TS 13568 Soft Drinks

In the TS 13568 standard developed by the Turkish Standards Institute (TSE), the requirements for soft drinks offered to consumers are explained and test methods are presented.

Soft drinks are generally produced by mixing three basic components: syrup (nectar), water and carbon dioxide. Different types of sugar are used to make the syrup, such as sucrose, fructose or sweeteners. The composition of this sugar solution is considered a trade secret. The water and syrup are then mixed in extremely precise proportions. The final step in the process is carbonation of the beverage by adding carbon dioxide. Various acidifiers, flavorings and coloring agents are included in the industrial production of soft drinks.

For the purposes of the TS 13568 standard,

• The expression of fruit nectar is defined as the natural fruit juice or fruit juice concentrate or their mixture obtained in accordance with the technique, from the whole or at most cut fruit, with the addition of drinkable water, sugar or honey and one or more of the additives in accordance with the relevant legal regulations. It refers to beverages prepared and made stable by heat treatments or other non-thermal physical treatments.
• The expression fruit ratio expresses the percentage by mass of fruit juice with the minimum natural sugar content in fruit nectar.
• Foreign substance expression refers to all kinds of visible substances other than those allowed to be used in the production of fruit nectar.

Sensory, chemical and microbiological properties of fruit nectar are defined in the standard.

The main tests that need to be carried out within the framework of the TS 13568 standard and the international standards on which these tests are based are as follows:

• Determination of lactic acid (EN 12631)
• Ethyl alcohol determination (ISO 2448)
• Determination of hydroxymethylfurfural (ISO 7466)
• Determination of sorbic and benzoic acid (ISO 22855)
• Determination of fruit ratio
  • Determination of potassium, calcium and magnesium (EN 1134)
  • Determination of phosphorus (EN 1136)
  • Formol number (EN 1133)
• Volatile acid determination (ISO 6632)
• Lead determination (EN 14084)
• Determination of mesophilic aerobic bacteria count (ISO 4833)
• Determination of mold and yeast count (ISO 21527)
• Coliform bacteria determination (ISO 4831)
