“…Sacha inchi leaves and oil, as well as the presscake produced using oil extracted from its seeds, are an excellent option of a sustainable ingredient for omnivorous fish feeds. Cold pressed sacha inchi oil has high commercial value and is non-toxic to animals (Gorriti et al 2010), making it a suitable ingredient for animal nutrition. In Amazonas state, in northern Brazil, tambaqui and matrinxã farming is an important small family business (Almudi and Pinheiro 2015), therefore there is a demand for the use of local, low-cost ingredients in tambaqui and matrinxã feeds, since conventional ingredients are expensive and come from different regions, increasing production costs (Dairiki and Silva 2011;Dairiki et al 2013).…”

Sacha inchi (Plukenetia volubilis) is a plant native to the Peruvian Amazon with seeds that contain 24 to 29% protein, and levels of vitamin A and E and omega 3 polyunsaturated fatty acids that are suitable for fish nutrition. Thus, this study aimed to evaluate the use of sacha inchi seeds as an ingredient in the diets of tambaqui (Colossoma macropomum) and matrinxã (Brycon amazonicus). The acceptance and effect of three levels of sacha inchi seed meal (0, 15 and 30%) in fish feed was evaluated in a randomized experiment, testing groups of 12 juvenile tambaquis (29.8 ± 1.0 g, 11.0 ± 1.4 cm) and groups of eight juvenile matrinxãs (34.8 ± 1.3 g, 13.7 ± 1.0 cm). Growth performance and body composition of the fish were determined at the end of the experiment. An effect of the sacha inchi diet was only observed for feed conversion of tambaquis, which was worst at the highest level of sacha inchi seed. In conclusion, sacha inchi can be added to feed juvenile tambaquis at a level of 15%, and juvenile matrinxãs at 30% without compromising growth performance and body parameters of the fish.KEYWORDS: alternative diet, growth performance, nutrition, fish Sementes de sacha inchi (Plukenetia volubilis, Euphorbiaceae) em rações para juvenis de tambaqui, Colossoma macropomum, e matrinxã, Brycon amazonicus (Characidae) RESUMOSacha inchi (Plukenetia volubilis) é uma planta nativa da Amazônia peruana cujas sementes contém 24-29% de proteína, além de vitamina A e E e ácidos graxos polinsaturados ômega 3 em níveis adequados para a nutrição de peixes. Dessa forma, este estudo teve como objetivo avaliar o uso de sementes de sacha inchi como ingrediente em rações para o tambaqui (Colossoma macropomum) e matrinxã (Brycon amazonicus). Níveis de inclusão de sacha inchi nas rações e aceitação foram avaliados em um delineamento experimental inteiramente aleatorizado, avaliando três grupos de 12 juvenis de tambaqui (29,8 ± 1,0 g; 11,0 ± 1,4 cm) e três grupos de oito juvenis de matrinxãs (34,8 ± 1,3 g; 13,7 ± 1,0 cm) alimentados com rações contendo 0, 15 ou 30% de farelo de sementes de sacha inchi. O crescimento e a composição corporal dos peixes foram avaliados ao final do experimento. Um efeito da ração com sacha inchi foi somente observado para a conversão alimentar de tambaquis, que foi pior no maior nível de semente de sacha inchi. Em conclusão, sacha inchi pode ser adicionada na alimentação de juvenis de tambaqui até o nível de 15% e na de juvenis de matrinxã até 30% sem comprometimento do desempenho e dos parâmetros corporais.

“…Sacha inchi (Plukenetia volubilis) is an oilseed found in the Peruvian Amazon and various studies have been conducted to characterize and process its oil since 1992 [1][2][3][4][5][6][7]. The oil is obtained using different methods of extraction, including Soxhlet, cold pressing and supercritical carbon dioxide (SC-CO 2 ) [2,4,5].…”

“…The presence of unsaturated fatty acids in the oil makes it an excellent source of omega-3 and omega-6 essential fatty acids (linoleic and a-linolenic acids) and consequently a potential source to promote health benefits [8]. The studies performed to characterize the oil include physico-chemical properties, chemical composition, thermal properties, toxicological effects and phase behavior in SC-CO 2 [2][3][4][5][6][7].…”

