Notes:
The ascorbic acid (vitamin C) and β-carotene (provitamin A) contents of ripe tomatoes harvested at different stages of ripeness or treated with supplementary ethylene were determined. Vitamin C activity in 100g ranged from 15-50% U.S. Recommended Daily Allowance (RDA) among cultivars. Vitamin C activity was not affected by stage of ripeness at harvest, but was slightly higher in a few cultivars treated with ethylene. The vitamin A activity in 100g ranged from 10-140% U.S. RDA among cultivars. Vitamin A activity was not affected by ethylene, but was slightly higher in ripe fruit that had been harvested ripe than those harvested mature-green. However, fruit harvested mature-green or breaker, the stages at which most fresh market tomatoes are harvested, did not differ in vitamin A activity for three of the four cultivars tested.
