Avocado (Persea americana Mill.) is a product grown in tropical and subtropical regions and from it we can extract products like guacamole which is highly consumed in the Mexican culinary. The most used varieties for guacamole are the Hass and Fuerte. The present research had as objective to evaluate the microbiological and sensorial quality of the guacamole conserved through cold with no addition of additives. The microbiological analyses have shown the product reached satisfactory results as for the analysis of total and thermoenduring coliform < 3,0 UFC/g, Salmonella absent in 25g, Staphylococcus aureus and Bacillus cereus < 100 UFC/g, presenting values within the patterns set by RDC of Anvisa 12 of January 2nd 2001. The analyses of mesophile bacteria and the counting of mold and yeast reached values between 102 and 104 UFC/g and the psychrotropic bactéria presented values < 100 UFC/g. The sensorial anlyses have shown that the polyethylene package isn't effective in keeping the analysed sensorial parameters. Although the polyethylene and nylon packages had better results, however they didn't differentiate themselves so as the vacuum use.
