HISTORY

The guava is believed to have originated in an area extending from southern Mexico into Central America. Since 1526, it has been common throughout all warm areas of tropical America, the West Indies, the Bahamas, and Bermuda. It was introduced to Florida in 1847 and was brought from there to the East Indies and Guam. It is likely that it spread from those regions to Asia and Africa. It was introduced to Hawaii in the early 19th century and is now common throughout the Pacific islands.

HOW TO SELECT AND STORE

Selection: Guavas are available in different varieties such as the Chinese Guava, Strawberry, Lemon, Apple and Mountain Guava. In tropical regions, they are available all the year round.

On ripening, the skin of the guavas generally turns from green to yellow, their flesh softens and they develop a fragrant fruity aroma. While purchasing guavas, make sure that you choose fresh fruits with their skins intact without any cuts, bruises or patches. Your choice of guava also depends upon the variety that you are buying. If you are buying pink guavas, choose the ones that are firm and devoid of soft spots. Their skin should be green with a yellow tinge. While buying white Thai guavas, make sure that they are free from blemishes or soft spots and their skin should be bright green in color, like a Granny Smith apple. Overly soft guavas or the ones with soft spots or discoloration should be avoided. 

When the guavas are picked from the tree, they are mature but not ripe. In other words, though the fruit has reached its optimum size and shape, the starches present in it have not been converted into sugar. These starches will get converted into sugar after a few days which will cause the fruit to soften and emit a wonderful guava fragrance. Ripe guavas generally have a characteristic color and aroma. 

Storage: Guavas can be stored at room temperature for a few days. Mature but green guavas can last for 2 to 5 weeks when kept at a regulated temperature between 46F and 55F and relative humidity of 85% to 95%. To hasten ripening, the guava can be kept wrapped in a paper with a banana or apple.

Fully ripe guavas can be refrigerated for a few days. Pink and white guavas yield to gentle pressure if they are ripe. Ripe guavas can be kept in plastic bag or container and refrigerated for a few days. It is advisable to use them within a day or two. Unripe guavas can be stored in a plastic container or bag and can last for about two weeks.  

Freezing the guavas can make them last longer, even up to a year. To freeze a guava, cut it and place it in a freezer container. Cover it with light simple syrup and provide a little extra space in the container for expansion.
