Microbiological and physico-chemical changes in lotus seeds as influenced by
ultraviolet radiation
Lotus seeds are sensitively perishable and browning. However, few publications have
emphasised on the application of UV-C treatment. The purpose of this work was to assess
the potential effect of UV-C irradiation on the physico-chemical and microbiological
quality of lotus seeds during storage at 4℃ for 8 days. The UV-C exposure times of 5
mins and 10 mins were evaluated. The results showed that the total viable count of 10
mins-UV-C treated lotus seeds met the standard quality of Thai Industrial Standards
Institute (TISI) crispy lotus seeds (TCPS 490-2547) (≤ 3 log CFU/g) although the yeast
and mould of all treatments were not affected by UV-C radiation (> 1 log CFU/g).
Moreover, the reduction level of browning degree was not affected by UV-C, whereas the
accumulation of phenolic content and the delay of product softening were found in the UV
-C treated sample for 10 mins when compared with the control treatment. Consequently,
the UV-C treated for 10 mins could be used as a promising approach to control the growth
of total bacterial count in lotus seed product during storage at 4℃.
