A method of preparing a refined zein-enriched protein hydrolysate composition and/or a refined zein-depleted protein hydrolysate composition comprising enzymatically hydrolyzing a refined zein-enriched protein composition and/or a refined zein-depleted protein composition that have been separated from a refined, destarched corn gluten meal. The refined zein-enriched protein hydrolysate composition has a protein solubility of from about 15% to about 20% at a pH selected from the group consisting of pH 3.4, pH 7.0, and of both pH 3.4 and pH 7.0. The refined zein-depleted protein hydrolysate composition has a protein solubility of from about 20% to about 35% at a pH selected from the group consisting of pH 3.4, pH 7.0, and of both pH 3.4 and pH 7.0. Alternatively, the refined zein-enriched protein composition and/or the refined zein-depleted protein composition have been separated from a corn protein isolate as described herein. Compositions are also provided. Un método para preparar una composición de hidrolizado de proteína enriquecida con zeína refinada y/o una composición de hidrolizado de proteína reducida en zeína refinada que comprende hidrolizar enzimáticamente una composición de proteína enriquecida con zeína refinada y/o una composición de proteína reducida en zeína refinada que se han separado de una harina de gluten de maíz sin almidón refinada. La composición de hidrolizado de proteína enriquecida con zeína refinada tiene una solubilidad de proteína de aproximadamente 15 % a aproximadamente 20 % a un pH seleccionado del grupo que consiste en pH 3.4, pH 7.0, y en ambos pH 3.4 y pH 7.0. La composición de hidrolizado de proteína reducida en zeína refinada tiene una solubilidad de proteína de aproximadamente 20 % a aproximadamente 35 % a un pH seleccionado del grupo que consiste en pH 3.4, pH 7.0, y en ambos pH 3.4 y pH 7.0. Alternativamente, la composición de proteína enriquecida con zeína refinada y/o la composición de proteína reducida en zeína refinada se han separado de un aislado de proteína de maíz como se describe en la presente descripción. También se proporcionan composiciones.
