Evaluation of shelf life of various carrot genotypes planted on three different highlands

Carrot contains quite high nutrition, especially carotenoids, which function as antioxidants. This research aimed to evaluate the shelf life of various candidates among carrot genotypes that will be released as varieties. The research was applied toward those candidates which had been planted on three different locations were Cipanas, Garut, and Lembang. The evaluation was run at Postharvest Laboratory of Indonesian Vegetable Research Institute (IVEGRI), Lembang from March until July 2016. Shelf life was tested throughout quantitative evaluation using a hedonic test which admitted 15 untrained panelists and quantitative evaluation using measurement equipment. Parameters observed on carrot sensorial properties were colors and textures. Quantitative evaluation (method using equipment) applied for texture and weight loss parameters. Subsequently, correlation analysis was used to find out the relation between variable x (qualitative) and variable y (quantitative). Statistical analysis was run by using PKBT STAT. The result showed an interaction between genotypes and different planting locations toward carrot shelf life. Independently, planting locations showed a significant effect on carrot shelf life. Meanwhile, different genotypes showed a non-significant effect in carrot shelf life. All genotypes showed a non-significant difference in carrot shelf life. However, genotype F showed the longest shelf life 3three days, whereas genotype C showed the shortest shelf life two days at room temperature in Lembang.
