Abstract
Yacon (Polymnia sonchifolia Poepping & Endlicher), which contains fructo-oligosaccharide, is low calorie functional food. Yacon is efficacious against cholesterol, obesity, and diabetes. Yacon K-23 has antibacterial activity against Gram-positive (Listeria monocytogenes KCTC 3710 and Staphylococcus aureus KCTC 1927) and negative (Salmonella typhimurium KCTC 2514, Escherichia coli KCCM 11591, Proteus vulgaris KCTS 2512, and Pseudomonas aeruginosa KCCM 11803), Yacons A (water extract) and B (crushed juice) showed clear zone of 10mm, while Cassiae Semen, Acanthopanacis Cortex, Angelica gigas showed 7-10mm. Yacon jam showed good sensory attributes, suggesting it could be utilized as food ingredient. Hardness, adhesiveness, and strength of strawberry jam with or without aloe vera were higher than those of yacon jam with or without aloe vera.
