| Ingestion of vegetables containing heavy metals is one of the main ways in which these elements enter the human body. Once entered, heavy metals are deposited in bone and fat tissues, overlapping noble minerals. Slowly released into the body, heavy metals can cause an array of diseases. This study aimed to investigate the concentrations of cadmium, nickel, lead, cobalt and chromium in the most frequently consumed foodstuff in the São Paulo State, Brazil and to compare the heavy metal contents with the permissible limits established by the Brazilian legislation. A value of intake of heavy metals in human diets was also calculated to estimate the risk to human health. Vegetable samples were collected at the São Paulo General Warehousing and Centers Company,... |

| ABSTRACT Carotenoids are incorporated into the diet of laying hens in order to modify the yolk color. A natural source of carotenoids in tropical countries is annatto, which could be used in the diets of hens. This study aimed to evaluate the addition of natural (annatto) and synthetic carotenoids to the diet of laying hens (commercial and alternative) and their effects on yolk color and consumer sensory perception of fresh and stored eggs obtained from two different preparations (boiled and fried). Physicochemical analysis of proximate composition, thiobarbituric acid reactive substances (TBARS), emulsion activity and instrumental color were performed. Cooking caused significant alterations to the moisture in the preparations and this may have directly... |

| O ovo é um alimento considerado nutricionalmente completo, e contém quantidade significativa de nutrientes. Para os consumidores, a qualidade deste alimento está relacionada com o prazo de validade do produto e com as características sensoriais, como cor da gema e da casca. Poucos estudos foram efetuados no Brasil sobre a utilização de agentes pigmentantes e seus efeitos sobre a coloração das gemas e proporção e qualidade química dos componentes do ovo. Com base nisso, objetivou-se com este trabalho relacionar diferentes dietas com cor, quantidade de betacaroteno e teor colesterol das gemas dos ovos. Foram coletados ovos de poedeiras que receberam 4 diferentes tipos de ração. A cor foi medida em colorímetro Minolta, o beta-caroteno separado em coluna e... |
