Blueberries for Fresh Eating and Processing

By Harold Stewart

Introduction

Tasty fresh blueberries are a favorite summertime delight to many people across the country. Fresh blueberries are in season during the summer months, and are available frozen all year around.

In the summer warm temperatures make harvested blueberries extremely perishable. They can decline rapidly in quality if not cooled soon after picking. Warm, ripe blueberries can leak, juice as a result of rough handling. This provides ideal conditions for decay to start right after they are picked. Shelf- life investigations have established remarkable reductions in decay are possible by rapid and thoroughly cooling blueberries right after they are picked. Cooling slows down the inevitable decline in quality after picking. You should cool blueberries as soon as possible after being picked and always if possible, within 4 hours of being harvested.

As may be expected, there are distinct differences between different blueberry varieties. Some varieties will keep much longer than other varieties. The following list is some of the blueberry varieties and their shelf life after picking and stored under refrigeration. Some such as Bluegold and Legacy have exceptional shelf lives. Both of these blueberry varieties also have outstanding flavor. This makes them particularly good for fresh eating and storage for a time while they are being eaten over a month after picking.

When selecting blueberries to grow in your garden shelf life and flavor are two qualities you may wish to consider. There are of course of factors that may be important to you such as antioxidant levels. The use of the berries such as baking in muffins, using to make jams etc. Small berries usually have higher levels of antioxidants than other varieties and are also a good size for use in baking such thing as muffins, and pancakes. Top Hat and Rubel are examples of wild blueberries with very high levels of antioxidants and also of a size favorable for using in baked goods. Duke is an example as shown in research trails that is exceptional for making good blueberry jam.
