J. Makhlouf et al., SOME NUTRITIONAL CHARACTERISTICS OF BEANS, SWEET CORN AND PEAS (RAW, CANNED AND FROZEN) PRODUCED IN THE PROVINCE OF QUEBEC, Food research international, 28(3), 1995, pp. 253-259
A three-year study was conducted to assess some nutrient contents of b
eans, sweet corn and peas (raw, canned and frozen) produced by four pr
ocessing plants in the province of Quebec. Nutritional analysis were c
onducted on vitamin C, riboflavin, thiamin, minerals (Ca, Mg, K, Na, F
e) and fibers (solubles, insolubles and total). Results showed that th
e nutrient contents of raw and processed vegetables were quite differe
nt from those reported in the USDA Handbook no. 8-11. The differences
were mainly due to vitamin C and mineral contents. Results also showed
that raw vegetables when boiled under optimal conditions have nutrien
t contents similar to frozen vegetables and superior to canned vegetab
les. Among minerals Na was the most variable, probably due to variatio
n in recipes from one processing plant to another. Na contents of cann
ed vegetables were lower than the average values in the USDA tables. T
he study also provides new information on nutritive values of canned c
orn-on-the-cob which was not listed in USDA tables, and generates new
nutrient data such as fibers (solubles, insolubles and total contents)
to update the present food composition tables.
