This study aimed at evaluating the physical, chemical and microbiological characteristics of Uba mango and guava, as well as validates a model of traceability through the use of software developed by Ramos et al. (2007) for organic "Uba" mango production chain. The identification of producers and agribusinesses located in the Zona da Mata's microregion was performed in order to characterize the production and processing of "Uba" mango and guava. In addition, questionnaires covering relevant technical data were elaborated in order to generate the information required to mango and guava characterization. Microbiological, physical and chemical analyses were performed to assess the quality of the fruit along the production chain. The validation of the Traceability System (SR) for "Uba" mango production chain was done with the organic "Uba" mango farmers' collaboration from Guidoval municipality in an agribusiness chosen as a pilot. Information about the field (production, harvesting and post-harvest), maturation hangar (product used for maturation and the responsible for it) and agribusiness (customer base, inputs, suppliers and processed products) were inserted into the database. After the questionnaires' analysis, it was possible to verify that there was a heavy traffic of people, vehicles and animals such as chickens, pigs and dogs at the mango ranch; most of the properties (70%) had fruit ripening sheds. Mangoes were harvested before their complete maturation and it was completed during their storage in the sheds; the sheds' structure was precarious; the harvest of the fruit was held only once a year during the period from November to January. The main variety of guava grown in the region was Paluma; and regarding the infrastructure of guava producing properties, it was observed that 75% of the properties do not have shed to the fruit selection. After analyzing the questionnaires it was possible to verify that most of small and medium sized agribusiness produce juice, nectar and pulp. The microenterprise concentrates in sweets production. The agribusinesses men interviewed face problems with guava and mango acquirement due to the lack of standardization regarding the point of ripeness and seasonality. The microbiological analysis of mango revealed that the maturation shed is a point of the fruit's contamination. The microbial load increased significantly at this point of the chain and it continued to develop along the transport. The physical and chemical analysis performed in the mango and guava showed that they are within the standards established by law and are suitable for the production of pulp and its derivatives such as juices and nectars. The organic "Uba" mango is grown by small farmers and hoses on each property are reduced in number. During the study it was noted that the database needs some modifications and improvements in order to implement the Matching System (SR). The system does not allow a quick search in the files. It should be able to send files by e-mail through the software. For example, the Maturation Hangar mode in the software requires that the information about the local hygiene, insects and rodents control and the local cleaning frequency must be inserted in the program.
