Summary

  1. 1.

    Ascorbic acid in neera was estimated by titration against 2:6 dichlorophenol indophenol. The samples showed a marked variation in ascorbic acid content.

     
  2. 2.

    The loss of ascorbic acid in neera was very small on storage at 37° C. for 72 hours.

     
  3. 3.

    A high concentration of sulfhydryl compounds was observed in neera.

     
  4. 4.

    Presence of dehydro-ascorbic acid reductase has been shown in neera.

     
  5. 5.

    The stability of ascorbic acid in neera has been attributed to the presence of (i) sulphahydryl compounds and (ii) dehydro-ascorbic acid reductase.
