Caracterização física, química e avaliação da toxicidade do caroço do abacate (Persea Americana Mill).

Abstract

The waste and contribute to the generation of waste is linked to other social problems such as hunger and malnutrition, facts that motivate studies to increase the use of food and even its full use, to improve the nutritional value of meals , reduce environmental impacts and consumer spending. By consuming fruits like avocado, often used only the pulp of the fruit, being discarded the shell and the seed. In the literature already show the presence of important nutritional compounds both in the shell and in the avocado seed. Thus, this study was developed in order to characterize physically and chemically and assess the toxicological potential of the avocado seed (Persea americana Mill) using the bioassay Artemia salina Leach, aiming at developing flour and possible application in product development food. The results relative to the total mass of the fruits varied from 0.39 kg 0.33, consisting of 16.7% of seed, pulp 50% and 33.3% peel. The value found in the pulp pH was 6.80, titratable acidity of 1.10% and 82.63% water content. The results showed that have significant values potassium present in the core as compared pulp and film that covers the core. The CL50 value found for the seed extract was 452,57ppm while the film was above 1000ppm. The seed had a moderate toxicity, the film was considered non-toxic, which allows it to be used for the production of new food products and safe for human consumption
