Osmotic Gap Calculation

Osmotic Gap (%) = (Total Solids - Total Sugars) / Total Solids × 100

Where:
- Total Solids: The percentage of soluble solids in the fruit juice
- Total Sugars: The percentage of sugars in the fruit juice

What is Osmotic Gap?

The osmotic gap is a measure used in fruit juice analysis to indicate the difference between the total soluble solids and the total sugars. It helps in understanding the composition of fruit juice and is particularly important in the food industry for quality control and processing purposes.

How to Use This Calculator

  1. Enter the Total Solids (%) in the fruit juice. This represents the percentage of all soluble solids in the juice.
  2. Enter the Total Sugars (%) in the fruit juice. This represents the percentage of sugars in the juice.
  3. Click the Calculate button to compute the osmotic gap.
  4. The result will be displayed in the Osmotic Gap (%) field.

Interpreting Results

A higher osmotic gap indicates that there are more non-sugar soluble solids (such as acids, pectins, and minerals) in the fruit juice. This can affect the texture and flavor of the juice. The osmotic gap is particularly important in the production of concentrates, where water is removed, and in the development of fruit-based products.

Example

If a fruit juice has a total solids content of 15% and total sugars content of 12%, the osmotic gap would be calculated as follows:

Osmotic Gap = (15% - 12%) / 15% × 100 = 20%

This means that 20% of the soluble solids in the juice are non-sugar components.
