- Antioxidative peptides: trends and perspectives for future researchPublication . Freitas, A. C.; Andrade, J. C.; Silva, F. M.; Rocha-Santos, T. A. P.; Duarte, A. C.; Gomes, Ana M. P.In recent years, much attention has been given to dietary antioxidants, especially polyphenols. Several peptides derived from protein molecules have also been found to show antioxidant capacity along with other biological properties and thus there is an increasing interest in these compounds as health promoters. This review summarizes and discusses the main sources of antioxidative peptides with focus on food-derived peptides (animal, plant and marine sources), methods of preparation, antioxidant capacity evaluation as well as their proposed mechanisms of action. A discussion of the potential health effects and comments on the different applications for these antioxidants and their potential research interest are also subject of this review.
- Maintaining optimal atmosphere conditions for fruits and vegetables throughout the postharvest handling chainPublication . Brech, J. K.; Chau, K. V.; Fonseca, S. C.; Oliveira, F. A. R.; Silva, F. M.; Nunes, M. C. N.; Bender, R. J.Optimal controlled and modified atmospheres (CA and MA) for fresh produce vary according to the specie, its maturity or ripeness stage, the temperature, and the duration of exposure. However, individual lots of produce are typically handled for different times and at different temperatures during storage, transportation, and retail display. In this paper, we review some of our previous work showing the potential for using different atmospheres for mangoes (Mangifera indica L.) and strawberries (Fragaria×ananassa Duchesne) depending on the anticipated storage length and temperature. Since it would be desirable, especially for produce transported over extended distances, as in marine transport, to maintain optimal atmosphere conditions throughout the postharvest handling chain, we also describe our procedure for designing a combination CA/MAP system that involves first designing the MAP for a particular commodity that will produce an optimal atmosphere for retail display conditions, then selecting a CA that will interact with the MAP to produce the optimal atmosphere within the packages during transportation at a lower temperature. An example of the design procedure is given from our work with fresh-cut kale (Brassica oleracea var. acephala DC.). Another example of this proposed MAP/CA system deals with its application to mixed load transportation of strawberries and snap beans (Phaseolus vulgaris L.).
