Precursors such as vitamins -carotene and vitamins such as -tocopherol, as antioxidants, and classified as essential to human nutrition are found in food. Your daily intake prevents type of coronary disease, some cancers, poor-absorption syndrome of fat, genetic malformation, among others. Their determination to quickly and inexpensively is of interest to the academic and scientific community, especially for developing countries. Spectrophotometric methods were used to identify and quantify the presence of both antioxidants in the juice and in dried tomato tree, the latter obtained by lyophilization. The fruit of Andean origin, consumed especially in juice, fruit has been regarded as promising alternative crop for programs to eradicate illicit crops. Using the Student t statistic, significant differences were found, more than 90% of -tocopherol and 41% for the carotene (both with respect to the average). In addition, related variables: weight loss of the sample, freezing temperature and time by response surface, obtaining a second order equation that describes the process.
