“…For this reason, mate aqueous extraction is an important industrial operation that has to be better investigated. In fact, according to our knowledge, a limited number of studies are focused on the scientific and technological aspects of this process (Sambiassi et al . 2002; Linares et al .…”

Experiments were carried out to investigate the kinetics of infusion of mate leaves. A cylindrical batch extractor made of glass and equipped with a mixer was operated at temperatures between 18 and 80C with comminute leaves of mate in the size range from 4.9 ¥ 10 -4 to 5.7 ¥ 10 -4 m. The experimental kinetic curves of solute concentration in the aqueous phase revealed a diffusion coefficient of soluble species through the leaves in the magnitude of 10 -12 -10 -13 m 2 /s. A negligible influence of agitation and significant effects of solvent temperature and particle size on the rate of extraction of soluble matter were experimentally observed. The kinetics of infusion of mate leaves and the influence of the investigated factors were correctly reproduced by two simplified differential equations referred to as the equilibrium-dependent and diffusion-dependent extraction models. PRACTICAL APPLICATIONSAround US$1 billion is the overall value that emerged from the activities of cultivation, manufacturing and trade of mate leaves involving more than 70 countries across the continents. Despite these positive aspects, the aromatic and bioactive properties of mate could be better explored to obtain several commercial derivatives that would increase the economic impact of this commodity at a global scale. However, the development of most of these new products depends on the availability of the powder extract of mate, which is typically obtained by solid-liquid extraction with hot water. In this framework, the results obtained in the current investigation can be applied as a guideline to design and operate industrial units of mate extraction in order have a maximum extraction yield at the lowest operating cost. bs_bs_banner Journal of Food Process Engineering

“…There have not been any reports about the aqueous extraction kinetics of yerba mate; nevertheless, there are many studies about extraction kinetics of components of tea and coffee (Jaganyi and Madlala, 2000;Jaganyi and Price, 1999;Spitzer, 1993, 1994;Spiro and Chong, 1997;Spiro and Jago, 1982;Spiro and Selwood, 1984;Stapley, 2002;Zanoni et al, 1992), metabolites extraction kinetics as phenolics, antioxidants and fat substances in other products (Bucić -Kojić et al, 2007;Cacace and Mazza, 2003;Franco et al, 2007;Herodež et al, 2003;Ho et al, 2005;Jaganyi and Wheeler, 2003;Kashyap et al, 2007;Wongkittipong et al, 2004) and a report on yerba mate extraction optimization (Sambiassi et al, 2002). There are several kinetics models for the interpretation of experimental extraction data.…”

“…Esta espécie também apresenta grande importância cultural, sendo consumido nos países sul-americanos em função da tradição adquirida das populações nativas (CARDOZO JUNIOR;MORAND, 2016). O principal modo de consumo da erva-mate é na forma de chimarrão e chás, porém, as folhas apresentam outras diversas aplicações industriais, tais como extratos solúveis para bebidas, corante, conservante de alimentos e matéria-prima para produtos de higiene e cosméticos (SAMBIASSI; ESCALADA; SCHMALKO, 2002).…”

O objetivo deste trabalho foi avaliar o efeito de épocas do ano e de clones na produtividade das minicepas e no enraizamento de miniestacas de erva-mate (Ilex paraguariensis A. St. - Hil.) tratadas ou não com ácido indolbutírico (AIB). Com esta finalidade, nas quatro épocas do ano realizou-se a coleta de brotos das minicepas de quatro clones de erva-mate, sendo que em cada coleta foi avaliada a porcentagem de sobrevivência das minicepas e o número de miniestacas. Posteriormente, os brotos foram seccionados em miniestacas de gema única, as quais foram ou não tratadas com 2000 mg L-1 de AIB. Aos 30 e 60 dias foram avaliadas as porcentagens de sobrevivência, enraizamento e calogênese, número e comprimento das raízes. As minicepas dos quatro clones de erva-mate apresentaram alta sobrevivência, além de produção constante de miniestacas dos clones 06SM17, 06SM12 e 06SM15 durante as quatro épocas do ano. O tratamento com AIB não incrementou no enraizamento das miniestacas de erva-mate. O processo rizogênico das miniestacas variou conforme o genótipo e a sazonalidade. O clone 06SM15 apresentou a maior capacidade rizogênica nas quatro épocas do ano. As melhores porcentagens de enraizamento foram verificadas nas épocas do outono e/ou inverno para os quatro genótipos avaliados.
