The aim of the present work was to optimize the sensorial and technological features of ice cream. The experimental work was performed in two stages: 1) optimization of lactose enzymatic hydrolysis, and 2) optimization of the process and product. For the first stage a complete factorial design was developed, optimized using both response surface and the steepest ascent method. In the second stage a mixture design was performed, combining the process variables. The product with the best sensorial acceptance, high yield and low cost was selected. The acceptance of the product was developed by an untrained taster’s panel. As a main result the sensorial and technological features of the final product were improved, establishing the optimum parameters for its elaboration.

Introducción: El glaucoma es una neuropatía óptica progresiva que daña el nervio óptico y las fibras de la retina. Controlar la presión intraocular es clave para frenar su avance. En casos avanzados o resistentes al tratamiento, se recurre a la trabeculectomía. El tratamiento médico consiste en colirios hipotensores, usados solos o combinados según la gravedad. Sin embargo, la adherencia puede verse afectada por costos y comodidad. Comprender estos tratamientos mejora la calidad de vida y la salud ocular de los pacientes. Objetivos: Describir la eficacia de la trabeculectomía enfocado al mantenimiento de la visión y el impacto en la reducción del costo promedio mensual asociado al uso de gotas hipotensoras en pacientes con glaucoma sometidos a trabeculectomía en el Hospital Nacional Arzobispo Loayza. Materiales y Métodos: Estudio retrospectivo de cohorte en pacientes con gl...

ABSTRACT This research work is focused on reducing production costs, establishing hierarchical lines of quality control through the basic tools. For this, it is possible to identify the strategic, tactical and operational objectives that lead us to look for solution indicators. The aggregates S.A.C plant, when faced with increasingly strong competitive pressures, has the need to coordinate the activities of its functions in a coherent strategy that integrates each and every one of its functions perspectives. After an initial evaluation, it was observed that the plant does have the ISO 19001 certification which has not had a continuous sustainability during the processes, therefore the products were not compliant, which led to using other methods looking for alternatives to improve the products applying quality tools, so it focused as the first objective in analyzing the raw material and ...
