Dilution, PH and Brix Degrees
Next we will present the dilution, pH and brix degrees recommended for some fruit.
Pulp: Water
Guanabana Dilution 1: 3.5 - 4 PH 3.5 Brix degree 13
Orange Dilution 1: 4 - 5 PH 3.5 Brix degree 13
Peach Dilution 1: 2.5 – 3 PH 3.8 Brix degree 12.5 – 13
Tamarind Dilution 1: 10 – 12 PH 3.8 Brix degree 15
Mango Dilution 1: 2.5 – 3.5 PH 3.8 Brix degree 12.5
Cactus Fruit Dilution 1: 3 – 3.5 PH 3.8 Brix degree 13
Passion Fruit Dilution 1: 2 – 2.5 PH 3.5 Brix degree 13
Pineapple Dilution 1: 2 – 3.5 PH 3.5 Brix degree 12.5 – 13
Apple Dilution 1: 2 – 3.5 PH 3.8 Brix degree 12.5 – 13
Red Grape Dilution 1: 2.5 – 3.5 PH 3.8 Brix degree 13
During the standardizing process you will need to keep the following in mind: pH is regulated by adding citric acid. Generally, it should be under 4.5, since too much acid destroys microorganisms.
The amount of sugar (brix degrees) is regulated by adding white refined sugar.
Lets imagine you want to make pineapple nectar of 12.5 brix degrees and that you have the following:
Weight of the pulp: 14 kilograms Recommended dilution (pulp: boiling water): 1: 2.5 Water added: 35 liters Diluted brix degree: 3
Then you can determine the amount of sugar you will need to add by a balance of solids:
(14 + 28) + x(100) = (x + 14 + 35) (12.5) 126 + 100x = 12.5 x + 612.5 x = 5.56 kilograms of sugar
The recommended stabilizing proportion is of 0.5% at most (5 grams or one teaspoon per liter of diluted juice). As far as the preservative goes, it is included at 0.1% at most (1 gram per liter of diluted juice), of sodium benzoate.
Homogenizing Homogenizing allows the ingredients to become united. One way is to stir the pulp until dissolving and mixing the added ingredients and the rest of the ingredients. This homogenized mixture is then heated, before it reaches a pasteurization temperature.
Pasteurizing This is done in order to destroy the microorganisms. It can be done by heating the mixture.
- At 85 degrees C. for 5 to 10 minutes
- At 97 degrees C. for 30 seconds and cooling it quickly
- At 60 degrees C. for 30 minutes.
