Other claims from this paper (18)
- Intervention effect Spinach stored at room temperature lost about 56% fresh weight after 3 days.
- Intervention effect Spinach stored at 4C lost 20% fresh weight after 7 days, compared with room temperature storage.
- Intervention effect Spinach packaged in PE film and stored at room temperature lost 2.5% fresh weight after 3 days.
- Intervention effect Spinach stored at 4C with PE film packaging lost only 1.5% fresh weight.
- Observation At harvest sucrose was the highest soluble sugar, above glucose and fructose.
- Observation Glucose content at harvest was 1.9 mg/g FW.
- Observation Fructose content at harvest was 1.7 mg/g FW.
- Intervention effect Soluble sugars decreased rapidly during storage.
- Intervention effect Sucrose content after three days at 4C was higher in 0.03mm PE film packaging than in control.
- Intervention effect Sucrose content after three days at 4C was higher in 0.05mm PE film packaging than in control.
- Observation Ascorbic acid content decreased to 20 μg/g FW after 3 days of storage.
- Intervention effect PE film (0.03mm) packaging retained the initial ascorbic acid content at harvest.
- Observation Chlorophyll content at harvest was 400 g/g FW and slowly decreased during storage.
- Intervention effect PE film (0.05mm) packaging prevented chlorophyll decline during storage.
- Observation Non-packaged summer spinach at room temperature had a shelf life of not more than 3 days.
- Intervention effect Spinach packaged with 0.03mm PE film at room temperature maintained its quality for 3 days.
- Observation Summer spinach stored at 4C with 0.03mm and 0.05mm PE film packaging had a shelf life of about 7 days.
- Recommendation Low temperature (4C) storage combined with 0.05mm and especially 0.03mm PE film packaging is recommended to maintain quality of summer spinach after harvest.
