Comparative study of the loss of vitamin C in chalarina (Casimiroa edulis) by four methods of dehydration
Descripción del Articulo
The aim of this study was to compare the loss of chalarina vitamin C after applying four methods of dehydration: vacuum osmotic dehydration combined with convective drying, convective drying, osmotic dehydration combined with vacuum freeze-drying, and freeze-drying. The fresh chalarina was fitted in...

Comparative study of the loss of vitamin C in chalarina (Casimiroa edulis) by four methods of dehydrationEstudio comparativo de la pérdida de vitamina C en chalarina (Casimiroa edulis) por cuatro métodos de deshidrataciónCastañeda, JudithArteaga, HubertSiche, RaúlRodriguez, GilbertChalarinavitamin Cosmotic dehydrationfreeze-dryingChalarinavitamina Cdeshidratación osmóticaliofilizaciónThe aim of this study was to compare the loss of chalarina vitamin C after applying four methods of dehydration: vacuum osmotic dehydration combined with convective drying, convective drying, osmotic dehydration combined with vacuum freeze-drying, and freeze-drying. The fresh chalarina was fitted into cubes of 1 cm; we determined the vitamin C content and other chemical properties of the pulp. The powders were characterized: vitamin C, moisture content, aw, density, angle of flow and compressibility. Fresh chalarina pulp has a vitamin C content of 29.75 mg/100g. Osmotic dehydration and vacuum reduced to 15.75 mg/100g this content; combined with convective drying is reached 9.31 mg/100g; if combined with freeze-drying is obtained 14.98 mg/100g. Applying convective drying was obtained only 7.05 mg of vitaminaC/100g chalarina powder, while by applying only freeze-drying was obtained 23.63 mg/100g. We conclude that the powder obtained by vacuum osmotic dehydration - convective drying has better physical and chemical characteristics of powders obtained with other methods of dehydration.El objetivo de este estudio fue comparar la pérdida de vitamina C de la chalarina después de aplicar cuatro métodos de deshidratación: deshidratación osmótica a vacío combinada con secado convectivo, secado convectivo, deshidratación osmótica a vacío combinada con liofilización, y liofilización. La chalarina fresca fue acondicionada en forma de cubos de 1 cm de arista; se determinó el contenido de vitamina C y otras propiedades químicas de la pulpa. Los polvos obtenidos fueron caracterizados: contenido de vitamina C, contenido de humedad, aw, densidad, ángulo de fluencia y compresibilidad. La pulpa de chalarina fresca presentó un contenido de vitamina C de 29.75 mg/100g. La deshidratación osmótica a vacío redujo este contenido hasta 15.75 mg/100g, que combinado con secado convectivo se llega a 9.31 mg/100g; en tanto, combinado con liofilización se obtuvo 14.98 mg/100g. Aplicando sólo secado convectivo se obtuvo 7.05 mg de vitaminaC/100g de polvo de chalarina, mientras que aplicando sólo liofilización se obtuvo 23.63 mg/100g. Se concluye que el polvo obtenido por deshidratación osmótica a vacío - secado convectivo presenta mejores características fisicoquímicas que los polvos obtenidos con los otros métodos de deshidratación.Universidad Nacional de Trujillo2010-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/1810.17268/sci.agropecu.2010.01.07Scientia Agropecuaria; Vol. 1 No. 1 (2010): January - March; 75-80Scientia Agropecuaria; Vol. 1 Núm. 1 (2010): Enero - Marzo; 75-802306-67412077-9917reponame:Revista UNITRU - Scientia Agropecuariainstname:Universidad Nacional de Trujilloinstacron:UNITRUspahttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/18/33Derechos de autor 2010 Scientia Agropecuariainfo:eu-repo/semantics/openAccess2021-06-01T15:35:14Zmail@mail.com - |
