Stability of ascorbic acid in neera from date palm (Phonix silvers tres)
- 11 Downloads
Ascorbic acid in neera was estimated by titration against 2:6 dichlorophenol indophenol. The samples showed a marked variation in ascorbic acid content.
The loss of ascorbic acid in neera was very small on storage at 37° C. for 72 hours.
A high concentration of sulfhydryl compounds was observed in neera.
Presence of dehydro-ascorbic acid reductase has been shown in neera.
The stability of ascorbic acid in neera has been attributed to the presence of (i) sulphahydryl compounds and (ii) dehydro-ascorbic acid reductase.
