RODRIGUEZ-FELIX, Armida  e  FORTIZ-HERNANDEZ, Judith. Quality fresh nopal cut packaging plastic layers during low temperature storage. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.4, pp.793-807. ISSN 2007-0934.

In this work the quality of fresh cut nopal (NVFC) packed in three plastic layers during low temperature storage was evaluated. Cladodes cultivar COPENA F-1 were cladodes, cut and packaged in bags of PEBD (control), polysweat Bolco® and Cryovac® PD960, subsequently stored at 1 and 5 °C for 20 days. The initial color of NVFC packaged in all three layers showed values of brightness or clarity (L*) of 52.2 to 55.3, an angle of pitch (AT) between 123 and 124°, and a chroma or color saturation of 22.1 to 24.2, this represents a dull green color. Overall, the green off the packaging NVFC evaluated the three layers was maintained during the 20 days of storage at 1 and 5 °C. Firmness, initial pH and titratable acidity of NVFC were 3.6 N, 4.3 and 0.75% respectively and showed no significant changes affecting the quality of packaging NVFC three layers evaluated during storage at 1 and 5 °C. Storage at 1 °C inhibited browning and mucilage secretion NVFC evaluated in all three layers. The NVFC packaging bags polysweat Bolco® showed the greatest beneficial effect in reducing darkening and secretion of mucilage during storage at 1 and 5 °C; this effect being greater than 1 °C.
