Moench / ญาวดี ศรีเมฆ = Relationships between pod characteristics, quality changes, and use of various plastic films on storage of okra Abelmoschus esculentus (L.) Moench pods / Yawadee Srimake
Anatomical studies of pods from three different okra lines, ‘Hit 9701,’ Timfood Company’s line, and a native line, showed that numbers of stomata and trichome per unit area or weight, and pericarp cuticular thickness were not statistically different among the lines. Postharvest storage studies of pods’ overall appearance were carried out in 4 different plastic bags; namely, high-density polyethylene (HDPE), low-density polyethylene (LDPE), OPP20/DL/L-LDPE50 (OPP), NY15/PE20/L-LDPE75 (NY), at 2 different temperatures: 10 and 14 ℃. Appropriate storage period and temperature of pods kept in various plastic bags were as follows: HDPE, 12 days, 10 and 14 ℃; LDPE, 12 days, 10 ℃; and OPP, 9 days, 10 ℃. All pods kept in plastic bags exhibited significantly less change in their size, weight, and water content than those of the control. Vitamin C content decreased significantly in 3 days, with that in bagged pods decreased at a slower rate. Carbon dioxide content in the bags increased throughout the storage period, with that in HDPE bags had the least amount and lowest increase rate. No significant differences in pod firmness and contents of total soluble solids, fiber, and pectin were observed.
