total ascorbic acid

Added ascorbic acid delayed the increase of reducing sugar, titratable acidity, viscosity and total microbial count, and also prevented browning with reduced PPO and SNI activities in fresh sugarcane juice during storage.

添加抗坏血酸延缓了还原糖含量，可滴定酸，粘度和菌落总数的增加，同时在贮藏过程中伴随着PPO和SNI活性的降低也抑制了甘蔗汁褐变。

Blood samples were drawn every hour during each course for determining plasma total ascorbic acid ( TAA), ratio of dehydroascorbic acid ( DHAA) to TAA ( DHAA/ TAA), vitamin E ( Vit E), malondialdehyde ( MDA) in both plasma and erythrocytes.

每小时取血标本测定血浆总抗坏血酸（TAA）、脱氢型抗坏血酸/总抗坏血酸（DHAA/TAA）、维生素E（Vit E）、血浆与红细胞丙二醛（MDA）。
