S. Chalom et al., COMPOSITION OF SULFITED POTATOES - COMPARISION WITH FRESH AND FROZEN POTATOES, Plant foods for human nutrition, 47(2), 1995, pp. 133-138
The content in moisture, fat, protein, carbohydrate, fibre and vitamin
C was analyzed in three commercial types of potatoes: sulfited (treat
ed with E223), frozen potatoes (pre-fried) and fresh potatoes (not pro
cessed). The composition of sulfited potatoes does not usually appear
in food composition tables. Our results showed significant differences
in the content of carbohydrates and fibre between sulfited and fresh
potatoes. The content of vitamin C in sulfited potatoes, which is simi
lar to that of frozen potatoes, was shown to be approximately half of
that found in fresh potatoes.
