Four vitamins were analyzed in several fruit and vegetable commodities to evaluate the differences between fresh and frozen produce. Ascorbic acid, riboflavin, α-tocopherol, and β-carotene were evaluated in corn, carrots, broccoli, spinach, peas, green beans, strawberries, and blueberries. Samples of each commodity were harvested, processed, and analyzed for nutrient content at three storage ti...

Moreover, the promptness and simplicity of one-sided auctions are beneficial for trading in perishable commodities. However, sellers cannot participate in the price-making process in these auctions.
