Pectic changes in pears during storage and ripening

  • Published:
Proceedings / Indian Academy of Sciences

Summary

A study has been made of the pectic changes in different varieties of pears under cold storage and periodical ripening as a part of the different chemical changes taking place in the fruit under such conditions. The nature of pectic changes could be summarised as follows :

  1. 1.

    The amounts of both protopectin and total pectin increased during storage in all the three varieties.

  2. 2.

    Anjou pears contained more total and protopectin than the other two varieties.

  3. 3.

    The data indicate a possibility of the synthesis of protopectin during storage.
