Suitability of donata and BRS F 132 cultivar for the potato processing industry

Abstract

Changes in the population's eating habits have expanded the French fries market. However, the need for refrigerated storage to supply sprouts and maintain a constant supply to the industry has led to a reduced number of cultivars suitable for processing due to the accumulation of sugars and browning after frying. Because of this, the objective of this study was to evaluate the suitability of the Donata and BRS F132 cultivars for use in the pre-fried potato processing industry. The tubers were stored at 6 and 8 °C for up to 180 days and the analysis of sprouting, total soluble sugar (TSS), reducing sugar (RS), non-reducing sugar (NRS), post-frying color by scale visual color used by the industry and L* and b* parameters. The sprouting was higher at 8 °C and in the BRS F 132 cultivar. The sugar content was high in both cultivars, however, the color remained adequate. It is concluded that the Donata and BRS F132 cultivars are suitable for the potato processing industry, and Donata presented better quality parameters. Conditioning at 8 °C is recommended in both cultivars that maintained the quality for 180 days.

Differential response of potato cultivars intended for the processing industry

“…In a study with the Asterix, Corsica, Edison, Lionheart, and Markies cultivars, the sticks showed adequate color with L* above 45 and b* greater than 40 (Pereira et al, 2020a). In the genotypes Alibaba, Arsenal, Antartica, and Babylon, values of L* above 49.32 and b* greater than 48.3 were considered adequate (Pereira et al, 2020b), while in the cultivars Donato and BRS F 132, L* was above 55.8 and b* was greater than 44.5 (Pereira et al, 2022).…”

Bicentenaria, un nuevo cultivar de papa para procesamiento en el Perú: perspectivas desde la mejora genética

“…Asimismo, en cuanto al análisis colorimétrico de la prueba HunterLab, se observan en Bicentenaria valores similares a las variedades comerciales para fritura. Según la escala de colores y los parámetros establecidos se sugiere que los bastones con un buen color para la industria cumplan con un valor 'L' por encima de 55,8 (Pereira et al 2021).…”
