Effect of Post Harvest Treatments on Tomato (Solanum lycopersicum) and its Remediation by Plant Extracts
Publication Date : 04/03/2017
Tomatoes are grown for its edible fruits, which can be consumed either fresh as a salad or after cooking as snacks. Tomatoes are a store house of antioxidants such as lycopene, ascorbic acid. A major problem with the storage and marketing of fresh tomatoes is their relatively fast deterioration in quality and short shelf life. Hence, different post-harvest methods are employed in reducing the losses and extending the shelf life. In this experimental set up tomato fruits were randomly selected. The vitamin C and lycopene content of healthy tomatoes was observed. The infected tomatoes were pin pricked and dipped in aqueous and ethanol Allium sativum extracts for one hour. The same treated tomatoes were analysed for vitamin C and lycopene content. Vitamin C and lycopene content of infected untreated (control) tomatoes was also observed. Results indicated that there was an increase in vitamin C and lycopene content of infected aqueous and ethanol (1 hour) A. sativum treated tomatoes as compared to untreated infected (control) tomatoes, though not to the level of vitamin C and lycopene contents, as obtained in healthy (control) tomatoes. Thus A. sativum extracts were beneficial in retarding loss of vitamin C and lycopene content in infected treated tomatoes.
