| Abstract: | Developing cold
sweetening resistant processing varieties is one of the frontal areas of
research all over the world. In India,
first potato processing variety was released in the year 1998 and till 2005
three varieties have been developed. But, there is no information available
regarding sugar accumulation response of Indian varieties to low temperature
storage. Therefore, it is imperative to generate basic information on cold
sweetening development in Indian processing varieties for the use of potato
breeders. Development of cold-induced sweetening and its relation to phenolic
content of the tuber was studied in three Indian potato varieties viz., Kufri Chipsona-1, Kufri Chipsona-3
and Kufri Jyoti. The reducing sugars decreased in initial phase of storage,
followed by continuous increase to unacceptably higher levels after around two
weeks of storage. The increase in reducing sugar contents took place subsequent
to increase in sucrose content. The changes in phenol content were not in a
fixed trend. The degree or number of folds increase in reducing sugar content
was relatively less in Kufri Jyoti which contained highest phenol content among
the three varieties investigated. It is suggested that development of
processing varieties with higher anti-oxidant content and lower invertase activity
may provide better cold-induced sweetening resistance. |
