Variación del residual de sulfito en el camarón de cultivo Litopenaeus vannamei almacenado en hielo
The absorption and loss of the sulfhite in the shrimp has great importance in their post-crop handling, since the sulfhite residual can give a measure of the protection that presents the shrimp against the appearance of the melanosis. Shrimps were taken and underwent to a treatment in solution of MBS to 8 % using different times of immersion, being determined the residual of sulfhite in the product obtained in each case. Additionally, the shrimps tried during five minutes were placed in plastic containers with ice in proportion 1:1, those that were storaged in a refrigeration camera to a temperature between 7 and 10 °C during five days. The residual ones were determined every day with the objective of quantifying the losses that take place during the storage in ice. Later the curves of absorption and loss of MBS were obtained and the mathematical models were determined that explain this processes. It was observed that the biggest absorption takes place in the first minute of immersion. In the process of loss it was known that to the six days of storage in ice, the residual of sulfhite had shrunk in 93 %.
