Overview

Masato is a traditional fermented cassava beverage widely consumed by Indigenous communities in the Amazon basin. It is produced through spontaneous fermentation of cooked cassava mash and consumed as a mildly alcoholic drink.

Raw Materials

  • Cassava roots (Manihot esculenta)
  • Water
  • Environmental microorganisms

Fermentation Process

Cassava roots are peeled, cooked, and mashed into a paste. The mash is mixed with water and allowed to ferment naturally at ambient temperature for 1–3 days. Traditional preparation may involve mastication to introduce fermentative microorganisms.

Microbial Ecology

Fermentation is dominated by:

  • Yeasts
  • Lactic acid bacteria

These microorganisms convert carbohydrates into ethanol and organic acids, contributing to flavour and preservation.

Functional and Nutritional Aspects

  • Partial detoxification of cassava
  • Production of ethanol and organic acids
  • Provides energy and hydration

Cultural Significance

Masato is central to social interaction and daily life in Amazonian Indigenous cultures and is often shared during communal gatherings.
