“mora de Castilla” is a native shrub of the Andean tropics and can be found in Colombia, Ecuador, Mexico, and other countries of this region. In Colombia, this fruit is cultivated by small producers and is an important source of income and rural employment. “mora de Castilla” is in great demand for domestic consumption as well as for export because it can be consumed fresh or processed and because of its extraordinary organoleptic and nutritional attributes. Risaralda is one of the departments in which Rubus glaucus Benth. is cultivated; there, plants with and without prickles are widely distributed. Although some studies have been carried out on these cultivars, it is necessary to evaluate and compare some of their attributes as an approach to recognize potential uses in agribusiness. Therefore, a physicochemical characterization was performed, the vitamin C content was evaluated, the amount and profile of anthocyanins were determined, and the antioxidant capacity of fruits of “mora de Castilla” with and without prickles was analyzed. The physicochemical parameters evaluated were weight, pH, soluble solids and titratable acidity. The content of vitamin C was evaluated using the 2-nitroaniline spectrophotometric method, and anthocyanins were evaluated using 2 methods: spectrophotometry (pH differential) and chromatography (HPLC). Finally, the antioxidant capacity was determined using the FRAP and DPPH methods. Significant differences were found between the municipalities as well as between the materials with and without prickles with regard to antioxidant capacity and vitamin C and anthocyanin content, with the highest values for fruits grown in the municipality of Pereira, Risaralda. The results obtained indicate that “mora de Castilla” with and without prickles is a fruit of high quality and promise because of its high content of bioactive compounds (vitamin C and anthocyanins), its relevant function as an antioxidant and its valuable organoleptic attributes.

Thanks to its geographical and climatic advantages, Colombia has a historically strong fruit-growing tradition. To date, the basis of its food and economic development in a significant part of its territory is based on a wide range of fruits. One of the most important in the central and western regions of the country is the blackberry, which is rooted not only from the economic and food point of view but also culturally. For the departments of Casanare, Santander, and Cundinamarca, this fruit is one of the primary sources of income, rural employment, and food supply and income. However, small and medium farmers cultivate without access to technological production tools and with limited economic capacity. This process suffers from several problems that affect the whole plant, especially the fruit, which is strongly influenced by fungi, extreme ripening processes, or low temperatures. One of the main problems to be dealt with in its cultivation is the spread of pests, which are one of the causes of fruit rot. As a support strategy in producing this fruit, the development of an embedded system for visually diagnosing the fruit using a deep neural network is proposed. The article presents the training, tuning, and performance evaluation of this convolutional network to detect three possible fruit states, ripe, immature, and rotten, to facilitate the harvesting and marketing processes and reduce the impact on the healthy fruit and the quality of the final product. The model is built with a ResNet type network, which is trained with its dataset, which seeks to use images captured in their natural environment with as little manipulation as possible to reduce image analysis. This model achieves an accuracy of 70%, which indicates its high performance and validates its use in a stand-alone embedded system.
