Technological parameters of agroindustrial concern of prickly-pear cactus (Opuntia spp.) in “Cristalina” and “Pelon Blanco” varieties

Abstract

Objective. To test and verify the main physical attributes of fresh cladodes of the prickly-pear cactus (nopal) Cristalina and Pelon Blanco varieties; and the flours obtained after they are dried and ground. Design/ Methodology/ Approach. Physical characteristics were determined using proven and reliable tests. Data shall serve to explore the potential of this material to be used in basic and complex processes; considering the varieties requierements for growth space and quality parameters for storage. Along with the interaction with processing devices and equipment for proper handling while manufacturing new products. Results. Physical characteristics of the two nopal varieties showed slight differences in the measured parameters, except length, width and electrical conductivity. Limitations/ Implications of the study. Researchers did not participate in the production of the evaluated Opuntia spp. varieties. Physical characteristics of the varieties were recorded at the time when the cladodes were separated from the plants. Findings/ Conclusions. With the procedure proposed, the mechanical transport of the cladodes into the facilities is improved. In addition, it generates less wear of the equipment, and reduces the costs of maintenance and handling. The quality of the flour from each variety was adequate to allow a safe storage
