Abstract: The clarification effects of wheat gluten added into Chardonnay grape juice at 250,375,500 and 625 mg/L were investigated in this study.Result showed that the deposit weight of the grape juice is the biggest and its clarification effect is the best when the addition amount of wheat gluten is 500 mg/L.The chroma,titrated acid content and phenolic acid content of the grape juice all decrease but the protein content increases.Compared with bentonite and tannin-gelatin,wheat gluten is more suitable for the clarification of Chardonnay grape juice.

Key words: wheat gluten, clarification, Chardonnay, grape juice
