food packaging is inseparable step of the process, storage, distribution and marketing of the product. proper packaging increases the shelf life of food; for this reason that is one of the main characteristics in the food industry. one of the new concepts in food packaging is bio packaging, that is developed to respond to the needs of consumers and food products with higher durability. using ed...
Many cultivated and natural fruits play an important role both in food security and in meeting nutritional requirements in households throughout PNG. Fruit fly species of the family Tephritidae account for significant preharvest and postharvest food losses, and a reduction of these losses will improve food availability at household levels. The Papua New Guinea Fruit Fly Project (PNGFFP) has con...
Food losses in field and store 5 cause outstanding losses in many crops. Because there are few trained nematologists, many other important nematode problems on key food crops such as rice and paddy remain uninvestigated. Because nematodes are soil organisms, control is especially difficult. Few satisfactory nematicides are known and these are too expensive for most agricultural crops in Europe....
Post-harvest losses represent a significant threat to food security and farmer incomes worldwide. It is an inefficiency in the global food production system that is avoidable. In deducing principles of designing and implementing agricultural extension programs to reduce post-harvest losses, valuable lessons can be gleaned from the handful of previous extension projects and programs addressing p...
Food losses can occur during production, postharvest, and processing stages in the supply chain. With the onset of worldwide food shortages, interest in reducing postharvest losses in cassava has been increasing. In this research, the main goal was to evaluate biochemical changes and identify the metabolites involved in the deterioration of cassava roots. We found that high levels of ascorbic a...
Radiations and radioisotopes are used in agricultural research to induce genetic variability in crop plants to develop improved varieties, to manage insect pests, monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. Use of radiation and radioisotopes in agriculture is one of the most important fi...
The aim of this study was to determine the effect of addition of green coffee extract (GCE) in concentrations from 0.25 to 1 g 100 g-1 on the physical, sensory and chemical properties, and antioxidant activity of some food products. Two kinds of gnocchi (from fresh and dried potatoes), sponge cake, bread, mayonnaise, marshmallows, caramel candies and jellies were prepared. Among supplemented pr...
The assessment of crop yield losses is needed for the improvement of production systems that contribute to the incomes of rural families and food security worldwide. However, efforts to quantify yield losses and identify their causes are still limited, especially for perennial crops. Our objectives were to quantify primary yield losses (incurred in the current year of production) and secondary ...
