    Uso de cultivos andinos y cáscaras de huevo en el desarrollo de crema pastelera
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Maestría en Ciencia de los Alimentos, 2023-01) Pérez Pérez, Francisco Renato; Arancibia Soria, Mirari Yosune
    Trends in the consumption of healthy and natural foods have been increasing in recent years to minimize the incidence of chronic diseases caused by poor diet and lifestyle, so this research seeks that through the use of crops Andean underutilized products such as achira, oca and sweet potato (rich in nutrients and bioactive compounds), develop a pastry cream (very coveted in the confectionery and pastry industry) with added value, fortified with calcium from eggshells, bioavailable calcium , which is generally sent to municipal dumps as waste from the food industry, thus helping to minimize environmental impact and providing new alternatives for the use of Andean crops in the development of food products. In the research work, 4 prototypes of pastry creams were developed (C, CC, CY and CCY) that were evaluated by proximal analysis, APT, rheological properties, color measurement, stability, and sensory analysis. Investigation results indicated that eggshell powder significantly increased ash content without compromising rheological properties, weak gel characteristics, and sensory properties. The APT showed that the eggshell in the pastry cream slightly decreases the firmness and improves the elasticity, while the microbiological stability was maintained for 16 days thanks mainly to the heat treatment given to the pastry cream. According to the sensory analysis, it was concluded that the CC pastry cream prototype is the one that received the best score in the level of acceptability. The product developed could be an alternative to improve the intake of calcium and antioxidants from organic sources, and an innovative product with a great health and economic impact.
