found in P. americana are given as follows: moisture content: 12.42±1.6%, Crude ash: 3.52±0.8%, crude protein: 8.72±1.3%, crude fat: 17.64±1.9%, fibre: 21.28±2.1%, Carbohydrate (dry method): 87.56±4.2% and Carbohydrate (free nitrogen extract): 48.76±3.1%. Furthermore, P. americana was proven rich in both micro and macro minerals in very high to low concentrations such as:calcium (468.00±9.7mg/100g), magnesium (362.00±8.5mg/100g), iron (274.60±7.4mg/100g), potassium (242.5±7.0 mg/100g), phosphorus (128.76±5.1mg/100g), sodium (110.68±4.7mg/100g), manganese (12.63±1.6mg/ 100g), copper (7.54±1.2mg/100g) and zinc (4.74±1.0mg/100g). All results were calculated as mean percentages of five experimental evaluations. Conclusion: Cockroaches are omnivores and feed on rotten vegetables, waste products from industries such as brewer’s yeast, leftover bread, brewer’s spent grains and several other food materials, hence they are very well efficient at turning plant based feed into animal protein. This makes them efficient projectors for addressing the problem of shortage of animal proteins thereby fulfilling the food security goal of sustainable development.

Abstract In this research the mineral elements and the oil and protein contents of thirteen sunflower hybrids grown in Brazil, were studied. In addition, the possibility of jointly obtaining products with high productivity and high oil and protein contents was evaluated. The research showed high achene productivity, exceeding the national average, mainly by the hybrids BRS G44, SYN 045 and M 734. It should be taken into account that some hybrids, such as NTC 90, despite their high productivity, are not suitable for production when the purpose is to obtain oil and protein meal. The hybrid BRS G46 presented high oil and protein contents. On the other hand, SYN 065 was the least productive (808.10 kg ha-1) and, despite the fact that this hybrid showed an above average oil content, it showed the lowest protein content of the grains analysed. In general, the samples analysed had higher concentrations of K, Mg, S, Fe, Zn, Mn, Cr, Ni and Cu, whereas the mineral contents of Mo, Co and Se were present at lower levels. The hybrid BRS G45 indicated the presence of larger amounts of elements at higher concentrations, such as: Mg, S, Cr, Fe, Ni, Cu and Zn, followed by BRS G44, which showed higher contents of Mg, Cr, Mn, Fe and Ni. The characterization of the Brazilian hybrids in this study allowed for their differentiation for specific purposes and the possibility of oil production combinations, producing oils with characteristics that make them apt for alternative uses of their by-products (such as the hybrid BRS G46), this being a great opportunity to increase the farm income.
