ROMERO TEJEDA, María de la Luz et al. Postharvest quality changes of salvia (Salvia officinalis) stored under cold-storage conditions. Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2015, vol.47, n.2, pp.53-69. ISSN 1853-8665.

The aim of this study was to evaluate the effect of low temperatures on the postharvest quality of sage (Salvia officinalis L.). For this, the plants were stored at 0° to 6°C with compared to 23 ± 2°C (control) and packed in polyethylene bags, low density for 21 days. During this period were evaluated every three days: respiration rate (TR), production of ethylene (PE), weight loss (WL), total soluble solids (TSS), titratable acidity (TA), the total chlorophyll (CLT), color (*L, *C, °h) and vitamin C (VtC). Additionally, through a sensory evaluation: visual appearance, color scale, yellowing, leaf abscission and decay. The use of cooling (0° to 6°C) maintained the TR and PE values were 15.4 to 22.9 mL CO₂·kg-1 · h-1 and 0.06 to 0.46mL ethylene · kg-1 · h-1, respectively. The use of cooling diminished WL up to 40% sage. The CT and CL were stored for up to 15 days to 6°C. The VtC gradually decreased, but this decrease were more evident in the treatment at 23°C. The best treatment was 0°C, since, allowed prolong the quality of sage up to 12 days, contrary to the treatments to 6° and 23°C where quality only maintained for up to 9 and 6 days, respectively.
