Abstract
Mona Ibrahim Abd El-Rehim: Postharvest Physiology of some Vegetable Crops. Unpublished Ph.D. Thesis, Department of Horticulture, Faculty of Agriculture, Ain Shams University, 2015.
Baby pea (Pisum sativum L.) shoots and baby spinach (Spinacia oleracea L.) leaves as a new ready to eat baby leaf vegetable sprouts has a little information available about it, and since it is a fresh herb it have very short storage period after harvest. In this context we determined the effects of different passive modified atmosphere packaging applications for prolonging the shelf life of baby - pea shoots and baby spinach leaves. For baby pea shoot experiment, the performances of modified atmosphere packaging based on low density polyethylene (LDPE) film with different perforations (zero, 4 and 8 perforations/package) and different package sizes (size 1 25 × 20 cm and size 2 30 × 20 cm) was examined at different storage temperatures (0°C and 5°C) with 90-95% RH for 4, 8, 12, 16 and 20 days during storage.
As for baby spinach leaf experiment, the performances of modified atmosphere packaging based on low density polyethylene (LDPE) film or smart film in different package sizes (size 1 25 × 20 cm and size 2 30 × 20 cm) was examined at different storage temperatures (0-1°C and 4-5°C) with 90-95% RH for 4, 8, 12, 16 and 20 days during storage.
Some quality parameters, such as visual quality (graded to scale), decay, and off-odor, were evaluated. Vitamin C, carotenoid content, chlorophyll reading, dry matter, protein and fiber were also analyzed. In addition, the atmosphere composition inside the packages was measured at each observation.
Our findings suggest that baby pea shoots packaged in LDPE film bags stored at 0ºC in both package sizes (size 1 and 2) without perforations or with 4 and 8 perforations maintained good quality and shelf life throughout 12 days. Baby pea shoots stored at 5ºC in both package sizes (size 1 ”25 cm length × 20 cm width” and size 2 ”30 cm length × 20 cm width”) without perforations or with 4 and 8 perforations maintained good quality and shelf life throughout 8 days.
Baby spinach leaves could be stored for 16 days with good quality at 0ºC and 95% RH in bags prepared from LDPE film and for 12 days in smart film in both package sizes (size 1 and size 2). Also, it could be stored for 8 days at 5ºC in the same package materials (LDPE film and smart film) and sizes.
