Human interference in production systems becomes feasible through the use of specific devices that, among other functions, allow monitoring, control and optimization processes. One drawbacks encountered sugar ethanol industry is lack instruments for measurement °Brix concentration sugarcane that are low-cost non-destructive. The monitoring cane necessary to identify appropriate time harvesting ...

In this experiment the effect of edible coating (apricot gum) was used to extend the shelf life of apple slices. The edible coating was applied at different concentrations i.e. 0.5, 1, 2 and 3%. Physicochemical characteristics of edible coated apple slices were analyzed at different time intervals. The analysis was carried out for 12 days with an interval of 4 days. Results showed that the trea...

Permittivities from 10 to 4500 MHz at 24◦C were measured on pulp and juice of watermelons of different maturities with an open-ended coaxial-line probe and network analyzer. The dielectric constant of both materials decreased monotonically with increasing frequency and loss factor had a minimum at about 1000 MHz. Moreover, the pulp and juice had very similar loss factor values at each frequency...

Uninformative biological variability elimination methods were studied in the near-infrared calibration model for predicting the soluble solids content of apples. Four different preprocessing methods, namely, Savitzky-Golay smoothing, multiplicative scatter correction, standard normal variate, and mean normalization, as well as their combinations were conducted on raw Fourier transform near-infr...

The objectives of this study were to determine the importance of simple and complex components of the interaction genotype × environment and to evaluate the adaptability and stability of Gália melon hybrids. Nine hybrids were tested in twelve environments of Rio Grande Norte State from 2000 to 2001. The experiments were carried out in a randomized complete block design with three replications. ...
