Keeping Produce Fresh at Markets and Farm Stands

May 6, 2020 - From Issue:
By:

Farmers markets and farm stands will be opening soon if they aren’t already open. Vendors and market managers will be implementing new practices to reduce the spread of the novel corona virus. Guidelines for practices at Indiana farmers markets are summarized in a new publication from Purdue in cooperation with Indiana State Department of Health, Indiana Grown, and other organizations. In addition to getting familiar with these new practices, it’s a good time to review ways to keep produce fresh between harvest and sale. Vegetables quickly lose quality after harvest if not properly cooled and stored. Cooling slows biochemical processes in the harvested produce, helping to maintain flavor and minimize decay. Preventing water loss by maintaining appropriate relative humidity reduces weight loss and shriveling or wilting. Even when post-harvest care at the farm is adequate, keeping produce fresh at a farm stand or farmers market can be a challenge. Vegetables[Read More…]

Harvest and Postharvest Storage of Pumpkins and Winter Squash

With the start of pumpkin harvest, it is a good time to review important considerations for harvest and postharvest storage of pumpkins and winter squash (butternut, acorn and hubbard squash etc.). Pumpkin and winter squash should be harvested fully mature to reach their optimal quality and fulfill their potential for long shelf lives. Characters indicating fruit maturity include loss of rind surface gloss, ground spot yellowing, and hardening of the skin to the level that it is resistant to puncture with a thumbnail. Except for some striped varieties, mature fruit should have solid external color. If fruit have to be harvested pre-mature because of plant decline, these fruit won’t store as well as mature fruit. The best practice is to harvest the fruit as soon as they are fully mature and then store under proper conditions. If mature fruit are left attached to the vines, it increases the chance of[Read More…]

Optimal Storage Conditions for Vegetables

July 20, 2017 - From Issue:
By:

After harvest, storing vegetables in optimal conditions is important to ensure the whole season’s hard work has paid off. This article discusses the optimum storage conditions for tomato, pepper, cucumber, watermelon, cantaloupe and sweet corn. Tomato Ideal storage conditions for tomatoes depend on the maturity stage of picking. If tomatoes are picked at mature green, store them in 66 to 70°F with 90 to 95% RH would encourage uniform ripening. Temperatures above 81°F reduce intensity of red color and reduce fruit shelf-life. Green tomatoes are chilling sensitive. If the temperature is below 55°F, fruit may develop chilling injury. Red tomatoes are safe to store at 50°F, however, flavor and aroma may be negatively affected compared to storing them at 55°F. Pepper Optimum storage condition for peppers is 45 to 55°F with 90 to 95% RH. Temperatures lower than 45°F may cause chilling injury. Colored peppers are in general less chilling[Read More…]

Harvest and Post-harvest Care for High Quality Pumpkins

​Pumpkin season is here. Keeping up with best management practices through harvest and storage will help the year wrap up on a good note. The steps below are a reminder of actions that can make a difference. Handle fruit as little as possible. Harvest fully orange and healthy pumpkins. Half-orange pumpkins may turn orange but quality and storage life will be reduced. Use a sharp knife or loppers to cut pumpkins from the vine. Leave stems long enough for an attractive product. Carry the pumpkin like a ball, not by the stem, or ‘handle.’ Brush off soil that sticks to the pumpkin. If pumpkins are washed, include a labeled sanitizer in the wash water and dry pumpkins before storage. Place pumpkins carefully in crates, bins, or trucks, so that the stem of one pumpkin doesn’t damage the rind of another. Watch for and avoid (or pad) sharp edges that could[Read More…]
