How to sweeten fruits the natural way.

Even the same species of plant can have fruits that taste differently from each other. The reason why fruits are sweet is due to the presence of monosaccharides. Monosaccharide is the simplest form of sugar or carbohydrate. Carbohydrates are the main source of energy for the body. When unused, carbohydrates are stored in the body as fats.

Monosaccharide is derived from the Greek words "mono" which means "single or one", and "sacchar", meaning "sugar". The common monosaccharides are glucose (also called dextrose), fructose, and galactose. The type of sugar found in fruits is fructose. For humans to use fructose from fruits, this has to be converted into glucose by the liver. Glucose provides the energy needed by the body to perform its metabolic processes.

Some fruits can be sweeter than others because those fruits pack more sugar in them. But there are ways to sweeten fruits the natural way. Fermented fruit juice can be prepared to do the trick. The following procedure details the steps in preparing the mixture. 

How To Make The Concoction Of Fermented Fruit Juice

Ingredients and Materials Needed

In preparing the fermented fruit juice, you will need the following ingredients:

  • Any of the following fruits may be used in preparing the fermented fruit juice: banana, mango, papaya, avocado or squash
  • Clay jar
  • 1 kilo of crude sugar
  • Clean sheet of paper
  • String


  1. Chop one kilo of fruit. Include the skin and the seeds.
  2. Put the chopped fruit into the clay jar and mix with one kilo of crude sugar.
  3. Cover the mouth of the clay jar with a clean sheet of paper and tie firmly with a string.
  4. Place the clay jar in a cool and shaded place.
  5. Let ferment the mixture for seven days. The whole thing will produce approximately two and a half liters of fermented fruit juice.

How To Use The Concoction

Just mix two tablespoons of the juice to one liter of water. You may add indigenous microorganisms (IMO) to the mixture (see How To Make A Concoction of Indigenous Microorganisms). Spray the resulting mixture directly to the leaves and soil of fruit-bearing trees. 

The concoction will naturally sweeten fruits.
