Abstract: Taking Kyoho grapes as the experimental material, the grapes were treated with houttuynia cordata extract at concentrations of 0.5,1.0 and 2.0 mg/mL respectively. The effect of houttuynia cordata extract on the preservation of Kyoho grapes was assessed by changes in indicators of the weight loss rate, vitamin C content, titratable acid content and soluble solid content. The results showed that houttuynia cordata extract treatment could effectively slow the decrease of water, vitamin C content, and titrate acid and soluble solid content during storage, which reduced the loss of nutritional value and prolonged the shelf life of grape.

Key words: Houttuynia cordata extract, grape, preservation effect
