The study aimed to evaluate whether the addition of pequi increases the nutritional value of meatballs made with piranha and pacu fillets. Piranhas were obtained from the colony of fishermen; pacu with the fish farmer and the pequis were collected in nature. Fish were filleted and triturated, and the resulting masses were used to prepare 4 types of meatballs: piranha fillet with 2.0% pequi pulp, piranha fillet without pequi pulp, pacu fillet with with 2.0% pequi pulp, and pacu fillet without pequi pulp. After preparation, acceptance, purchase intention and frequency of consumption were evaluated with untrained tasters. Chemical composition parameters evaluated were crude protein, lipids, ash, moisture, carotenoids and antioxidant activity. Results of acceptability for all formulations were similar. The chemical composition of piranha meatballs presented differences (p < 0.05) for lipids and carotenoids. Pacu meatballs showed no difference (p > 0.05) for moisture, carotenoids, and antioxidant activity. The addition of pequi did not alter the organoleptic characteristics, however increased the nutritional values, therefore, it can add value to the product to be marketed and be more nutritionally attractive to the consumer.(AU)

This work researched and compared the contamination by enteroparasites in lettuce (Lactuca sativa) commercialized in the supermarkets and street markets of Campo Mourão, State of Paraná. 150 samples of lettuce were analyzed through sedimentation method (Hoffmam), being 75 samples from supermarkets and 75 from street markets. The sediment was analyzed in optic microscope. The supermarkets samples showed contamination by parasites of 56% (42/75); while contamination of street markets samples showed 58.7% (44/75). The principal parasites observed in supermarkets samples were: Ascaris spp 54.7%, Toxocara spp 2.4%, Strongyloides spp 4.8%, Entamoeba spp 35.7% and Taenia spp 2.4%. Important parasites observed in street markets were: Ascaris spp 13.6%, Strongyloides spp 11.4%, Entamoeba spp 47.7%, Ancylostoma spp 9.1%, Taenia spp 2.3%, Fasciola hepatica 6.8% and Trichuris spp 9.1%. These results indicate that the samples of lettuce are in disagreement with current law and point out the necessity of a sanitary education program for vegetable producers and vegetable manipulators
Este estudo investigou e comparou a contaminação por enteroparasitas em alfaces (Lactuca sativa) comercializadas em supermercados e feiras livres do município de Campo Mourão, Estado do Paraná. Foram analisadas 150 amostras de alfaces, pelo método de sedimentação espontânea (Hoffmann), sendo 75 amostras provenientes de supermercados e 75 amostras de feiras livres. O sedimento foi analisado em microscópio óptico. Das amostras analisadas, 56% (42/75) e 58,7% (44/75) apresentaram contaminação por parasitas, dos supermercados e feiras livres, respectivamente. Os principais parasitas encontrados em supermercados foram: Ascaris spp 54,7%, Toxocara spp 2,4%, Strongyloides spp 4,8%, Entamoeba spp 35,7% e Taenia spp 2,4%; e em feiras livres foram: Ascaris spp 13,6%, Strongyloides spp 11,4%, Entamoeba spp 47,7%, Ancylostoma spp 9,1%, /em>Taenia spp 2,3%, Fasciola hepatica 6,8% e Trichuris spp 9,1%. Esses resultados indicam que as amostras de alfaces estão em desacordo com a legislação vigente e salientam a necessidade de aplicação de um programa de educação sanitária direcionado a horticultores e manipuladores de hortaliças
