Sunflower (Heliantus annuus L.) meal is an important by-product as a source of vegetable protein and fiber for humans and animals; however, its nutritional value is notoriously dependent on processing technology. In this study, our aim was to evaluate a processing system based on micronization and air classification of the sunflower meal as a means of greater enrichment of the protein fraction and reduction of fiber content. We also evaluated the structural characteristics of the different meal fractions through scanning electron microscopy. This system was based on a series of sortings of micronized meal, with a progressive increase in the yield of a selected fraction. Air classification of sunflower size fractions (coarse and fine) was effective (P P P Keywords: air classification; calidad; clasificación neumática; girasol; micronización; micronization; quality; rendimiento; sunflower; yield Document Type: Research Article DOI: http://dx.doi.org/10.1080/19476337.2013.781681 Affiliations: 1: Section of Veterinary Science and Animal Production, Department of DETO, University of Bari “Aldo Moro”, 70010, Valenzano, Italy 2: SeparMicroSystem, via Manzoni 65, 25020, Flero, Brescia, Italy Publication date: November 1, 2013 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350){ shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function() { $(".shortdescription").hide(); $(".originaldescription").slideDown(); return false; }); }); Related content In this: publication By this: publisher By this author: Laudadio, V. ; Bastoni, E. ; Introna, M. ; Tufarelli, V.
