Yacon syrup
Yacon syrup suppliers and sourcing guide
Yacon syrup is a dark, molasses-like syrup made from the tuberous roots of yacon (Smallanthus sonchifolius), an Andean plant in the sunflower family grown mainly in Peru and neighboring countries. The roots are washed, peeled and pressed, and the juice is filtered and evaporated at moderate temperature to a syrup. Its sugars are largely fructooligosaccharides (FOS) along with fructose, glucose and sucrose, and the FOS share varies with harvest age, root storage and processing heat.

Forms and grades of yacon syrup
Suppliers sell different products under the same name. Specify the one you need.
Standard syrup
Evaporated yacon juice sold by Brix, often with a stated minimum FOS content.
Organic
Syrup from certified organic yacon, the most common grade in retail and natural products.
Yacon powder
Dried, milled yacon root or dried syrup on a carrier, for dry mixes and capsules.
FOS-standardized syrup
Syrup sold against a declared minimum FOS percentage measured by HPLC, which makes lots easier to compare.
What to check on the COA
Compare each result with your own specification when the lot arrives.
- FOS and sugar profile (HPLC)
- Fructooligosaccharides, fructose, glucose and sucrose by HPLC; FOS falls with heat and age, so this is the key test.
- Brix
- Soluble solids by refractometer, which sets stability and dosing.
- Heavy metals
- Lead, cadmium and arsenic by ICP-MS, important for root crops from mineral-rich soils.
- Microbiology
- Total plate count, yeast and mold, since syrups made at low temperature receive less heat treatment.
- pH and acidity
- pH and titratable acidity, which flag fermentation in storage.
Storage, lots and expiry
Storage and shelf life
Keep yacon syrup sealed in a cool place away from light and follow the supplier's instructions on refrigeration after opening, since it can ferment if diluted or contaminated. FOS slowly breaks down to simple sugars with heat and time, so warm storage changes the sugar profile. Shelf life is set by the supplier's specification, with FOS and micro rechecked on older stock.
Lots and expiry dates
FOS content and color vary with harvest, how long roots were stored before pressing and evaporator temperature, so record the HPLC sugar profile and Brix for each lot. Note the country of origin and organic certificate details, since supply comes from a small number of Andean producers.

What forms of yacon syrup can brands buy?
Common forms include standard syrup, organic, yacon powder and fOS-standardized syrup. Ask each supplier for the specification sheet of the exact grade they quote.
What should the COA for yacon syrup include?
Expect fOS and sugar profile (HPLC), brix, heavy metals, microbiology and pH and acidity, each with its method, specification and result for that lot.
How should yacon syrup be stored?
Keep yacon syrup sealed in a cool place away from light and follow the supplier's instructions on refrigeration after opening, since it can ferment if diluted or contaminated. FOS slowly breaks down to simple sugars with heat and time, so warm storage changes the sugar profile. Shelf life is set by the supplier's specification, with FOS and micro rechecked on older stock.
