【Abstract】 Experiment results indicated that the extracting ratio of carrot juice was the highest after carrots were treated by the freezing and thawing method. The contents of soluble solids and carotene in extracted carrot juice were the highest when carrots were blanched for 21 min by steam. The weights of soluble solids and carotene drawn from per unit weight of carrots were the heaviest when carrots were blanched for 30 min by steam.更多还原
