Avaliação da Qualidade de Pêssego em Calda de Marcas Nacionais “Tipo Especial”e Importadas, das safras 1999/2000 e 2010/2011.

Abstract

The development of Brazilian fruit, especially peaches in syrup "special type", produced and industrialized in Pelotas, focuses on quality improvement and income generation and direct and indirect jobs. Sustainability in the production process and the competitiveness of canned peaches industrialized nationally are factors that are linked to the productive chain of peach, this factor of economic relevance for the Southern Region of Brazil, especially for the city of Pelotas, which is featured in the production of canned peaches, contributing about 80% of product that supplies the domestic market. Local industries have been given as premises remain in the market and overcome obstacles posed by the opening of the domestic market and globalization that brought canned peaches imported from various sources, including Greek and Argentina. This study aimed to compare the evolution of the quality of canned peaches "special type" national, produced in Pelotas / RS, (six brands) with canned peaches imported from Greek and Argentina (four marks for the first harvest and three evaluated for the second season), 1999/2000 and 2010/2011 seasons. Through analytical and sensory determinations sought to detect changes and / or improvements in the national product, represented by the local industry, compared to the imported product in the running of the last decade. In the test ordering by preference, look for the attribute, we used a hedonic scale of 1 (least liked) to 10 (like most), the first season and 1-9 in the second season, and for both, highlighted the preference of consumers for the appearance of imported brands due to the larger size and more even skin tone. For flavor and texture, the scale used was from 1 (least liked) to 5 (like most), evaluated in the first season and 1-4 in the second. It is the preference of consumers in the two seasons, the taste of the national brands, characterized by greater sweetness, arising from the right stage of ripeness of the fruit, acidity and adding mixtures with higher concentrations of sugars. The size and thickness of imported peaches, although larger than those of domestic origin, were not decisive in consumer preference for the attribute texture. The determining factors to obtain a firm texture with intermediate preferred by the judges, were the correct fruit ripening and proper processing. Peaches in syrup of national origin had higher vacuum, higher number of defects, thinner, smaller diameter, lighter weight and greater number of halves of halves of the imported brands. The drained weight of the product was lower than the national and imported brands of domestic and imported crops 99/00 and 10/11 showed no difference in the chemical composition of nutrients. It was concluded that the processing industries in the region of Pelotas / RS do not have adequate quality standards and / or does not maintain a strict monitoring at all stages of processing peaches in syrup.
