Desenvolvimento de um composto de erva-mate contendo folhas de Olea europaea L

Abstract

The oliviculture are in contantly development in the Estate of Rio Grande do Sul, it is an industry that generate a serie of leftover, between them the Olea europaea L comunly known as oliveira’s leaf. The present dissertation it’s about an invention composed of erva-mate (Ilex paraguasiensis ST Hil.) and leafs of Olea europaea L, two raw materials capable of provide benefits to the human healthy, according to studies. Therefore, with the objective of develop a new product coming from the incorporation of the erva-mate with leafs of Olea europaea L. was maken laboratorial tests such as: ethereal extract and cytotoxicity; besides those, it was realized tests of sensorial analyses with 100 evaluators which consume the chimarrão, in order to investigate the acceptability of the product, the intention of acquisition and the sensations in the moment of try the new product. Still, was realized a test to know which the ingestion of the product by the evaluators. Among the analised species in the test ethereal extract the percentual of embonpoint suffered a variation between 1,69% and 4,70%, being marginals variety, respectively, the Manzanilla and the Picual, and the intermediaries Arbosana, Frontoio, Arbequina, Coratina e Koroneiki. The test of cytotoxicity showed that the incorporation presents similar results to a compost of erva-mate that are present in the market. The product had 82% of acceptability and 84% of acquisition intention. The sensation more often perceived during the sensorial analyses was: good looking, gradable taste and watery. The evaluators consumed in average 20g of the product in each suction, including the incorporation and water. It was concluded that the incorporation of the Olea europaea L’s leafs in the erva-mate (Ilex Paraguariensis ST Hil) is capable of became a new product amenable to be patented, produced and inserted in the market. It is only suggested to be done sensorial and biological tests more deeply.
