Lost in aggregation? On the importance of local food price data for food poverty estimates

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is
