The study examined the content of reducing sugars in
various varieties of potato, beetroot, turnip and pumpkin most commonly
grown in Estonia. This study aimed to determine the varieties of
vegetables with the lowest levels of reducing sugars after harvesting and
after storage at two different temperatures (3 and 8 C). In the present
study it was found that the potato variety with the lowest content of
reducing sugars after harvesting and after six months of storage was potato
variety 'Birgit' with 0.19 g 100 g–1after harvesting, 0.98 g 100 g–1 after
storage at 3 C and 0.38 g 100 g–1 after storage at 8 C, respectively. All
three varieties of the beetroot, after harvest, contained a similar amount of
reducing sugars. After six months of storage, the lowest content of
reducing sugars was determined for variety 'Boro' with 1.22 g 100 g–1 at
3 C and 0.96 g 100 g–1 at 8 C, respectively. The lowest average
concentrations of reducing sugars from turnips were after harvest in the
variety 'Kohalik sinine' with 3.38 g 100 g–1. Also after storage, the same
variety had the lowest content of reducing sugars with 8.36 g 100 g–1 at
3 C and 3.76 g 100 g–1 at 8 C, respectively. From the pumpkin varieties,
the lowest reducing sugars contents were determined for variety 'Gold
Medal' with 2.64 g 100 g–1after harvesting, 2.40 g 100 g–1 after storage at
3 C and 1.90 g 100 g–1 after storage at 8 C. It can be concluded that all
studied vegetables stored at 3 °C contained higher amounts of reducing
sugars than those stored at 8 °C.
