Crystallization and Plasticity of Industrial Margarine for Bakery
The margarine is a raw material used in the preparation of bread; a product consumed daily by around 13 million of people in Ecuador.

Considering that the bread’s quality depends on margarine, and this characteristic is a consequence of the presence of ß’-crystals, which give the margarine an homogeneous consistence, shine and color, we investigated the influence of the standard production parameters on the margarine’s characteristics. Flow, emulsion temperature, cooling temperature and crystallization speed were tested, and the structural differences were analyzed using Polarized Light Microscopy, rheological analysis, Differential Scanning Calorimetry (DSC) and sensorial evaluation. The optimal parameters found for the formation of ß’- crystals were: flow 1590 - 1690 kg/h, cooling temperature 14 – 16 °C and crystallization speed 220 - 240 rmp. The emulsion temperature was a parameter that no influenced the formation of crystals.La margarina es una de las materias primas utilizadas en la elaboración del pan, producto de consumo diario para alrededor de 13 millones de habitantes del Ecuador. Tomando en cuenta que la calidad del pan depende de la margarina, y ésta a su vez de las estructuras cristalinas ß’ que proporcionan a la margarina consistencia homogénea, brillo y color, se estudió la influencia de los parámetros de producción estándar en las características de la margarina. Once condiciones de producción con cuatro variables: caudal, temperatura de emulsión, temperatura de enfriamiento y velocidad de cristalización, se investigaron y las diferencias estructurales se analizaron utilizando microscopia de luz polarizada, análisis reológico, análisis calorimétrico diferencial y evaluaciónsensorial. Los parámetros óptimos de producción que influyen directamente en la formación de estructuras cristalinas ß’, fueron: temperatura de enfriamiento de 14°C a 16°C, caudal de emulsión de 1590 Kg/h a 1690 Kg/h, velocidad de cristalización de 220 a 240 rpm. La temperatura de emulsión fue un parámetro que no influyó en la formación de los cristales.Universidad Central del Ecuador2011-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistadigital.uce.edu.ec/index.php/QUIMICA/article/view/56910.29166/quimica.v2i1.569Química Central; Vol. 2 Núm. 1 (2011): Química Central; 39-472477-91211390-5562reponame:Revista Química centralinstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/QUIMICA/article/view/569/556Derechos de autor 2011 Química Centralinfo:eu-repo/semantics/openAccess2019-09-25T17:51:19Zoai:revistadigital.uce.edu.ec:article/569Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/..Ecuador.2477-91211390-5562opendoar:02024-03-31T15:57:55.319053Revista Química central - Universidad Central del Ecuadortrue |

Flow, emulsion temperature, cooling temperature and crystallization speed were tested, and the structural differences were analyzed using Polarized Light Microscopy, rheological analysis, Differential Scanning Calorimetry (DSC) and sensorial evaluation. The optimal parameters found for the formation of ß’- crystals were: flow 1590 - 1690 kg/h, cooling temperature 14 – 16 °C and crystallization speed 220 - 240 rmp. The emulsion temperature was a parameter that no influenced the formation of crystals. |
