Antioxidative Compounds from Fermented Olive Mixed in Fish Feedstuffs
Author(s): Muhammad Hayat*
Bioactive compounds like enzymes and antioxidants have been added to the feed to ensure its long-term viability and increase its nutritional value. However, feed additives may lose their efficacy and activity during the pelleting and storage processes. The stability of functional activity in feeds enriched with antioxidants, cellulases, and other bioactive extracts was the primary focus of this study. This bioactive extract (FBE) was produced by Aspergillus ibericus through solidstate fermentation of byproducts from olive mills and wineries. With or without lyophilized FBE (0.26 percent w/w) as a supplement, two isolipidic and isoproteic diets were developed. Both diets were kept at room temperature (RT), or 4 °C, for four months. The results indicated that feed stored at 4 °C was more stable for cellulase than for xylanase. The half-lives of cellulase and xylanase were approx.. View More»
