Resumo: |
The Cerrado is the source of much of the richness of both fauna and flora, which represent Brazil and some countries in South America. Among the individuals of the flora, much has been studied about fruit plants. Therefore, this study aims to analyze the potential of endemic Mangroves (Harconia speciosa Gomes) of the cerrado, a fruitful plant, very productive, with a pleasant taste and that can occur in up to six varieties. Three varieties were initially defined for study: var. Gardneri, cuiabenses and pubescens. These varieties were initially studied for their physiological development for three harvests. These plants, besides production in the harvest period, produce fruit during several months of the year and apparently the productive peak between the varieties is not the same. The flowering of September of a given year is responsible for the fruits of July next year. Evaluating the post-harvest, it was noticed that if fruits of fall were collected the durability of these will be of maximum 3 days, whereas, fruits collected in the mother plant will have durability of nine days. In view of this, it was necessary to test technologies for post-harvest conservation among them, refrigeration and the use of edible cover. In refrigeration the mango fruits stored at 5ºC could last up to 25 days, with var. Pubescens appears to be more resistant to catabolic changes from ripening when refrigerated. When applied to the edible coatings of starch and whey protein, it was noted that the protein coating was more successful in preventing loss of fruit mass, maintaining appearance and lasting about ten days. Evaluating the possibility of collecting the fruits in the mother plant and standardizing its maturation, exogenous ethylene was also tested and it was verified that this is feasible to standardize the ripening, the indication was treated by immersion in a dosage of 520 mgL-1. After the harvest, the possibility of processing this fruit was also evaluated and a sorbet diet and without mango lactose and a nectar were prepared. In both cases, it was possible to note that the fruit has potential for processing because it presents, besides desirable physicochemical parameters (acidity, soluble solids and ratio), a high ascorbic acid content, classifying the fruit as rich in vitamin C. It is concluded Finally, that mangaba is a fruit of commercial importance and that post-harvest care can be achieved with already widespread technologies, such as refrigeration, or more recent but equally simple technologies such as edible coverages or use of exogenous ethylene. |
