Prediction Models to Control Aging Time in Red Wine

Molecules 2019, 24(5), 826


A combination of physical-chemical analysis has been used to monitor the aging of red wines from D.O. Toro (Spain). The changes in the chemical composition of wines that occur over the aging time can be used to distinguish between wine samples collected after one, four, seven and ten months of aging. Different computational models were used to develop a good authenticity tool to certify wines. In this research, different models have been developed: Artificial Neural Network models (ANNs), Support Vector Machine (SVM) and Random Forest (RF) models. The results obtained for the ANN model developed with sigmoidal function in the output neuron and the RF model permit us to determine the aging time, with an average absolute percentage deviation below 1%, so it can be concluded that these two models have demonstrated their capacity to predict the age of wine.

Histolocalization of aldehyde accumulation in citral-treated Arabidopsis thaliana roots

Allelopathy Journal 37:71-76 · 2016


Growth and development of Arabidopsis thaliana seedlings treated with the essential oil component citral have been severely affected. We analyzed whether citral can enter and accumulate into the roots and we found that it interferes with the plant metabolism accumulating mainly in the differentiation zone. Besides, the distribution of stained zones varied with the experimental time.
