Extracción de colágeno de las escamas de pescado utilizando diferentes niveles de rennina

Abstract

At ESPOCH, Animal Science Faculty, Animal Nutrition and Bromatology Laboratory, collagen from fish scale using different levels of Renin (5, 10 and 15%) was extracted using 15 experimental units divided into three treatments with 5 repetitions that were distributed under a completely randomized design; the results were analyzed through ADEVA and Tukey test. It was evidenced that the levels of Renin did not influence in the Bromatological composition, but conductivity was higher when using Renin at 15%. The collagen organoleptic valuation did not reflect any statistical difference although numerically with renin at 5% it was possible to obtain a better acceptance (12.50/15 points). With a use of 15% the production cost was less (0.09 dollars/gram). At the same time a better economic profitability was achieved (Cost/benefit 1.43), thus it is recommended to use this level of renin to extract collagen from fish scale.
