Information on the presence of 2- Alkylcyclobutanones in animal feed after ionizing radiation treatment.

Disponível em: http://repositorio.ipen.br/handle/123456789/28318.http://repositorio.ipen.br/handle/123456789/28318In agribusiness, it is related to the development of the activities of creation, production and commercialization of pets in the Pet segment. This market grew 7.6% between 2014/2015, generated R$ 18 million in Brazil and 67.3% of this value refers to products for animal feed, commonly called pet food. In animal feed, the raw materials are chosen according to the method (s) of processing (s) in which the product is submitted, its stability in the process and its nutritional source during the validity of the product. In food preservation, the irradiation process is a treatment that seeks to reduce the microbial load of foods, however, it can also alter the composition of the present ingredients and form radiolytic products in the formulation that are still under study. In products containing the presence of fat, the main concern is 2-Alkylciclobutanones (2-ACBs), which are radiolytic products formed exclusively post-processing with ionizing radiation. The formation of 2-ACBs is directly related to the lipid concentration and the dose of irradiation. The objective of this work is to describe the possible radiolytic by-products formed in canine rations containing extruded fat after irradiation and to determine if the formation of 2-ACBs depends on the increase of the radiation dose and, as a consequence, verify their cytotoxicity and genotoxicity.openAccessanimal feedscarboxylic acidsfatsfood processingirradiationmycotoxinsquality controlTexto completo de eventohttps://orcid.org/0000-0001-6199-7877
