Resumo: dc.description.abstract | The fish, which is a perishable product, to go a long way to commercialization, it is ideal to be frozen as soon as possible. The glazing consists of a thin layer of surface ice added to the fish. It is an industrial process performed after freezing and aims to protect the fish gutted and skin dryness and oxidation caused by contact of tissues with oxygen. In order to profit illegally, many manufacturers increase the weight of the product incorporating water at this stage, with amounts above the limit of 20% of the product weight, tolerated by the Ministry of Agriculture, Livestock and Supply (MAPA). As a goal, this study evaluated the percentage of net loss in the melting of tilapia fillets brands A and B, performed in triplicate for three lots. To obtain the Product weight frozen (Pwf) was performed weighing the Gross Product (GP), subtracting the weight of the package (Wp). The product without packaging was placed in a strainer and submerged in chilled water. After removal of the glazing, the fillet is superficially dry, obtaining the Product weight thawed (Pwt). The percentage of glazing was calculated using the weight thawed (Wt) subtracted from the weight frozen (Wf), and finally divided by GP. For the brand, the incorporation of water was not exaggerated, because its percentage of glazing was 7.04%, however, to brand B, this value was 26.44%, which extrapolates the current recommendation, demonstrating iniquity thereof. The real price for Filet A was R$10.53 and R$6.61 for B. The weight of the packaging filet was certified in 400g packages in all of those lots. The weight of the fish of brand A after removal of the glazing ranged from 377.48g to 397.80g, while for the mark B ranged from 248.93g to 348.52g with water loss of about 150g. Thus, only the brand remained within the required parameters. It is recommended, therefore, which makes the control of each processing step, for companies to standardize their procedures according to the needs of the product in order to meet the criteria in effect by legislation. | pt_BR |
