The squid (Dosidicus gigas) is a cephalopod mollusk, a source of high quality proteins that is currently underexploited. The objective was to develop the methodology for the elaboration of a pre-cooked pota product, to evaluate the digestibility of the proteins and the shelf life of the product. Methodology: In a descriptive and experimental design, the nutritional technological study was carried out. Two samples of squid each consisting of 5 kg of the mantle, acquired at the Callao Fishing Terminal, were processed and analyzed independently. The process flow included: disinfection, cutting, washing, stabilization, cutting into strips, cooking by immersion in vegetable oil, packaging and storage. The physical and chemical analysis, using AOAC techniques; minerals using GBC Avanta atomic absorption spectrophotometer with graphite furnace. The digestibility by enzymatic method. The sensory...

La pota (Dosidicus gigas), es un molusco cefalópodo, fuente de proteínas de alta calidad que al presente está subexplotado1. El objetivo fue desarrollar la metodología para la elaboración de un producto pre-cocido de pota, evaluar la digestibilidad de las proteínas y la vida útil de producto. Metodología: En un diseño es de tipo descriptivo y experimental se realizò el estudio tecnológico nutricional. Dos muestras de pota cada una constituida por 5 kg del manto, adquiridas en el Terminal Pesquero del Callao, fueron procesadas y analizadas independientemente. El flujo del proceso comprendió: desinfección, trozado, lavado, estabilización, cortado en tiras, cocción por inmersión en aceite vegetal, envasado y almacenado. El análisis físico químico, mediante técnicas de la AOAC; los minerales empleando espectrofotómetro de absorción atómica GBC Avanta con horno de grafi...

The current study is an evaluation of Vitamin A supplement diet in female white mice Balb C53 inoculated with Sarcoma 180. The oral administration of a dose of 200 IU per day of Vitamin A in mice inoculated with sarcoma and divided in two groups, obtained a greater group B (vitamin A supplemented diet) mice survival curve than group A (normal diet) mice survival curve; however more studies are necessary to get a statistical significance. Liver concentration of catalasa was also quantified in three groups of mice: (1) healthy mice with normal diet; (2) sarcoma inoculated mice with normal diet; an (3) sarcoma inoculated mice with vitamin A supplement díet. It showed a significant difference of concentration of catalasa in group 2 in relation to group 1, unlike group 3 in relation to group 1. AH it indicates to us vitamin A anti-oxidant action, avoiding that the enzyme levels decreases. To...