Sacha inchi (Plukenetia volubilis) oil has high polyunsaturated fatty acids content. The hydrolysis of this oil is an efficient way to obtain desirable free fatty acids (FFA). The optimization of parameters was carried out according to the maximum production of FFA using two enzymatic hydrolysis processes. The effect of enzyme concentration (5-40 % based on weight of oil), temperature (40-60°C), and oil:water molar ratio (1:5-1:70) were studied for the conventional enzymatic hydrolysis process, while pressure (10-30 MPa) and oil:water molar ratio (1:5-1:30) were studied for the enzymatic hydrolysis in supercritical carbon dioxide (SC-CO 2 ) media. The hydrolysis in SC-CO 2 media resulted in higher production of FFA (77.98 % w/w) at 30 MPa and an oil:water molar ratio equal to 1:5 compared to the conventional process (68.40 ± 0.98 % w/w) at 60°C, oil:water molar ratio equal to 1:70, and 26.17 % w/w, enzyme/oil. The only significant parameter on the production of FFA for conventional enzymatic hydrolysis was enzyme concentration, while for the hydrolysis in SC-CO 2 media both pressure and the molar ratio of oil:water were significant. Lipid class analyses showed that with both methods, FFA, monoglycerides, and diglycerides content in the final product increased compared to pure oil, while triglycerides content decreased. Fatty acid composition analysis showed that the content of fatty acids in the FFA form were similar to their triglyceride form.

RESUMENEl objetivo de este estudio fue determinar los efectos de la torta de sacha inchi (TSI) en diferentes niveles de la ración de pollos sobre el perfil bioquímico sanguíneo, consumo de alimento (CAL), conversión alimenticia (CA) y ganancia de peso (GP), peso relativo de órganos e histología del hígado. Para esto se utilizaron 150 pollos (75 hembras y 75 machos) de 2 días de edad, de la línea Cobb 500, los cuales fueron divididos en 3 grupos o tratamientos (T1, T2 y T3). El T1 fue alimentado con 0%, el T2 con 7% y el T3 con 14% de TSI. Las muestras de sangre fueron obtenidas a los 2, 12, 21 y 48 días de edad; el diseño estadístico usado fue el DCA con arreglo factorial 3x3+1. Los perfiles bioquímicos sanguíneos bajo efecto de la TSI fueron: 27.38±0.38, 30.00±0.38 y 29.56±0.45 de hematocrito (%); 2.86±0.10, 104.51±2.44, 92.74±1.96 y 92.53±2.29 de AST (UI/L); 30.81±3.32, 17.82±0.66 y 20.95±0.62 de ALT (UI/L) para T1, T2 y T3 respectivamente. Los niveles de TSI en la dieta no mostraron efecto (p>0.05) sobre los perfiles de hemoglobina, albúmina, proteína sérica, mientras que en los niveles de hematocrito, AST y ALT si tuvo efecto (p<0.05); pero los resultados mencionados se encontraron dentro de sus parámetros normales. En cuanto a CAL, CA y GP los niveles de TSI mostraron efecto adverso (p<0.05). La TSI tuvo efecto hepatotóxico, mas no así sobre el peso relativo de los órganos estudiados (p<0.05).PALABRAS CLAVE: Sacha inchi, Plukenetia volúbilis L, perfil bioquímico sanguíneo. DETERMINATION OF THE EFFECT OF SACHA INCHI (Plukenetia volúbilis L.) CAKE FEEDING ON BLOOD BIOCHEMICAL PROFILE OF BROILERS ABSTRACTThe aim of this study was to determine the effect of sacha inchi cake (SIC) in different levels of the diet of broiler chickens on the serum biochemical profile, feed intake (FI), feed conversion (FC), weight gain (WG), internal organs relative weight and liver histology. For this purpose, we used 150 Cobb-500 2-day-old broilers chicken (75 males and 75 females) which were divided in 3 treatments (T1, T2 and T3). T1 was fed 0%, T2, 7% and T3, 14% of SIC. Blood was sampled from yugular vein at 2 days old and wing vein at 12, 21 and 48 days old; a complete randomized design with a factorial 3x3+1 was used. The serum biochemical profiles under the PCSIC effect were: 27.38±0.38, 30.00±0.38 y 29.56±0.45 for hematocrit; 104.51±2.44, 92.74±1.96 y 92.53±2.29 for AST; 30.81±3.32, 17.82±0.66 and 20.95±0.62 for ALT for T1, T2 y T3 respectively. Levels of SIC did not show effect (p>0.05) on hemoglobin, total protein, albumin, meanwhile, while these showed effect (p<0.05) on hematocrit, AST and ALT, but these results were between normal levels. SIC had negative effect on FI, FC and WG in T2 and T3 (p>0.05) but did not had influence on the studied relative weight of internal organs (p>0.05). Liver tissue showed polynunleated hepatocytes in T2 and T3. In conclusion, SIC changed the hematocrit, AST and ALT levels and had hepatotoxic effect in liver tissue, feed intake, feed conversion and weight gain of broiler chicken when ...
