the sweetner

Example: Production of adjuncts for brewing of beer in Africa

For the time being major syrup producers are hesitant to start local syrup production in African developing countries, while simultaneously local governments lack required currencies to import raw materials against fast rising food prices. Local farmers have potential to grow cassava however infrastructure necessary for transport and in-time processing of cassava roots fails.

Mobile cassava processing units or small scale starch factories for which tapioca sales are guaranteed by multinationals who produce locally may overcome this stalemate.

During last year HENAN Food Systems developed THE SWEETNER, an innovative concept for in-line production of maltodextrins and starch sugars. Raw materials that can be processed vary from all types of starch to a wide variety of starch containing biomass. Depending on local - and seasonal availability of raw materials brewers now have flexibility to choose individually for their most feasible option.

Pilot scale experiments executed by HENAN Food Systems resulted in proof of concept for in-line conversion of tapioca into high dextrose syrup and high conversion syrup with standard sugar and high maltose profiles. These syrups are widely used and immediately allow global entrance at breweries.

A sturdy skid construction facilitates flexible integration of THE SWEETNER in existing breweries. In close co-operation with our customers we engineer our machines tailor-made. This approach guarantees optimal conversion performance in any production process.

Unique selling propositions

Advantages of in-line conversion of tapioca into high maltose syrup as adjunct in beer are:

  • Good, stable microbiological quality of raw materials
  • Besides tapioca a broad range of alternative raw materials can be converted
  • Use of locally cultivated crops stimulates African economies and allow rural farmers to generate sustainable incomes
  • Development of rural areas boosts local economies and stimulates beer consumption
  • No cyanides in case tapioca is used
  • Cost price reduction for high maltose syrup
  • Our flexible concept may facilitate other innovations such as very high maltose syrup
  • Absence of beta glucans during mashing and lautering
  • Tax reductions up till 30 % for final beer, due to local sourcing of raw materials
  • Fast building of market share in emerging African markets
  • Our units are installed on the site of the customer and will be operated by the brewer

Price in US$ per MT
Raw materials (starch at $465/MT, DIP) 495
Utilities (steam, water, electricity) 38
Labor 15
Depreciation cost (20%, 5000 running h/y) 24
Total cost maltose syrup (dry matter) 600
Investment estimate excl. installation costs $ 600.000
The native starch is suspended into a "starch milk dispersion" with a concentration of approx. 38% dm. The slurry is fed to the conversion installation. Native tapioca starch will allow a very stable process.
