| The gum tree (Acacia senegal) in the Sahel-Sudan zone has many environmental benign functions. An important function is to control desertification. In this paper we analyze farmers' economic incentives to preserve the existing gum trees and their incentives to create new plantations using a real options approach. Results indicate that agricultural crops provide higher economic benefits as compared to gum agroforestry system. However, on the one hand, as gum arabic is produced during the dry period and land is abundant, there are low incentives for deforestation. Instead, farmers' tend to leave the land idle and let the tree growing. On the other hand, our results suggest that an increase in the prices of gum arabic of about 330 per cent is needed to induce... |

| Microencapsulation technology is an alternative to stabilize stress factors and protect food ingredients or additives, which include environmentally sensitive bioactive principles in protective matrices to increase their functionality and life span. The objective of this research was to study conditions to obtain microcapsules with antioxidant capacity from a maqui (Aristotelia chilensis [Molina] Stuntz, Elaeocarpaceae) leaf extract by emulsification and subsequent retention after microencapsulation. Microcapsules were produced by water-in-oil emulsion (W/O) using a phase of the aqueous maqui leaf extract and gum arabic, and a liquid vaseline phase. Maqui leaf extract antioxidant capacity was 99.66% compared with the aqueous phase of the emulsion at 94.38... |

| In commercial corn production, small seed size is discarded from the seed lot and used as the animal feed, resulting in less profit to the seed industry. Therefore, the objective of this research was to increase seed size by seed pelleting methods. In this study, the types of filler pelleting materials and ratio of binder materials were investigated. The experiment was conducted at Seed Quality Test Laboratory of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Small seed size of hybrid corn that retained on grade 14/64” diameter sieve perforations were pelleted with seven different types and ratios of fillers (vermiculite, bentonite, pumice, calcium sulphate, calcium carbonate, charcoal and coconut) with four different types of binders... |
