Drying bananas

Bananas are among the more popular home-dehydrating products to make. They are inexpensive at any time of year, can often be bought on sale, and it’s easy to turn them into a successful, multi-use dried product.

Directions

Here we compare directions from three different sources.

For information on making the dips mentioned below, see Fruit dry-pretreatments .

 

Ball Blue Book

Preparation:  “Peel and cut into ¼- to ½- inch (½ to 1 cm) inch slices.”

Pretreatment: “Pretreat with Fruit-Fresh by dipping, if desired.”

Temperature: 130 to 135 F (54 to 57 C)

Time: Until pliable to almost crisp.

Notes: “Choose any large, slightly brown-speckled yellow variety.”

Water content: 76%. (Used if doing a Dehydration Weight Test.)

Reference: Ball Blue Book, 37th edition, 2014. Page 164.

Note: Ball All New (2016) says “Choose large fruit with a few brown spots. Peel, cut into ¼- to ½- inch (½ to 1 cm) slices. Treat with Ball Fruit-Fresh.” Dry until “pliable with crisp edges.” (Page 336)

 

 

Excalibur

Preparation:  “Peel the bananas and cut into ⅛″ to ¼″ (¼ to ½ cm) slices. Cut away any bruised portions.”

Pretreatment: “Bananas may be sprinkled with fruit flavoured gelatin powder or lemon juice. Honey dip for crisper slices.”

Temperature: 135 F / 57 C

Time: “Until leathery.” (6 to 10 hours based on humidity conditions where you are.)

Notes: “Large yellow varieties, like Cavandish or Martinique, dehydrate best. Those that are all yellow or lightly brown specked will be the sweetest; avoid green or overripe bananas.”

Quality: Excellent

So Easy To Preserve

Preparation: “Peel and slice ¼ inch to ⅜th inch (½ to ¾ cm) thick, crosswise or lengthwise.”

Pretreatment: Sulfur smoke 2 hours OR steam blanch 3 to 4 minutes OR syrup 10 minutes OR honey dip, ascorbic acid, Fruit Fresh, fruit juice, or, sulfite dip.

Temperature: 140 F / 60 C

Time: 8 to 10 hours

Notes

Here’s a FAQtoid on banana chips from the National Center for Home Food Preservation:

Q: My banana chips don’t taste like the ones in the stores. What can I do?

A: There are a variety of banana chips available. Read the ingredients on the label. Some bananas are dipped in honey; some are dipped in granulated sugar, brown sugar or flavored gelatin. Be sure bananas are ripe. Some commercial banana chips have been treated to make them crisp. This cannot be done in the home.” ^[1]NCHFP Drying FAQ. Accessed January 2018.
