Evaluation of protein enrichment process pineapple residue
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
Pineapple processing for industrial purposes produces a large volume of waste, which have energy potential and can be leveraged to generate value-added products. The objective of this work was to study the nutritional enrichment process pineapple residues (bark and crown), with the use of the yeast Saccharomyces cerevisiae, through the process of fermentation semisolid, evaluating the initial concentration of yeast and fermentation temperature on the protein content. Fermentation was carried out in trays, bioreactors with air circulation containing 1000 g of residue, with 4.65% of yeast, the temperature of 38 °C, for a period of 48 h where seven samples were taken every 8 h and taken the greenhouse with a temperature of 55 °C, being the end of fermentation pounded into knife mill. Semisolid fermentation using the pineapple residue showed that the microorganism grew and increased the protein content of the residue in function of time in which the same remained in controlled temperature, showing up for animal feed.
