摘要：

Perforation-mediated modified atmosphere packaging of soft kale (Brassica oleracea L. convar. acephala (DC) Alef. var. sabellica L.) was investigated to maintain freshness at 10 degrees C for 12 d. Kale was sealed in micro-perforated pouches with different oxygen transmission rates (OTRs: mL m(-2) d(-1) atm(-1)) at 1.66 x 10(6), 3.0 x 10(3) or 64. Headspace atmospheres (O-2/CO2) of pouches at OTR 1.66 x 10(6), 3.0 x 10(3) and 64 were 21 %/0 % (normoxia), 1.9 similar to 7.4 %/8.5 similar to 9.6 % (modified atmosphere) and 0 %/> 20 % (hypoxia), respectively. Hue angles (degree of green color) of leaves in the OTR 3.0 x 10(3) and 64 pouches were significantly higher than that in the OTR 1.66 x 10(6) pouch. However, carotenoid and ascorbic acid concentrations in the leaf in the OTR 3.0 x 10(3) pouch was significantly higher than that in the OTR 64 pouch. The modified atmosphere created in the OTR 3.0 x 10(3) pouch was suitable for maintaining external (green color) and internal (bioactive compounds) qualities of soft kale.
