Efeito do processamento sobre os níveis de colesterol e 7-cetocolesterol em camarão-rosa

Abstract: 117Colesterol em camarão processado, Moura e Tenuta-Filho -INTRODUÇÃOO colesterol encontra-se distribuído nos tecidos animais como principal esterol. Desempenha funções estruturais e funcionais nas membranas celulares, sendo o precursor dos ácidos biliares e hormônios esteróides. Como lípide insaturado, está sujeito à oxidação, gerando óxidos biologicamente ativos. Existem evidências da participação de óxidos de colesterol em vários processos caracterizando-os como citotóxicos [24,25] Os alimentos de origem a… Show more

“…Free radicals generated by the process of lipid peroxidation co-oxidize several molecules, especially cholesterol which is in the lipid fraction and membranes of animal tissues. The production of cholesterol oxides has also been observed in shrimp that has been processed by others methods such as boiling or deep-frying (MOURA; TENUTA-FILHO, 2002). However, the lowering of cholesterol levels was not observed in the present study, probably due the frozen (-20 °C) condition of the samples during irradiation.…”

“…The most important unsaturated fatty acids in shrimp are eicosapentaenoic (20:5, EPA) and docosahexaenoic (22:6, DHA), which are also considered as essential fatty acids. Moreover, shrimp is a good source of minerals such as calcium, and it is also considered a high cholesterol food (MOURA; TENUTA-FILHO, 2002).…”

“…Foi constatado que a quantificação do Camarão Vila Franca apresentou níveis superiores, quando comparada ao do Camarão Rosa, no entanto, foram semelhantes. Corroborando tal achado, Moura (2002), ao avaliar o teor de colesterol em camarão in natura, detectou 151mg/100g, muito próximo ao teor do Camarão Rosa do presente estudo. Ainda, Philippi ( 2002) mensurou e disponibilizou em sua tabela de composição de alimentos um teor de 152mg de colesterol em 100g de camarão in natura, o mesmo teor detectado pelo presente estudo.…”

“…Simon et al (2012) recorded a lower lipid level (0.86-1.4%) in L. schimitti. Other research recorded a lipid value at 1-1.34% in Penaeus brasiliensis, P. monodon and P. vannamei (Moura and Tenuta, 2002;Sriket et al, 2007;Li et al, 2011;Puga-Lopez et al 2013;Bragagnolo and Rodriguez-Amaya, 2021). It is noted that the chemical composition in marine fish can vary between species and within the same species because of the effects of several factors, including diet, density, growth stage, quality and salinity of the water and seasonal changes (Saldanha et al, 2006;Sriket et al, 2007).…”
