Abstract
Fruit of blueberry (Vaccinium corymbosum L.), precooled to 2°C, had 60–80% less decay than non-precooled berries when held for 24 hours at 21° following a 3-day simulated transit period at 10°. When precooled berries were held 48 hours at 21° following a 10-day simulated transit period at 2°, they had 37–46% less decay than non-precooled berries similarly handled.
Abstract
Sweet peppers from wholesale and retail markets and simulated consumer storage were analyzed for total ascorbic acid, riboflavin, and thiamine. Peppers from these tests contained an overall average of 117 mg ascorbic acid/100 g freshweight (gfw), 49 μg riboflavin/100 gfw and 65 μg thiamine per 100 gfw. Among sampling dates ascorbic acid (AA) levels differed significantly, but levels of riboflavin and thiamine did not. The range of variation of the mean concentration of total AA, riboflavin, and thiamine for all marketing levels were 3.4%, 36%, and 11%, respectively. None of these variations among marketing levels, however, was statistically significant. This study supports the hypothesis that average concentrations of vitamins do not change significantly from wholesale marketing to consumption, but significant variations do occur among individual market samples.
