TEORES DE LIPÍDIOS TOTAIS, ÁCIDOS GRAXOS E COLESTEROL EM RESÍDUOS DESIDRATADOS DE CAMARÃO-SETE-BARBAS ( Xiphopenaeus kroyeri, HELLER 1862) CAPTURADO NO ESTADO DO RIO DE JANEIRO

Abstract

Efetuou-se estudo sobre os lipídios totais, ácidos graxos e colesterol presentes resíduos desidratados de camarão, visando o aproveitamento total do crustáceo na alimentação humana. Resíduos de camarão-sete-barbas (cefalotórax, segmentos abdominais e caudas) foram lavados com água clorada, cozidos, desidratados, moídos e o produto final analisado. O teor de lipídios totais encontrado foi de 2,66% e o de colesterol de 98,82 mg/100 g. Do total dos ácidos graxos 34,43% corresponderam aos ácidos graxos saturados, 30,30% aos monoinsaturados e 35,26% aos polinsaturados. Os resíduos desidratados de camarão podem ser destinados à alimentação humana como flavorizante natural, conferindo sabor e aroma característicos ao alimento. LEVELS OF TOTAL LIPIDS, CHOLESTEROL AND FATTY ACIDS IN THE DEHYDRATED RESIDUES OF THE SEVEN-BEARDS-SHRIMP (Xiphopenaeus kroyeri, HELLER 1862) CAPTURED IN THE STATE OF RIO DE JANEIRO Abstract The production of shrimps in Brazil grew significantly in the last years and with excellent conditions for expansion. Although it is appreciated in the cookery, the shrimp is considered a food of high cholesterol tenor. The shrimp residues, when submitted appropriately to the cooking process, following by dehydration and reduction of particles can be destined to the human feeding as a natural flavor substance, checking to the food, flavor and aroma characteristic of shrimp. Occurred study on the total lipids, fatty acids and cholesterol, presents in total use of the crustacean in the human feeding. Residues of seven-beards-shrimp (cephalotorax, abdominal segments and tails) were washed with chlorinated water, cooked, dehydrated and grinded. In the obtained product the levels of total lipids, cholesterol and fatty acids were determinated. The total lipids and cholesterol contents were 2,66% and 98,82 mg/100g. From the total of the fatty acids 34,43% corresponded to the saturated, 30,30% to the monoinsatured and 35,26% to the polinsatured fatty acids.

Elaboration of Aromatic Extracts From the Industrial Waste of White Shrimp

“…Evaluating the viability of flour preparation obtained through the drying process of shrimp cephalothorax of the L. vannamei species, Savay-da- Silva et al (2016) found an ash value of 18.28%, while Mendes and Bandeira (2016), when evaluating the ash content in gray shrimp meal, obtained values of 17.77%, values close to the extract obtained from shells (E casca = 17.67%) reported in this research. According to Freitas, Borges, Costa, Cornejo and Wilberg (2002), the high content of ash in the flour and consequently in aromatic extract shows a potential of these products for use in diets for special purposes.…”

“…According to Luzia, Sampaio, Castelluci, and Torres (2003), the lipid content is influenced by seasonality, since significant differences between shrimp (Xiphopenaeus kroyeri) in summer (0.94%) and winter (1.16%) were evidenced by these authors. Still according to Freitas et al (2002), these levels may also vary according to age and degree of sexual maturation.…”

Reflexos da utilização de farelo de coco sobre o valor nutricional do filé de tilápia-do-nilo (Oreochromis niloticus Linnaeus, 1857)

“…A relação P/S é de extrema importância na elaboração de dietas, pois um excesso de ácido linoléico irá competir pelas dessaturases, comprometendo o teor de ácido graxo da série ω-3, tendo como possível consequência uma baixa produção de ácido eicosapentanóico (KRAUSS et al, 2000). Freitas et al (2002) chamam a atenção para a inadequação de dietas que levam em conta teores isolados de lipídios, relação P/S, ácidos graxos saturados ou poli-insaturados. …”
