Overview

Tucupi is a traditional fermented cassava juice from the Amazon region of Brazil. It is produced from the liquid extracted during cassava processing and is used as a base for soups and sauces.

Raw Materials

  • Bitter cassava roots (Manihot esculenta)
  • Water

Fermentation Process

Cassava roots are grated and pressed to extract juice. The liquid is allowed to ferment spontaneously for 1–3 days, followed by boiling to inactivate residual cyanogenic compounds and stabilize the product.

Microbial Ecology

Fermentation is dominated by lactic acid bacteria, which:

  • Lower pH
  • Contribute to flavour development
  • Improve microbiological safety

Functional and Nutritional Aspects

  • Detoxification through fermentation and heat treatment
  • Acidic flavour profile used in culinary applications
  • Preservation of cassava-derived nutrients

Cultural Significance

Tucupi is central to Amazonian cuisine and is traditionally used in dishes such as pato no tucupi, reflecting Indigenous cassava-processing knowledge.
