Alterações nuricionais em casca e polpa de cenoura decorrentes de diferentes métodos de cozimento

The aim of this study was to verify the carrot cooking most suitable method to minimize nutrient losses. Carrot peel slices were subjected to pre cooking tests that were initiated with 0.5 min of duration and then increased in 0.5 min successively. The carrot pieces texture was monitored during the pre tests so all would havethe same texture independent of the type of cooking. The degree of softennes was evaluated by pressuring the pieces between the toes. The carrot pulp and pell were subjected to four types of heat treatment (pressure, immersion, microwave, and steam), after that they were pounded with a food processor and stored at -18 ºC. The nutritional analyses were as follow: The evalu determination of proteins, lipids, fibers, sugars reducers, total of ascorbic acid content and minerals (iron, calcium, zinc, magnesium, potassium, phosphorus, and calcium). The analyses were accomplished with fresh carrot and after cooking with the different methods. The peel of the carrot presented as amounts of proteins, lipids, fibers percentages, sugars reducers, total and ascorbic acid content equivalent to the pulp. In addition, the minerals content was superior in the peel in relation to the pulp, presenting respective percentages of 38,10%, 95,12%, 47,04%, 58,88%, 70,27% and 21,27%. There were nutrient losses in relation to the raw vegetable, when the carrot pieces were submitted to the different cooking methods. The methods of steaming and microwave had lower nutritional losses.
