Fresh-market vegetable supplies have been sporadic following several December freezes in Florida, periods of cool, wet weather in coastal California, and several periods of subfreezing temperatures in California and Arizona. In addition, Mexican vegetables were damaged by a 2-day freeze in early February (extent of damage is unknown at this time). As a result, vegetable prices are now at or above the highs experienced a year earlier.

Your rating: None

‘Marathon’ broccoli (Brassica oleracea L. var. italica) florets were stored in air, low O2 (0.25%, 0.5%, and 1 %) or high CO2 (3%,6%, and 10%) at 0, 5, and 10C. Oxygen consumption and CO2 production were reduced under low O2 or high CO2 atmosphere, the reduction being greater at lower O2 and higher CO2 levels. NO differences were found in ethylene production among the different atmospheres.

Your rating: None

Acetaldehyde, ethanol and non-protein bound amino acids were determined in broccoli florets (Brassica oleracea L. var. Italica cv. Marathon) stored for 7 days at 10°C in air or controlled atmospheres (0.125, 0.25, or 0.5% O2 alone or in combination with 20% CO2, or 20% CO2 in N2) followed by 2 days aeration. Floret yellowing was visible at days 7 and 9 in air. Low O2 or low O2 plus high CO2 atmospheres delayed yellowing.

Vegetables and Melons Outlook December 2010

0
No votes yet
Your rating: None

Fresh vegetables: Prior to the recent freezing temperatures in Florida, the outlook for fresh vegetables this winter indicated improved yields and supplies. At the same time, demand was expected to remain sluggish as consumers remain conservative, especially with regard to away from home meals. Assuming freeze damage is less severe than last January, the winter price outlook generally favors prices that are historically strong but average just below the freeze-affected highs of a year earlier.
