[Elaboration of a dried-salted and smoked product using aquaculture species].
The purpose of this work was to adapt the procedure developed at the Instituto Nacional de la Nutrición Salvador Zubirán (INNSZ) for the conservation of the sardine to aquaculture species such as carp (Ciprinus carpio) and tilapia (Tilapia sp). The mixtures were designed on the basis of the chemical score method. The preparation of the patties included different fish presentations, and two methods were evaluated in order to obtain fish pulp. In the formulation of the final product, defatted soy, maize and wheat flour were included, as well as three different mixtures of condiments, which were then compared to the original formulation based on sardine. The raw materials and final products were subjected to sensory evaluation and to a shelf-life study. The results indicated that for these species, to obtain the fish pulp it is necessary to include one phase of the procedure, which can be manual or mechanical, because there are no significant differences between them. The formulations selected were: flour corn (10%)--flour soy (30%)--carp (60%), and flour corn (10%)--flour soy (22%)--tilapia (68%). In both cases the condiment mixture was eliminated, and only common salt was used. The protein content was of 40g/100g of the dry product, with a minimum shelflife of 12 weeks at room temperature (22 degrees-23 degrees C). During this period no rancidity developed, the product was microbiologically adequate for human consumption, and proved to have a higher sensory acceptance than sardine patties.
