In the face of a major global drinking water crisis, it becomes increasingly important to raise concerns on the use of sustainable techniques, mainly those aiming at saving potable water, especially in the seafood industry, that consumes significant amounts of water resources. In this context, the aim of the present study was to carry out industrial water management, quantifying and qualifying effluents from the general activities of a seafood processing industry, in order to identify which effluent exhibited reuse potential. Water use (water balance) was measured at six fish processing steps, and effluent physicochemical and bacteriological analyses were carried out. Direct reuse was not indicated for any of the analyzed effluents, mainly due to high levels of total coliform bacteria (104 to 107 MPN/100 ml). However, indirect water recycling and reuse can potentially be applied after a simple effluent primary treatment and disinfection from the freezing tunnel and cooling chamber defrosting, in order to supply cooling tower demands. This practice may reduce the total average water consumption of the processing unit by 11% and, if the effluents from the cooling tower purges were to also be reused for other administrative ends, this reduction may reach 21.9%, enhancing the competitiveness of this industry and preserving fresh drinking water. |

The causes of the low desiccation tolerance and low longevity of coffee seeds have not yet been fully elucidated, and a full understanding of their complex physiology is of great interest. Among several alternatives, the loss of antioxidant capacity in seeds may be related to their rapid loss in quality during storage. The objective of this study was to determine the total antioxidant capacity of coffee harvested at different ripeness stages before and after the storage of seeds with different water contents and to relate antioxidant capacity to physiological quality. Seeds in the greenish-yellow or cherry stages, recently harvested or stored for nine months at 10 °C with 40, 30, 20 and 12% water content (wet basis ? wb), were submitted to physiological and biochemical quality evaluations, and the Trolox equivalent antioxidant capacity (TEAC) was determined. The germination and root protrusion of coffee seeds from greenish-yellow and cherry fruits were not affected by drying, but seeds harvested at physiological maturity had greater vigor when the moisture content was lower. The quality of coffee seeds decreased during storage, and this decrease was greater in seeds stored with higher water contents. Coffee seeds in the greenish-yellow stage had a higher antioxidant capacity than those in the cherry stage when recently harvested, but there was a substantial reduction in this capacity during storage at both maturation stages. Coffee seed deterioration is related to a reduction in antioxidant capacity, and the isoenzymatic profiles of the antioxidant process are little affected by the seed maturation stage. The deterioration of coffee seeds during storage is related to a reduction in their total antioxidant capacity, regardless of their maturation stage, being more pronounced in the greenish-yellow stage.
