The toxicity of microorganisms such as aflatoxins found in various varieties of food that are currently widely consumed in Peru as in the world. Many of the foods contaminated with aflatoxins cause diseases, one of the main ones being carcinogenicity. This study aimed to evaluate the effect of ozone/air and UV concentration on the remediation of aflatoxins in different cereals or grains for human consumption. This study reviews how a new reactor can be developed that degrade and detoxify into more aflatoxins, however, many studies have verified that the harmful effects of AFB1 can be greatly reduced by UV irradiation in the photodegradation reactor, and the reactor can be applied on a large scale in the detoxification of AFB1 of many kinds of cereal, as well as in sewage. Therefore, there has been a growth in the development of new biofilm-type and closed reactors to reduce the amount of this toxin in food. The creation of new bioreactors such as the fluidized bed one is very promising for the decontamination of aflatoxins in cereals and would be less dangerous for consumers.
El proceso de percepción sensorial de alimentos ha recuperado la atención de los tecnólogos e investigadores alimentarios, por eso el presente trabajo de investigación tuvo como objetivo evaluar ocho atributos: sabor chocolate, vainilla, crocante, dulce, amargo, cremosidad, blando y grasoso en cuatro marcas de galletas de chocolate: Casino Black, Oreo, Field y Rellenitas (GN); haciendo uso del método de Dominancia Temporal de Sensaciones para determinar las sensaciones dominantes en el tiempo y estudiar la evolución de las características sensoriales durante la degustación. Los panelistas fueron consumidores frecuentes de estas galletas de edades entre 18 a 50 años; de los cuales el 75% fueron varones. Luego de la recolección y ordenación de datos, se construyeron curvas de dominancia en función de la tasa de dominancia y con el trazado de una línea de chance y otra de significancia; nos permitió observar la secuencialidad de dominancia de cada atributo. Para establecer diferencias significativas entre los 4 tipos de galletas según las sensaciones percibidas como dominantes; se aplicó ANOVA Y MANOVA a las distintas muestras. Concluyendo que la galleta Oreo tuvo como atributos dominantes a la cremosidad, dulzura y chocolate en ese orden; la Rellenita al sabor chocolate, blando y grasoso; Casino Black cremosidad, crocancia y dulzura y en la galleta Field el sabor vainilla, amargo y blando.
