Cupuassu (Theobroma grandiflorum Schum) is an amazon fruit, that each year is conquering more space in national and international market with the commercialization of its pulp. Its seeds, considered as subproducts, are arousing interest not only in the scientific world but also in the industry. It's known that from those seeds, it can be obtained analogous products as those cocoa seeds, following the same stages of processing. Among those products there is the cupuassu liquor, similar to cocoa liquor that is one of the ingredients of the chocolate formulation. The objective of this work was to study the physical, chemical and physico-chemical acquisition and characterization of cupuassu liquor. Three samples of cupaussu liquor were obtained, each one coming from a fermentation lot. Each lot was subjected to centesimal composition and rheological study. The cupuassu liquor presented high content of fat (63.93 to 66.51%) and caloric value (677.35 to 691.17kcal/100g). Its protein content varied from 8.95 to 10.31%. Its Casson plastic viscosity diminished as the temperature increased. The distribuition of the particles sizes influenced in the viscosity differences among samples. A higher reduction of plastic viscosity was found with the increase of temperature in the samples that presented bigger participles diameter. The cupuassu fat presented Newtonian behavior at 40ºC.
