Evaluacion del proceso de elaboracion de conservas de pescado "trucha arcoiris " (Oncorhynchusmikiss) contenidasen envases de hojalata en la parroquial el tingo la esperanza

This research is based on studying the process of canning fish Rainbow trout (Oncorhinchusmikiss) using DDE tin containers with liquids of different government more vegetables. Trout is a perishable commodity, which is exposed to attack by bacteria and microorganisms. Today there is an appropriate and safe to keep the product longer, as is canned, as it is a very appropriate choice for agroindustrial production. The most important thing is that it preserves not need additives, preservatives and who undergoes thermal process to destroy microorganisms that s found therein. The fish as a healthy food because it contains a rich source of phosphorus, magnesium, iron, zinc, iodine and also with minerals and vitamins, trout also justifying contributes protein consumption. This work was performed at the meat shop of the farm "La Maria", belonging to the State Technical University Quevedo, located at Km 7 1/2 way to splice, Canton Mocache, Rivers Province. The main objective of this research is to evaluate the process of making preserves of rainbow trout (Oncorhynchusmikiss) contained in tinplate, applying a design Factoría A * B * C, where A: liquids of government B: conditioning of matter Prima and, C: time and temperature applied in the autoclave, with 2 repetitions. To determine difference between levels of study I was found significance, was performed the test of Tukey to 5%. For the development of this research we proceeded to perform the reception of the feedstock, then the washing and eviscerated of fish, again washed for withdraw impurities, by another part was begun to package the fish already cut in the two forms (integers and filleted) in each lata, after this took to a pre cooking by 7-10 minutes, then was added the liquid of government more vegetables, to spend to sealing and proceed to sterilize the product and, lastly cool and store. As variables is took the following: pH, Concentration of salt, Protein, Histamine, Density, Analysis sensorial (smell, color, flavor, texture and juiciness), in Concerning the analysis was performed to best treatment. The processed product "conserves of trout", was exposed to the evaluation sensorial through a group of 5 tasters chosen for study and descriptive scales elaborated for the case, with the purpose of determine treatment its disposal dde greater acceptance by the consumer . El balance matter was applied to best treatment which is the number 10 (a2boc1) which corresponds to: liquid of government in SLASA of tomato more vegetal, whole fish and time and temperature of 90 'to 90 ° C. Conditions by which presented the following variables: Histamine 0.25%, pH 6.16, Proteins 16.60, Sodium chloride 1.54, besides excellent sensory characteristics as are: color (2.8), Odor (2 , 2) flavor (3.8) texture 3,2 and juiciness (14.4). In what regards the economic analysis was conducted in function of the materials and equipment for the best treatment tomato sauce more vegetables selling price of each lata of 395 grs. is $ 3.02, the benefit with relationship at cost is $ 0.19, which not ole allows compete in the market, already like products exist at prices more acceptable.
