Este trabalho teve como objetivo avaliar as características físico-químicas do óleo de bacaba durante o armazenamento. Após o processo de extração mecânica do óleo, este foi armazenado em vidro âmbar em temperatura ambiente média de 26 ºC, por 12 meses. A cada 3 meses foram avaliadas as variáveis índice de refração, ácidos graxos livres, índice de acidez e índice de peróxido. O delineamento estatístico foi o inteiramente casualizado, com cinco tratamentos (0, 90, 180, 270 e 360 dias de armazenamento) e cinco repetições, sendo cada uma composta por uma embalagem. Os dados foram submetidos à Anova e teste de Tukey a 5%. Com exceção do índice de refração houve diferença significativa entre os tratamentos para todas as variáveis, com aumento dos ácidos graxos... |

Markets for agricultural products may be inefficient when signals do not adequately reflect product characteristics important to market participants. Although preferences can be explicitly stated through price premiums or characteristic values can be determined via hedonic methods, the problem is compounded when product quality information is costly to obtain. Bundling of quality traits by variety can serve to signal product quality. A procedure is developed in this paper to derive the value of different varieties in meeting buyer demands. An application to the hard red spring market wheat both validates the ability of the procedure to distinguish among varieties, as well as provides empirical support to the existence of Akerlof's lemon market in the... |

The challenge of implementing EU quality and safety standards for food production and trading is one of the driving forces behind the restructuring of the agrofood chains in Central and Eastern European Countries (CEEC). The progress made in the compliance process not only varies amongst sectors and countries, but also among particular chains due to differences in their internal structure and strategies, and features of their political and economic surroundings. We construct a models to identify determinants of the diffusion rate of standards in a food chain under pre-accession conditions. We argue that adoption decisions in the food chain are determined by farmers' and processors' economic considerations. Factors such as pricing behavior, compliance costs... |

ABSTRACT This study analyzes the effect of different levels of expeller copra meal (ECM) in animal protein-based diets with enzyme on the haematology, carcass and fatty acid composition of broilers. One hundred and sixty 20 days old Cobb broilers were assigned 8 different diets, 2 of them being controls and 6 others containing ECM at 150, 300 and 450 g/kg, with or without enzymes. Four replicate cages of 5 birds each were fed the diets in a completely randomized design. Higher white blood cell (WBC) counts were obtained in chickens fed the control and 150 g/kg ECM with enzyme (p<0.05) diets. Meat saturated fatty acids (SFA) content increased on the 150 g/kg diet and later decreased above 300 g/kg without enzyme (p<0.05). Monounsaturated fatty acid... |

In a marketing environment, the demand conditions, the costs of shipping and storing grain varieties, the interest rate on farm loans, and the distribution of cropland in the area are important determinants of growers' planting decisions. In this article, I focus on a market for two quality-differentiated agricultural commodities: one produced with the use of biotechnology and the other, without. I develop a model for analyzing the equilibrium planting and marketing decisions made by geographically dispersed producers during the marketing year following harvest. I identify the types of marketing environments leading to a greater concentration of equilibrium acreage planted to a particular grain variety near the market and investigate the effects of the... |

This study deals with horizontal product differentiation in the Polish pig meat market. Hypothesis among firms behaviour are derived from an illustrative model and tested in an empirical analysis using data from 1991-1998. The empirical analysis suggest that product differentiation is a relevant phenomenon in the polish pig meat markets. In addition we found that costs and competitions are important factors influencing price variation. However, further influences like price discrimination and vertical product differentiation are also important determinants for product price variations. |
