Conservation of crisp lettuce in different post-harvest storage conditions

ABSTRACT The objective of this work was to evaluate the post-harvest quality and the final storage time of the hydroponic crisp lettuce ‘Brida’, conditioned in different types of plastic packaging and environments. The statistical design was a completely randomized 3x2 factorial design, with 3 types of packages (control (without plastic packaging), perforated plastic packaging and closed plastic packaging) and 2 types of environments refrigerated (± 5 °C) and non-refrigerated (± 23 °C). Fresh leaf weight loss, relative SPAD content, total soluble solids content (TSS), pH, total titrat...
