Microencapsulation is a good alternative to transform liquid food flavourings, such as coffee oil, into stable and free-flowing powders. Thus the aim of this study was to evaluate the influence of process conditions on the microencapsulation of coffee oil by spray drying, using gum Arabic as encapsulating agent. The effect of total solid content (10?30%), oil concentration with respect to total solids (10?30%) and inlet air temperature (150?190 °C) on the encapsulation efficiency, oil retention, moisture content and powder hygroscopicity were evaluated by a complete 23 central composite rotatable design. Both encapsulation efficiency and oil retention were negatively influenced by oil concentration and inlet air temperature, and positively affected by total solid content, which could be related to the emulsion viscosity and droplet size. Particles produced at the optimized process conditions (30% of total solids, 15% of oil with respect to total solids and inlet air temperature of 170 °C) were evaluated for oxidative stability and showed to be stable during storage at 25 °C, but not at 60 °C. At this temperature, pure oil presented higher lipid oxidation than encapsulated, confirming the protective effect of microencapsulation on the oxidative stability of this product. |

Root damage caused by aluminum (Al) toxicity is a major cause of grain yield reduction on acid soils, which are prevalent in tropical and subtropical regions of the world where food security is most tenuous. In sorghum, Al tolerance is conferred by SbMATE, an Al-activated root citrate efflux transporter that underlies the major Al tolerance locus, AltSB, on sorghum chromosome 3. We used association mapping to gain insights into the origin and evolution of Al tolerance in sorghum and to detect functional variants amenable to allele mining applications. Linkage disequilibrium across the AltSB locus decreased much faster than in previous reports in sorghum, and reached basal levels at approximately 1000 bp. Accordingly, intralocus recombination events were found to be extensive. SNPs and indels highly associated with Al tolerance showed a narrow frequency range, between 0.06 and 0.1, suggesting a rather recent origin of Al tolerance mutations within AltSB.A haplotype network analysis suggested a single geographic and racial origin of causative mutations in primordial guinea domesticates in West Africa. Al tolerance assessment in accessions harboring recombinant haplotypes suggests that causative polymorphisms are localized to a, 6 kb region including intronic polymorphisms and a transposon (MITE) insertion, whose size variation has been shown to be positively correlated with Al tolerance. The SNP with the strongest association signal, located in the second SbMATE intron, recovers 9 of the 14 highly Al tolerant accessions and 80% of all the Al tolerant and intermediately tolerant accessions in the association panel. Our results also demonstrate the pivotal importance of knowledge on the origin and evolution of Al tolerance mutations in molecular breeding applications. Allele mining strategies based on associated loci are expected to lead to the efficient identification, in diverse sorghum germplasm, of Al tolerant accessions able maintain grain yields under Al toxicity.
